Digital Raster Acquisition Project for the East (DRAPE) imagery (2008 - 2009)

Description

Digital Rastor Acquisition Project for the East imagery (DRAPE) was received from the Ontario Ministry of Natural Resources. The imagery covers approximately 54,000 square kilometres in eastern Ontario and was taken between January 2008 - January 2009. Imagery is available in either 1 km tiles or mosaiced 20 km tiles.

Data collection came from multiple remote sensing data products at 30 cm and 10 cm resolution. The Province of Ontario managed the imagery and made available a resampled 50 cm version of this data.

Over 50 organizations contributed funding to the project including: Ontario Government ministries, municipalities, conservation authorities, private sector organizations, non-government organizations and a few federal departments.

DRAPE imagery covers the following counties/ districts:

Frontenac County
Haliburton County

Keptville District
Leeds and Grenville United Counties
Lenark County
Lennox and Addington County
Nippissing District
Northumberland County
Ottawa-Carlton Regional Municipality
Peterborough County
Prince Edward County
Renfrew County

Spatial reference and data type

These georeferenced images are available in Universal Transverse Mercator (UTM) coordinates; horizontal datum is North American Datum (NAD) 83. They are stored as 50 cm true colour 1km x 1km MrSID tiles and MrSID compressed mosaic othos. Average file size for 1km tiles is 4MB and 1GB for 20Km tiles.

Data access

In order to access these data sets, please visit the Map Library 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.

Data manipulation and storage

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.

Data output

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.
