Understanding Multi-Layer GeoJSON Viewer
Features, layers and visual encoding
Open several GeoJSON location layers together, control their visibility, and inspect their features on a private browser map.
Multi-Layer GeoJSON Viewer turns spatial features into a map layer. Geometry controls placement; properties can control labels, categories, symbol size or other visual choices without changing the source records.
How to read the map
GeoJSON layers must use WGS84 longitude and latitude. Add one or several local files; no workspace state is saved.
Use Multi-Layer GeoJSON Viewer to inspect patterns and obvious placement problems, then verify important records and properties directly. Display scale, zoom and styling can hide overlap or make small differences look more significant.
