SuperGIS Desktop, some comparisons ...

SuperGIS is part of the model Supergeo of which I spoke a few days ago, with good success in the Asian continent. After being tested, here are some of the impressions that I have taken.

In general, it does almost what any other program of the competition does. It can only run on Windows, it is possibly developed on C ++, so it is running at a very good speed; although this brings you the disadvantage of not being multiplatform ... a problem that very few others have solved by the way.

In terms of appearance, it looks a lot like ESRI's ArcGIS, with floating and dockable frames, layer grouping, drag and drop. Moreover, the logic of construction and scalability is very marked to keep competing with this model; what can be observed in its main extensions:

Spatial Analyst, Network, Topology, Spatial Stadystical, 3D, Biodiversity Analyst.

Additionally it is complemented with the applications included in the desktop version: SuperGIS Data Manager, equivalent to ArcCatalog and SuperGIS Converter, equivalent to ArcToolbox.

The logic of project construction is in traditional xml files, with .sgd extension that act as an .mxd / .apr file in ArcGIS or a gvSIG .gvp file. There is no extension to import a project from another GIS program and although this logic is oriented on how the IMS publication will read the projects, it also supports data within Personal (mdb), MS SQL Server, Oracle Spatial and PostgreSQL Server geodatabase.

The .sgd format has had two major changes; The current one since the version 3.1a imports the previous one of the version 3.0.

Supported Formats

In vector format:

  • GEO (edition)
  • SHP (edition)
  • MIF / MID
  • DXF
  • GML
  • DWG, up to 2013 versions
  • DGN v7, v8

Everything seems very common to what other tools do, although here it stands out that the vector formats dwg, dgn, dxf recognizes recent versions.

I do not know how they will have achieved it, but it is one of the weaknesses of Manifold GIS, gvSIG and other open source software. In the case of a dgn / dwg file, it allows you to thematize it, turn it off, turn it on, even if only by layer (level), even if it is only loaded as a reference; to edit it you have to export it to .geo format or .shp. It is interesting to clarify that the .geo format only supports polygon, polyline and point; the multipoint is only supported by the .shp when creating a new layer.

Read microstation dgn in 8 and dwg version of AutoCAD in 2013 version ... it deserves a merit. Although it surpasses gvSIG, it can edit dwg, dxf and kml, while SuperGIS can only edit shp and its own extension format .geo. Another vector proprietary format is .slr (Supergeo Layer File), with which you can work on tablets using SuperSurv, and also from the desktop client.

From SuperGIS Data Converter you can make conversions between the previous formats, also including the formats kml (Google Earth), e00 (ArcInfo), sef (Standar Exchange Format).

In raster format:

  • SGR, which is a proprietary SuperGIS format
  • MrSID
  • GeoTIFF
  • BMP, PNG, GIF, JPG, JPG2000
  • ECW
  • LAN
  • GIS

The .sgr format is proprietary to Supergeo; With this it runs at an impressive speed both the deployment and the specialized treatment with Image Analyst.

Cad gis tools

It has a disadvantage that it does not read ENVI, SPOT files that are supported by programs such as Manifold GIS and gvSIG. The capabilities of georeferencing images is quite common to what gvSIG / ArcGIS does.

From SuperGIS Data Converter you can make conversions between the formats img, gis, lan (Erdas), tif, ecw, sid, jpg, bmp, and ASCII txt.

In OGC standards

  • WMS (Web map service)
  • WFS (Web feature service)
  • WCS (Web coverage service)
  • WMTS. This is the format for handling mosaic data (Tiles)

OGC Client, GPS, Geodatabase Client, SuperGIS Server Desktop Client and Image Server Desktop Client are added to this and other functionalities.

The case of the kmz format only supports it with the extension 3D Analyst. In the case of network formats, the .geo supports them, being able to import using DataConverter from shape files, as well as digital terrain data that can be imported from shape files and sgr.

Editing capability

I have always been struck by this aspect, which in general requires us to use a CAD program to build data and a GIS already when these are worked. It is an important advance that Have had gvSIG And Quantum GIS in this regard, including additional packages such as the case OpenCAD tools With which we should no longer complain.

In the case of SuperGIS, it allows the edition of one or more layers, in the traditional style. Those with extension .geo and .shp are shown, you can save and stop editing. Additionally, in the same tab there are common edition uses among those that match the gvSIG palette:

Let's look at a comparison of the CAD tools that have AutoCAD, gvSIG and SuperGIS, taking into account my old list of preferred AutoCAD commands.

No. Command AutoCAD GvSIG SuperGIS
1 Line Autocad gvsig commands Autocad gvsig commands Cad gis tools
2 Polyline Autocad gvsig commands Autocad gvsig commands Cad gis tools
3 Circle Autocad gvsig commands Autocad gvsig commands Cad gis tools
4 Autocomplete Autocad gvsig commands Autocad gvsig commands Cad gis tools
5 Link Autocad gvsig commands Autocad gvsig commands image
6 Autocad gvsig commands image
7 Trim Autocad gvsig commands Autocad gvsig commands Cad gis tools
8 Copy Autocad gvsig commands Autocad gvsig commands Cad gis tools

14 Exploit Autocad gvsig commands Autocad gvsig commands Cad gis tools
15 Sweaters, Jerseys and Cardigans Autocad gvsig commands Autocad gvsig commands Cad gis tools
16 bow Autocad gvsig commands Autocad gvsig commands Cad gis tools
17 Polygon Autocad gvsig commands Autocad gvsig commands
18 Ellipse Autocad gvsig commands Autocad gvsig commands
19 Hole Autocad gvsig commands Autocad gvsig commands Cad gis tools
20 Rectangle Autocad gvsig commands Autocad gvsig commands Cad gis tools
21 To stretch Autocad gvsig commands Autocad gvsig commands image
22 Multipoint Autocad gvsig commands
23 Parallel Autocad gvsig commands image
24 Extender Autocad gvsig commands Cad gis tools
The first 14 (1 to 14) were on my list of 25 most used commands. Some of them are not exactly the equivalent, like: -bind / make block
-autopolygon / boundaryHere, it is striking that SuperGIS in a single command groups more than one, which appear in a contextual way, such as the case of "Sketch" that includes line, polyline, point and multipoint.

The edit geometry command groups vertex editing, stretching, proportional scaling.

There are no commands that we used in CAD, such as Array, regular polygon, ellipse. In practice they are not so urgent although gvSIG integrated them as part of doing what was important in CAD.

They excel Extend and Copy in parallel. Also the move command that allows you to enter a destination coordinate.

imageThe functionality seems practical, gives the impression that SuperGIS came to this with a lot of practical work with real users. In the case of precision, there are snap options for midpoint, intersection and nearest point. While it can also be configured if it is applied to edges or vertices with a specific tolerance and per layer.

Cad gis toolsFloating windows are raised with the commands; Can be created from coordinates, distance / heading, distance / distance ... although in some I found something strange the functionality ... requires practice as a new tool.

Additionally, commands are required that are required for GIS processes, which were not of much interest in CAD, such as:

Segment (split), Segment in vertex, Generalize, Smoothen (smooth), very common for GIS work. In addition to the common geoprocessing processes that are almost a Copy / paste of what we already know.

At the level of layouts for printing, I will approach it in a following article; since I have my reservations and I would wait for then to have the multiframes development that are working in which I proposed the possibility of saving theming states, in order to be able to load in the same layout different dataframes. I have been promised to have this for the SuperGIS Desktop 3.1b version in the third quarter of 2013; similar to what CadCorp or Manifold GIS does.


In conclusion, it seems a fairly robust tool at the desktop GIS level.

For those who want to try it,
