This workshop builds on new opportunities provided by the increasing availability of free satellite imagery, digital elevation data, and open source spatial analysis software through the use of SAGA-GIS for sophisticated natural resource mapping and modeling. The ease of installation and immediate access to advanced raster tools for remote sensing, terrain, and hydrology analysis makes SAGA GIS a powerful addition to your FOSS toolkit.
The aim of this training is to provide a basic overview functions within SAGA-GIS software that enable applications in two areas key to evidence-based natural resource management; (1) satellite-based mapping and monitoring and (2) terrain analysis and hydrological modeling. Training will be based on real-world examples of simple techniques for practical management application and cover:
- Accessing and visualising Landsat, Sentinel-2 and elevation data
- 3D Landscape visualisation
- Basic terrain modelling and hydrological analysis with free elevation data
- Applications for forest fire and mine monitoring.
The workshop will be supported by, and provide an introduction to, comprehensive online training material (sagatutorials.wordpress.com). The workshop convenor has led the development of integrated digital training content in English and Indonesian that is now being used around the world as the go-to reference for SAGA-GIS. This material is now being extended into Latin America with the development of Spanish language content.
SAGA-GIS is developed by users for users and is constantly updated with cutting-edge geospatial research. Currently SAGA offers more than 700 geo-scientific modules supporting a range of scientific questions and NRM needs. SAGA GIS has the following key features:
- Simple, onestep, processes for sophisticated hydrological and terrain modelling
- Simple process for satellite data visualisation.
- Advanced image classification techniques
- Seamless integration of satellite image and terrain analysis tools.
- A compact package that does not require installation and is thus is easy to use and share
