Useful resources for your map project

You bring the map project, we have the resources. Rely on our list of trustable pages that help you convert files, geocode addresses etc.

This documentation is always evolving.

Convert Shapefiles to import them as GeoJSON or KML files: https://mapshaper.org/

Please note that your file should be in WGS84 coordinate system. Otherwise, Mapcreator will not be able to open it. You can convert your file in https://mapshaper.org/ if needed. To do this, navigate to Console and write ‘’proj wgs84’’ after $ symbol.

WGS84 comprises a standard coordinate frame for the Earth, a datum/reference ellipsoid for raw altitude data, and a gravitational equipotential surface (the geoid) that defines the nominal sea level. Mapcreator natively supports WGS84. 

Convert KML files with location markers (and additional information for interactivities) to XSLX files: https://mygeodata.cloud/converter/

Convert a locally stored image to a data URI: https://www.site24x7.com/tools/image-to-datauri.html. The generated link can be used to add the image to your popups. 

Add coordinates to spreadsheets with the Geocode by Awesome Table extension for Google Sheets. It automatically creates lat and long columns based on an address column.

Create a GeoJSON file: http://geojson.io/

Online linter: geojsonlint.com

Large GIS files can slow down the performance. To avoid this, you can reduce the size of your file. Import your file to https://mapshaper.org/ and select the Simplify function. Simplify your file as much as possible while keeping it visually accurate for your needs.
