UCVM with SFCVM

Software stack for supporting geomodelgrid based format:

  1. curl (curl-7.87.0)
  2. hdf5 (hdf5-1.10.9)
  3. openssl (openssl-3.0.8)
  4. proj (proj-8.1.1)
  5. sqlite (sqlite-autoconf-3400100)
  6. tiff (tiff-4.5.0)

SFCVM in UCVM

geomodelgrid based SFCVM is set with

   
    geomodelgrids_squery_setSquashing(sfcvm_geo_query_object, GEOMODELGRIDS_SQUASH_TOPOGRAPHY_BATHYMETRY);
    geomodelgrids_squery_setSquashMinElev(sfcvm_geo_query_object, SFCVM_SquashMinElev);

where SFCVM_SquashMinElev is default to -5000m (sfcvm is elevation based, depth is negative value)

NOTE: For locations that are below water, their geomodelgrids_squery_queryTopoBathyElevation() could return a NA value and so a grid height is added across the board to always have an usable value.

New command line option for model specific configuration

UCVM option:

-P Optional model configuration(model_param:key,value)


Example:

ucvm_query -l 37.455000,-121.941,3000 -m sfcvm -f ../../conf/ucvm.conf -P sfcvm_param:SquashMinElev,-5000.0


Allows multiple -P options,

ucvm_query ... -P cvmh_param:USE_1D_BKG,False -P cvmh_param:USE_GTL,False

Status result,

step count is the number of query that needed stepping down

max loops is the max number of looping a step-down query needed ie. there is a location that needs to go down to 125+(22*25) meters before finding a valid data

DONE:
    total query count=(6461)
    total gabbro count=(0)
    total water count=(894)
    total water step count=(890)
    total water loop count=(435)
    max water loops =(22)
