gvSIG Team: Map of the most dangerous cities in the world

OSGeo Planet - Sat, 2018-05-05 11:23

As many of you know, in the gvSIG Association we have an open source software solution for the analysis and management of information related to crime and citizen security, gvSIG Crime. One of the technologies used in gvSIG Crime is gvSIG Online, that allows to generate geoportals, as simple or complex as we need, among many other things.

Precisely with gvSIG Online we have created a simple map viewer that allows us to visualize the 50 most dangerous cities in the world based on the homicide rate in the last year (2017).

To access the map click here

Without a doubt, it is striking that 47 cities of these 50 cities are located in America, and 42 in Latin America.

The information presented is drawn from the last report of the Citizen Council for Public Safety and Criminal Justice (CCSPJP – Consejo Ciudadano para la Seguridad Pública y la Justicia Penal), a Mexican civil organization that generates the list of the 50 most dangerous cities in the world every year. For this report, which annually is an international reference, the CCSPJP uses a simple methodology, comparing the number of homicides per 100,000 inhabitants. They include only those cities that exceed 300,000 inhabitants and compute only intentional homicides or deaths due to aggression. The areas where there is a war conflict are excluded.

The data is extracted by combining several sources: journalistic information, official lists of governments and local authorities, reports from international organizations and NGOs.

Through this geoportal you can visualize the cities, request information about each of them on the number and annual homicide rate, consult the attribute table and search.

Here you have the video about the map and how the geoportal works:

Finally we take the opportunity to announce that we will publish a free course about gvSIG Desktop applied to criminology. Pay attention if you are interested in this issue…

gvSIG Team: Crear nuevas rampas de color en gvSIG Online

OSGeo Planet - Fri, 2018-05-04 15:00

Como todos sabréis una imagen raster la podemos representar utilizando una ‘Tabla de color’. Esas tablas de color se generan a partir de rampas de color. En gvSIG Online disponemos de .una serie de rampas de color pero para ciertos casos nos puede interesar crear una nueva. No hay ningún problema, gvSIG Online nos permite hacerlo.

Os mostramos mediante un vídeo-tutorial cómo hacerlo. En el vídeo se siguen los siguientes pasos:

  1. Tenemos un geoportal con un ráster al que queremos aplicar una determinada simbología (Tabla de color). Imaginemos que ninguna rampa de color de las pre-existentes cumple con lo que queremos aplicar.
  2. Entramos en la parte de administración y vemos que en nuestro gvSIG Online hay distintas bibliotecas de símbolos que contienen una serie de rampas de color.
  3. Añadimos una nueva biblioteca de símbolos que contenga dos nuevas rampas de color. Para cada rampa indicamos los colores que la configuran.
  4. Por último aplicamos una Tabla de color a nuestra capa ráster, utilizando las nuevas rampas de color disponibles.

Como veis, gvSIG Online crece día a día en funcionalidad y se está convirtiendo en un referente a la hora de implantar Infraestructuras de Datos Espaciales.

gvSIG Team: El mapa de las ciudades más peligrosas del mundo

OSGeo Planet - Wed, 2018-05-02 07:01

Como muchos de vosotros sabréis en la Asociación gvSIG disponemos de una solución en software libre para el análisis y la gestión de información relacionada con el delito y la seguridad ciudadana, gvSIG Crime. Una de las tecnologías que se utiliza es gvSIG Online, que entre otras muchas cosas permite generar geoportales, tan sencillos o complejos como necesitemos.

Precisamente con gvSIG Online hemos creado un sencillo visor de mapas que permite visualizar las 50 ciudades más peligrosas del mundo en función de la tasa de homicidios del último año (2017).

Para acceder al mapa haz click aquí

Sin duda llama la atención que de las 50 ciudades 47 estén ubicadas en América y 42 en América Latina.

La información presentada está extraída del último informe del Consejo Ciudadano para la Seguridad Pública y Justicia Penal (CCSPJP), una organización civil mexicana que cada año elabora un listado con las 50 urbes más violentas del mundo. Para este informe, que anualmente es un referente internacional , el CCSPJP utiliza una metodología sencilla, comparando el número de homicidios por cada 100.000 habitantes. Incluyen únicamente aquellas ciudades que superan los 300.000 habitantes y computan solo los homicidios intencionales o muertes por agresión. Se excluyen las zonas donde hay un conflicto bélico.

Los datos se extraen combinando varias fuentes: informaciones periodísticas, listas oficiales de los gobiernos y autoridades locales, informes de organismos internacionales y ONG.

Mediante este geoportal podréis visualizar las ciudades, solicitar información de cada una de ellas sobre número y tasa anual de homicidios, consultar la tabla de atributos y hacer búsquedas.

Vídeo sobre el mapa y el funcionamiento del geoportal:

Por último aprovechamos para anunciar que en breve vamos a publicar un curso gratuito de gvSIG Desktop aplicado a criminología. Estad atentos si os interesa el tema…

GeoSolutions: One click away from GeoNode with Rancher and Docker

OSGeo Planet - Tue, 2018-05-01 17:19

GeoNode branding

Anyone who has had the chance to install GeoNode knows that setting it up means having to deal with a whole stack of software components. PostgreSQL/PostGIS, Geoserver, Celery, RabbitMQ, ElasticSearch are the key elements for a complete GeoNode setup that allows to exploit the complete set of functionalities offered by the platform.

GeoNode provides a setup procedure (based on Paver) that simplifies the process for testing and development purposes, but a production-ready deployment requires more steps to configure and integrate the individual components to offer a reliable and robust setup.

Docker, Rancher and GeoNode

The past years have seen the rise of DevOps technologies that help a lot in managing deployment operations, comprising CI/CD pipelines, and in configuring services to provide scalability, security and availability. Linux containers, and Docker in particular, has won the trust of developers, DevOps and sysadmins, providing widely adopted approaches for these tasks. A fast growing ecosystem of tools and platforms has been built on top of it, from Docker Compose to Rancher to offer streamlined operations and services for the building of cloud infrastructures and distributed services. GeoNode did not miss the DevOps  train, a set of Docker images has been defined along a Compose configuration to make it possible to deploy the whole GeoNode stack as a group of interlinked containers. The design of the GeoNode "dockerization" is still undergoing thanks to a joint effort from various subjects within the community, where GeoSolutions is actively participating to offer its contribution and experience.

To meet the needs of our current scenarios we have created a custom Docker and Rancher setup, specifically targeted at setting up multiple deployments of GeoNode as easy and quick as possible. The goal was having a one or two click away vanilla GeoNode setup, leveraging single or multiple hosts infrastructures while providing at the same time the ability to customize its look and feel without touching any line of code.

[caption id="attachment_3995" align="aligncenter" width="960"]GeoNode hosts with Rancher and Docker GeoNode instance with Rancher and Docker[/caption]

The result was the "GeoNode Generic" project template for Docker Compose template v.2 and Rancher 1.6 It can be loaded directly from Rancher UI defining a custom catalog pointing to the GitHub project's repository.

[caption id="attachment_3989" align="aligncenter" width="1024"]GeoNode Generic Rancher template GeoNode Generic Rancher template[/caption]   GeoNode Generic deployment with Rancher

This is a Django project partly based on the GeoNode project template, with a dedicated Docker and Rancher template files  from which new instances can be deployed and run with a minimal effort. Define the host environment, answer a few (mostly optional) questions et voilà, here you have a fresh new GeoNode instance, with backup services and monitoring already enabled and running.

[caption id="attachment_3992" align="aligncenter" width="1024"]Geonode Geneirc stack configuration Geonode Geneirc stack configuration[/caption]

The stack comprises five containers running the PostgreSQL/PostGIS DB, Geoserver, the GeoNode Django app, the Nginx HTTP Server exposing the public endpoints of GeoNode, and one container dedicated to persistent data storage (uploaded data, GeoNode's static files, etc.).

Cron schedules for backup and monitoring tasks (metrics collection) are run from the GeoNode Django app container, where uWSGI cron facilities are used for this purpose.

[caption id="attachment_3994" align="aligncenter" width="1024"]Running containers Running containers[/caption]

In this example only one container instance for each image is running. The number of GeoNode and Nginx instances can be increased and put behind Rancher's Load Balancing services to provide a basic HA. In the future Kubernetes orchestration, instead of Cattle, will be considered to take advantage of its powerful tools for rolling releases management and advanced HA and FailOver services.

UI Customization

Until a few days ago applying some branding to GeoNode could only be obtained with customizing its CSS and Django templates files. This still remains true if deep customization is needed but now you have the opportunity to define basic frontend styling thanks to the brand new (no pun intended) "themes" feature, developed by GeoSolutions and already available for the development version of GeoNode.

The "themes" configuration allows to define multiple themes offering:

  • custom logo
  • custom header background image
  • custom header title and message
  • custom color for header and background
  • contacts block in footer
  • copyright message in footer
A list of "partners" can also be defined with their own logos. If partners are defined a custom block in included before the footer, listing the logos which can link to the partner websites. [caption id="attachment_3997" align="aligncenter" width="1024"]Theme admin excerpt Theme admin excerpt[/caption]  

Combining GeoNode's deployment through Rancher templates and themes customization we obtained a fast workflow for our customers, permitting to create new instances for their infrastructures at the speed of a click.

[caption id="attachment_3998" align="aligncenter" width="700"]GeoNode branding GeoNode branding[/caption]

Last but not least, we would want to thank the GFDRR group at the World Bank as well as the GIS Department of the City of  Genova (Italy) which provided the funding for this work.

QGIS Blog: Preparing for the next LTR

OSGeo Planet - Tue, 2018-05-01 06:49

Dear QGIS users,

As you know, QGIS 3 has recently been published. This version introduced big changes in  the code structure that, in addition to the new functionalities already exposed, makes our code base more modern and easier to expand and improve on in the future.

As a normal by-product of such a huge overhaul, these changes also triggered a series of new issues, that you, our users are helping to discover and document. Our objective is to eliminate the most important of these issues in time for what will be our next Long Term Release (LTR) – version 3.4. This release is scheduled for October 2018. The resources available from QGIS.ORG funds are limited, and we have already invested in QGIS 3.0 far more than we have done for any previous version.

Now is a great time for users, and particularly for power users, larger institutions and enterprises, to invest in QGIS bugfixing. You have a number of different options: donating your developers’ time or hiring a developer directly to resolve the bugs that annoy you most, sponsoring our foundation, or donating to QGIS.ORG.

Our targets are:

  • 20k€ within 2018-05-18 (for 3.2)
  • 40k€ within 2018-09-14 (for 3.4)

If you would like to help, feel free to contact us (preferably through the qgis-users or qgis-developers mailing list, or directly to info@qgis.org) for further details!

gvSIG Team: ETL in gvSIG Online, importing data in an SDI easily

OSGeo Planet - Mon, 2018-04-30 14:38

An ETL (Extract, Transform and Load) plugin has been developed in gvSIG Online, that allows to define a transformation process to import data like CSV files and Excel spreadsheet as layers available in a Spatial Data Infrastructure. In this way, gvSIG Online has tools that allow organizations that have it implemented to reformat and clean source data and load them in the spatial database of the SDI.

When a concrete information is generated in a usual way in formats such as those indicated (csv, xlsx), this functionality greatly makes data loading easy, without requiring users to use other applications to perform the transformation.

We are going to show a video with a demonstration about how it works. The steps for that are:

  1. We have to upload a Microsoft Excel spreadsheet (xlsx) to gvSIG Online.
  2. We create an empty layer with a series of fields.
  3. We define the transformation to be applied. That is, it indicates how to fill in that empty layer with the data contained in the spreadsheet.
  4. We check that the transformation was successful in a geoportal.

gvSIG Team: ETL en gvSIG Online, pasar datos fácilmente a la IDE

OSGeo Planet - Mon, 2018-04-30 14:23

En gvSIG Online se ha desarrollado un plugin ETL (Extract, Transform and Load) que permite definir un proceso de transformación para pasar datos como archivos CSV y hojas de cálculo Excel a capas disponibles en la Infraestructura de Datos Espaciales. De este modo gvSIG Online cuenta con herramientas que permiten a la organización que lo tiene implantado el reformatear y limpiar los datos de origen y cargarlos en la base de datos espacial de la IDE.

Cuando cierta información se genera de forma habitual en formatos como los indicados (csv, xlsx) esta funcionalidad facilita enormemente la carga de datos, sin requerir por parte de los usuarios el uso de otras aplicaciones para realizar la transformación.

Vamos a ver en un vídeo una demostración de cómo funciona. Los pasos que se realizan en esta demostración son:

  1. Subimos a gvSIG Online una hoja de cálculo de Microsoft Excel (xlsx).
  2. Creamos una capa vacía con una serie de campos.
  3. Definimos la transformación a aplicar. Es decir, indicamos como rellenar esa capa vacía con los datos que contiene la hoja de cálculo.
  4. Comprobamos en un geoportal que la transformación se ha realizado correctamente.

Petr Pridal: OpenMapTiles 3.8

OSGeo Planet - Mon, 2018-04-30 11:00

The new release of open-source project OpenMapTiles 3.8, which offers world maps based on OpenStreetMap, brings evolutionary steps rather than revolution. However, a significant number of small-scale changes in the transport layer, water, and other features improves the map look significantly.

Transportation layer

Navigating through multi-level stack interchange could be challenging. Having a map representing all the layers is very helpful at that moment. Therefore, we imported the so-called z-index into OpenMapTiles 3.8 and made a map style which transparently navigates you visually through all roads even in the complicated crossings called spaghetti junction. The downside of this solution is the size which rises about four times compared to the same style without multilevel crossing. It increases computing requirements for saving into a database, downloading, parsing and rendering and therefore it is not switched on in the base styles. What stays turned on by default is another new attribute: bridge polygon.

Turn-by-turn navigation is easier with 83 000 imported one-way roads and flexibility to use different types of transportation has been extended by adding tube entrances and other stations.

OpenMapTiles Spaghetti Junction The intersection which was first nicknamed as Spaghetti Junction: Gravelly Hill Interchange in Birmingham, England.

Water features

The water layer was enriched by layered features as well. With the new OpenMapTiles release, water bridges and functioning aqueducts are presented in the data as well as in the styles. The same is true for underground watercourses, where streams flowing in culverts or caves are now rendered as a dashed line, which is a common representation of this kind of features.

In the previous versions, there were missing labels for some bigger water features, namely seas. Since version 3.8, there should be a label for the Caribbean Sea, Mediterranean Sea, Caspian Sea, Sea of Japan, Celtic Sea and the Chukchi Sea. Also, bigger bays like Bay of Biscay or Gulf of California are now displayed.

OpenMapTiles culvert

There is a culvert under the famous Nieuwmarkt square in Amsterdam, the Netherlands.

Other changes

One of the significant features which made it to OpenMapTiles 3.8 is sand and beach in the landcover layer. It is also possible to distinguish religions in the places of worship. Some people were confused by borders around leased territories and therefore it is now switched off by default in the styles. This is the case of the Guantanamo Bay Naval Base or Baikonur Cosmodrome, where the second one is leased to Russian government until 2050, but it is located in the heart of neighboring Kazakhstan. The leased area has an oval shape measuring 85 and 90 kilometers in diameter.

From Wikipedia: The spaceport is currently leased by the Kazakh Government to Russia until 2050, and is managed jointly by the Roscosmos State Corporation and the Russian Aerospace Forces.

List of all changes can be found as usual on GitHub altogether with the source code. You can visually go through all changes on MapTiler Cloud hosting or download the data and styles from OpenMapTiles.com.

Baikonur Cosmodrome Baikonur Cosmodrome leased to Russia until 2050, is located in the heart of Kazakhstan.

OSGeo.nl: Verslag: NLExtract Hacking Day

OSGeo Planet - Mon, 2018-04-30 09:47

Afgelopen donderdag (26 april) was de eerste NLExtract Hacking Day, ruim zes jaar nadat de huidige Github repo is aangemaakt en bijna zeven jaar nadat BAGExtract+ door Matthijs van der Deijl online is gezet. De opkomst was zeer goed te noemen, met 14 man en één dame, waaronder de voltallige bezetting van zowel Webmapper als Geogap. Een gevarieerd gezelschap, maar met de nadruk op ontwikkelaars. We werden gastvrij ontvangen door Webmapper bij de Social Impact Factory in Utrecht. De lunch en borrel werden gefinancierd uit het bedrag dat NLExtract won bij de OGT-Award in 2016.

Verbeterpunten en wensen NLExtract

Verbeterpunten en wensen

Aangezien we voor de eerste keer met zo’n grote groep mensen bijeen waren voor NLExtract, leek het ons een goed idee om te inventariseren wat de belangrijkste wensen en verbeterpunten voor NLExtract te zijn. Dit bleken te zijn, in willekeurige volgorde:

  • User interface: met name door niet-ontwikkelaars gewenst;
  • Documentatie: altijd een ondergeschoven kindje;
  • Unit tests / continuous integration: nodig om stabiele en reproduceerbare deliverables te maken;
  • Geopackage output: simpeler in gebruik dan PostGIS-dumps;
  • Vector tiles: basisregistraties gelijk hier naar toe omzetten;
  • Community building: hoe houd je en grotere groep mensen betrokken bij NLExtract;
  • Aanvullende tools: data-analyse, kwaliteitsanalyse, standaard “recepten”, verrijkingen;
  • Docker: gemakkelijker in gebruik dan zelf alle dependencies te installeren.
Het vector tiles team

Het vector tiles team

Door diverse mensen werden verschillende onderwerpen opgepakt, zoals Docker, vector tiles, verbeteren van de website, kwaliteitsanalyse v.w.b. schrijfwijzen namen, etc. Tevens hebben enkele mensen zich verdiept in het gebruik van NLExtract. Het is soms lastig aan de praat te krijgen, met name op Windows. Dit komt voor een groot deel door de verschillende dependencies (PostgreSQL, PostGIS, GDAL, Python, enkele Python-libraries) waarvan de installatieprocedure wijzigt en die deels weer afhankelijk zijn van elkaar.

Aan het eind van de dag werd het volgende gemeld t.a.v. voortgang:

  • Kwaliteitsanalyse: er zijn enkele scripts gemaakt voor de analyse van BGT-namen en BAG-adressen.
  • Gebruik NLExtract: degenen die zich wilden verdiepen in het gebruik van NLExtract zijn wijzer geworden.
  • Geopackage: een deel van de BGT van Schiermonnikoog e.o. werd in Geopackage geladen. Nog niet alle informatie bleek geladen (nummeraanduidingen bij panden, kruinlijnen).
  • Docker: de NLExtract repo is onder handen genomen als voorbereiding voor het verdockeren. Spullen die niet met basisregistraties te maken hebben, zijn verplaatst.
  • Website: de website is geactualiseerd en beter georganiseerd.
  • Vector tiles: er zijn verschillende tools (Tegola, Tileserver GL, T-Rex) nader geanalyseerd en gebruikt op hun geschiktheid om de data van de basisregistraties naar vector tiles over te zetten. Dit resulteerde in een demo met kadastrale informatie.
Hard werken aan NLExtract

Hard werken aan NLExtract

We kijken terug op een zeer geslaagde dag waar met veel energie en passie aan NLExtract werd gewerkt. We zijn van plan om in de toekomst nog meer van dergelijke dagen te organiseren.

gvSIG Team: Layers with multiple legends on a Geoportal with gvSIG Online

OSGeo Planet - Thu, 2018-04-26 13:12

We are going to show you more gvSIG Online tools, the platform for Spatial Data Infrastructures that doesn’t stop growing. In this case we are going to talk about the tool for multiple legends, a really useful functionality when we want to show a same layer with different legends in a Geoportal. Surely more than once you have found that problem… that gvSIG Online solves easily.

The steps to be followed for this are shown in the video:

  1. From the dashboard, several legends are created for the same layer: one for a single symbol, another for unique values and another for grouping points.
  2. In a geoportal created with gvSIG Online, from the table of contents we can see how we can select the different legends available in the layer and it is automatically applied.

Easy and extremely useful, right?

gvSIG Team: Capas con múltiples leyendas en un Geoportal con gvSIG Online

OSGeo Planet - Thu, 2018-04-26 11:02

Os seguimos mostrando herramientas de gvSIG Online, la plataforma para Infraestructuras de Datos Espaciales que no para de crecer. En este caso vamos a hablar de la herramienta de leyendas múltiples, una funcionalidad realmente útil cuando queremos mostrar una misma capa con diferentes leyendas dentro de un Geoportal. Seguro que más de una vez os habéis encontrado con ese problema…que gvSIG Online resuelve fácilmente.

Los pasos seguidos para ello se muestran en el vídeo:

  1. Desde el área de administración se crean varias leyendas para una misma capa: una de símbolo único, otra de valores únicos y otra de agrupación de puntos.
  2. En un geoportal creado con gvSIG Online, desde la tabla de contenidos vemos como podemos seleccionar las distintas leyendas disponibles en la capa y automáticamente es aplicada.

¿Fácil y extremadamente útil, verdad?

gvSIG Team: Raster time series in an SDI: Temporary image mosaics in gvSIG Online

OSGeo Planet - Thu, 2018-04-26 10:52

If a few days ago we presented the abilities of working in gvSIG Online with vector data in 4D, today we show you how you can also work with temporary series of images.

In the video of this post we can see the process to publish raster from different dates in a geoportal. The steps to be followed are:

  1. We upload the data to the platform. In this case we upload 4 images from different dates.
  2. We indicate that this set of images is a time series in gvSIG Online.
  3. We publish the mosaic of temporary images, configuring the temporary parameter. The list of available layers to use is shown in the geoportals.
  4. We create a geoportal with that layer (the temporary raster series). We check that it is displayed.
  5. To improve the visualization we apply a colour layer.
  6. We can see the changes in the geoportal and we use the temporary filter to consult the data.
