1.3. Which data formats and protocols are supported in Web GIS

Web GIS allows to upload and store geodata from local sources in the following spatial data formats:

  • Raster - GeoTIFF (with 3 or 4 bands, RGB or RGBA);
  • Vector - ESRI Shape (zip-archived, UTF-8 or Windows-1251) and GeoJSON (UTF-8).

Warning

Uploaded vector files can’t inculde mixed or invalid geometries, dates can’t have NULL values, attributes’ columns can’t have the following names: id (ID), type (TYPE), source (SOURCE). ESRI Shapefiles can’t include multigeometries.

Web GIS also allows to connect geodata from the following external sources:

You can add images (including photos) to vector geodata from local and external sources. Image files should be in JPEG or PNG format. Read more here.

You can also publish uploaded or connected to your Web GIS geodata using WFS (with feature update support) and WMS protocols. Read more here.

Vector geodata from local and external sources can be exported as GeoJSON and CSV files. Read more here.
