Mapping

The lectures will cover concepts of cartography (projection systems, height reference systems, positioning), imaging (aerial, satellite, digital encoding, DTM), field measurements (positioning, stratum dip), construction of a geological cross-section and stratigraphic log, and Geographic Information Systems (GIS, georeferencing, QGIS software).

The tutorials will apply the concepts covered in the lectures (reading and interpreting satellite images, geological cross-sections). The practicals will focus on mapping the northern region of 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: 6 hours

Tutorial: 6 hours

Practical work: 12 hours

Field: 12 hours

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

Basic concepts in cartography (projection, coordinate systems, reading contour lines) and geology (what is a geological cross-section, dip)

Recommended prerequisites:

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

Continuous assessment

• Brief description of the concepts covered in CM:

See description of the EU

• Brief description of tutorial sessions and number of hours associated with each session

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

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

4 sessions of 3 hours:

-measurements of dip and positioning on campus (compass, GPS, smartphone app) and reporting on a map using QGIS software

-interpretation of satellite images of the northern area of Pic St Loup and preparation for the field trip, the aim being to optimize the limited terrain available to us

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

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

Checking interpretations made on satellite images, correcting these interpretations, and measuring dip angles

Basic skills required to produce a geological map of the terrain, from start to finish (digital map, notes, cross-section, and log)

Fundamentals of digital mapping (GIS)
