Image
Analysis Toolbox (IAT) was completed with the
addition of more analysis tools, imagery and imagery types. Near-complete
coverage of the province with Landsat 7 (ETM+) imagery and 40 ASTER images
are now available. Two new tools, the Tasseled Cap Transformation and the
Spectral Angle Mapper (SAM) were added. Program enhancements were also made
to the existing IAT programs to increase their efficiency and capability.
See Fieldwork 2004
for details. This BC and Yukon Chamber of Mines’
Rocks to Riches program was delivered by Cal Data Ltd. and began with
Phase 1, published January 5,
2003. The IAT is a framework to add, process and display a variety
of multi- and hyper-spectral imagery. The IAT includes Enhanced Satellite
Imagery delivered by McElhanney Consulting Services Ltd. A description of
these projects and use of the IAT are available in Fieldwork 2003,
p. 209-215 and in Fieldwork 2004,
p. 231-235.

July 16, 2004: Added Geochemistry Symbol Resizing.
This feature is useful for reducing the size of the geochemistry symbols
for plots. It is available for the layers in the Regional
Geochemistry Tool and the layers, except label layers, in the Regional Geochem Layers group in the legend. To resize: 1) zoom to appropriate
scale; 2) turn on layer to resize; 3) click 'Symbol Layer to Resize'
button, the Layer Name appears in the box and is removed from the
legend (do not modify the Layer Name label); 4) adjust the Symbol Size Factor (e.g. 0.5 to reduce by half);
5) click 'Process' and the new layer is created with the resized symbol.
