Convex Hull

Generates the smallest convex polygon that completely encloses a selected set of geometries. This operation is useful for creating bounding areas, simplifying complex datasets, and performing spatial analysis. The resulting shape forms the minimal convex envelope around the input features, ensuring optimal coverage with minimal boundary length.

Envelope

Creates an envelope or bounding box for selected geometries. This refers to the smallest rectangular area that fully contains each object. It is commonly used to generalize shapes, define extents, or prepare spatial data for indexing, visualization, or spatial queries. The result is a simplified and standardized representation of the original geometry's outer limits.

Simplify

Reduces the number of vertices (nodes) to simplify polylines or polygons, optimizing geometry complexity while maintaining overall shape integrity. This function is useful for improving performance and visualization of spatial data by decreasing detail where appropriate. When working with adjacent polygons, caution is advised as simplification may create unintended intersections or holes. The tolerance parameter controls the maximum allowed deviation between the simplified geometry and the original.

Triangulation

The Triangulation from Points tool generates a mesh of interconnected triangles by connecting a given set of points. This process creates a network of triangles that can be used for surface modeling, terrain analysis, and interpolation of spatial data. The resulting triangular mesh provides a foundation for advanced GIS and CAD operations, ensuring accurate representation of complex spatial structures.

Vertex

The Vertex Extraction tool generates individual point features from the vertices of existing geometries. This function is useful for analyzing, editing, or exporting key coordinate points that define lines, polylines, or polygons.
