QGIS is a professional GIS application that is built on top of and proud to be itself Free and Open Source Software (FOSS).


GeoNode is a web-based application and platform for developing geospatial information systems (GIS) and for deploying spatial data infrastructures (SDI).


PostgreSQL is an open source relational database, that has been developed more that 15 years. It is used widely in very large and demanding environments. When used with PostGIS extension, it is very efficient storage and analyze tool for geospatial data.


GeoServer is a Java-based open source server software that allows users to share and edit geospatial data. GeoServer supports all major data sources as well as open OGC standards. GeoServer is widely used and proven to operate well in many complex and high availability geographic information system.


OGC (Open Geospatial Consortium) is an organization that has defined a number of open standards for GIS domain. Usually open source GIS applications are based on open standards defined by OGC and that makes them compatible with each other as well as easily extendable. GIS systems developed by Arbonaut are typically based on OGC standards.


MapServer is very efficient and light-weight open source server software for publishing geospatial data. MapServer offers the most important OGC interfaces like WMS, WFS, WMC, WCS, Filter Encoding, SLD, GML, SOS, OM. Through GDAL library, MapServer supports a large number of different spatial data formats. MapServer project is supported by OSGeo.


OpenLayers is an open source javascript component to display a dynamic map in a web browser. OpenLayers supports a large number of different vector and raster formats as well as tiled map viewing. As a pure Javascript implementation, OpenLayers works well in all major browsers as well as in mobile devices and does not require any plugins.


GDAL (Geospatial Data Abstraction Library) is widely used open source library for geospatial data conversions. GDAL supports more than 120 different data formats. GDAL is published by OSGeo (Open Source Geospatial Foundation).


uDig (User-friendly Desktop Internet GIS) is a desktop GIS application efficiently enabling simultaneous usage of many spatial datasets. Application is based on Java technology and Eclipse framework and follows standard interfaces defined by OGC. Because uDig is an open source application, it is fully customizable and extendable and that makes it perfect platform for any custom GIS application. In uDig gallery you can find one of Arbonaut’s uDig based GIS applications.


GeoTools is an OSGeo project and an open source Java library offering tools for handling geospatial data in java-based applications.


OsGeo (Open Source Geospatial Foundation) is a non-profit organization that supports collaborative development of open source geospatial software. Many of applications listed above are supported by OsGeo.
