1.4. 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).
If you are uploading through Web interface pay attention that uploaded vector layers don’t include mixed or invalid geometries and attribute columns are not named id (ID). These limitations don’t apply if you’re uploading with NextGIS Connect <ngqgis_connect>.
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.
