What is the projection of the map viewer?


The Map Viewer is not loading correctly

At the NWT Centre for Geomatics we have two different map viewers based on Geocortex Essentials software; namely Silverlight and Web ADF viewers.  The Silverlight viewer requires a Silverlight 4.0 plug-in for your web browser.  Some browsers have pop-up blockers that will prevent you from downloading the required plug-in.  Refer to your software documentation to enable plug-ins.  To optimize your viewer, see the minimum software setting requirements below.

Web Map Viewer Requirements:

  • -Microsoft Internet Explorer 6.0 or Mozilla Firefox 1.5 or higher.
  • -For best results a minimum screen resolution of 1024x768.
  • -High speed internet connection.
  • -Internet Explorer security settings may prevent this site from functioning properly. Please add this site to your list of trusted sites   
  •  under Internet Options if you experience problems.
  • -Firewall and Ad blocking software (pop-ups) may prevent this site from functioning properly. Please refer to your software
  •  documentation.

What is the projection of the map viewer?

Both map viewers are default Canada Lambert Conformal Conic on initial load up. Also known as EPSG (European Petroleum Survey Group): 42304 - LCC.  This projection is utilized because it best represents landmass at mid-latitudes minimizing distortion at small scales.  Within the Web ADF viewer, there is an option to change projection to Albers Equal-Area Conic, which allows a user to conduct large scale land measurements with greater accuracy than the Canada Lambert Conformal Conic.  Currently, the Silverlight viewer is not configured for "on the fly" changes in projection.
