4.2. Quickstart tutorial

4.2.1. 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 server for TMS, WMS, WFS

• 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”.

4.2.2. 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.

4.2.3. Map creation

To create a vector layer from ESRI Shape follow these steps:

1. Compress a shapefile to a zip-archive

2. Create a vector layer using a zip-archive through administrator interface

3. Add a style to newly created vector layer

To create a vector layer from GeoJSON follow these steps:

1. Create a vector layer from GeoJSON file through administrator interface

2. Add a style to newly created vector layer

To create a vector layer from PostGIS follow these steps:

1. Add a PostGIS connection (user login and password are required for access to database)

2. Add layers from created connection

3. Create styles for added layers

To create a raster layer follow these steps:

1. Prepare a raster file to meet the requirements

2. Create a raster layer from a file through administrator interface

3. 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.
