How to avoid error in Topo to raster?
Increase the output cell size in the Topo to Raster window to avoid error. If the large size of an input feature class seems to be causing issues, split the data to create smaller processing extents and then run the Topo to Raster tool separately on each of the extents.
How to use stream data in Topo to raster?
Stream data is a powerful way of adding topographic information to the interpolation, further ensuring the quality of the output DEM. For point data at 1:100,000 scale, use 5.0 and 200.0. For less dense point data up to 1:500,000 scale, use 10.0 and 400.0. For contour data with contour spacing of 10, use 5.0 and 100.0.
How are arcs oriented in Topo to raster?
All arcs must be oriented to point downstream. The feature class should only contain single arc streams. TopoSink ( [ [inFeatures, {field}],…]) A point feature class that represents known topographic depressions. Topo to Raster will not attempt to remove from the analysis any points explicitly identified as sinks.
What does boundary mean in Topo to raster?
A boundary is a feature class containing a single polygon that represents the outer boundary of the output raster. Cells in the output raster outside this boundary will be NoData. This option can be used for clipping out water areas along coastlines before making the final output raster.
Can a feature be converted to a raster?
Any feature class (geodatabase, shapefile, or coverage) containing point, line, or polygon features can be converted to a raster dataset. The input field type determines the type of output raster. If the field is integer, the output raster will be integer; if it is floating point, the output will be floating point.
Which is the field used to assign values to raster?
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. The output raster dataset to be created.
What happens when cell size is specified in raster?
If the cell size has been specified using a numeric value, the tool will use it directly for the output raster. If the cell size has been specified using a raster dataset, the parameter will show the path of the raster dataset instead of the cell size value.
