Selecting a Spatial Relationship for Feature Classification

About Selecting Spatial Relationships

Points can be classified based on two spatial relationships to feature geometry:

• Within a Distance of: points that are within a distance of a specified amount are determined to satisfy the relationship. The distance to feature geometry is calculated as an euclidean distance from the point to the closest point on the input geometry.
• 
  
  
• Completely Within: points that are completely within or contained by the polygon geometry are determined to satisfy the relationship

All spatial relationships cannot be available for all types of geometry. The "Within a Distance of" relationship can be used for point, line, and polygon geometry types. When using the "Within a Distance of" operator with polygons, points within or contained by the area are considered to be zero distance from the geometry. The "Completely Within" relationship is only used with polygon geometry.

How to Select a Spatial Relationship

1. Click within the Spatial Relationship column for the type value you wish to assign a spatial relationship.
   
   
   
2. Select a spatial relationship from the list.

Tip When using the "Within a Distance Of" relationship with polygonal features, all points within a polygon are considered to be zero distance from the feature.
