plot_vs30_map

plot_vs30_map.py

A UCVM utility script called plot_vs30_map does a few things. It discritizes a region, and then it queries the specific grid points, queries data values from 0-29m, adds them using a slowness calculation, and plots a map with the vs30 values shown.

The script has a query interface, but selected capabilities, such as an output file name, and an output image name are not available through that interface. Standard interface is a command line.

Running plot_vs30_map

In addition to the png plot, a metadata file of the run and an output data file is generated. This output data can be reused as input data to plot_vs30_map with different display parameters to create a new png plot base on the same set of input data.

 -bash-4.2$ ./plot_vs30_map.py -b 30.5,-126.0 -u 42.5,-112.5 -s 0.2 -a s -c cs173 -o vs30_cs173_map.png

Run using Input File

Run plot_vs30_map.py with input data set generated in the earlier example, and re-create map with discrete color scale.

-bash-4.2$ ./plot_vs30_map.py -b 30.5,-126.0 -u 42.5,-112.5 -s 0.2 -a d -c cs173 -o vs30_cs173h_d_map.png -f vs30_cs173h_data.bin
