Collection search - Side Looking Aperture Radar (SLAR) Imagery [cartographic material (electronic)]

Material was transferred to the Visual and Sound Archives by the Canadian Ice Service on their original tapes. ERAR/VSA made archival copies from the source tapes.

Also contains a textual, electronic LOG file created during the data extraction. It includes: Folder Name, Extraction Date, Data Capture Date, Extraction Information (filename, filesize, start time, stop time), Data Capture Information (filename, number of lines), Summary (Total Bytes / Files copied and time interval), and Error Message, if applicable.

There are no restrictions on access.

Tactical SLAR imagery is raw radar imagery. It can be viewed using the following software: Adobe Photoshop 9 (and possibly earlier and later software versions) via the Open option or ERDAS Imagine 8.7 (and possibly earlier and later software versions).

If Adobe Photoshop is used to access the imagery, the following information is required: header size (1024), width (4160) and length (varies and can be automatically calculated by Photoshop or obtained from the number of lines field in the electronic LOG file).

If ERDAS Imagine is used to access the imagery, an additional computer file (.gen) will be required; refer to Mikan 213664 for further information. The imagery will appear in mirrored format and should be reoriented.
