This chapter introduces the foundations of data analysis in the context of query. It explains how data are queried and extracted within Geographic Information Systems (GIS). Attribute and topological query operations are also introduced. Spatial query refers to the process of retrieving a data subset...
Creates a spatial query which performs a spatial search for features in the supplied feature class and has the option to also apply an attribute query via a where clause. ///Creates a spatial query which performs a spatial search for features in the supplied feature class and has the option ...

Depending on the spatial join type, it can affix one or several features into the target layer. In this case, you have to pick a “Join” operation that includes one-to-one or one-to-many. Operations for Joining Features Let’s say you have multiple features that you want to combine i...

Spatial autocorrelation in GIS helps understand the degreeto which one object is similar to other nearby objects. Moran’s I (Index) measures spatial autocorrelation. Geographer Waldo R. Tobler stated in thefirst law of geography: “Everything is related to everything else, but near things are ...
