Environmental Impact Calculator - Version 1X

Calculate and visualize multiple environmental impacts (Layers) from multiple study areas (Impact Shapes) without the need for GIS software. Designed for the transportation industry. Built using turf.js by SteveCline.

Impact layers support all geometry types, but multi-point features will be exploded and counted as single points. All impact shapes must be a single polygon or single multi-part polygon.
