Mapping Glossary

Feature types
Map features are either point, line of polygon. Depending on the map scale, a feature may appear as a polygon on a large scale map (1:5,000) but as a point on a small scale map (1:100,000)
This should not be confused with topography (elevation). Topology is the mathematics of relationships. In the world of GIS, it refers to such relationships as adjacency (e.g. two property parcels next to each other), connectivity (i.e. a road segment joins at an intersection) and spatial overlay. We can overlay a polygon layer (e.g. park) with a distribution of bird sightings (e.g. points) and determine how many and which sightings occur within the park.
A map can be deconstructed into a series of layers.

Nova Scotia Solar Resource Maps

We have added solar resource maps for the Province of Nova Scotia, Canada, showing solar energy for the month of July for the 2007, 2008 and 2009 calendar years. See the maps.
