Introduction
- Objective of this section
- To perform spatial queries among features of a map using different spatial operations
- Topics in this section
- Base selection: features defining the base of the query
- Spatial operations: diverse types of spatial operations and the layer on which the operation is applied
What are Spatial queries in Spatial Manager Desktop™?
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 in Spatial Manager Desktop™?
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 select 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 in Spatial Manager Desktop™?
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
