1.3. Which data formats and protocols are supported in Web GIS¶
- Raster - GeoTIFF (with 3 or 4 bands, RGB or RGBA);
- Vector - ESRI Shape (zip-archived, UTF-8 or Windows-1251) and GeoJSON (UTF-8).
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:
- TMS services;
- PostGIS databases;
- WMS services (WMS server should support coordinate system EPSG:3857).
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.
