- A shape file of the 'sub-areas' of the hotspot. Ideally sub-areas are created such that hazards within are similar. It is not necessary (or very desirable) to divide the hotspot such that each area contains (almost) only one receptor type.
- A shape file of the units of the receptor of interest. A unit could be a house, but also a road section. Note: units cannot be split across areas, but must be uniquely assigned to a single area.
- A hazard.nc file (can be a dummy simulation, as long as it contains the proper grid information)
All three files need to be in use the same projectioncoordinate system.
Creating a FEWS_grid.txt
Before importing the grid to QGIS, a unique gridID needs to be associated to every single grid point. It is important to do that beforehand, because the ordering of grid points may change while importing. To do so the first section (%% Add a unique gridID to your FEWS grid and save as csv file to be processed in QGIS) of this matlab script can be used: code_for_receptor_txt_files.m
