Geographic Information Systems

The teaching is carried out in the form of 3 sequences.

Sequence 1 : Preparing a naturalist expertise on GIS

At the end of the sequence, learners will be able to display and convert the main types of GIS data and plan a field survey with handheld GPS units.

Different types of data (vector / raster data), most common formats QGIS interface, use of Qgis

Symbology on discrete and continuous variables (on vector and raster)

Coordinate systems and conversion from one system to another

GPS data acquisition and map layout

-Layer creation and digitization

3 sessions of 3 hours

At the end of sequence 1, the students will have to carry out a mapping exercise (which will be used for the evaluation). The students in initial training will carry out this work in groups from the workshop-sites (estimated time of 3 hours of non-attendance). The alternating students will do it in the framework of their professional activity.

Sequence 2 : use and management of databases

Database design; interest, software...

database query, SQL language

Creation of tables, basic SQL queries

2 sessions of 3 hours

Sequence 3: Spatial data analysis

At the end of the sequence, learners will be able to perform simple queries and simple geoprocessing.

Calculation of QGIS fields, use of mathematical and geometrical functions, calculation of surfaces and lengths.

Spatial queries and Geoprocessing

Home ranges and habitat selection

2 sessions of 3 hours

- Make the student autonomous in the use of GPS and GIS in order to master the whole chain from data collection to exploitation

Understand the organization of databases and queries to query databases

Train the student to use open source GIS (QuantumGIS) to use spatialized data, mapping.
