While working on the latest release of our Livecd, we prepared a custom version to be used by FOSS-GIS training course participants during the FOSS4G2008 in Cape Town. All the specifications were decided in collaboration with Moritz Lennert, whom we would like to thank for all the support while I was without an Internet connection.
The DVD is a Xubuntu system containing recent versions of:
It also contains the new North Carolina GRASS demo data set, next to the old Spearfish data set.
On the DVD, there is also a special win/ folder with the following windows installers:
Thanks to the Oficina del Historiador I've been invited to give a course over Web Mapping and OGC Standards. Oficina del Historiador is the efficient institution that is restoring the historical center of La Habana, the capital of Cuba.
During my days in this beautifully town I've been invited to do a couple of conferences about OSGeo and its Spanish-speaking Local Chapter. The Cuban community is definitely interested in FOSS and I've found a lot of enthusiasm between different institutions. Possibly we'll soon see a Cuban event on FOSS4G.
presenting OSGeo at the UCI conference
In these days, I've been lucky to be invited to visit the Universidad de las Ciencias Informáticas (UCI) and give a conference there too. This university has 10.000 students focused on IT, an "army" of programmers. It would be cool to do some workshops there next time I'll be in Cuba.
Last note on gvSIG. During my courses I had the chance to test the new add-on that allow to export the current View as a mapfile for UMN Mapserver. I love this tool, it make it easy to everybody do create a usable mapfile. Hope to see it published soon.
This is the most important feature we've developed lately with Kappu (aka Andrea Cappugi).
OWS Manager has a simple interface to deal with SLDService.
Last summer I've published a first example of WMS Manager.
It is a concept interface for OpenLayers to deal with WMS servers.
Now is on process to become an AddIn for OpenLayers.
Lately, working on other OGC standards integration, I've changed the name of this concept application to OWS Manager.
OWS Manager aims to deal with:
- Web Map Context (WMC): read/write support.
- Web Map Service (WMS): manage maps from multiple servers passing through getCapabilties request. Improved LayerList to deal with multiple layers from different WMS servers.
- Style Layer Descriptor (SLD): edit styles for WMS layers using SLDService for GeoServer (extension made by Kappu).
- Catalogue Service for Web (CSW): search on a CSW interface (ex: GeoNetwork).
I would like to show some screencasts to explain what's already done and I will split this thread in some posts. Let's start with WMS.
Web Map Service (WMS)
In this screencast you can see how to add layers to the map choosing form a list of WMS Servers and then how to make a query to the queryable layers.
When a server is chosen the getCapabilities is requested and the result is parsed and shown on a multi-select list. You can select one or more layers and even move the vertical order of appearance.
The output format for every layer can be specified between the formats available in the server. Openlayers' Overlays can be requested by checking the appropriated box.
When WMS layers are queryables a "(q)" symbol is shown and the Query function returns GetFeatureInfo outputs "drilling" all queryable layers.
