LIDAR Eastern Acquisition Project (LEAP), Digital Terrain Model (DTM) (2009)


LIDAR Eastern Acquisition Project (LEAP), Digital Terrain Model (DTM) 2009 consists of a 1 metre resolution Digital Terrain Model based upon elevation information derived from returns collected by an airborne lidar sensor. The data was acquired and delivered during May and December 2009.

This data covers an area including Prince Edward County, with a total project area of 4567 KM2 encompassing the Picton ecodistrict.

Spatial reference and data type

These data are available in geographic co-ordinates; horizontal datum is North American Datum (NAD) 83, UTM zone 18N. These rasters are stored as 1km square tiles. Other data formats can be accommodated as the Geospatial Centre has access to a number of conversion utilities.

Data access

In order to access these data sets, please visit the Geospatial Centre reference desk during regular reference hours. Library reference staff are available to provide further information about these data sets and to deliver data upon request. Under the terms of the library's license agreement, these data sets are for the exclusive use of the students, faculty and staff at the University of Waterloo, and may be used for educational/academic purposes only.

Data manipulation

There are public workstations in the Geospatial Centre that provide access to ArcGIS software programs, program extensions and data manipulation utilities. Patrons may use the Geographic Information System (GIS) software in the library to view and manipulate the data. UWaterloo faculty, students and staff may copy these data to other media (for example: CD, DVD or Zip disc) for use elsewhere.

Data output

These data may be exported from ArcGIS in a choice of bitmapped formats (also known as raster graphics) including JPG, TIFF, GIF, and BMP or in a choice of vector graphics formats including Adobe Illustrator (AI), Encapsulated Postscript (EPS), and Scalable Vector Graphics (SVG). Yet another option is PDF. Patrons may use the library's printer to print map views or tabular views of the data.
