Spatial Data Infrastructures for Guatemala

The Prototype of Spatial Data Infrastructure for Guatemala, which is being prepared by the Secretary General of Planning and Programming of the SEGEPLAN Presidency, is interesting. 

We had seen in the presentation video of Moisés Poyatos and Walter Girón Of SITIMI in the 4th. gvSIG conferences; At the end of the presentation they mentioned that IDEs were a hot topic in Guatemala but to date they had not shown anything publicly. Now they have done it through the gvSIG mailing list and I think it is worth recognizing that it is a great job that is just beginning, although Jean-Roch Lebeau had told me a little about it.

Well, SEGEPLAN pretends within the environment of the new Law of Territorial Ordering To promote the development of Spatial Data Infrastructures in Guatemala, interesting that they are seriously considering Free Software. This Prototype Uses:

• Postgre (Geographic Module POSTGIS)
• gvSIG for the generation of spatial services scripts
• Apache for Web server
• Mapserver as a Maps server
• Mapbender as a thin client.
• And the GEONETWORK Metadata Module Publication is in process.

This is extremely valuable and a good reference for the Central American region where other apps have Short, not only because of what the investment in proprietary software implies, but also because of the taste for OGC standards. To see how the system works:

Enter in the system

He has not yet been baptized with a name that gives him a corporate identity, we assume he will be part of Sinit; because the prototype level is the link address that you now have, http://ide.segeplan.gob.gt/ , There is entered the user and password "ide" and thus has a display of graphical information.

Download layers

Here, among the data served, you can choose relief, high-resolution orthophotos and departments. Once the layer is chosen, the available layers can be chosen and below are some tabs for legends, print and search.

In the upper icons there are basic functionalities of approach and deployment but there are also other very interesting as the loading of layers wms:

In the order would be these:

Deployment:

• Getting closer
• Walk away
• Travel
• Window Zoom
• Center
• Displacement
• Refresh
• Previous zoom
• Next zoom

Information:

• Data search
• Show coordinates
• Measure distance

Access wms:

• Add wms from filtered list **
• Add wms
• Adjust wms. **
• Show info about wms

For now, those marked with an asterisk have a programming error since they refer to a localhost and not to a web server. It also lacks some refinement in the character encoding that does not allow the letter ñ to be seen well in "add".

Others:

• Help
• Save file as web map context
• Upload web map file context
• Close
• Manually Modify Deployment Size

Connect from Google Earth

The system provides the opportunity to connect to data either wfs or wms; So that any program that supports standard OGC services could stick to it (GvSIG, ArcGIS, AutoDesk Civil 3D, Bentley Map, manifold CHALK, CadCorpEtc.).

Let's see how, for example, systems such as Google Earth can be pasted into the system:

We are going to “add, image overlay”, then we choose the “update” tab and there we choose the “wms parameters” option. We then add a url:

http://www.segeplan.gob.gt/2.0/index.php?option=com_wrapper&view=wrapper&Itemid=260;
REQUEST = GetMap & SERVICE = WMS & LAYERS = Municipalities,
Departments_850, Portfolio_Areas.shp, Water bodies, Headers
Departamentales_800, Rios_200, Roads, Routes
Asfaltadas_850 & STYLES = ,,,,,,, & SRS = EPSG: 42500 & BBOX = 420673.5340388007,
1610754.0839506174,466326.4659611993,1642245.9160493826 & WIDTH =
893 & HEIGHT = 616 & FORMAT = image / png & BGCOLOR = 0xffffff & TRANSPARENT =
TRUE & EXCEPTIONS = application / vnd.ogc.se_inimage

This can be obtained from the different addresses in the mapbender metadata layer, (from the orange button). There are more urls of the other layers available there.

Once deployed that the system allows to choose which layers we want to see and the order

And ready:

Additionally, I recommend you take a look because there is much more to show in this project.
