Introduction
- Objective of this section
- To perform spatial queries among features of a Map using different spatial operations (not in "Basic" edition)
- Topics in this section
- Base selection: features defining the base of the query (not in "Basic" edition)
- Spatial operations: diverse types of spatial operations and the Layer on which the operation is applied (not in "Basic" edition)
What are Spatial queries? (not in "Basic" edition)
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
How can I define a Spatial query? (not in "Basic" edition)
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
Which are the types of operations for Spatial queries? (not in "Basic" edition)
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
