Aerial Photos 2004 Color-Infrared
Use
the map below to view or download each photo (click on the section
numbers). The photos were taken on June 16, 2004. The on-the-ground pixel
resolution of the images is approximately 2 feet, and the images are
rectified to within about 2 feet of existing survey control in the City and
about 5 feet of existing survey control in the Lake Whatcom Watershed. The
West half of the imagery (covering the salwater shoreline) was flown at a
minus 1.7 to minus 1.9 low tide. The near-infrared part of the
electromagnetic spectrum reflects very strongly from objects with
photo-synthetic pigment (vegetation). This makes color-infrared imagery very
useful for classifying plant communities, delineating wetlands, and
estimating impervious surfaces. If you choose to
download the image files via
FTP and plan to use them in the GIS environment make sure to download the
"world" file for each image (the files with "jgw" extensions).
Normal color copies of the images
are also available.
File Size Warning: Each of these images are approximately 1,300K in
size. It may take a long time to download each image. For more information please contact the
Planning Division.
