# Gisaf
|
|
|
|
*Gisaf* is a web based GIS (Geographical Information System) initially developed
|
|
for the CSR Geomatics unit in Auroville, India.
|
|
|
|
Its main audiences are local administrations which need a platform
|
|
to develop and maintain a geographical, topological and environmental data,
|
|
allow teams of surveyors to upload data and update the GIS in near real time,
|
|
and collect data from a wide range of sources.
|
|
|
|
Although it just works out of the box, it is primarily intended to be customized
|
|
and extended with the data, uses, needs.
|
|
|
|

|
|
|
|
- Layers defined with Python plugins or ANSI-standard categories
|
|
- Open source industry standard interfaces (PostGIS database, OGCAPI)
|
|
- Support of different geographical projections
|
|
- Integrated administration interface
|
|
- Export of data from standard formats (Geopackage, Shapefile)
|
|
- Import and update of data managed in a well defined workflow with "baskets"
|
|
- Acquisition of different kinds of surveyors' equipments, accuracies
|
|
- Robust mechanisms of identification of the data sources, survey times

|
|
- Customizable dashboards
|
|
- Customizable base maps (domain specific set of layers)
|
|
- Python and Jupyter integration: easy to interact with, add features, components,
|
|
explore data and conduct scientific research
|
|
- Plugin architecture: add functions with Python packages
|
|
- Free and open source
|
|
|
|
## Software stack
