[edit] 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)

[edit] 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


[edit] 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


[edit] 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
