GIS Visualizer is a free web application for geographic data visualization. With it's intuitive GUI, it provides an easy way to visualize vector data on 40+ base maps and supports most popular vector formats: GeoJSON, GPX, IGC, KML, Shapefile, TopoJSON, WKT, etc.
Especially, it supports the unique POINTS format: just simply a set of points, no any data structure required at all!
There are four ways to import vector data: File, URL, Text, and Drag-and-Drop - simply drag and drop GeoJSON, GPX, IGC, KML, or TopoJSON files on to the map.
You can export any vector layers as one of the 4 formats: GeoJSON, KML, WKT and GPX. This functionality can be used as vector format converter.
There are 3 ways to style a layer: use the Default style, pick a Random style, or build your own Custom style.
