We will use ArcHydro to calculate the different whatersheds of a given territory. It is not only important to know the different steps to achieve the desired result, but also the assumptions we will be using. Indeed, they are not privative of ArcHydro, however they are the only ones available. Continuer la lecture de « ArcHydro: determination of the watersheds of a territory (1) »
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 temporal trends of the bins values, using the analysis of emerging hot spots. Continuer la lecture de « The spatial-temporal cube of ArcGis : 2- Hot and Cold Spots »
