SPOT Satellite Imagery of the Regional Municipality of Waterloo 1999

Description/Use:

Two image files, one multispectral, and one panchromatic, were acquired by the SPOT remote sensing satellite in 1999.

Spatial Reference and Data Type:

The first channel of the Multispectral image is band HRV3 (near IR, 0.79-0.89 µm) from the SPOT satellite; the second Multispectral channel is SPOT HRV2 (red, 0.61-0.68 µm); and the third Multispectral channel is SPOT HRV1 (green, 0.50-0.59 µm). The Multispectral image has been georeferenced to the UTM projection (UTM zone 17 NAD83) with a precision accuracy of better than 20 m. The spatial resolution of this image is 20 m. There have been no contrast enhancements applied to this image.

The Panchromatic image is a single-channel (i.e. black & white) scene acquired on September 19, 1999. This image was recorded in the visible light spectral region (0.51-0.73 µm). The Panchromatic image has been georeferenced to the UTM projection (UTM zone 17 NAD83) with a precision accuracy of better than 10 m. The spatial resolution of this image is 10 m. There have been no contrast enhancements applied to this image.

There are 4 files differentiated by unique file extensions - associated with each image:

JPG This is a small "thumbnail" view of the entire scene in JPG format. You may want to have a glance at this file first to see exactly what area the image covers.
TIF This is the image file in TIF format; it is approximately 50 Mb.
TFW This is the TIFF World File containing the geo-referencing information. You will need this file to import the image into a GIS.
TXT This is a text header file. This file is not required to use the image, but it contains some more details about the scene.
