ConvertToSurface_AllPorts

Description

The operator creates a raster surface by interpolation through a TIN over the specified or implied output extent. Areas outside the convex hull of the TIN will be NODATA. The area within the convex hull will not contain holes.

Limitations

None

Required

Default Behavior or Behavior if not Required

Input

IMAGINE.PointCloud

IMAGINE.Features

Input points. Features' primary geometry must be PointGeometry or VectorGeometry; non-point geometry types encountered in a VectorGeometry field will be ignored.

checkmark_gray

checkmark_gray

SurfaceAttribute

IMAGINE.String

The attribute used as the elevation value that is used to populate the raster surface pixel values

checkmark_gray

Uses the points' Z value if the port is empty. For Features a value is required if the primary geometry field is 2D (otherwise it is an error).

OriginX

IMAGINE.Double

The x coordinate in the input point cloud's CRS to be used to align the output raster's corner or cell center to it.

If empty this setting is ignored

OriginY

IMAGINE.Double

The y coordinate in the input point cloud's CRS to be used to align the output raster's corner or cell center to it.

If empty this setting is ignored

OriginAlignment

IMAGINE.String

The alignment option, either "Upper-left corner of cell" or "Center of cell". In order for this to work, all of OriginX, OriginY and OriginAlignment must be provided

"Center of cell".

CellSizeX

IMAGINE.Double

The cell size x for the output raster.

Determined on the fly based on point cloud point density.

CellSizeY

IMAGINE.Double

The cell size y for the output raster.

Determined on the fly based on point cloud point density.

CellSizeUnits

IMAGINE.String

The horizontal units of a cell.

Same as horizontal units of the input point cloud's CRS. If the input raster's CRS is unknown, the default is Meters

OutputExtent

IMAGINE.Boundary

The extent for the output raster, assumed to be in the input point cloud's CRS.

If not provided, the full point cloud extent will be used.

Surface

IMAGINE.Raster

The output surface
