Terrain Services
Welcome to IAGT LiDAR and Terrain Services. The following are examples of the types of data processing and terrain analysis services IAGT offers.
In addition to the services described in the attachments above, IAGT has experience integrating high resolution terrain data into raster based GIS modeling and in deriving additional value added data products from both LiDAR point clouds and resulting digital elevation and/or surface models.
Terrain Viewer
IAGT hosts a number of terrain visualizations through our TerraGate web server. These and similar visualizations are also available as distributable files and can be stored locally or on a network file server for open or secured access. The free viewer, TerraExplorer, must be installed to be able to access the visualization files. In order to launch any of the visualization files offered here, you must first download the free TerraExplorer viewer.
Once installed, clicking any one of the "Launch" buttons below will automatically load the selected visualization file. Please note that our current test server is limited to 10 active users at any one time. If you receive a server error message, please view our server statistics.
The following visualizations can be launched from this site:
- Monroe County, NY - Bare Earth LiDAR 10 ft2 DEM with orthophotography
- Monroe County, NY - Bare Earth USGS 10 m2 DEM with orthophotography
- Town of Penfield, NY - Bare Earth LiDAR 10 ft2 DEM with Orthophotography and GIS data.
- Ontario County, NY - Bare Earth LiDAR 10 ft2 DEM with Orthophotography and GIS data.

Click button to launch the IAGT
Terrain Viewer for the Town of Penfield. |

This visualization includes
the following GIS datasets:
- Floodplains
- Geology
- Parcels
- Slopes
- Soils
- Streams
- Waterbodies
- Wetlands
- Woodlots
Because of the volume of GIS Data integrated
with this visualization, the viewer may take several minutes
to load on your computer, and the performance may be slower
than for visualizations without additional GIS data.
Caution should be exercised if trying to turn on all the GIS data
layers at one time. It is recommended for maximum performance
to limit the number of GIS layers on display at any given
time to three (3). |
