Introduction

  • Objective of this section
    • To perform spatial queries among features of a Map using different spatial operations ("Standard" and "Professional" editions only)
  • Topics in this section
    • Base selection: features defining the base of the query ("Standard" and "Professional" editions only)
    • Spatial operations: diverse types of spatial operations and the Layer on which the operation is applied ("Standard" and "Professional" editions only)


What are Spatial queries? ("Standard" and "Professional" editions only)

Spatial queries are geometric operations that Spatial Manager Desktop™ can perform to help you locate Features that interfere with other Features under certain conditions. For example, as you can see in the next picture, to locate which points of a Layer are found within the polygons of another Layer


Simple 'Spatial query' sample


How can I define a Spatial query? ("Standard" and "Professional" editions only)

To define a Spatial query in Spatial Manager Desktop™, you need to define the base of the query first, by selecting the Features to operate, next you must select the "Spatial query" function, and then you choose a Layer to query and the type of operation to perform. When you select the Features to operate, you can select a full Layer if you want to perform an interference operation between two full Layers


'Spatial query' operations


Which are the types of operations for Spatial queries? ("Standard" and "Professional" editions only)

The list of operations that Spatial Manager Desktop™ can perform using Spatial queries is the following:

  • Intersects
  • Touches
  • Within
  • Contains
  • Disjoint
  • Overlaps
  • Crosses

To find out more about each operation, you can take a look at this document (pages 2-15 to 2-20): OpenGIS Simple Features Specification
