New open source geospatial software stack introduced by NextGIS including NextGIS Web (server backend and web interface), NextGIS Mobile (mobile app), NextGIS QGIS (desktop GIS), and NextGIS Manager (data management). The components provide functionality for data storage, management, access, visualization, editing, and integration across server, desktop, and mobile environments using open standards and open source technologies like Python, C++, PostGIS, and OpenLayers. NextGIS aims to create an integrated platform for working with geospatial data in all environments.

● /api/resource/{id}/feature/ GET,POST
● /api/resource/{id} GET,PUT,DELETE
● /api/resource/{id}/permission GET
