Query#

Full name: geomodelgrids::serial::Query

Enumerated types#

SquashingEnum#

SQUASH_NONE No squashing.
SQUASH_TOP_SURFACE Squash relative to the top surface of the model.
SQUASH_TOPOGRPAHY_BATHYMETRY Squash relative to the topography/bathymetry surface.

Methods#

Query()#

Constructor.

getErrorHandler()#

Get the error handler.

initialize(const std::vector<std::string>& modelFilenames, const std::vector<std::string>& valueNames, const std::string& inputCRSString)#

Setup for querying.

modelFilenames[in] Array of model filenames (in query order).
valueNames[in] Array of names of values to return in query.
inputCRSString[in] Coordinate reference system (CRS) as string (PROJ, EPSG, WKT) for input points.

setSquashMinElev(const double value)#

Set minimum elevation (m) above which vertical coordinate is given as -depth.

This option is used to adjust (squash) topography to sea level above value. Below value the original geometry of the model is maintained. For example, this maintains the original geometry of deeper structure.

value[in] Minimum elevation (m) for squashing topography.

setSquashing(const SquashingEnum value)#

Set type of squashing.

value[in] True if squashing is on, false otherwise.

double queryTopElevation(const double x, const double y)#

Query model for elevation of the top surface of the model at a point using bilinear interpolation (interpolation along each model axis).

x[in] X coordinate of of point in (in input CRS).
y[in] Y coordinate of of point in (in input CRS).
return value Elevation (meters) of top surface at point.

double queryTopoBathyElevation(const double x, const double y)#

Query model for elevation of the topography/bathymetry surface of the model at a point using bilinear interpolation (interpolation along each model axis). If the model does not contain a topography/bathymetry surface, then the top surface of the model is used.

x[in] X coordinate of of point in (in input CRS).
y[in] Y coordinate of of point in (in input CRS).
return value Elevation (meters) of topography/bathymetry surface at point.

query(const double* values, const double x, const double y, const double z)#

Query model for values at a point using trilinear interpolation (interpolation along each model axis).

values[out] Array of values (must be preallocated).
x[in] X coordinate of of point in (in input CRS).
y[in] Y coordinate of of point in (in input CRS).
z[in] Z coordinate of of point in (in input CRS).

finalize()#

Cleanup after querying.
