GM_GridGenSetup_t Fields |
The GM_GridGenSetup_t type exposes the following members.
Name | Description | |
---|---|---|
mBounds | (GM_Rectangle_t*)Bounding box to grid to in current proj units. Pass NULL to use the combined bounds of all input layers (the default). | |
mDesc | Grid description | |
mElevUnits | Units to generate grid at (elevation values in other units will be converted as needed) | |
mFlags | Flags for grid generation | |
mGridAlg | Algorithm to use for creating elevation grid (if any) | |
mGridBinMult | Grid bin multiplier for use if using a bin-based grid method. This is multiple of calculated point density. | |
mLidarBreaklineBinMult |
Number of cells to clear from a Lidar grid around 3D breaklines before applying breakline heights
and filling gaps (valid if GM_GridGen_ApplyLidarBreaklines used). Typically in range 1-4.
| |
mTaperValue | Taper value for gridding areas. 0.0 for no taper (default) | |
mTightnessMult |
Grid tightness multiplier (multiplies resolution) for discarding values far from a sample.
Default of zero discards nothing. For Lidar bin gridding you typically do NOT want to use 0 as it
it can be very slow to fill all gaps in irregular Lidar data. Use GM_GRID_DISABLE_GAP_FILL to disable
gap filling altogether. For Lidar bin grids, gap fill values in the range 1-32 are common.
| |
mXRes | X resolution (in current proj units) to generate grid at (use 0.0 for auto-spacing determination) | |
mYRes | Y resolution (in current proj units) to generate grid at (use 0.0 for auto-spacing determination) |
