gvSIG Team: Aprendiendo SIG con Juego de Tronos (XIV): Mapas

OSGeo Planet - Mon, 2017-03-06 21:28

En este penúltimo post del curso para aprender la bases de los Sistemas de Información Geográfica mediante ejercicios prácticos con datos de Juego de Tronos vamos a trabajar con el documento “Mapa”.

Un documento Mapa es un conjunto de elementos de diseño de un mapa o plano, organizados en una página virtual y cuyo objetivo es su salida gráfica (impresión o exportación a PDF). Lo que se ve en el diseño es lo que se obtiene al imprimir o exportar el mapa al mismo tamaño de página definido. En un Mapa se pueden insertar dos tipos de elementos: Elementos cartográficos y de diseño.

En nuestro caso vamos a crear un mapa con la ruta seguida por los hermanos Greyjoy y dibujada en el post sobre “Edición gráfica”.

Una vez tenemos abierto nuestro proyecto en gvSIG, lo primero que haremos es ir a la ventana de “Gestor de proyecto”. Una forma rápida de hacerlo es mediante el menú “Mostrar/Gestor de proyecto”. Seleccionamos el tipo de documento “Mapa” y pulsamos el botón de nuevo. Se nos abrirá una nueva ventana donde definiremos la características de la página de Mapa.

En nuestro caso seleccionaremos un “Tamaño de página” de “A4”, con “Orientación” “Horizontal” y le indicaremos que utilice la Vista donde tenemos nuestras capas cargadas en lugar de “Crear nueva Vista”. Si tenéis más de una Vista en vuestro proyecto, aparecerá un listado con todas ellas.

Veréis que crea un nuevo mapa, en el que se ha insertado la Vista indicada y que ocupa toda la superficie de la página:

Pulsando sobre los “cuadrados negros” que aparecen en las esquinas y puntos medios del rectángulo que define la extensión de la Vista podemos cambiar su tamaño. De este modo vamos definiendo nuestro diseño del mapa. Haciendo clic sobre el elemento Vista insertado y arrastrando podemos desplazarlo. En nuestro caso redimensionamos la Vista insertada y la desplazamos, pasando a continuación a añadir otros elementos cartográficos.

La mayoría de los elementos cartográficos están íntimamente ligados a un documento Vista, de modo que al realizar cambios en la Vista, pueden verse reflejados en el mapa (cambios de zoom, desplazamientos, modificación de leyendas, organización de capas, etc.). Estas herramientas están disponibles desde el menú “Mapa/Insertar“ y en la barra de botones correspondiente.

Vamos a comenzar por insertar la leyenda. Esta herramienta está disponible desde el menú “Mapa/Insertar/Leyenda“ o con su botón:

La leyenda siempre se asocia con una Vista insertada en el Mapa y permite representar la simbología de las distintas capas de esa Vista. Una vez seleccionada la herramienta, se indicará el primer extremo del rectángulo que define el espacio a ocupar por la leyenda haciendo clic sobre el área de Mapa en el lugar deseado, y arrastrando hasta soltar en el extremo opuesto. Se mostrará un cuadro de diálogo en el que puede definir las propiedades gráficas de la leyenda insertada:

En esta ventana podemos marcar que capas (su simbología) queremos que aparezca en la leyenda.

A continuación pasamos a insertar un símbolo de Norte. Esta herramienta está disponible desde el menú “Mapa/Insertar/Norte“ y en su botón correspondiente:

Una vez seleccionada la herramienta, se indicará el primer extremo del rectángulo que define el espacio a ocupar por el símbolo de norte haciendo clic sobre el área de Mapa en el lugar deseado, y arrastrando hasta soltar en el extremo opuesto. Se mostrará un cuadro de diálogo en el que puede definir las propiedades gráficas del norte insertado:

Y nuestro Mapa tendrá el siguiente aspecto:

Para finalizar insertaremos un título con la herramienta de “Insertar texto” (en el menú Mapa/Insertar/Texto o en su botón correspondiente). El funcionamiento es similar al de los otros elementos, y en este caso lo que indicaremos es el texto que queremos que aparezca: “Greyjoy Brothers”.

A partir de aquí y por no alargar demasiado el post os encomendamos a que reviséis la documentación relacionada con el documento Mapa y que vayáis probando a insertar escalas gráficas, cajetines, etc. así como a probar las herramientas de ayuda al dibujo…con práctica os pueden quedar mapas realmente bien diseñados.

Una vez tengáis vuestro mapa acabado podéis exportarlo a PDF con el botón:

Ya podéis enviar vuestro archivo PDF a todos vuestros contactos.

Como suelen decir, la práctica hace al maestro…así que ya sabéis.

Queda un post para despedir el curso…no os lo perdáis.

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

senzanome

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.

Paulo van Breugel: Exporting rasters to Mbtiles using GDAL

OSGeo Planet - Sun, 2017-03-05 23:24
Web maps are generally made up of many small, square images called tiles, which are placed side by side in order to create the illusion of a very large seamless image [for a good explanation, see here]. Tiled based maps can be made up of many tiles. Loading all those tiles would be inefficient and … Continue reading Exporting rasters to Mbtiles using GDAL

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.

SCP 5.99 running in QGIS 2.99
