Hola America del Sur! Aqui se unen las personas interesadas en FOSS Geo.

Bienvenido al nuevo foro de software geográfico libre en español.

Invitacion al III Encontro Nacional de Usuarios MapServer en Brasil.

Lista de Participantes

[= Tutorial = La Fundación OSGeo organiza información sobre software libre y abierto (Free & Open Source). Para conocer más acerca de las actividades que adelanta la Fundación OSGeo consulte la sección "Documentos" del Visisbility Committee.

Cambio de Paradigma en GIS

El artículo Proprietary to Open Source: A paradigm shift publicado en GIS@Development describe cómo desarrollar SIG (Sistemas de Información Geográfica -GIS) con estándares del OGC (Open Geospatial Consortium) y SOA (Service Oriented Architectures).

Interoperabilidad

Spatial data does not stop at given borders. Therefore it is important to make the systems that host them interoperable. One standards organization in the spatial realm is the OGC (Open Geospatial Consortium) who defined the interface specifications WMS to get maps and WFS to get the corresponding features. Those features are coded in an XML schmea called GML (Geographic Markup Language) another standard as defined by OGC. In the following section some of these services can be seen and tested.

Test WMS Services

Use the OSGeo Mapbender installacion to create an account.

Log on with your new account. From the list that is displayed select and open the user interface called gui. (As a tip, it might be easier to use the browser software Firefox because it can open several browser tabs in the same window and comes with tools to analyze web applications).

After opening the interface you see a map with several services, they come from different places in the world (to be able to access them you need to be online!). Browse around and have a look at the different datasets.

You can add more services by typing in the Capabilities Request of the service. Open the button called Adding WMS and type in the following WMS GetCapabilities request:

http://siaiacad09.univali.br/cgi-bin/map461?map=/home/apache/mapserv/simmam/simmam.map&REQUEST=GetCapabilities&VERSION=1.1.1&SERVICE=WMS (this is the Capabilities URL of an old demo server from Brazil kindly provided by Univali)

Click on the page symbol called "Show service metadata", here you can see all the URL that produce the combined map:

DEMIS
JPL World Map (NASA)
Germany
Mapbender Users
Brazil (The Brazil Service has been added dynamically)
El servicio Invemar para Monitoreo de Calidad de Aguas Marinas y Costeras no es estandarizado.
