Overview

The Simplify gem reduces the number of vertices in polygons and polylines while preserving their overall shape. This is useful for reducing file sizes, improving rendering performance, and simplifying complex geometries for analysis or visualization. The gem uses the Ramer-Douglas-Peucker algorithm, which removes vertices based on their perpendicular distance from line segments. You can control the level of simplification by adjusting the distance threshold.
The gem has a corresponding interactive gem example. See Interactive gem examples to learn how to run sample pipelines for this and other gems.

​
Prerequisites

  • Add ProphecyDatabricksSqlSpatial version 0.0.4 or higher to your project.

​
Input and Output

The Simplify gem accepts the following input and output.
Input geometries must be in WKT format. Use the PolyBuild gem to convert longitude and latitude coordinates into polygons or polylines in WKT format.
