2008 Simcoe/Muskoka/Dufferin orthoimagery

The Map Library has acquired large-tile 2008 ortho mosaics for Muskoka District, Simcoe County and east half of Dufferin County. The images are true colour 30cm resolution in MrSID compressed format. The mosaics are 20 km by 20 km and vary in size from 100 MB to over 600 MB.

Project area is approximately 14,000 sq km.

Data Update : Canadian Climate Dataset

After much interest from students in mapping temperature and precipitation in Canada, the Map Library has acquired the climate dataset from the National Land and Water Information Service.

The Daily 10km Gridded Climate Dataset for Canada 1961-2003 contains gridded point locations of daily maximum temperature (°C), minimum temperature (°C), and precipitation (mm) for the Canadian landmass south of 60° N. The data are georeferenced TIF images, one image for each day of the year.

More information about the dataset is available from the Map Library's data website.

Map Library gets Google Earth/Google Earth Pro 5.0

Stop by the library to try out the latest release of Google Earth 5.0. Several new features will enthral you with never seen before imagery. Dive into the ocean layer featuring photographs and videos of the deep sea. Travel to the bottom of the sea in search of shipwrecks, or marine life. Learn about endangered species, track animals and research facts that have been compiled by a number of scientists and organizations including NOAA, NASA, National Geographic Society, BBC, Monterey Bay Aquarium and many others.

Also new to 5.0 is the ability to go back in time and view historical imagery of particular geographical areas. A new clock button in the toolbar toggles a timeline controller that enables users to seamlessly view all imagery that is available for the area in the view’s extent.

Google Mars is the last of the newest additions, where high resolution satellite imagery (HiRISE imaging system) and 3D terrain of Mars replaces Earth. The layers available include Rovers and Landers, 3D Models, Terrains and more. Users gain a unique perspective of the planet, travelling through the eyes of the Mars rovers and other missions.

All of these features are available in the new Google Earth. For additional GIS features, try Google Earth Pro, also available at the Map Library.

Whitehorse Orthophoto Mosaic 2006

The Map Library has acquired a mosaic of the city of Whitehorse in Yukon. The image was taken in September 2006 and processed at a ground resolution of 25cm. The image is available in .ecw format with a size of 1.5 GB. This compressed format is compatible with ArcGIS.





This mosaic was received from the City of Whitehorse, Land Development Office in January, 2009.
