NextGIS Web is an open source Web GIS server: store geospatial data, publish it as interactive web maps, and share it with desktop GIS clients over standard OGC services.
NextGIS Web is a Web GIS server from NextGIS. You upload vector and raster data, style it, and assemble web maps that render in the browser with a layer tree, feature identification, attribute tables and search. The same data is served as standard OGC endpoints, WMS and WFS, so desktop GIS clients such as QGIS and ArcGIS read straight from the server. Everything lives in one PostgreSQL and PostGIS database plus a file store, so the resource tree, users, permissions and geometry sit together in a single system you administer.
It suits organisations that need to collect, manage and publish spatial data from one place: local and regional government, utilities, surveying and engineering consultancies, and environmental and land management teams that want internal staff, external partners or the public to see the same authoritative maps.
Standing up NextGIS Web means assembling a Pyramid application, a PostGIS database, a web tier and the GDAL stack it renders through, then wiring them together and proving they work. cloudimg ships that whole stack assembled and proven, with a demo web map that renders an actual map the first time you sign in rather than an empty page you have to populate before you can tell it works. Security is designed in: the built in administrator password is generated uniquely on first boot, never shipped as a default, and the database is reachable only from the machine itself. Your geospatial data sits on a dedicated data volume, a written deploy guide walks you through launch and first sign in, and every image is backed by 24/7 support.
