3.2. Quickstart tutorial¶
3.2.1. Quickstart tutorial for advanced users¶
NextGIS Web - is a server geographical information system (GIS), which allows to store and to edit geodata and to display maps in web browser. Also NextGIS Web can share geodata with other NextGIS software.
NextGIS Web has the following features:
Display of maps in web browser (different maps with different layers and styles)
Flexible access permissions management
Geodata could be loaded from PostGIS or imported from files in GIS formats ESRI Shape, GeoJSON or GeoTIFF
Vector data could be downloaded in the following formats: GeoJSON, CSV, ESRI Shape
Map styles could be imported from QGIS project or could be set manually
Could act as a client for WMS
User can add photos to records, change records attributes, with a support for a WFS-T protocol for editing.
Listed features are available through a REST API from external software
NextGIS Web - is an open source software (license GPL v2+, see GNU General Public License, version 2).
System requirements listed in section “Recommended hardware”.
3.2.2. Integration with other NextGIS software¶
To manage geodata in NextGIS Web you can use desktop application NextGIS Manager.
This software simplifies batch processing of data in NextGIS Web.
Mobile application NextGIS Mobile allows to upload geodata collected in the field directly to Web GIS in online or offline mode.
Several mobile devices could see data changes in a single layer.
3.2.3. Map creation¶
To create a vector layer from ESRI Shape follow these steps:
Compress a shapefile to a zip-archive
Create a vector layer using a zip-archive through administrator interface
Add a style to newly created vector layer
To create a vector layer from GeoJSON follow these steps:
Create a vector layer from GeoJSON file through administrator interface
Add a style to newly created vector layer
To create a vector layer from PostGIS follow these steps:
Add a PostGIS connection (user login and password are required for access to database)
Add layers from created connection
Create styles for added layers
To create a raster layer follow these steps:
Prepare a raster file to meet the requirements
Create a raster layer from a file through administrator interface
Add a style to raster layer
After layers are loaded they should be added to a web map in web map properties page. Then a link to web map could be opened in a web browser.
If there are many layers to add this operation will be easier performed with NextGIS Manager.
