The Sediment Thickness Model for Andalusia (STMA) data, intermediate data and scripts

This dataset contains the Sediment Thickness Model for Andalusia (South of Spain), the GroundHog files and the consulting scripts linked to the paper "Thickness model of Andalusian's nearshore and coastal inland topography " under review in Journal of Marine Science and Engineering.

The following ZIP files can be found here:

===============
STMA.zip

A dataset of 108 ESRI ASCII grid files group by province (Almeria, Cadiz, Granada, Huelva and Malaga) and by physiographic zone (18). Each zone has six different files named as:

PZZ_V_T_S.asc

where,

P: It is the first letter of the province (e.g. A for Almeria, C for Cadiz…)

ZZ: number of physiographic zone from a minimum number of 2 to 6 in each province. Each province was divided by different overlapping rectangles following on the orientation of the coastline, the shape of the continental shelf, river intersections, capes, the main sediment type, and the level of influence from atmospheric and maritime weathering agents, primarily.

V: the model version

T: Type of sediment, Consolidated (C) and Unconsolidated (U)

S: Grain size, Fine (F), Sand (S) and Gravel (G)

e.g. the file A01_1_C_F.asc is the province of Almeria, zone 01, version 1, Consolidated sediment and Fine fraction.

All files have a projection file (EPSG 25830) with the same name but a *.prj extension and a auxiliary file (*.asc.aux.xml) with additional information about the projection used. 

===============
Script.zip

Specifically, three Pyqgis scripts and three Model Qgis: 

• 1_Add_STMA_by_province_and_zone.py: to add the STMA to QGIS grouping the layers by province and zones.
• 2_Point_value_STMA.py: to add the STMA value to a point sample layer.
• 3_Zonal_statistics_STMA.py: to calculate the zonal statistics of STMA in a polygon area.
• 1_Volume_STMA.model3: Calculate the volume of each material (six raster layer) in one zone.
• 2_Volume_STMA_Clip.model3: Calculate the volume of each material in a clip area using a polygon layer.
• 3_Zonal_statistics_STMA.model3: Zonal statistics of the STMA in a polygon layer. It is a model version of the last pyqgis script 3_Zonal_statistics_STMA.py.

The first two models could be used in a batch processing if the user needs information of more than one zone.

===============
GroundHog.zip

Five folders, one for each province, with information to open the models in Groundhog software.
