Feature to Raster
Converts features to a
raster dataset.
1. Input features
The input feature
dataset to be converted to a raster dataset.
2. Field
The field used to assign
values to the output raster.
It can be any field of
the input feature dataset's attribute table.
If the Shape field of a
point or multipoint dataset contains z or m values, then either of these can be
used.
3. Output raster
The output raster
dataset to be created.
When not saving to a
geodatabase, specify .tif for a TIFF file format, .CRF for CRF file format,
.img for an ERDAS IMAGINE file format, or no extension for an Esri Grid raster
format.
4. Output cell size (optional)
The cell size for the
output raster being created.
This parameter can be
defined by a numeric value or obtained from an existing raster dataset. If the cell
size hasn’t been explicitly specified as the parameter value, then the
environment cell size value is used if specified; otherwise some additional
rules are used to calculate it from the other inputs. See the usage for more
detail.

Float to Raster
Converts a file of
binary floating-point values representing raster data to a raster dataset.
1. Input floating point raster file
The input floating-point
binary file.
The file must have a
.flt extension. There must be a header file in association with the
floating-point binary file, with a
.hdr extension.
2. Output raster
The output raster
dataset to be created.
When not saving to a
geodatabase, specify .tif for a TIFF file format, .CRF for CRF file format,
.img for an ERDAS IMAGINE file format, or no extension for an Esri Grid raster
format.

LAS Dataset to Raster
Creates a raster using
elevation, intensity, or RGB values stored in the lidar points referenced by
the LAS dataset.
1. Input LAS Dataset
The LAS dataset to
process.
2. Output Raster
The location and name of
the output raster. When storing a raster dataset in a geodatabase or in a
folder such as an Esri Grid, no file extension should be added to the name of
the raster dataset. A file extension can be provided to define the raster's
format when storing it in a folder, such as .tif to generate a GeoTIFF or .img
to generate an ERDAS IMAGINE format file.
If the raster is stored
as a TIFF file or in a geodatabase, its raster compression type and quality can
be specified using geoprocessing environment settings.
3. Value Field (optional)
The lidar data that will
be used to generate the raster output.
- ELEVATION—Elevation from the lidar files will be used to create the raster. This is the default.
- NTENSITY—Intensity information from the lidar files will be used to create the raster.
- RGB—RGB values from the lidar points will be used to create 3-band imagery.
4. Interpolation Type (optional)
The interpolation
technique that will be used to determine the cell values of the output raster.
The binning approach
provides a Cell Assignment Method for determining each output cell using the
points that fall within its extent, along with a Void Fill Method to determine
the value of cells that do not contain any LAS points.
Cell Assignment Methods
- AVERAGE—Assigns the average value of all points in the cell. This is the default.
- MINIMUM—Assigns the minimum value found in the points within the cell.
- MAXIMUM—Assigns the maximum value found in the points within the cell.
- IDW—Uses Inverse Distance Weighted interpolation to determine the cell value.
- NEAREST—Uses Nearest Neighbor assignment to determine the cell value.
Void Fill Methods
- NONE—NoData is assigned to the cell.
- SIMPLE—Averages the values from data cells immediately surrounding a NoData cell to eliminate small voids.
- LINEAR—Triangulates across void areas and uses linear interpolation on the triangulated value to determine the cell value. This is the default.
- NATURAL_NEIGHBOR—Uses natural neighbor interpolation to determine the cell value.
The Triangulation
interpolation methods derive cell values using a TIN based approach while also
offering the opportunity to speed up processing time by thinning the sampling
of LAS data using the Window Size technique.
Triangulation Methods
- Linear—Uses linear interpolation to determine cell values.
- Natural Neighbors—Uses natural neighbor interpolation to determine cell value.
Window Size Selection
Methods
- Maximum—The point with the highest value in each window size is maintained. This is the default.
- Minimum—The point with the lowest value in each window size is maintained.
- Closest To Mean—The point whose value is closest to the average of all point values in the window size is maintained.
5. Output Data Type (optional)
Specifies the type of
numeric values stored in the output raster.
- FLOAT—Output raster will use 32-bit floating point, which supports values ranging from -3.402823466e+38 to 3.402823466e+38. This is the default.
- NT—Output raster will use an appropriate integer bit depth. This option will round z-values to the nearest whole number and write an integer to each raster cell value.
6. Sampling Type (optional)
Specifies the method
used for interpreting the Sampling Value to define the resolution of the output
raster.
- OBSERVATIONS—Defines the number of cells that divide the lengthiest side of the LAS dataset extent.
- CELLSIZE—Defines the cell size of the output raster. This is the default.
7. Sampling Value (optional)
Specifies the value used in conjunction with the Sampling Type to
define the resolution of the output raster.
8. Z Factor (optional)
The factor by which z-values will be multiplied. This is typically used to convert Z linear units to match XY linear units. The default is 1, which leaves elevation values unchanged. This parameter is disabled if the spatial reference of the input surface has a Z datum with a specified linear unit.
