AbstractThis report highlights the Iqaluit watershed assessment activity conducted by scientists from Natural Resources Canada. This activity included the use of high resolution satellite imagery and on-site field surveys to map Lake Geraldine's watershed boundary and lake depth. Lake Geraldine is the water supply source of the city of Iqaluit. This activity was also used as a technology transfer exercise, whereby local members of the community and the Nunavut Government were trained to understand and use a set of tools and solutions for conducting small lake surveys and for collecting GPS locations. This document is copyright of Natural Resources Canada and contains copyrighted material of Digital Globe Inc, the provider of the Quickbird high resolution satellite image shown in this report.
Digital computer files resulting from this project and described in this document, are available freely and are grouped under the same publication file. The digital files comprise of:
- Vector file of the watershed outline (ESRI shapefile.shp).
- Raster file illustrating the water depth model of Lake Geraldine (Geotiff.tif)
- Vector file illustrating the depth contours (isobaths) of Lake Geraldine (ESRI shapefile.shp).
- Tabular statistics featuring the water volume for Lake Geraldine.
- Lake volume statistics stored as .kml file (Keyhole Markup Language) viewable on tools such as Google Earth.
- Vector file illustrating the depth contours of Lake Geraldine stored as an .img file compatible with Garmintm GPS map devices.
- Under water video camera footage (.avi/.asf)
