gvSIG Team: Llamamiento a la Comunidad gvSIG: traducciones de gvSIG Desktop 2.4

OSGeo Planet - Mon, 2017-06-26 13:26

La nueva versión 2.4 de gvSIG Desktop ya se encuentra en fase de estabilización, y en paralelo se están actualizando las traducciones de la interfaz de cara a tener la versión final disponible en el mayor número de idiomas posible.

Actualmente gvSIG se encuentra traducido a más de 25 idiomas, gracias a la participación de la Comunidad.

Existen dos formas de colaboración, bien actualizar cualquiera de los idiomas ya existentes en versiones anteriores, o bien traducir a algún idioma en el que no se encuentre traducido gvSIG actualmente.

Si estáis interesad@s en traducir la interfaz de gvSIG podéis poneros en contacto con el proyecto [info@gvsig.com], y os indicaremos las instrucciones.

Las traducciones que no estén finalizadas en el momento de la publicación de la versión final se publicarán como paquetes que podrán ser cargados directamente desde el Administrador de complementos de gvSIG.

¡Esperamos vuestra colaboración!

gvSIG Team: Calling for gvSIG Community: gvSIG Desktop 2.4 translations

OSGeo Planet - Mon, 2017-06-26 13:24

The new gvSIG 2.4 version is starting the stabilization phase, and in parallel the translations of the interface are being updated in order to have the final version with as many languages as possible.

Currently gvSIG is translated to more than 25 languages, thank to the participation of the Community.

There are two ways of collaboration: updating any of the existing languages, as well as translating gvSIG interface to a new language in which gvSIG is not translated currently.

If you are interested in translating gvSIG interface you can contact the gvSIG Project [info@gvsig.com] and we would send the instructions to do it.

Translations that aren’t finished when the final version is released will be published as a package to be loaded from the gvSIG Add-ons manager.

We expect your collaboration!

Jackie Ng: Announcing: mapguide-react-layout 0.9.1

OSGeo Planet - Mon, 2017-06-26 12:44
This is a small bug fix release that brings updates to key libraries we use:

And includes the following fixes:This release also has one small enhancement, the viewer now supports a mount option for specifying initial visibility of template elements (Legend, Task Pane, Selection Panel). Currently this will have the most impact when used with the Aqua and Sidebar viewer templates.
For other viewer templates, this new feature won't have much effect yet. For example, take the Slate template.

The very design of this template means that if you wanted all Legend/TaskPane/SelectionPanel to be hidden initially, you just cannot do it. Because they all reside in an accordion, one of these elements has to be visible. The original Fusion templates (at least slate from my memory) could conceivably have Legend/TaskPane/SelectionPanel all hidden because its sidebar was collapsible. That is not the case in this iteration of Slate (and the other ported templates with a sidebar). Having collapsible sidebars in these viewer templates will be a problem a future release will be fixing.
Finally, one thing that was actually possible in the 0.9 release, but I didn't really mention because I wanted to make sure this feature was working before actually announcing it is that Script Commands which is the InvokeScript replacement in mapguide-react-layout can be used with the standard viewer bundle. You no longer need to exclusively use the npm module to have support for Script Commands.
You can see an example of script command registration using the standard viewer bundle here.

Nathan Woodrow: QGIS WHY U NO PRINT DEBUG INFO

OSGeo Planet - Mon, 2017-06-26 09:17

One of those days today where I burnt more time then I should on something that I din’t know about and spent way to much time searching for the wrong thing.

On a new install of Fedora I couldn’t get my QGIS to output any debug messages, even on my dev build running in the terminal, Qt Creator, or VS Code. Super frustraining to say the least.

Turns out the logging, at least on Fedora for Qt5, is disabled by default. You need to enable it by editing ~/.config/QtProject/qtlogging.ini and adding the following:

[Rules]
default.debug=true

The more you know!

gvSIG Team: Camino a gvSIG 2.4: Cambiando el aspecto de gvSIG. Nuevo juego de iconos

OSGeo Planet - Fri, 2017-06-23 12:29

gvSIG utiliza el mismo juego de iconos desde hace ya un buen número de años, por lo que decidimos dar la posibilidad a los usuarios de poder cambiar los temas o juegos de iconos con facilidad. Para ello hemos generado un plugin del que hablaremos en otro post. En este queremos mostraros el excelente juego de iconos que ha creado Mario Fèvre de la empresa TreCC S.A. y las instrucciones para que podáis probarlo en gvSIG Desktop 2.4.

En paralelo a la creación de los paquetes, se ha generado una completa guía de estilo que de momento podéis consultar aquí.

Se han generado dos paquetes, con el juego de iconos a 16×16 y a 22×22. Este segundo juego de iconos cubre una de las demandas de parte de la comunidad gvSIG, que solicitaba poder trabajar con botones a mayor tamaño.

Los paquetes se pueden descargar en los siguientes enlaces:

Una vez descargados los podéis instalar por el ‘Administrador de paquetes’, de momento por la opción ‘Desde archivo’ (en la versión final ya estarán disponibles en el repositorio oficial). Para marcarlo como paquete instalable buscar el denominado ‘TreCC-icon-set’…22×22 o 16×16 según corresponda.

Una vez instalado tenéis que reiniciar gvSIG Desktop. Todo seguirá igual, falta un siguiente paso para indicar a la aplicación que queremos utilizar uno de los nuevos juegos de iconos.

Vamos a ‘Preferencias’ y seleccionamos el juego de iconos a utilizar en el apartado ‘General/Juego de iconos’, tal y como se muestra en la imagen:

Una vez realizada la operación reiniciamos gvSIG Desktop y ya podemos disfrutar del nuevo aspecto de nuestro SIG favorito. Por cierto, en los últimos builds no existe la posibilidad de volver al juego de iconos ‘clásico’ (recordar que estamos en fase de testeo y estabilización), aunque en futuros builds por supuesto estará contemplada esta opción.

Os dejo con un pequeño vídeo que recorre el nuevo aspecto que adopta gvSIG Desktop.

Por último comentar que gvSIG Desktop 2.4 saldrá con el juego de iconos ‘clásico’, ya que no sólo es al que están acostumbrados la mayoría de usuarios sino que también es al que se refiere toda la documentación existente, pero los nuevos iconos estarán disponibles en la aplicación para poder utilizarlos. Y ya, en futuras versiones, nos plantearemos que gvSIG pueda salir de base con un nuevo juego de iconos, teniendo el ‘clásico’ disponible para su uso.

Paul Ramsey: The Open Source Support Company Trap

OSGeo Planet - Thu, 2017-06-22 16:00

Matt Asay asks a question about big data vendors, who are from a business model point-of-view mostly “open source support” companies: HortonWorks as a pure-play and others as open-core and enhanced-oss models.

Is the problem that orgs roll-their-own Spark/etc. (self-support on OSS)? Or maybe most orgs simply aren't doing much (yet) w/ big data? https://t.co/9RGZyEUaV4

— Matt Asay (@mjasay) June 22, 2017

My experience has been that open source support companies fall into a market trap. They are supporting good projects, that are popular and widely deployed. It seems like a good place, but the market keeps constantly screwing them.

TL;DR

Potential open source support customers are either:

  • Small enough to need your expert support, but too small and cheap to supply company-supporting levels of revenue; or,
  • Large enough to figure it out for themselves, so either take a quick hit of consulting up front or just ignore you and self-support from the start.
Small Customers Suck

Small customers lack the technical wherewithal to use the product unassisted, so they need the support, but they are both highly price sensitive while also being a large drain on support hours (because they really need a lot of help).

You can drop your prices to try and load up a lot of these (“how do we do it? volume!”) but there are rarely enough fish in the pool to actually run the size of business you need to achieve sustainability.

How large? Large enough that the recurring revenue is enough to support sales, marketing, cost of sales, and a handful of core developers who aren’t tied to support contracts. Not huge, but well beyond the scale of a dev-and-friend-in-basement.

If you do drop your prices to try and bring in the small customers you immediately run into a problem with big customers, who will want big customer questions answered at your small customer price point.

Big Customers Suck, Then Leave

Big customers are frequently drawn to the scaling aspects of open source: deploy 1 instance, deploy 100, the capital cost remains the same.

In theory, there should be room in there for a “one throat to choak” support opportunity for big customers with big deployments, and with competent sales work up front, a good support deal will monetize at least some of the complexity inherent in a large deployment.

In practice, instead of being long term recurring revenue, the big customers end up being short term consulting gigs. A deal is signed, the customer’s team learns the ropes, with lots of support hours from top level devs on your team, and the deployment goes live. Then things settle down and there is a quick scaling back of support payments: year one is great, year two is OK, year three they’re backing away, year four they’re gone.

While there is room to grow a business on this terrain, particularly if the customers are Really Really Big, the constant fade-out of recurring revenue means that the business model is that of a high-end consultancy, not a recurring-revenue support company.

gvSIG Team: Tutorial para aprender a crear capas de eventos en gvSIG Desktop

OSGeo Planet - Thu, 2017-06-22 08:06

Hoy os presentamos un vídeo-tutorial que nos enseña cómo crear una capa de eventos, una de las tareas que antes o después necesitaremos hacer con nuestro SIG. Una funcionalidad que complementa a la carga directa como capa de archivos xls y csv que está disponible en las últimas versiones de gvSIG Desktop.

¿Qué es un evento? En terminología SIG se suele denominar evento a cualquier fenómeno puntual susceptible de ser georreferenciado. Por tanto, una capa de eventos será una capa de puntos que tiene su origen en una Tabla que contiene entre sus atributos las coordenadas que permiten su georreferenciación.

GeoServer Team: GeoServer 2.10.4 Released

OSGeo Planet - Wed, 2017-06-21 23:40

We are pleased to announce the release of GeoServer 2.10.4. Downloads are available (zipwardmg and exe) along with documentation and extensions.

This is a maintenance release of GeoServer suitable for production systems. Maintenance releases are focused on bug fixes and stability, rather than new features. This release is made in conjunction with GeoTools 16.4 and GeoWebCache 1.10.3.

This release is made by Torben Barsballe and Kevin Smith from the Boundless team. Special thanks to Nick Stires from Boundless and the Frank Warmerdam from OSGeo for their help setting up the new build.geoserver.org server used for this release. We would like to thank these volunteers and everyone who contributed features, fixes and time during the release process.

Security Considerations

The 2.10.3 release addressed three security vulnerabilities. Details of these vulnerabilities were not included in the 2.10.3 blog post to provide time for the fixes to be included in 2.11.1, and have been replicated here:

  • Added a configurable delay during login, to mitigate a brute force attack.
  • Added a configurable parameter to control clickjacking attacks against the GeoServer UI.
  • Added an additional parameter for locking down password autocomplete in the GeoServer UI

Thanks to Andrea Aime and Devon Tucker for providing fixes to these issues.

If you wish to report a security vulnerability, please visit our website for instructions on responsible reporting.

New Features and Improvements
  • Add rest endpoint for geofence admin rules
  • Add REST endpoint for a user to change their password
  • Allow disabling usage of SLD and SLD_BODY in WMS requests (also for virtual services)
Bug Fixes
  • Native JAI installation instructions report incorrect information about the installers
  • Downloading zip file using /rest/workspaces/<ws>/datastores/<ds>/file.shp doesn’t work after GeoServer reload
  • Virtual services do not play nice with GML 3 encoding
  • Namespace filtering on capabilties returns all layer groups (including the ones in other workspaces)
  • Cascaded WMS does not encrypt configuration password
  • Reloading GeoServer re-enables all disabled WMTS services
  • Slow WFS GetFeature when using a 3D bbox POST request
  • WMS cascading fails with NPE when advanced projection handling gets disabled

Andrea Antonello: Geopaparazzi 5.4.0 is out

OSGeo Planet - Wed, 2017-06-21 13:11
We just released Geopaparazzi 5.4.0 into the wild!

It all started with a bug fix to have a 5.3.2 that would be able to read the latest mapsforge maps. For some unknown reason the backward compatibility had been lost and geopaparazzi was no longer able to visualize newer mapsforge maps. Being the most important map used, that had to be fixed.

Then we noticed that also GPS import was broken. In fact the new plugin system had a bug. That also had to be fixed.

Then we fixed some smaller usability issues that had been reported, but this also was ok for a 5.3.2 bugfix release.

What made us decide to go for a 5.4.0, was a fantastic project we are doing with other members of the gvSIG Association for INEGI. INEGI is the National Institute of Statistics and Geography of Mexico and recently we won a tender to supply a whole GIS stack for Desktop-Server-Mobile.

At HydroloGIS we are obviously taking care of the mobile part and it is thrilling to know that INEGI invested in Geopaparazzi/gvSIG Mobile and that hundreds of technicians will use it to do their digital field surveys.

That project already brought in the previous release an important change which is the plugin system.

Recently it also added to geopaparazzi two important features:

1) support for unique values map theming in spatialite databases

Geopaparazzi now supports in readonly mode unique value styled spatialite layers.

We are used to a simple style in geopaparazzi:






Now you can do things like these...

Polygons:


Lines:


Points:


Looks quite nifty :-)

But now the problem... how do we make such a styled database?

We created a tool inside the JGrasstools Spatialtoobox, which means it will also get to gvSIG. Right now there are compatibility issues between the spatialite drivers of JGrasstools and gvSIG. We will probably get there for the 2.4.0 release.

In the meanwhile people interested can pick the standalone version of the JGrasstools' Spatialtoolbox, which can be downloaded here.

Just run the script jgt-spatialtoolbox.sh and look for the right module:



Now pay attention. This will import a folder of shapefiles into a newly created (or existing) spatialite database. If the shapefile has a style defined in an SLD file, then that will be used. So use your favorite SLD editor and create a unique values theme, and it will be inserted in the new database, geopaparazzi ready!

2) pdf export

The second interesting feature is the PDF export of form based notes.

For those users that couldn't care less of GIS and complex stuff, but only want to have a nice ordered list of the surveyed data, the PROJECT FORMS TO PDF button is the right choice:


This will export the content of the form based notes to PDF, trying to group the information nicely into tables, adding any image contained in the note.
Just to have an idea, this is how 2 random pages would look like:


That's it, huge thanks to INEGI for pushing this project and making geopaparazzi better!!

gvSIG Team: Camino a gvSIG 2.4: Biblioteca de símbolos de Planificación Urbanística y Territorial de la Comunitat Valenciana

OSGeo Planet - Wed, 2017-06-21 11:47

Aunque está biblioteca de símbolos será útil principalmente a los usuarios de gvSIG de la Comunitat Valenciana es un claro ejemplo de bibliotecas similares que podrían realizarse para facilitar el trabajo de usuarios que se encuentran con una necesidad similar: trabajar con una simbología homogeneizada para un determinado caso de uso.

El Decreto 74/2016, de 10 de junio, del Consell, aprueba el Reglamento por el que se determina la referenciación cartográfica y los formatos de presentación de los instrumentos de planificación urbanística y territorial de la Comunitat Valenciana.

Este Decreto tiene entre otros objetivos el homogeneizar la simbología de la información urbanística, indicándose en el ‘Anexo III’ la estructura de capas, códigos de color de relleno, tipos de línea y símbolos.

Como sabéis en gvSIG Desktop es extremadamente fácil generar nuevas bibliotecas de símbolos, que además podemos convertir en paquetes que cualquier usuario pueda instalarse desde el ‘Administrador de complementos’.

Para facilitar el trabajo requerido por el citado Reglamento a los Ayuntamientos de la Comunitat Valenciana se ha generado esta nueva biblioteca que aunque estará disponible en el repositorio de plugins del próximo gvSIG Desktop 2.4, ya puede descargarse, instalarse y utilizarse.

Podéis descargar el paquete aquí.

En el siguiente vídeo os mostramos cómo instalarlo:

Paul Ramsey: CURL Options and Availability Version

OSGeo Planet - Tue, 2017-06-20 16:00

I’ve been adding support for arbitrary CURL options to http-pgsql, and have bumped up against the classic problem with linking external libraries: different functionality in different versions.

CURL has a huge collection of options, and different versions have different support, but for any given options, what versions support it? This turns out to be a fiddly question to answer in general. Each option has availability in the documentation page, but finding availability for every option is a pain.

So, I’ve scraped the documentation and put the answers in a CSV file, along with the hex-encoded version number that CURL exposes in #define LIBCURL_VERSION_NUM.

If you need to re-run the table as new versions come out, the Python script is also in the Gist.
