South Central Ontario Orthophotography Project (SCOOP) 2013 Digital Terrain Model (DTM) Coordinate system: 3857 - "WGS84 Web Mercator (Auxiliary Sphere)" Abstract: The SCOOP 2013 DTM is a 2m raster elevation product that was generated from the SCOOP 2013 Classified LAS. DTM is used for referencing elevations for mapping or engineering work and can be used to generate contours for the same.

  Supplemental Information:

  The derived raster products (DSM and DTM) are a result of a completely automated process. These products are not intended to be a definitive final product to support all types of business needs. It is intended to assist users in further refinement of the elevation. Here is a list of known issues:

  1) The water contains a lot of noise and is not flat or flowing downstream.

  2) The pixel correlated elevation (raw LAS) was unable to penetrate dense canopy and therefore there is a lack of points to truly represent the surface in canopy.

  3) There are many erroneous points that have not been classified properly. These points will be represented in the DSM or DTM as either a pit or a spike.
