What is pour point data?
The Snap Pour Point tool is used to ensure the selection of points of high accumulated flow when delineating drainage basins using the Watershed tool. If the input pour point data is a point feature class, it will be converted to a raster internally for processing.
What is pour point test?
Pour point is defined as the lowest temperature at which the test fluid can be poured under the prescribed test conditions. It is one of the properties that determine the low temperature fluidity of a lubricating oil.
What is the pour point of diesel?
Pour point is an important quality specification for diesel fuels. Specifically, it is a measure of the tendency of a fuel to become more viscous and resist flowing when cold.
Where does the pour point come from in watershed?
When the pour point is a point feature dataset, the values will come from the specified field. The Watershed tool only supports a D8-type of input flow direction raster. This can be created using the Flow Direction tool, run with default flow direction type D8 (in Python, with the D8 option).
Where does the watershed value come from in ArcGIS?
The value of each watershed will be taken from the value of the source in the input raster or feature pour point data. When the pour point is a raster dataset, the cell values will be used. When the pour point is a point feature dataset, the values will come from the specified field.
When to use cell values in watershed tool?
When the pour point is a raster dataset, the cell values will be used. When the pour point is a point feature dataset, the values will come from the specified field. The Watershed tool only supports a D8-type of input flow direction raster.
When to use a numeric field in watershed?
If the pour point dataset is a raster, use Value. If the pour point dataset is a feature, use a numeric field. If the field contains floating-point values, they will be truncated into integers. The output raster that shows the contributing area. This output is of integer type. The input raster that shows the direction of flow out of each cell.
