Query#

Full name: geomodelgrids.Query

Enums#

SquashingEnum#

SQUASH_NONE No squashing.
SQUASH_TOP_SURFACE Squash model so top surface is flat.
SQUASH_TOPGRAPHY_BATHYMETRY Squash model so topography/bathymetry surface is flat.

Constants#

NODATA_VALUE Value returned when query could not return a valid value.

Methods#

Query()#

Constructor.

initialize(models: list(Model), values: list(str), input_crs: str)#

Perform initialization required to query the models.

models List of model filenames (in query order).
values List of names of values to return in queries.
input_crs CRS as string (PROJ, EPSG, WKT) for input points.

set_squash_min_elev(min_elev: float)#

Turn on squashing using the top surface and set the minimum elevation for squashing.

min_elev Elevation in meters.

set_squashing(squash_type: SquashingEnum)#

Set type of squashing.

squash_type Squashing setting (SQUASH_NONE, SQUASH_TOP_SURFACE, SQUASH_TOPOGRAPHY_BATHYMETRY)

query_top_elevation(points: numpy.ndarray)#

Query model for elevation of the top surface at a point using bilinear interpolation.

points NumPy array [numPoints, 2[ of point coordinates in input CRS.
returns NumPy array of elevation (meters) of surface at each point.

query_topobathy_elevation(points: numpy.ndarray)#

Query model for elevation of the topography/bathymetry surface at a point using bilinear interpolation.

points NumPy array [numPoints, 2] of point coordinates in input CRS.
returns NumPy array of elevation (meters) of surface at each point.

query(points: numpy.ndarray)#

Query model for values at a point using bilinear interpolation

points NumPy array [numPoints, 3] of point coordinates in input CRS.
returns Tuple(values, status) where values is a NumPy array of model values at each point and status is a NumPy array with ErrorHandler.OK for a point if returning a valid value and ErrorHandler.WARNING for a point if unable to return a valid value.
