Cartography

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

The practical sessions will apply the concepts covered in the course (reading and interpretation of satellite images, geological section). Practical work will be devoted to mapping the northern region of the Pic St Loup, by reading and interpreting satellite images, then checking this interpretation and taking measurements in the field, and finally returning to GIS to finalize the work.

Hourly volumes :

CM: 6h

TD : 6h

Practical work: 12h

Field : 12h

The aim of this module is to acquire the basic skills required for digital cartography using Geographic Information Systems (GIS) and geological mapping. These skills will be taught using the example of a^1st-order geological map of the northern Pic St Loup region.

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

Recommended prerequisites :

Hiking with a map, having already used Géoportail and Google Earth.

Continuous control

• Synthetic description of the concepts covered in CM :

See EU description

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

2 x 3-hour sessions, one dedicated to reading and interpreting satellite images, the other to geological cross-sections

• Summary description of practical sessions and number of hours for each session

4 sessions of 3 hours:

-measurements of inclination and positioning on campus (compass, GPS, smartphone app) and transfer to map with QGIS software

-interpretation of satellite images of the northern part of the Pic St Loup and preparation of the field trip, the aim being to optimize the limited amount of land available to us.

-The last 2 sessions will follow the field trip, and will be devoted to familiarizing ourselves with QGIS software by creating a geological map of the area under study.

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

Verification of satellite image interpretations, correction of interpretations and dip measurements

Basic skills needed to produce a geological map from field to finished product (digital map, instructions, section and log)
