gvSIG Team: New plugin for gvSIG 2.4: Statistics Viewer

Planet OSGeo feeds - Thu, 03/01/2018 - 18:45

Starting as a final project for a Master in Visual Analytics and Big Data, a new  plugin for gvSIG 2.4 has been developed. Its mainly porpouse is to search for new ways to analyze and visualize data for extract knowledge from it.

This tool is denominated “Statistics Viewer”. It has a group of tools.

In the menu you will find all the processes available

They are divided in 3 categories:

  • Statistical
  • Clusterization
  • Utility: for download future new processes or test the app.

The statistical process are oriented to error detection in the alphanumeric values. This errors are  difficult to find if there are no specified tools for it. Also, they will help us to learn about the meaning of our data.

For example, in the last picture, we can see a linear regression from two fields of a vector layer. Each point makes reference to a different feature. Also, you can click the point and automatically it will be selected in the layer loaded in the gvSIG View.

Other processes to help us to find relation between fields are: Pearson’s correlation and the covariance matrix.

Another important processes are clustering processes. They will allow us to group features. Our analysis will not be just limited to the spatial component.

The next image shows another cluster creation using two fields.

Also, there are utility function in the plugin. For example, with the auto zoom option activated, the process will be executed each time we change the zoom in the view. This is usefull to explore dynamically our data. The output in the graph its related with all the points that we see in the gvSIG View.

As we change the View, the process is auto executed and the output changes.

This plugin is available for testing in gvSIG 2.4 and  it can be download it from Tools – Addons Manager – Online repository and it will appear as Statistics Viewer.

Once it’s installed, gvSIG need to be reopened. Then it will appear a new icon in the tool as it shows here.

To use it: It need to be opened after a View is created. Select the desired algorithm and fill all the parameters manualy. If a layer is required, it will need the name of the layer as it appears in the Table of Contents in the gvSIG View.

This tools is in its first stages and is currently in development, so the options are limited. It has been realized with the Scripting Module and using Jython as language. Also it uses other libraries, Jfreechart for graphics representations, and Apache Commons Math for cluster analysis.

Code can be found in Github. Any feedback will be appreciated.

gvSIG Team: GIS applied to Municipality Management: Module 16.1 ‘gvSIG Online (Publishing cartography, advanced editing…)’’

Planet OSGeo feeds - Thu, 03/01/2018 - 10:59

The first video of sixteenth module is now available, where we will see how to work with gvSIG Online.

gvSIG Online is an integral solution in free software for managing the spatial information of an organization following the Spatial Data Infrastructures (SDI) model.

With gvSIG Online a city council can organize its geographic information in the most efficient way, having a powerful tool, both to generate map or geoportal viewers easily and to manage the spatial database of the organization, also betting on free technologies to guarantee their technological independence (apart from saving in implementation costs considerably).

An SDI allows to organize all the geographic information, facilitating its location and access in real time, avoiding duplication of information, solving the accessing problem to updated information and allowing interoperability with geographic information both internally and from other organizations.

In general, gvSIG Online users will have web applications or mobile applications (optionally desktop ones too) to access and interact with the geographic information of the organization, using layers from standard services such as the map service (WMS) and tiled maps (WMTS), the feature service (WFS) and transactional feature service (WFS-T) and the geoprocessing service (WPS). Finally, all the information will be centralized in a spatial database.

In this module you won’t be able to perform the exercise directly, because an implementation of the platform is necessary, but you can see everything that can be done with gvSIG Online.

If you are interested in implementing gvSIG Online in your city council, or in any other organization, you can contact us, writing to this mail address: info@gvsig.com, where we will inform you about it.

Here you have the first videotutorial of this module:

gvSIG Team: Nueva extensión para gvSIG 2.4: Visor de Estadísticas (Statistics Viewer)

Planet OSGeo feeds - Mon, 02/26/2018 - 15:10

A raíz de un proyecto final de Master sobre Visualización y Análisis de Datos Masivos (Big Data) y junto a la Asociación gvSIG, se ha realizado una extensión para gvSIG 2.4 que busca la introducción de nuevas herramientas que favorezcan y faciliten el análisis y la extracción de conocimiento de los datos que tenemos.

Este herramienta desarrollada se denomina “Statistics Viewer” o “Visor de estadísticas”. En ella se incluyen diferentes herramientas de análisis y de visualización.

Aspecto principal de la herramienta

En el menú desplegable se pueden encontrar los diferentes procesos que dispone la herramienta:

Los procesos principalmente se dividen en 3 categorías:

  • Estadísticos
  • Clusterización
  • Utilidades: actualmente solo compuesto por el de Descarga de procesos, que nos permitiría incorporar nuevos procesos directamente con un link de descarga.

Los procesos estadísticos están orientados a la detección de errores en los campos alfanuméricos que de otra forma serían difíciles de localizar. A su vez, estos procesos nos ayudarán a extraer conocimiento de las diferentes columnas de datos en las capas cargadas.

Por ejemplo, en la imagen anterior, podríamos ver la distribución en forma de una regresión lineal de los datos de una capa según dos campos. Los puntos representados hacen referencia a diferentes entidades. Además, estos puntos son clickables, por lo que al presionar uno de ellos se realizará la selección de su correspondiente en la capa de gvSIG cargada en la Vista.

Otros procesos de exploración son los de Correlación de Pearsons y Covarianza. Estos procesos ayudan a buscar la relación entre diferentes campos de las entidades.

Otros procesos incluidos son los procesos de clusterización. Estos procesos nos permiten agrupar las entidades según los valores que tienen en un campo, y no limitándonos solo a la componente espacial.

En la siguiente imagen se puede ver otro proceso de clusterización numérica.

También dispone de otras funcionalidades como la de “Zoom auto process”. Esta funcionalidad permite al algoritmo ejecutarse cada vez que modificamos zoom en la Vista de gvSIG. Esto permite por ejemplo, tal y como se muestra en la siguiente imagen, explorar un perfil de manera dinámica, por cada zoom se actualizará la gráfica mostrando solo los valores visibles en  la Vista en ese momento. Esto permite explorar nuestros datos de una manera más efectiva.

Y aquí después de modificar el zoom:

La extensión está disponible para descarga desde el Administrador de Complementos – Instalación Online:

Una vez instalada, deberás reiniciar gvSIG y al volverlo a iniciar ya verás como aparece el icono que se muestra en la primera imagen de este artículo.

Para utilizarlo deberás ejecutarlo cuando tengas una Vista abierta con las capas cargadas. Seleccionar el algoritmo deseado, y rellernalo con los parámetros que nos pide. Si pide el nombre de una capa, deberás escribir el nombre de la capa tal y como aparece en la Tabla de Contenidos de la Vista.

Es una herramienta que se encuentra en desarrollo, por lo que las opciones son limitadas. Los campos se deben de introducir manualmente tanto de capas como de campos. Ha sido realizada con el Módulo de Scripting, desarrollada sobre Jython, y utilizando diferentes librerías como Jfreechart para la creación de gráficos, o la librería Apache Commons Math para la utilización de los diferentes algoritmos explicados.

Esperamos que sea de utilidad. Cualquier feedback será bien recibido. El código de la aplicación se puede encontrar en Github.

gvSIG Team: GIS applied to Municipality Management: Module 15 ‘gvSIG 3D’

Planet OSGeo feeds - Mon, 02/26/2018 - 12:23

The video of the fifteenth module is now available, in which we will see the main functionalities of the 3D extension in gvSIG, based on NASA WorldWind application.

In this module the user will learn how to create a 3D View from a 2D one. The 3D Views that we can create are flat views, when we work in local areas, and spherical views, when we want to see them on the terrestrial sphere.

In the 3D Views we can visualize the digital elevation models, and we can overlap any other layer on them, such as an orthophoto.

On the other hand, if we have a vector layer with building footprints, and a field in which we have the number of floors or the height of the building, we can apply extrusion, so that we can see the polygons vertically as if it were the building, and it helps us to visualize the structure of the city in an easy way.

Finally, another functionality available in the 3D module is the tool to create animations. It’s made by capturing screens in certain frames, and then a video is created, interpolating between the different frames automatically. It’s very useful for a presentation, when we want to show the different areas of our city in detail.

The cartography to follow this video can be downloaded from this link.

Here you have the videotutorial of this new module:

Planet OSGeo feeds - Mon, 02/26/2018 - 08:46

We are very pleased to convey the announcement of the  QGIS 3.0 major release called “Girona”.

The whole QGIS community has been working hard on so many changes for the last two years. This version is a major step in the evolution of QGIS. There are a lot of features, and many changes to the underlying code.

At Oslandia, we pushed some great new features, a lot of bugfixes and made our best to help in synchronizing efforts with the community.

Please note that the installers and binaries are still currently being built for all platforms, Ubuntu is already here, OSGEO4W and Mac packages are still building.

The development versions for the ChangeLog and documentation are being worked on so please start testing that brand new version and let’s make it stronger and stronger together. The more contributors, the better!

While QGIS 3.0 represent a lot of work, note that this version is not a “Long Term Release” and may not be as stable as required for production work.

We would like to thank all the contributors who helped making QGIS 3 a reality.

Oslandia contributors should acknowledged too : Hugo Mercier, Paul Blottière, Régis Haubourg, Vincent Mora and Loïc Bartoletti.

We also want to thank some those who supported directly important features of QGIS3 :

gvSIG Team: Mapas para visualizar cómo perciben los ciudadanos la democracia

Planet OSGeo feeds - Fri, 02/23/2018 - 19:33

En Sociología el uso de los Sistemas de Información Geográfica no es precisamente frecuente, pese a constituirse como una herramienta fundamental para analizar la información desde el punto de vista de las relaciones espaciales. La hasta hace poco falta de opciones de disponer de software SIG, limitadas a costosas licencias de unas pocas transnacionales no interesadas en aquellos sectores que no aumentan su cuenta de resultados, es uno de los principales motivos.

Desde la aparición de proyectos de software libre como gvSIG, estamos viendo como son cada vez más los estudios que desde el campo de la sociología comienzan a hacer uso de este tipo de herramientas. Por eso mismo creo que vale la pena dar eco a estas iniciativas y estudios. Y de ahí este post…

En octubre del pasado año el Pew Research Center realizó una encuesta en 38 países que buscaba determinar cómo se ve a la democracia, un gobierno militar y otros sistemas políticos alrededor del mundo.

@pablinte ha publicado un hilo en Twitter en el que partiendo de los resultados de esa encuesta aporta una visualización complementaria y realmente interesante mediante el uso de gvSIG Desktop, con el que ha realizado una serie de mapas que nos permitimos compartir en este post.

El informe en el cual se basan estos mapas es del 2017 lo podéis encontrar aquí. La metodología y el diseño muestral de la encuesta aquí.

QGIS Blog: QGIS 3.0 Girona is released!

Planet OSGeo feeds - Fri, 02/23/2018 - 19:28

We are pleased to announce the release of QGIS 3.0 ‘Girona’. The city of Girona was the location of our 15th developer meeting.

This is the first release in the 3.x series. It comes with tons of new features (see our visual changelog) and under-the-hood updates. As such, we do not expect it to be as reliable as the 2.18 LTR just yet.

From now on, 2.18 is the only Long Term Release (LTR) and 2.14 is retired.

Once the release is done, our packagers will start preparing packages for different operating systems. We’ll keep you updated when different packages and installers become available.

We would like to thank the developers, documenters, testers and all the many folks out there who volunteer their time and effort (or fund people to do so). From the QGIS community we hope you enjoy this release! If you wish to donate time, money or otherwise get involved in making QGIS more awesome, please wander along to qgis.org and lend a hand!

QGIS is supported by donors and sponsors. A current list of donors who have made financial contributions large and small to the project can be seen on our donors list. If you would like to become and official project sponsor, please visit our sponsorship page for details. Sponsoring QGIS helps us to fund our six monthly developer meetings, maintain project infrastructure and fund bug fixing efforts. A complete list of current sponsors is provided below – our very great thank you to all of our sponsors!

QGIS is Free software and you are under no obligation to pay anything to use it – in fact we want to encourage people far and wide to use it regardless of what your financial or social status is – we believe empowering people with spatial decision making tools will result in a better society for all of humanity.

CARTO Inside Blog: CARTO's Use of Foreign Data Wrappers

Planet OSGeo feeds - Fri, 02/23/2018 - 11:39

PostgreSQL is packed full of under-appreciated features (pg_trgm, full-text search, logical replication, ranges, to name a few) but I’d like to highlight one feature that we use under the covers in CARTO more than you might expect: foreign data wrappers.

Foreign data wrappers (FDW for short) allow developers to expose external sources of data as tables inside PostgreSQL. For data sources that are already tabular, FDW just looks like a mirror of a remote table (Oracle FDW, MySQL FDW, etc), where local queries are magically fulfilled by the remote server. For other data sources (Twitter FDW, passwd FDW, random number FDW, etc) the FDW developer maps the external source into a tabular shape, where queries can be evaluated against the source and still returned as a PostgreSQL tuple set.

CARTO’s use of FDW is pretty conventional:

  • We use postgres_fdw to link data in remote databases to users Carto databases, and,
  • We use odbc_fdw to expose data in customer’s operational databases to their CARTO instances.

In both cases, the FDW connection allows us to provide data access without incurring the cost and complication of replicating that actual data from one database to another.

Push Queries to Remote Servers Faster with postgres_fdw

The native postgres_fdw ships with PostgreSQL and is naturally the most full-featured FDW implementation – there is an almost perfect mapping of features from one instance of PostgreSQL to another, so the FDW can be very clever about pushing queries to the remote server.

During development, when we joined local spatial data with remote data we found that PostGIS types and functions weren’t being sent to the remote server. That rendered remote data access impossibly slow.

To achieve our ends, we had to extend postgres_fdw to support the PostGIS geometry types and functions, so that spatial queries could be sent to the remote server.

In order to get our enhancements accepted into the PostgreSQL community, we then generalized them to support any PostgreSQL extended type.

When creating a foreign server definition with spatial data, just add an extensions option to let FDW know that it is safe to ship PostGIS objects and functions to the remote server.

CREATE SERVER foreign_server FOREIGN DATA WRAPPER postgres_fdw OPTIONS ( host '192.83.123.89', port '5432', dbname 'foreign_db', extensions 'postgis' );

With the “extension shipping”, it’s possible to make use of any custom type or function over a a postgres_fdw connection as long as it is a part of an extension that is installed in both the local and remove databases.

Schedule Live Data Syncs with odbc_fdw

CARTO Database Connectors allow users to connect their CARTO instances directly to remote databases, with queries that can be refreshed on a schedule. For folks with live data they want to feed into analysis and display, the database connectors can be very useful!

Under the covers, the connectors are setting up and managing odbc_fdw connections between the CARTO instance and the remote databases. By using the generic ODBC driver as the base for our connectors, we can support connections to

  • MySQL,
  • PostgreSQL,
  • SQL Server, and
  • Apache Hive.

In order to keep up with new PostgreSQL releases, as we upgrade our infrastructure to the latest version, we have taken on the maintenance of the odbc_fdw.

gvSIG Team: GIS applied to Municipality Management: Module 14 ‘Image georeferencing’

Planet OSGeo feeds - Thu, 02/22/2018 - 10:22

The video of the fourteenth module is now available, in which we will show how to georeference an image.

Sometimes the technicians of a city council have images that are not georeferenced. They also can have an old map on paper, the data of which are needed to perform some analysis on their desktop application, such as delimiting the municipality in detail for example. That map on paper could be scanned so that they would have an image on their hard disk. And they would have to georeference it then.

The cartography to follow this video can be downloaded from this link.

GeoServer Team: GeoServer 2.13-beta released

Planet OSGeo feeds - Thu, 02/22/2018 - 01:45

We are happy to announce the release of GeoServer 2.13-beta. Downloads are available (zipwar, and exe) along with docs and extensions.

This is a beta release of GeoServer made in conjunction with GeoTools 19-beta.

We want to encourage people to test the release thoroughly and report back any issue found. With no further delay, let’s see what’s new, that is, what is there to test!

Isolated Workspaces

The concept of an “Isolated Workspaces” has been added to GeoServer, to allow for reusing a namespace among multiple workspaces. In particular, an isolated workspace allows reuse of a namespace already used by another workspace, but its resources (layers, styles, etc …) can only be retrieved when using that workspace’s virtual services and will only show up in those virtual service capabilities documents.

When reusing a namespace among workspaces, exactly one of those must be non-isolated, and the rest must be isolated; i.e. isolated workspaces have no restrictions in namespaces usage but the existing restrictions still apply for non isolated workspaces.

For more details, refer to the original proposal.

GeoWebCache REST API

Two new endpoints have been added to the GeoWebCache REST API:

  • /gwc/rest/blobstores:
    • GET /gwc/rest/blobstores for a list of the blobstores
    • GET /gwc/rest/blobstores/{blobStoreName} for details about a single blobstore
    • PUT /gwc/rest/blobstores/{blobStoreName} to create or update a blobstore
    • DELETE /gwc/rest/blobstores/{blobStoreName} to remove a blobstore
  • /gwc/rest/gridsets:
    • GET /gwc/rest/gridsets for a list of the gridsets
    • GET /gwc/rest/gridsets/{gridSetName} for details about a single gridset
    • PUT /gwc/rest/gridsets/{gridSetName} to create or update a gridset
    • DELETE /gwc/rest/gridsets/{gridSetName} to remove a gridset

API docs for these endpoints will be added to the GeoServer documentation shortly. Until then, the request body syntax for PUT requests closely matched the equivalent structures in geowebcache.xml: BlobStores and GridSets.

The ArcGISCache backed layers are now also configurable via the REST API.

This release sees a major reworking of the configuration system in GeoWebCache that will allow for plugging in alternate configuration persistence mechanisms in future. While these changes should be largely invisible to users, it is a huge update that impacts all of GeoWebCache. However, due to these changes, we ask that you please test the embedded GeoWebCache.

UI Improvements

Entering in URLs for data files has been improved with autocomplete – now GeoServer will scan the path that has already been typed, and suggest existing files within that path.

In addition, autocomplete support has been added to a number of dropdowns which contain a long list of values, such as stores or layers. You can now start typing the name of an option, and the visible options will be filtered to match.

Removed OS X installers

Due to lack of resources and interest, the OS X dmg installers are no longer being built. OS X users can still use the system-independent binary.

New community modules

The 2.13 series comes with a few new community modules, in particular:

  • Do you want to generate GHRSST compliant outputs from GHRSST inputs? Try out the new GHRSST NetCDF output community module.
  • There is also a new community module introducing NSG profiles for the WFS and WMTS services.

Not that community modules are not part of the release; instead you can find them in the nightly builds.

Other assorted improvements

There are many bug fixes and improvements to look at in the release notes, cherry picking a few here:

  • Autocomplete support for dropdowns with long lists of values
  • Upgrade JDom library
  • REST API CORS support
  • REST improvements to list all layers in a workspace, and include the workspace prefix in layer listings
  • Style POST does not support non-SLD styles
  • Add WMTS RESTful API
  • Installing the XSLT plugin may cause random REST endpoints to report lists with transforms/transform
  • WCS 1.0.0 does not handle FORMAT parameter properly
  • Cache small amount of features in memory to avoid repeated data scans in GetFeature requests
  • Allow requesting both OL3 and OL2 from the client side
  • Simple feature GML 3.2.1 output schema-invalid as geometries lack mandatory gml:id
  • GeoPackage generated via WPS has y coordinates starting from bottom left
  • Numerous WFS 2.0 bugfixes
  • Submitting a seed/truncate request for a tile layer results in a “406, not acceptable”
  • GWC Seed Form returns “Chunk [] is not a valid entry” message error when seeding a layer.
  • Demo Page does not send password
Test, test, test!

Now that you know about all the goodies, please go, download and test your favourite ones. Let us know how it went!
