    dct:description """<p><b><font size='4'>This dataset has been deprecated. Please use our <a href='https://data-lakecountyil.opendata.arcgis.com/search?tags=2017%20digital%20elevation%20model' rel='nofollow ugc' target='_blank'>2017 Digital Elevation Models</a> instead.</font></b></p><p style='margin-top:0in; margin-right:0in; margin-bottom:7.5pt; margin-left:0in; background:white;'><span style='font-family:&quot;Helvetica&quot;,sans-serif; color:#4C4C4C;'>The
Digital Terrain Model (DTM) is a 3.28 foot pixel resolution raster in GeoTIFF
format upsampled to 2.5 feet to preserve detail. This was created using the
ground (class = 2) lidar points and incorporating the breaklines.</span></p>

DTMs were developed using LiDAR data. LiDAR is an acronym for LIght Detection
And Ranging. Light detection and ranging is the science of using a laser to
measure distances to specific points. A specially equipped airplane with
positioning tools and LiDAR technology was used to measure the distance to the
surface of the earth to determine ground elevation. The classified points were
developed using data collected in April to May 2007. The LiDAR points,
specialized software, and technology provide the ability to create a high
precision three-dimensional digital elevation and/or terrain models (DEM/DTM).
The use of LiDAR significantly reduces the cost for developing this
information.</span></p>

DTMs are intended to correspond to the orthometric heights of the bare surface
of the county (no buildings or vegetation cover). DTM data is used by county
agencies to study drainage issues such as flooding and erosion; contour
generation; slope and aspect; and hill shade images. This dataset was compiled
to meet the American Society for Photogrammetry and Remote Sensing (ASPRS)
Accuracy Standards for Large-Scale Maps, CLASS 1 map accuracy.</span></p>
