We make extensive use of GIS in Sahana.

You are welcome to join our community to share data, best-practise & extend the tool further :)

== User Documentation ==
 * [wiki:ConfigurationGuidelines#MappingOptions Configuration Guidelines]
 * [wiki:UserGuidelines/GIS User Guidelines]
 * [wiki:UserGuidelines/GIS/Data User Guidelines - Data]

== Data ==
We provide a repository of data formatted to be easily imported into Sahana Eden:
 * [wiki:GIS/Data Data]

!OpenSteetMap has much Open Data which we can use as either Tiles (basemap) or Vector overlays:
 * [wiki:GIS/OpenStreetMap OpenStreetMap]

Aerial (including Satellite) Imagery can be used as a basemap:
 * [wiki:GIS/AerialImagery AerialImagery]

== Tools ==
We recommend these tools:
 * [http://gdal.org GDAL] - Convert between raster formats
 * [http://gdal.org/ogr OGR] - Convert between vector formats
 * [http://qgis.org Quantum GIS] - Preview datasets in a UI
 * [http://postgis.refractions.net PostGIS] - Spatial storage
 * [http://geoserver.org GeoServer] - WMS, WFS

Whilst the tools are common to both platforms, the installation steps are different:
 * [wiki:GIS/InstallationGuidelines/Linux Installation of GIS Tools on Linux]
 * [wiki:GIS/InstallationGuidelines/Windows Installation of GIS Tools on Windows]

== Coding ==
How to make use of the Mapping engine within other modules:
