Member Data Documentation

dfAngle

double GDALGridDataMetricsOptions::dfAngle

Angle of ellipse rotation in degrees.

Ellipse rotated counter clockwise.

dfNoDataValue

double GDALGridDataMetricsOptions::dfNoDataValue

No data marker to fill empty points.

dfRadius1

double GDALGridDataMetricsOptions::dfRadius1

The first radius (X axis if rotation angle is 0) of search ellipse.

dfRadius2

double GDALGridDataMetricsOptions::dfRadius2

The second radius (Y axis if rotation angle is 0) of search ellipse.

nMaxPointsPerQuadrant

GUInt32 GDALGridDataMetricsOptions::nMaxPointsPerQuadrant

Maximum number of data points to use for each of the 4 quadrants.

Do not search for more points than this number.

nMinPoints

GUInt32 GDALGridDataMetricsOptions::nMinPoints

Minimum number of data points to average.

If less amount of points found the grid node considered empty and will be filled with NODATA marker.

nMinPointsPerQuadrant

GUInt32 GDALGridDataMetricsOptions::nMinPointsPerQuadrant

Minimum number of data points to use for each of the 4 quadrants.

If less amount of points found the grid node considered empty and will be filled with NODATA marker.

nSizeOfStructure

size_t GDALGridDataMetricsOptions::nSizeOfStructure

Added in GDAL 3.6 to detect potential ABI issues. Should be set to sizeof(GDALGridDataMetricsOptions)
