Southwestern Ontario Orthophotography Project (SWOOP) (2010)

Description

Land Information Ontario, as well as most municipalities in Southwestern Ontario and a number of other public and private sector organizations collaborated to acquire digital orthophotography for approximately 45,572 square kilometres of land in Southwestern Ontario. The geographic area of SWOOP 2010 includes buffers along the borders between Ontario and the State of Michigan and the State of New York as shown in the figure below.

Swoop 2010 extent

Resolution for airphotos is 20 cm with horizontal and vertical accuracy of 50 cm. The air photos were taken in April/Map 2010 to ensure leaf-off, no-snow conditions.

Coverage of the Region of Waterloo consists of over 1500 image tiles. You may wish to consult the following indexes for tile numbers.

Spatial reference and data type

These georeference 1km square images are available in Universal Transverse Mercator (UTM) coordinates; horizontal datum is North American Datum (NAD) 83 UTM zone 17. They are stored as compressed JPEG 2000 format. Average files size is 5 MB.

Data access

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.

Data manipulation and storage

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. Waterloo faculty, students and staff may copy these data 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 GeoExpressView may also be used to export the image, in whole or in part. The user defines the output resolution.
