Assets¶
This page describes the key files within the assets directory. Not all files are described.
assessment¶
The assessment directory contains files that are created by wildcat. Ursa uses the basins, segments, and outlets created by wildcat in order to create identify the location and amount of initialized debris-flow material.
basins.geojson: file containing geometries and other important details about the basins created by wildcat
outlets.geojson: file containing the locations of the outlets created by wildcat
segments.geojson: file containing the stream segments found by wildcat
atlas14¶
The atlas14 directory stores everything related to finding the recurrence relations for any given rainfall intensity, which gets displayed on the plots created by ursa.
downloads: directory containing folders for each recurrence interval that was downloaded from Atlas14, with each folder containing an .asc file which covers the entire US Southwest for its estimated rainfall intensity for the recurrence interval.
intensity: directory containing folders for each downloaded recurrence interval, with each folder containing both the clipped and the unclipped rainfall intensities after converting the values to mm/hr.
RI: directory containing geotif files that correspond to the projected recurrence intervals for rainstorms of a given intensity occurring across the clipped area.
compile¶
The compile directory contains a directory called dclaw that contains the Makefile, compiled executable (xdclaw), and standard input files for running simulations and plotting (setrun.py and setplot.py).
evt¶
The evt directory contains the file EVT.tif, which contains all of the vegetation data that is used by wildcat.
extent¶
The extent directory contains files relating to the extent of the fire perimeter and other files relating to the perimeter.
analysis.geojson: file that contains the shape of the buffered perimeter shape, dclaw will model runout that goes up to the borders of this file.
aoi.geojson: file that contains the shape for the area of interest, will be the bounding box of the perimeter if the user did not provide an area of interest.
epsg.txt: file containing the EPSG code of the area.
hectares.txt: file containing the area within the perimeter in hectares.
perimeter.geojson: file that contains the shape of the fire perimeter provided by the user, just in a GeoJSON format.
wgs84.geojson: file containing the same shape as analysis.geojson, just in a different projection.
parallel¶
The parallel directory contains files that represent the regions being used for the parallelization of the debris-flow simulations.
parallel.geojson contains the entirety of the regions.
parallel_clipped.geojson contains the regions after being clipped to the analysis region.
streams¶
The streams directory contains the file streams.geojson which contains the entirety of the data about where stream segments are, before being clipped to the analysis area.
topo¶
The topo directory contains all of the files related to the experiment area’s topography, in a variety of file formats and resolutions.
The tif and tt3 directories contain the topography files of the respective file format clipped to the bounding box of the region in the file name.
accumulation.tif: the upstream drainage area across the analysis extent.
merged_topo.tif: the topography across the analysis extent, this is the topography that is primarily used within ursa.
slope.tif: the slope across the area.
var¶
The var directory contains data about the buildings and roads in the area of the experiment.
buildings.geojson: contains data about all of the buildings pulled from OpenStreetMap, including building type and location.
roads.geojson: contains geometries of each road in the area, as well as types of roads (highway, residential, service, etc.).
wildcat¶
If ursa runs wildcat internally, it is run from within this directory.
Other Files¶
basemap.tif: basemap tile created during preprocess_basemap, used as the backdrop for all plots created after runout is simulated.
basin_info.csv: file containing information about basins created by wildcat, organized by basin ID and containing information about everything from area of the basin to data about the soil.
inflow_points.geojson file containing locations of inflow points, as well as their corresponding basins.
recurrence.yml: file created using the atlas14 data, stores the lower and upper quartile, geometric mean, and median of the recurrence interval for a given rainfall intensity across the region.
