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 4tas. gvSIG days; 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 bit 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 for what implies the investment in proprietary software but for the taste for the 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.
Here among the data served you can choose emboss, high resolution orthophotos and departments. Once the layer is chosen you can choose the available layers 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:
- Getting closer
- Walk away
- Window Zoom
- Previous zoom
- Next zoom
- Data search
- Show coordinates
- Measure distance
- Add wms from filtered list **
- Add wms
- Adjust wms. **
- Show info about wms
For now, those marked with an asterisk have a programming error because they are referred to a localhost and not to a web server. It also lacks some refinement in the coding of characters that does not allow to see well the letter ñ in "add".
- Save file as web map context
- Upload web map file context
- 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 choose the "update" tab and there the "wms parameters" option is chosen. Then add a url:
REQUEST = GetMap & SERVICE = WMS & LAYERS = Municipalities,
Departments_850, Portfolio_Areas.shp, Water bodies, Headers
Departamentales_800, Rios_200, Roads, Routes
Asphalted_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.
Once deployed that the system allows to choose which layers we want to see and the order
Additionally, I recommend you take a look because there is much more to show in this project.
