Geomap Geobide Beta 3 looks promising

Geomap is a new stage of development of what we knew as Tcmap, already under a concept integrated to the Geobide strategy of the company Tracsa. Like gvSIG, this initiative will interest me because it is born out of the Hispanic environment, with a proprietary approach but with prices within reach and under a staggered model that looks attractive.

Some time ago something was seen at the SIG Libre Girona Conference and just a year ago the launch of the suite was announced. It is not announced as a SIG solution but as a geographical data manager that is operated with different CAD platforms. CHALK.

In future articles we will see other tools Geobide, now I want to focus on Geomap that although Beta 3.0 is that, I took the time to test it because it looks promising as a free tool for deployment of geographic data. It constitutes the viewer -Although it does something more- within the modular scheme of the line that -Outside the SDK- includes analysis, construction and maintenance of data in 6 tools:

    • Geobuilder. With this you can build geoprocessing diagrams, the style is quite friendly and similar to the way it was popularized with ESRI.Geobide
    • Geoconveter. This is an astral smoked, but practical to transform massive data between different formats; Supports more than 20.

To put an example, in case carried out, they converted a total of 115 XYZ files in ERTS89 (16 GB with more than 503 million points and around 5 meters resolution) to a raster in BIL format in ED50.
This was done in 7 hours, this whole process with all the data at once, not sheet by sheet. The application executes the triangulation of the information with an algorithm called "streaming
Of one and
"Which allows managing huge volumes of data between what it included:

- Transformation of 115 files XYZ ETRS89 to 115 files LAS ED50 (Time
~ 2: 30 hours).
- Transformation of LAS files to a single raster file in BIL format with a pixel size of 5 meters. (Time ~ 4: 20 in hours).

In this last step all points (> 503 million) are triangulated in a TIN and a single GRID of the entire working area is generated as output.

    • Geobridge. This allows you to work with commonly used program formats, such as AutoCAD, Microstation or ArcGIS files without having to convert them to another format. Most surprisingly, the approach they have had with the V8 format with which many others have fallen short.
    • Geocheck. These are tools that facilitate data consistency in terms of topological cleanliness and spatial validation rules.
    • Geotools. This has advanced tools that can be activated or deactivated towards other interfaces.

In the case of Geomap, the current beta still thunders to some processes. But in what I've been trying I found some features interesting.

Geobide Of the best, and a feature of the complete suite is the Format support, including Geomedia, ESRI, Lidar, PostgreSQL, kml, gml, Oracle, WFS, MySQL, including DGN V8 formats from Microstation.

But Geomap is much more than a viewer. It is valuable that apart from opening a file, you can export it to another format, allowing you to configure properties such as:

  • In the case of point files, choose the order xyz and number of decimals.
  • In the case of dwg / dxf files, choose whether to unbundle blocks and handle curves.
  • In the case of dgn files, you can choose to run some processes using the installed Microstation engine, indicating where the ustation.exe file is; generally for offline commands when converting to v7 format in the handling of cells and texts. You can also choose shipping to v7, v8, seed 2d, 3D and also select an existing dgn as seed.
  • To export, there are also special configurations like the format type in dgn, dwg ... files, well, very good.

In terms of deployment, Geomap lets you load different views of Google Maps, Bing, Yahoo, Open Street Maps and even Esri Imagery Map and Esri Imagery Street. These can be placed in synchrony with a vector layer so that when approaching an area, so do the other displays. Each layer has its properties, where you can define parameters like Asynchronous stream, So that the load becomes more efficient.


You can load layers coming from a WMS server Tailed, being able to establish alternatives of cache and re projection system to the flight. For DEM layers you can choose the theming or import it from a .bil / .bt file

The file is saved in a .mwd format that is similar to the ESRI mxd.


You have to see it to judge it, but it has tools that are notorious born of innovation. Like going to a specific coordinate, in which it is possible to choose a specific reference system and scale of deployment.


In conclusion, it looks promising as a free data viewer. As it caught my attention TatukGIS, It seems that this could be that tool we use to view and transform data lightly, or compare against layers of web maps.

Although the 2.0 version is fully functional, I'm waiting for a stable version of this 3.0; There is work to do in repairing a series of bugs normal in beta versions. Apparently with the GDI running the base map could be exported, pro now launches a blasphemous error. Then we would have to see what capacity the geoprocessing manager shows, which seems to allow creating and saving geoprocesses in .gpf format.

The help is also short, as there are no manuals available yet.
