GIS coaching for territorial management.
Thanks to the SRTM project we can access to a comprehensive world coverage of land elevation data. It has become very simple to create one’s own topographic maps with QGis . We will discuss here : Download elevation Data To download the elevation data of your area of interest , go on page http://viewfinderpanoramas.org/dem3.html This video shows you the progress of the download . The data available corresponds…

In the previous article (Le Cube spatio-temporel d’ArcGis : 1- découverte) we discussed how to create a spatial-temporal cube from a cloud of XYZ points. The points are grouped into ” boxes ” (bins) corresponding to 3D pixels. We have discussed how to depict them in an ArcGis Pro 3D scene. In this article we will discuss how to analyze the…

One of the domains of GIS where still remains a lot to be done is the field of temporal analysis . While almost all the available tools focus on the spatial evolution of a phenomenon, we are left helpless when trying to visualize or analyse a phenomenon that changes as a function of time as well. For some time, we have…
