We haven’t been able to wait and we have to show you one of the (many) things that we are working on: Temporary data in gvSIG Desktop.
At the videos that are linked from this post firstly you can see how we allocate the temporary ability to a shapefile (about crimes in London city) with a field that doesn’t contain dates (it’s an alphanumerical field). From that point we can consult the data in a determined moment or temporary range. And we also can generate animations at the same View.
At the second video, the utility of these tools can be seen better with a heatmap legend.
Do you understand that we haven’t been able to avoid showing you this new functionality?
