gvSIG Team: gvSIG Desktop 2.4 testing phase is starting

OSGeo Planet - Mon, 2017-06-19 13:41

Good news for anybody who is waiting for the new gvSIG Desktop version. The builds publishing phase for testing has started already and the first tests are very positive.

Although we haven’t published any RC (Release Candidate) version yet, the most anxious users can download and test the different builds that will be released towards the final version (…when this post is released, the last build available is the number “2825”). These tests will be very useful to detect the errors that we haven’t detected. As you know you can communicate the errors through the mailing list or the project Redmine.

Where are we publishing the builds for testing? In:


If you access to the folder of a build, you will see that there are a lot of files published, and you will find the .run files for Linux and .exe for Windows in their different distributions (32 and 64 bits, and in the Linux distributions you will find them for Ubuntu 14.04 or lower, and higher).

In parallel to the stabilization of the version we will publish posts with the novelties of the gvSIG 2.4 version.

In addition, if you are interested in provide plugins to be included in this version, now it’s the moment to include them to be tested. If it’s your case you can contact us through the devel mailing lists or writing to the gvSIG Association mail address: info@gvsig.com

gvSIG Team: Learn GIS for free!

OSGeo Planet - Fri, 2017-06-16 12:52

We are going to start to publish a series of videos that form a complete GIS course, using gvSIG Desktop for that. Together with these videos we will publish the data necessary to follow the exercises.

The course is recommended to everyone who hasn’t worked on GIS and want to introduce to this type of technologies, as well as users that have knowledge about it already and want to increase it.

The course is made on gvSIG 2.1 version, and currently the last version is gvSIG 2.3.1 (we are working on the new 2.4 version already). We recommend you to use the last version published because it will have all the functionalities of the previous versions… and several improvements too.

It’s usual to have doubts when you follow the course. If you want to solve them you can use the users mailing list, available at this link: http://www.gvsig.com/en/community/mailing-lists

We are starting with three introductory videos:

1.1 GIS data types and formats

1.2 The Spatial Reference System

1.3 gvSIG preferences setup

Free and Open Source GIS Ramblings: Even more aggregations: QGIS point cluster renderer

OSGeo Planet - Tue, 2017-06-13 19:33

In the previous post, I demonstrated the aggregation support in QGIS expressions. Another popular request is to aggregate or cluster point features that are close to each other. If you have been following the QGIS project on mailing list or social media, you probably remember the successful cluster renderer crowd-funding campaign by North Road.

The point cluster renderer is implemented and can be tested in the current developer version. The renderer is highly customizable, for example, by styling the cluster symbol and adjusting the distance between points that should be in the same cluster:

Beyond this basic use case, the point cluster renderer can also be combined with categorized visualizations and clusters symbols can be colored in the corresponding category color and scaled by cluster size, as demoed in this video by the developer Nyall Dawson:

gvSIG Team: Disponible guía de taller de gvSIG Batoví: Sistemas de Información Geográfica como herramienta educativa

OSGeo Planet - Tue, 2017-06-13 08:38

El trabajo coordinado por Sergio Acosta para difundir el uso de los Sistemas de Información Geográfica en software libre en el ámbito educativo se merece todo el reconocimiento de la Comunidad gvSIG. No sólo están manteniendo y mejorando gvSIG Batoví, la distribución educativa de gvSIG Desktop, sino que además están realizando un continuo de actividades de capacitación para dar a conocer el potencial de gvSIG como herramienta educativa en la totalidad del territorio de Uruguay.

Dos talleres en Montevideo, uno de ellos con replica en la ciudad de Durazno (mediante video-conferencia), uno en Maldonado con réplica en la ciudad de Rivera y, finalmente, otro en Colonia del Sacramento con réplica en Paysandú.

Pero hablando de conocimiento libre, lo importante es que todo esto es totalmente replicable en cualquier parte del mundo. Y para ello no sólo os podéis basar en la experiencia de Uruguay, también podéis utilizar el material que están generando.

Así, la guía utilizada en estos talleres se ha liberado con acceso público, y podéis descargarla aquí:


La mayor parte de esta guía puede seguirse con un gvSIG Destkop “estándar”, pero sin duda para aquellos que estén interesados en su aplicación al mundo educativo lo mejor es descargar e instalar gvSIG Batoví (en el vínculo podréis acceder a la versión para Ubuntu -en base a gvSIG 2.2- y desde Uruguay nos indican que pronto también estará para Windows -basada en la versión 2.3.1 de gvSIG-).

El taller parte de una pequeña introducción, luego explica cómo buscar datos espaciales y luego desplegarlos en el Batoví, un recorrido por las herramientas de navegación, selección y consulta, cómo combinar información (geográfica) de diferentes formatos (gráfica y en planilla), cómo exportar a otros formatos, cómo crear Información Geográfica, algunos geoprocesos como reproyección, recorte y finalmente la creación de un mapa de calor. El taller concluye explicando cómo armar una Vista y compartirla, así como describiendo algunos pasos básicos para crear un mapa y compartirlo.

Ni un estudiante sin su SIG libre…

gvSIG Team: Acceso a servicios de mapas (Google Maps, Bing Maps, OpenStreetMap, OGC) con gvSIG Desktop

OSGeo Planet - Tue, 2017-06-13 07:47

Hoy día podemos trabajar en nuestro SIG libre con cartografías muy completas, varias de ellas a escala planetaria, sin tener ni un fichero en nuestro ordenador. Gracias a servicios de mapas estándar -destacando en WMS y el WMTS- y no estándar (pero muy populares) como OpenStreetMap, Google Maps o Bing Maps el disponer de cartografía base que cruzar con nuestras datos ha dejado de ser un problema.

Que estos datos sean externos no impide que podamos aplicar sobre ellos ciertos tipos de herramientas, del mismo modo que haríamos si trabajáramos con datos en local.

Aprender a trabajar con este tipo de datos es tan sencillo cómo dedicar unos minutos a ver el nuevo webinar publicado en el Máster de Valoración, Catastro y Sistemas de Información Territorial. Y todo ello en vuestro SIG favorito.

gvSIG Team: Learning GIS with Game of Thrones (XII). Graphic editing tools

OSGeo Planet - Fri, 2017-06-09 19:00

As a complement of a previous post in which we talked about the table edition tools, today we will show you the tools for graphic edition. These tools will allow you to create and edit vector data. We must keep in mind that certain data formats are read-only and do not allow editing.

In order to add or modify elements of a layer, it must be necessary that the layer is activated and in editing mode. Depending on the type of layer to be edited (points, lines and / or polygons ), some tools will be available.

These tools are available from the “Layer” menu in the “Remove”, “Insert” and “Modify” submenus, from the “Edit” menu and from the corresponding button bars.

We remind you that this is a basic introduction course to GIS. Anyhow, in order to know in detail all editing tools we strongly recommend you to check out the gvSIG Desktop user manual:

After this introduction, we are going to do a practical exercise using information from the famous TV series Game of Thrones.

This exercise consists of creating a new layer in which we will add the routes or trips that follow each of the protagonists of the saga. In this case, we will draw Greyjoy brothers´ travel from Pyke to Meereen, passing through Volantis.

First of all, we have to create a new layer (in shapefile format). This tool is available in the menu, where we select the order “Layer/New Layer”.

An assistant will pop up. It will show the steps needed for creating a new layer :

We must select “Create a new Shape layer” and then, click the“Next” button.

In the next step, we will create an “Output File”; we have to indicate the name and the path route where the new layer will be saved (for example we can call it “Routes”). Once defined, we click the “Next” button.

It is possible to define the geometry type of layer: Point, Curve, Surface or Multipoint. As we want to represent a route, we have to draw a layer consisting of lines. Therefore we select in the interface the “Curve” type of geometry.

It is possible to add attribute fields to the new layer using the “Add Field” button. We want to add a “Name” attribute, therefore we select “String” type (text string). It will serve us to identify by name each of the routes.

In this step we can add any kind of field needed to improve the classification. When the attribute table is defined, then click “Next”.

Finally we select the option “add the new layer to the view”. In order to end, press the “Finish” button. We have already the new, empty layer, with no elements included in. In order to continue the exercise we have to start filling with content.

To make easier the drawing of the route, (check out our previous post about in this page) “Labelling”,we will label the “Locations” layer, which will allow us to identify easily the route through the places we want to: Pyke, Volantis And Meereen. You can also use the “selection tools” or the “locator by attribute” to identify these locations.
First of all we are going to turn our layer in “edit mode”. When activated, there are two possible ways to do it: by selecting “Menu/layer/Start editing” o by clicking in the context menu of the Table of contents (TOC).

When in editing mode, the name of the layer turns red:106_got

You will also see the new toolbars that have appeared in the interface. These will allow you to draw new elements as well as edit existing ones:107_got

The last change of interface is located at the bottom of the View, where we can expand or contract a command bar:108_got

Before starting the drawing of the route it is interesting to keep in mind two basic supporting tools to drawing. We can change the display scale by using the mouse wheel, moving forward and back. When we press the wheel, we can scroll through the map.

To start drawing the route, select the “Draw polyline” tool::109_got

We are located near Pyke and we click with the mouse, in order to have the first point of our route. Then we will use the mouse wheel to navigate through the map eand then add intermediate points until arriving first in Volantis, and later in Meereen. Once the last point is drawn, we click in the right mouse button and in the context menu we select the option “Finish”.
As previously shown at the “Editing Tables” post, now we could edit its attributes and write, e.g., “Greyjoy brothers” in order to identify this travel.
