Today I was in a cartographic production institution, of those who learned very well how to program with Avenue, the initial intention was to present alternatives to the formal disappearance of ArcView 3x and the limitation of moving to ArcGIS 9.
It would have been more complicated if they had been Geomedia users before whom the comparison it would have been more extensive, or that they had silver available and were in the possibility of acquiring ArcGIS or lower cost Manifold-type applications. In a few minutes of exposure they were satisfied with the benefits of GvSIG; now I summarize what I think has convinced you:
1 It looks so much like ArcView and AutoCAD
The fact that GvSIG has so much similarity with ArcView 3x in its interface based on views, tables and layouts has been decisive. Then see that the way to build data with a resemblance to AutoCAD, with sufficient editing commands has influenced; Of course we know that users of ArcView 3x criticized the difficulty to edit data accurately and the lack of topology.
2. It's free, or almost
The correct word is free to use, however the way you have visualized it is that to distribute it there is no need to buy a license. This institution developed some functionalities on Avenue, and they were considering the possibility of moving to ArcGIS 9, what happens is that for users of their applications it is difficult to acquire this type of license ... especially because they are low-income municipalities.
Of course, for this I am committed to giving you a GvSIG course called "GvSIG for ArcView users" ... I think it will be interesting.
Acquiring ArcGIS, ArcGIS Engine, ArcObjects, Gis Server and ArcSDE meant close to $ 57,000. Now they will only invest $ 2,000 in a Java course, $ 1,000 in a GvSIG course and $ 2,000 in the preparation of good manuals ... It is not free of course, but it will only cost $ 5,000 because they have programmers who manage Java and know with their eyes closed the use of ArcView.
3. Multi-system compatibility
When developed over Java, runs on Mac and Linux, it means they would stop suffering for the service pack that supports the system they were thinking of implementing.
For now the decision is made, they will only make a work plan that reflects the stage of training, development and implementation of the new version of their system. Best of all, they hope to systematize the experience to turn it into a publication.
So yes, ArcView users like GvSIG. Two months away Be testing, Is already producing results.
There I tell you how I'm doing.
