Overview
VantagePoint contains a complete collection of spatial analysis tools that strictly conform to the Simple Features Specification for SQL published by the Open GIS Consortium.
Our spatial analysis tools provide several 2D spatial algorithms. (See below.)
Spatial Operations
Boundary — Creates a new feature that is the closure of the combinatorial boundary of the selected feature(s).
Buffer — Creates a new feature that represents all points whose distance from the selected feature(s) is less than or equal to the specified positive or negative distance. Calculations are in the Spatial Reference System of the map window.
ConvexHull — Creates a new feature that represents the convex hull of the selected feature(s).
Difference — Creates a new feature that represents the point set difference of the selected source features.
Distance — Calculates the shortest distance between any two points in the two selected source features as calculated in the spatial reference system of map window.
Intersection — Creates a new feature that represents the point set intersection of the selected source features.
SymmetricDifference — Creates a new feature that represents the point set symmetric difference of the selected source features.
Union — Creates a new feature that represents the point set union of the selected source features.
Spatial Relations
Contains — Highlights (selects) all features that are spatially contained by the map window area of interest.
Crosses — Highlights (selects) all features that spatially cross the map window area of interest.
Disjoint — Highlights (selects) all features that are spatially disjoint from the map window area of interest.
Equals — Highlights (selects) all features that are spatially equal to the map window area of interest.
Intersects — Highlights (selects) all features that spatially intersect the map window area of interest.
Overlaps — Highlights (selects) all features that spatially overlap the map window area of interest.
Touches — Highlights (selects) all features that spatially touch the map window area of interest.
Within — Highlights (selects) all features that are spatially within the map window area of interest.
