Mapping

The lectures will cover the notions of cartography (projection system, reference frame for heights, positioning), imagery (aerial, satellite, digital encoding, DTM), field measurements (positioning, dip of a stratum), construction of a geological section and a stratigraphic log and Geographic Information Systems (GIS, georeferencing, QGIS software).

The TD will apply the notions of the course (reading and interpretation of satellite images, geological section). The practical work will be devoted to the establishment of the map of the northern region of the Pic St Loup, by reading and interpreting satellite images, then the control of this interpretation and the taking of measurements on the ground and finally the return on GIS to finalize the work.

Hourly volumes:

CM : 6h

TD : 6h

TP : 12h

Field : 12h

The objective of this module is to acquire the basic skills necessary for digital mapping under Geographic Information System (GIS) and geological mapping. It is through the example of the establishment of a^1st order geological map in the northern region of Pic St Loup that these skills will be taught.

Basic cartography (projection, coordinate system, reading contour lines) and geology (what is a geological section, a dip)

Recommended prerequisites:

Hike with a map, have already used Geoportal and Google Earth.

Continuous control

• Synthetic description of the concepts covered in CM:

See EU description

• Synthetic description of the TD sessions and number of hours associated with each session

2 sessions of 3 hours, one dedicated to the reading and interpretation of satellite images, the other dedicated to geological sections

• Synthetic description of the practical sessions and number of hours associated with each session

4 sessions of 3 hours:

-Measurements of inclination and positioning on the campus (compass, GPS, smartphone application) and transfer to a map with QGIS software

-Interpretation of satellite images of the northern area of the Pic St Loup and preparation of the field trip, the goal is to optimize the little land we are allowed

-The last two sessions will follow the field trip and will be devoted to learning how to use QGIS software by creating a geological map of the area studied.

• Description of the themes/manipulations addressed during your field trip(s) and details of the destinations/sites

Control of the interpretations made on the satellite images, correction of these interpretations and measurements of dip
