Why is projection important?

"The Earth is a sphere (or more correctly a spheroid), and a globe is the best representation or model of the Earth's surface. A map, on the other hand, must represent as accurately as possible the 3-dimensional Earth on a 2-dimensional (flat) surface. In producing a map it is important to ensure a known relationship between true locations on the Earth and the corresponding points on the map. Therefore, the construction of any map must begin with a map projection ..."
 From The Atlas of Canada website - http://atlas.nrcan.gc.ca/site/english/learningresources/carto_corner/map_projections.html

Another good introduction to projection is here: http://en.wikipedia.org/wiki/Map_projection

Why I cannot see the WMS service in Preview?

The WMS service is based on ISO theme categories, meaning that all vector data related to that theme will be stored within that WMS service.  For example, the Ecological/Biological theme will contain species at risk data, wildlife habitat zones, and fire history.  Most of the layers have been turned off by default because it is too cartographically complex to represent them all at the same time.  To preview the WMS service, either use our Spatial Data Warehouse Viewer or utilize your own GIS software such as Google Earth.

Where do I reference or view WMS serivce Metadata?

This is how we organize our data; A link to our WMS services can be found within our map viewer within the advance tool bar.  You will have to click on the layers within this ISO theme to find the specific descriptions for the individual layer data sources. To learn how to reference a WMS go to http://www.opengeospatial.org/. Many different methods of citation formats are availible. 

All of the above information can be reached from our Geomatics website from here. http://geomatics.gov.nt.ca/wms.aspx.  For Example, the ISO theme that you are referencing is Ecological/Biological will be found here  http://geomatics.gov.nt.ca/wms_chartop.aspx?i=1.  Each layer which the Metadata tab will have a descriptor & credit.  The main introduction of the WMS will have any data sharing agreement that must be followed.
