Paul Ramsey: Christy Clark's $1M Faux Conference Photo-op

OSGeo Planet - Mon, 2017-03-06 20:00

On February 25, 2013, Christie Clark mounted the stage at the “International LNG Conference” in Vancouver to trumpet her government’s plans to have “at least one LNG pipeline and terminal in operation in Kitimat by 2015 and three in operation by 2020”.

Christy Clark's $1M Faux Conference Photo-op

Notwithstanding the Premier’s desire to frame economic devopment as a triumph of will, and notwithstanding the generous firehosing of subsidies and taxbreaks on the still nascent sector, the number of LNG pipelines and terminals in operation in Kitimat remains stubbornly zero. The markets are unlikely to relent in time to make the 2020 deadline.

And about that “conference”?

Like the faux “Bollywood Awards” that the government paid $10M to stage just weeks before the 2013 election, the “LNG in BC” conference was a government organized “event” put on primarily to advance the pre-election public relations agenda of the BC Liberal party.

In case anyone had any doubts about the purpose of the “event”, at the 2014 edition an exhibitor helpfully handed out a brochure to attendees, featuring an election night picture of the Premier and her son, under the title “We Won”.

We Won

The “LNG in BC” conference continued to be organized by the government for two more years, providing a stage each year for the Premier and multiple Ministers to broadcast their message.

The government is no longer organizing an annual LNG confab, despite their protestations that the industry remains a key priority. At this point, it would generate more public embarassment than public plaudits.

Instead, we have a new faux “conference”, slated to run March 14-15, just four weeks before the 2017 election begins: the #BCTech Summit.

Like “LNG in BC”, the “BCTech Summit” is a government-organized and government-funded faux industry event, put on primarily to provide an expensive backdrop for BC Liberal politicking.

BC Innovation Council

The BC Innovation Council (BCIC) that is co-hosting the event is itself a government-funded advisory council run by BC Liberal appointees, many of whom are also party donors. To fund the inaugural 2016 version of the event, the Ministry of Citizens Services wrote a direct award $1,000,000 contract to the BCIC.

The pre-election timing is not coincidental, it is part of a plan that dates all the way back to early 2015, when Deputy Minister Athana Mentzelopoulos directed staff to begin planning a “Tech Summit” for spring of the following year.

“We will not be coupling the tech summit with the LNG conference. Instead, the desire is to plan for the tech summit annually over the next couple of years – first in January 2016 and then in January 2017.” – email from A. Mentzelopoulos, April 8, 2015

The intent of creating a “conference” to sell a new-and-improved government “jobs plan”, and the source of that plan, was made clear by the government manager tasked with delivering the event.

“The push for this as an annual conference has come from the Premier’s Office and they want to (i) show alignment with the Jobs Plan (including the LNG conference) and (ii) show this has multi-ministry buy-in and participation.” – S. Butterworth, April 24, 2015

The event was not something industry wanted. It was not even something the BCIC wanted. It was something the Premier’s Office wanted.

And so they got it: everyone pulled together, the conference was put on, and it made a $1,000,000 loss which was dutifully covered by the Province via the BC Innovation Council, laying the groundwork for 2017’s much more politically potent version.

This year’s event will be held weeks before the next election. It too will be subsidized heavily by the government. And as with the LNG conference, exhibitors and sponsors will plunk down some money to show their loyalty to the party of power.

LNG BC Sponsors

The platinum sponsors of LNG in BC 2015 were almost all major LNG project proponents: LNG Canada, Pacific Northwest LNG, and Kitimat LNG. Were they, like sponsors at a normal trade conference, seeking to raise their profile among attendees? Or were they demonstrating their loyalty to the government that organized the event and then approached them for sponsorship dollars?

It is hard to avoid the conclusion that these events are just another conduit for cash in our “wild west” political culture, a culture that shows many of the signs of “systematic corruption” described by economist John Wallis in 2004.

“In polities plagued with systematic corruption, a group of politicians deliberately create rents by limiting entry into valuable economic activities, through grants of monopoly, restrictive corporate charters, tariffs, quotas, regulations, and the like. These rents bind the interests of the recipients to the politicians who create them.”

Systematically corrupt governments aren’t interested in personally enriching their members, they are interested in retaining and reinforcing their power, through a virtuous cycle of favours: economic favours are handed to compliant economic actors who in turn do what they can to protect and promote their government patrons.

Circle of Graft

The 2017 #BCTech conference already has a title sponsor: Microsoft. In unrelated news, Microsoft is currently negotiating to bring their Office 365 product into the BC public sector. If the #BCTech conference was an ordinary trade show, these two unrelated facts wouldn’t be cause for concern. But because the event is an artificially created artifact of the Premier’s Office, a shadow is cast over the whole enterprise.

Who is helping who here, and why?

A recent article in Macleans included a telling quote from an anonymous BC lobbyist:

If your client doesn’t donate, it puts you at a competitive disadvantage, he adds. It’s a small province, after all; the Liberals know exactly who is funding them, the lobbyist notes, magnifying the role donors play and the access they receive in return.

As long as BC remains effectively a one-party state, the cycle of favors and reciprocation will continue. Any business subject to the regulatory or purchasing decisions of government would be foolish not to hedge their bets with a few well-placed dollars in the pocket of BC’s natural governing party.

The cycle is systematic and self-reinforcing, and the only way to break the cycle, is to break the cycle.

GeoSolutions: Finalmente disponibile il profilo DCAT-AP IT per CKAN

OSGeo Planet - Mon, 2017-03-06 13:39


Dear Reader,

We apologize in advance, but this post is for our italian readers (hence in Italian only) to announce that we have finalized the implementation of the DCAT-AP_IT Metadata Profile leveraging on the CKAN Open Data product.

Siamo lieti di annunciare il primo rilascio dell’estensione CKAN per il supporto al profilo applicativo  DCAT-AP_IT nei portali open data italiani. Lo sviluppo è stato sostenuto, in uno sforzo congiunto, dalla Provincia di Bolzano/Sud Tirol e dalla Provincia di Trento ed è disponibile gratuitamente con licenza  AGPL v3.0.

Il profilo per la documentazione dei dati delle pubbliche amministrazioni (DCAT-AP_IT), reso disponibile dall’Agenzia per l’Italia Digitale (AgID), nasce con l’obiettivo di armonizzare i metadati con cui vengono descritti i dataset pubblici, al fine di migliorarne la qualità e favorire il riuso delle informazioni. L’estensione ckanext-dcatapit, sviluppata da GeoSolutions, è disponibile su una respository dedicata sotto il nostro account GitHub con un’accurata documentazione che aiuta a comprenderne le caratteristiche, i requisiti e le specifiche di installazione e configurazione (presto la repository sarà portata sotto l'egida di AgID). Le pubbliche amministrazioni italiane potranno quindi utilizzare l’estensione per rendere i propri cataloghi conformi al profilo italiano DCAT-AP_IT e favorire le pratiche di condivisione e standardizzazione con le altre PA del territorio italiano.

[caption id="attachment_3307" align="alignnone" width="515"]Scheda di visualizzazione del dataset Scheda di visualizzazione del dataset[/caption]

Grazie alla notevole esperienza acquisita dal team di sviluppo di GeoSolutions nella realizzazione di numerose estensioni per CKAN, nonché nell’installazione e configurazione di molteplici cataloghi che utilizzano questa piattaforma, l’estensione ckanext-dcatapit fornisce un insieme valido ed eterogeneo di funzionalità non solo per la creazione guidata di datasets, ma anche per l’integrazione di metadati provenienti da sorgenti esterne (CSW, RDF, JSON-LD) in conformità al Profilo Applicativo.

[caption id="attachment_3308" align="alignnone" width="515"]Form di modifica del dataset Form di modifica del dataset[/caption]

L’estensione ckanext-dcatapit è stata sviluppata con scrupolosa attenzione non solo in merito alle sue funzionalità caratteristiche e alla loro stabilità, ma anche per garantire la più alta compatibilità possibile con le altre estensioni spesso presenti nelle piattaforme CKAN installate. In aggiunta favorisce l’integrazione con eventuali estensioni custom che necessitano di definire campi aggiuntivi ai dataset. Anche gli aspetti legati al multilinguismo e la localizzazione dell’interfaccia sono stati affrontati e resi disponibili per garantire la massima usabilità da parte di quelle realtà che li necessitano, come per esempio le Provincie di Bolzano/Sud Tirol e Trento: l’estensione fornisce i propri files di localizzazione che aiutano a snellire eventuali personalizzazioni in questi termini, mentre l’estensione ckanext-multilang fornisce supporto per il multilinguismo dei contenuti presenti nel catalogo (dataset, organizzazioni, gruppi e altro).

[caption id="attachment_3309" align="alignnone" width="515"]Multilinguismo al lavoro Multilinguismo al lavoro[/caption] Di seguito un elenco delle PA che già usano ckanext-dcatapit:
  • Il portale OpenData della Provincia di Bolzano/Sud Tirol.
  • Il portale OpenData del Trentino.
  • L’infrastruttura federata OpenDataNetwork (per il momento ancora in test) per il capofila Città Metropolitana di Firenze, che raccoglie e distribuisce i dati di vari enti toscani tra cui: Città Metropolitana di Firenze, Provincia di Prato, Provincia di Pistoia ed Autorità di Bacino dell’Arno.
Invitiamo tutti coloro che sono interessati a partecipare allo sforzo per lo sviluppo di questa estensione o che fossero interessati ad utilizzare questa estensione a seguire il nostro blog o iscriversi alla nostra newsletter; raccomandiamo di visionare anche i nostri pacchetti di supporto professionale GeoSolutions Enterprise Support Services nel caso si volesse usufruire di un supporto attento e qualificato per la messa in produzione di questa estensione. Allo stesso modo vi invitiamo a visionare le informazioni sugli altri nostri prodotti Open Source quali GeoServerMapstore, GeoNode e GeoNetwork. The GeoSolutions team,

Fernando Quadro: 10 anos de GeoServer no Brasil

OSGeo Planet - Mon, 2017-03-06 10:30

Desde meados de 2016, por um convite recebido do Jody Garnett, estou escrevendo no Blog do GeoServer (em inglês). Em meu segundo post, resolvi relatar um pouco sobre os 10 anos que a comunidade GeoServer-BR está comemorando neste ano de 2017.

Tenho imenso orgulho de saber que tudo começou em 2007, através do curso que ministrei no III ENUM (Encontro Nacional de Usuários MapServer) em Brasília/DF.

Com o passar dos anos, é muito gratificante ver como o GeoServer está difundido no Brasil e como tem sido amplamente utilizado pelas empresas de todos os setores e portes, e também pelos órgãos governamentais que o adotaram como servidor de mapas oficial da INDE (Infraestrutura Nacional de Dados Espaciais).

Gostaria de agradecer a Boundless, que é a empresa mantenedora do GeoServer, além de todos que contribuíram de alguma forma nesses 10 anos para o crescimento e divulgação do GeoServer no Brasil.

From GIS to Remote Sensing: Update: Semi-Automatic Classification Plugin for QGIS 3

OSGeo Planet - Sun, 2017-03-05 10:51
QGIS is in the update process which should bring the version 3 in the second half of this year. This update will improve many aspects of QGIS, in particular with the upgrade to Python 3 and QT 5.
Consequently, all the plugins should migrate to Python 3 and QT 5, and adapt to the API breaks, in order to work in QGIS 3.

I have update of the Semi-Automatic Classification Plugin (SCP) to version 5.99 which runs in QGIS 3 (but not in QGIS 2). The tools of this version are the same as SCP version 5, but all the functions run with Python 3, QT 5, and are adapted to the new QGIS APIs.

Bjorn Sandvik: Creating a TIN from a raster DEM

OSGeo Planet - Sat, 2017-03-04 11:59
NB! This blog post will constantly change until I find a good open source solution to create a Triangulated Irregular Network (TIN) from a Digital Elevation Model (DEM). Would you like to help? Please add a comment below!

NEW! Read the first test of the TIN capabilities of SAGA GIS.

People have already helped on Twitter, and I'll include some of these suggestions in this post.
Help! Are there any good #opensource solutions to turn a DEM into a TIN? #gistribe #foss4g #gis #3d #postgis pic.twitter.com/YWV59HtNgW— Bjørn Sandvik (@thematicmapping) September 6, 2016
My example DEM of Jotunheimen in Norway can be downloaded here (144 MB GeoTIFF). This is the same dataset I've used previously for my terrain mapping experiments with three.js and Cesium.

The goal now is to turn this raster DEM into a nice triangulated irregular network (TIN) optimised for 3D rendering. 
The dream solution would be a command line tool (part of GDAL?) that can turn a raster DEM into an optimised TIN.

GeoServer Team: 10 years of GeoServer in Brazil

OSGeo Planet - Thu, 2017-03-02 15:42

This is a special year because the Geoserver Brazilian Community celebrates 10 years. It all started in 2007 with an GeoServer’ Course at III ENUM (event focused on MapServer) in Brasilia, federal capital, and since then the community has approximately 600 members and more than 5,000 messages exchanged during those 10 years.

During this time, GeoServer has been widely disseminated both in education, government and corporate. There are reports that large banking institutions, telecommunications and information technology companies in addition to governmental sectors such as IBGE (Brazilian Institute of Geography and Statistics), Embrapa (Brazilian Agricultural Research Corporation), IBAMA (Brazilian Institute of Environment and Natural Resources Renewables), among others, has used GeoServer in its various projects.


However, the most notable among his many successes was the establishment of GeoServer as the official map server of INDE (Spatial Data Infrastructure), in 2008 by then President Lula.

We would like to thank everyone who has contributed to the growth of GeoServer in Brazil, whether writing articles, giving lectures or simply encouraging the use of GeoServer within its institutions. A special thanks to Andrea Aime who implemented the projection used by Brazil.

Jo Cook: This is not a geo post

OSGeo Planet - Wed, 2017-03-01 12:02

TL;DR How not to burn out, or how I work, the 2017 edition

I’ve always suffered from anxiety and stress in my work. It’s a first-world problem, sure, but it’s there, and tangible, causing health issues (blood pressure high enough to frighten most health-care professionals, and surviving on approximately 3-4 hours sleep a night, most nights). Before Christmas 2016 I felt as if I was hitting some sort of tipping point, where I needed to fix things, or burn out. To add to that, I have a worsening back problem (Hyperlordodis of the lower spine, and a slipped disk) which has been slowly eroding my ability to do the things I love and keep me sane, like bouldering and scuba-diving.

Cut to 2 months later, and I feel as if I’m making a huge amount of progress and I put it down to a small number of minor changes. I’m setting them out in this post in the hope that they are useful to others. Warning, I’m going to mention meditation, but promise me you won’t stop reading at this point, as it’s not hippy claptrap.

I can’t say which of the things below is the key to getting myself back on track, but I am sleeping better, and am a whole lot less stressed, so for me it’s the whole package. If I thought that turning on the spot thrice widdershins four times a day was the key, I’d be doing that!

Blue Light on your phone/digital device

Seriously, cut this out before you go to bed. If you can’t stop using your device, then try something like Twilight to steadily reduce the brightness of your screen in the evening.


I’ve always been curious about the benefits of mindfulness, so I purchased a subscription to Calm a few years ago but wasn’t really using it very much. I now meditate for 10 minutes first thing in the morning and last thing at night. The simple fact of taking 10 minutes out to sit/lie quietly and concentrate on just breathing and not thinking is hugely beneficial.


I’m using Google Fit to track my daily progress in meditating and doing the exercises for my back, and shame me into keeping it going. I also use Remember the Milk to send me reminders in the morning and the evening- these come through to my Pebble watch so I have no excuse.

Digital Minimalism

Reading Cal Newport has led me to consider the value that I really get from social media. The balance I have found is to delete social media accounts that provide no use to me at all (hello LinkedIn and Facebook) and to drastically reduce the number of accounts I follow on Twitter. I’ve also cut down the number of apps that can notify me on my phone and hence my watch.


I think better on paper, always have, and have gone through a number of task management variants over the years. The main philosophy is always the same- I am a total convert to Getting Things Done but have tried many different ways of actually managing my lists. Before Christmas I heard about Bullet Journal and have now settled on a hybrid approach, using possibly my favourite notebook in the world- the Hobonichi Techo Planner. This is essentially an A5 gridded page a day diary with additional planning pages, and lovely paper that works well with a fine fountain pen and small writing. I dump every task I have to do in here, on the day it needs to be done, if not today.

gvSIG Team: New website and new documentation for users and developers in gvSIG

OSGeo Planet - Wed, 2017-03-01 09:08

We want to announce our new website for the gvSIG documentation. This website will contain all type of documentation such a user manuals, developer guides for Scripting, for Java, workshops and more. Also, it will contain other usefull links like related pages with the project.


seleccion_003For other hand, we want to announce that the user documentation for gvSIG desktop 2.3 in English is completed and it has been published.

There are also some progress in the translation of the Scripting Documentation and in the Quick Developer’s Guide, that you can access from the index of the documentation.

Speaking of translations, we are also almost done the Portuguese translation of the Scripting Documentation, which you can access from the index of the portuguese documentation.


To change between languages, in the top right corner you will find differents flags that will link you to a different languages indexes. If you can’t find the docs that you need, you can check first if they exist in other languages.

We want to use this opportunity to say thanks to all the translators that help us with this documentation and make a new call to new translators to help us with keeping all the docs updated.

gvSIG Team: Aprendiendo SIG con Juego de Tronos (XIII): Geoprocesamiento

OSGeo Planet - Wed, 2017-03-01 06:28

Las operaciones espaciales con datos geográficos para crear nueva información se conocen como Geoprocesos. Ejemplos de geoprocesos son obtener una nueva capa con las zonas de solape entre dos capas, una capa que sea el área de influencia a una determinada distancia de otra capa, un mapa de densidad de puntos, etc.

En gvSIG Desktop hay más de 350 geoprocesos. Tenemos muchos algoritmos listos para ser utilizados y ayudarnos a analizar nuestra información espacial.

En la ayuda hay mucha documentación sobre geoprocesamiento; los enlaces principales son:

Lo primero que debéis saber es que se accede a las distintas herramientas de geoprocesamiento a través del menú “Herramientas/Geoprocesamiento/Caja de herramientas” o a través de su botón correspondiente:200_got

Desde la caja de herramientas vamos a poder realizar cualquiera de los geoprocesos disponibles en gvSIG Desktop. En nuestro caso vamos a hacer dos geoprocesos distintos.

Empezaremos realizando un enlace espacial entre la capa “Locations” y la capa “Political”. Si consultamos la ayuda de este geoprocesos, nos indica que hace lo siguiente: “El enlace espacial permite transferir los atributos de una capa a otra basándose en una característica espacial común”. 201_got

Si observamos la imagen anterior, e imaginamos que la capa de polígonos es “Political” y la de puntos “Locations” parece claro cual será el resultado: una nueva capa de puntos que contendrá entre sus atributos los heredados de la capa “Political”. Vamos a ello…

Lanzamos la “caja de herramientas” y buscamos el geoproceso de “Enlace espacial”. Si no sabemos donde se ubica podemos utilizar el buscador de la parte inferior de la ventana, introduciendo un texto como “enlace”. 203_got

Vamos a utilizar el primero de los geoprocesos filtrados. Para ejecutarlo hacemos doble clic sobre él o pulsamos sobre él el botón secundario del ratón y seleccionamos la opción “Ejecutar” en el menú contextual que nos aparece. Se mostrará una ventana como la siguiente:204_got

Como “Capa de entrada” seleccionamos “Locations”. Como “Capa de revestimiento” seleccionamos “Political”. Si tenéis dudas de como funciona un geoproceso…consultar su ayuda (además de en el manual, está disponible pulsando el botón de información de la parte inferior derecha de la ventana del geoproceso).

Si no le indicamos que nos guarde la capa, generará una capa temporal (es decir, se perderá una vez cerremos el proyecto). Por lo que si quieres conservar la capa resultado debes indicarlo en este momento…o posteriormente exportar la capa temporal a una nueva capa.

Al pulsar “Aceptar” crea y añade la nueva capa a nuestra Vista. Si abrimos su “Tabla de atributos” veremos que tiene los campos de la capa “Locations”, más los campos de la capa “Political”:205_got

Ahora vamos a hacer un segundo geoproceso, esta vez sobre un grupo de elementos seleccionados de esta capa que acabamos de crear. Lo que queremos analizar es si la extensión de territorio de “Riverlands” tiene una lógica en relación a las localizaciones que alberga.

Lo primero que haremos será seleccionar de la capa “Enlace espacial” los elementos cuyo campo “name_1” sea igual a “Riverlands”. Si necesitáis ayuda con esta parte, repasad el post de “Herramientas de selección”. El resultado de la selección debe ser similar al de la siguiente imagen:206_got

Ahora volvemos a lanzar la “Caja de herramientas” y buscamos el geoproceso “Mínima envolvente convexa (Convex Hull)”:207_got

La ayuda nos dice que este geoproceso calcula la “Envolvente convexa”, o polígono convexo de menor área que envuelve a todos los elementos vectoriales de una “capa de entrada”. 209_got

Ejecutamos el geoproceso y nos saldrá una ventana como la siguiente:210_got

Seleccionamos como “Capa de entrada” la de “Enlace espacial” y nos fijamos que esté marcada la casilla de “Geom.seleccionadas (Capa entrada)”. De este modo el geoproceso se ejecutará unicamente sobre los elementos seleccionados. Al pulsar “Aceptar” se creará la nueva capa con el siguiente resultado donde vemos que el área es muy similar al territorio del Reino de “Riverlands”:211_got

Eso es todo por hoy. Una vez aprendido el procedimiento para lanzar geoprocesos…sólo os queda experimentar con ellos…Ya sólo quedan dos post para despedirnos de este curso.

gvSIG Team: Learning GIS with Game of Thrones (IX): Exporting View to image

OSGeo Planet - Tue, 2017-02-28 12:21

In gvSIG there are tools to design more or less complex maps, but there are many cases where we need to have an image of the frame of our View in gvSIG to be used in a presentation or document that we are writing.

Today we are going to see a very easy and useful tool when we want to have an immediate image from our View.

To run it we have to access to the “View/Export/Export view to image”. A new window will appear where we only have to indicate where we want to save the image file and its format (jpg, png, bmp or tiff).e080_got

An easy and useful tool, that is sometimes unknown by gvSIG users…
