Title: AHED Canals and Streams (Hydro Edges)

Geospatial Data Presentation Form: vector digital data

Description:

Abstract: Canals and streams (AHED HydroEdges) are the network of lines describing the map hydrography. The HydroEdge feature class was populated using the 1:24000 National Hydrography Dataset (NHD). There are two subtypes of HydroEdges: Flowline, which traces water movement, and Shoreline, which forms the interface between land and water where it is not defined by a waterbody polygon. HydroEdge geometry imagery for primary and secondary features has been edited for correctness using the District's aerial. According to the Arc Hydro Model, the end points of HydroEdges are always covered by point features called HydroJunctions.

Purpose: AHED (Arc Hydro Enhanced Database) provides a geographically comprehensive database of hydrographic and hydrologic features for the South Florida Water Management District (SFWMD).
