Toolbox
Raster Domain
Constructs a 3D polygon
or polyline delineating the height along the boundary of a raster surface.
1. Input Raster
The raster to process.
2. Output Feature Class
The feature class that
will be produced by this tool.
3. Output Feature Class Type
The geometry of the
output feature class.
·
LINE—The output will be a z-enabled line feature class.
· POLYGON—The output will be a z-enabled polygon feature class.

Raster to Multipoint
Converts raster cell centers
into 3D multipoint features whose Z values reflect the raster cell value.
1. Input Raster
The raster to process.
2. Output Feature Class
The feature class that
will be produced by this tool.
3. Output VIP table (optional)
The histogram table to
be produced when VIP Histogram is specified for the Method parameter.
4. Method (optional)
The thinning method
applied to the input raster to select a subset of cells that will be exported
to the multipoint feature class.
·
NO_THIN—No thinning will be applied. This is the default.
·
ZTOLERANCE <value>—Only exports the cells that are required
for maintaining a surface within the specified Z-range of the input raster. The
corresponding value reflects the maximum allowable difference in z units
between the input raster and the surface created from the output multipoint
feature class. When selecting this method, the thinning value defaults to one
tenth of the z range of the input raster.
·
KERNEL <value>—Divides the raster into equal sized tiles
based on the thinning value, then selects one or two cells which meet the
criteria defined by the designated kernel method. The corresponding value
defaults to 3, which means the raster would be divided into 3 cell by 3 cell
windows.
·
VIP <value>—Employs a roving 3 cell by 3 cell window that is
used to create a 3-dimensional best fit plane. Each cell is given a
significance score based on its absolute deviation from this plane. A histogram
of these scores is then used to determine the cells that get exported. The
corresponding value reflects the percentile rank along the histogram of
significance scores. This value defaults to 5.0, which means the cells whose
score was within the top 5% of the histogram will be exported.
·
VIP_HISTOGRAM—Creates a table to view the actual significance
values and the corresponding number of points associated with those values.
5. Kernel Method (optional)
The selection method
used within each kernel neighborhood when kernel thinning is applied on the
input raster.
·
MIN—A point is created at the cell with the smallest elevation
value found in the kernel neighborhood. This is the default.
·
MAX—A point is created at the cell with the largest elevation
value found in the kernel neighborhood.
·
MINMAX—Two points are created at the cells with the smallest and
largest Z values found in the kernel neighborhood.
·
MEAN—A point is created at the cell whose elevation value is
closest to the average of the cells in the kernel neighborhood.
6. 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.
Raster to TIN
How
to use Raster to TIN Tool in Arc Toolbox ArcMap
ArcGIS ??Raster to TIN
Raster to TIN Tool, From Raster Toolset, Conversion Toolset, 3D Analyst
Toolbox
Raster to TIN
Converts a raster to a
triangulated irregular network (TIN) dataset.
1. Input Raster
The raster to process.
2. Output TIN
The TIN dataset that
will be generated.
3. Z Tolerance (optional)
The maximum allowable
difference in (z units) between the height of the input raster and the height
of the output TIN. By default, the z tolerance is 1/10 of the z range of the
input raster.
4. Maximum Number of Points (optional)
The maximum number of
points that will be added to the TIN before the process is terminated. By
default, the process will continue until all the points are added.
5. Z Factor (optional)
The factor that the height values of the raster will be multiplied by in the resulting TIN dataset. This is typically used to convert Z units to match XY units.
