Stereo DTM (Topographic Surface) ☀ Reference image of the traditional stereo-compiled DTM ☀ Built from Masspoints and Breaklines ☀ Much coarser resolution than lidar ☀ Demonstrates the familiar and usually expected character of a topographic DEM ☀ Most notably, the “flat” water surfaces Stream Waterbody

Pure LiDAR (Topographic Surface) ☀ DEM created only using Bare-Earth lidar points ☀ Surface contains extensive triangulation artifacts (“tinning”). ☀ Caused by the absence of: ☀ Flattening lidar returns from water ☀ Breakline constraints that would define buildings, water, and other features (as in the Stereo DTM). ☀ Aesthetically and cartographically unacceptable to most users Tinning in Water Areas

Hydro Flattened (Topographic Surface) ☀ The goal of the v13 Spec. ☀ Intent is to support the development of a consistent, acceptable character within the NED, suitable for contouring. ☀ Removes the most offensive pure lidar artifacts: those in the water. ☀ Constant elevation for waterbodies. ☀ Wide streams and rivers are flattened bank-to-bank and forced to flow downhill (monotonic). ☀ Carries ZERO implicit or explicit accuracy with regards to the represented water surface elevations – It is ONLY a Cartographic/Aesthetic enhancement. ☀ Building voids are too costly to correct. ☀ Most often achieved via the development and inclusion of hard breaklines. Stream Waterbody

Full Breaklines (Topographic Surface) ☀ A further possible refinement of the Hydro Flattened surface ☀ Removes artifacts from building voids ☀ Refines the delineation of roads, single-line drainages, ridges, bridge crossings, etc. ☀ Requires the development of a large number of additional detailed breaklines ☀ A higher quality topographic surface, but significantly more expensive. ☀ Not cost effective for the NED. Buildings Roads

Hydro Enforced (Hydrologic Surface) ☀ Surface used by engineers in Hydraulic and Hydrologic (H&H) modeling. ☀ NOT to be used for traditional mapping (contours, etc.) ☀ Similar to Hydro Flattened with the addition of Single Line Breaklines: Pipelines, Culverts, Underground Streams, etc… ☀ Terrain is then cut away at bridges and culverts to model drain connectivity ☀ Water Surface Elevations (WSEL) are often set to known values (surveyed or historical). Culverts Cut Through Roads

Hydro Conditioned (Hydrologic Surface) ☀ Another type of surface used by engineers for H&H modeling. ☀ Similar to the Hydro Enforced surface, but with sinks filled ☀ Flow is continuous across the entire surface – no areas of unconnected internal drainage ☀ Often Achieved via ArcHydro or ArcGIS Spatial Analyist Filled Sinks

Watershed Boundary Dataset ☀ WBD is combined with the National Hydrography Dataset, and shows watershed boundaries derived from the best available elevation data prescribed to identified drainage area ranges based on area.The number of digits in the code increases with smaller area. ☀ Watershed area becomes important as we strive to manage nutrient sources, storm-water, and invasive species and other conservation efforts. ☀ Particularly in areas of low relief or poor elevation data, refinements in watershed boundary will occur as new lidar is applied.
