Command Reference

ucvm_query

This is the basic UCVM interface that queries velocity model of interest.

*A command line query

ucvm_query -f /usr/local/opt/ucvm/conf/ucvm.conf -m cvmh -l 33.84007,-117.95683,0.0
Using Geo Depth coordinates as default mode.
 -117.9568    33.8401      0.000     34.438    293.500       cvmh   1238.170    120.690   1450.659       none      0.000      0.000      0.000      crust   1238.170    120.690   1450.65

• Review input file as:

-bash-4.2$ cat ./tests/inputs/test_latlons.txt
-118.0 34.0 0.0
-118.0 34.0 50.0
-118.0 34.0 100.0
-118.0 34.0 500.0
-118.0 34.0 1000.0

• Invoke basic ucvm_query, specifying CVM-S4.26.M01 (as cvmsi):

-bash-4.2$ ./bin/ucvm_query -f ./conf/ucvm.conf -m cvmsi < ./tests/inputs/test_latlons.txt > ./ucvm_query_results.txt

cat ucvm_query_results.txt

The results are in a column oriented format. Abbreviations are like this:

tput format is:
   0   1  2  3    4     5       6     7     8     9   10      11    12       13     14      15     16
  lon lat Z surf vs30 crustal cr_vp cr_vs cr_rho gtl gtl_vp gtl_vs gtl_rho cmb_algo cmb_vp cmb_vs cmb_rho

The first three colums are input values, the remaining columns are information about the velocity model used provide the material properties. Crustal models, and Geotechnical Models can be stored and used seperately in UCVM. The contributions of each model are shown in columns 5-8 and 10-12, but the combined results returned in 14-16 are typically used by modelers.

plot_cross_section.py

This is the basic UCVM plotting script that plots a cross section bounded by two latlng points, based on matplotlib.

-bash-4.2$ ./plot_cross_section.py -b 34.0,-118.75 -u 34.0,-117.75 -h 100 -v 10 -d vs -c cvms -a s -s 0 -e 4000 -o cross.png
Using parameters:

lat1 = 34.0
data_type = vs
lat2 = 34.0
cvm_selected = cvms
ending_depth = 4000
horizontal_spacing = 100
color = s
lon1 = -118.75
vertical_spacing = 10
lon2 = -117.75
starting_depth = 0
