THEN gives locations in two coordinate systems.

Both coordinate systems use a datum of WGS84. If you don't know what that means, don't worry about it. If you are transferring coordinates to a GPS, you should be able to configure it to accept either decimal degrees or UTM with a datum of WGS84.

The Tools section provides links to free online utilities for converting between coordinate systems.

Interactive Maps

THEN projects make extensive use of interactive maps that look like this. Note that this one isn't actually interactive but appears here only to explain the controls.

sample interactive map
Function What it does
1 This opens a panel that gives more details and a map legend. In the legend section of the larger (full-screen) map, you can turn boundaries and points of interest on/off.
2 Use this to zoom in. Note that on the larger (full-screen) map, you can also use the scroll wheel (function) to zoom in.
3 This is the Home control that brings you back to the initial map view after you have zoomed in/out and panned around.
4 Use this to zoom out. Note that on the larger (full-screen) map, you can also use the scroll wheel (function) to zoom out.
5 You can use this to select different map backgrounds.
6 This shows the map scale. The legend under the ruler might be difficult to see on the standard satellite imagery background. You can temporarily select a lighter-coloured background using function 5 above to reveal the legends.
7 Click this to see a larger (full-screen) version of the map in a new window. In this, you can zoom in/out using the scroll wheel (function).
8 You can pan (move) around on any map by clicking and dragging. With zooming and panning, you can get a good idea of the geographical context of each area (i.e., where it is in relationship to other parts of Whitehorse) and then return to the initial map view using Home (function 3 above).
9 You can click on features such as claim boundaries or points of interest to see more information.
