These digital orthoimages provide complete coverage of Lambton County (west of Middlesex County). These full colour images were flown in April 2002 by J D Barnes and provided to the Geospatial Centre by the Ministry of Natural Resources in October 2004. The pixel resolution of these images is 30 cm. The Geospatial Centre also has related 2002 coverage of the Greater Toronto Area and adjacent areas including Grey, Simcoe, and Kawartha Lakes.
You can use this image index to determine the 11-digit tile identifiers (e.g., 17 6320 48580) for the images that interest you.
These georeferenced images are available in Universal Transverse Mercator (UTM) coordinates; horizontal datum is North American Datum (NAD) 83. They are stored as compressed MrSID data files, with accompanying Sid World (SDW) files. Average file size for one of these MrSID images is 1.7 MB.
In order to access these data sets, please visit the Geospatial Centre reference desk during 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 use by students, faculty, and staff at the University of Waterloo only.
There are public workstations in the Geospatial Centre that provide access to both ArcGIS and ArcView software programs, program extensions and data manipulation utilities. Patrons may use the Geographic Information System (GIS) and image processing 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.
These images 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. The user defines the output resolution.
These data are provided for personal use for academic, research, and/or teaching purposes. A data release agreement must be agreed to before these licensed data can be released. The Ministry of Natural Resources must be acknowledged on any derivative product, whether printed or electronic, including for example, a printed map, a raster or vector graphic, a web-based application, etc. Patrons are advised to fully respect the provisions of Canada's Copyright Act as well as terms and conditions imposed by the data provider.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg, and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
