Description
-----------
Dataset created during BSc thesis work of Mees Rapp and Pepa van de Wouw. A 3-weekly bathymetry survey on Lake Weija (Accra, Ghana) has been performed using a CHIRPS2+ fish finder sonar device and Ardusimple ZED-F9P RTK set up. GIS analyses methods have been used to study the quality of resulting interpolated bathymetric maps as a function of the sampling density. The methods have been consolidated in a manual.

Content of this dataset
-----------------------

.gpkg files (3) containing raw measurements of depths (m) measured with a CHIRPS2+ fish finder sonar device and Ardusimple ZED-F9P RTK set up. The .gpkg files contain data accumulated over respectively 1, 2 and 3 weeks of surveying. Units of depth are in meters.

Files can be read with geopandas, location and depth are in the point geometries as x: longitude (deg.), y: latitude (deg.), z: depth (m). Axis direction of z is downwards (i.e. deepest points have the highest positive values).

.TIF files (GeoTIFF) created through TIN interpolation and regridding to ~10m resolution (0.000087 degrees) of all 3 .gpkg files
Units are in meters. Deepest points have the highest value.

All files can be directly read in QGIS.
