【问题描述】
A digital elevation model (DEM) is a raster representation of a continuous surface in which each cell represents the elevation at a location. Raster data, such as DEMs, can be converted to vector datasets to increase analytical capabilities. The line features obtained from the raster data can be used to measure the length, for example, of a road centerline or hydrology.
The instructions provided describe how to convert the flow accumulation lines from a DEM file to a polyline shapefile in ArcMap.
