ArcGis converting raster data models to contour polyline features by XTools Pro
The purpose of the “Convert Grid to Contours” tool is converting raster data models (grids) to contour polyline features (relief isolines, for example) with specified parameters.
Contour is a line that typically connects points of equal elevation value on a terrain surface (an isoline). Grid is an opposite raster representation of geographic information. These two representations of geographic data are inter-convertible. Converting raster representation (Grid) is performed by defining contour parameters.
One Grid may have one or several bands. Band is a measure of a characteristic or quality of the features observed in a raster. Some rasters have a single band, others may have more than one. At that, only one band of a Grid can be converted to contours format in a single operation.
