Please read all of these notes before using the interactive map!
We are using this interactive map a little differently from how GPS Visualizer intended it to be used. Rather than drawing tracks on it, we are using the tracks to draw region boundaries. That is why the right sidebar says Tracks rather than Regions. PARK locations are shown within each region as a flag. Mouse over the flag to see the hike name. If hikes share a common trailhead, you’ll see only one hike name for a given PARK location.
The initial presentation of the map is at maximum scale so the first thing you need to do is decrease the scale by selecting your region of interest. You select your region of interest from the Tracks/Regions sidebar by placing the cursor over the next to the region name. When it is over the , the cursor will turn into a cross. Then click the left mouse button. Notice that the region boundary lines are the same color as the region name, though sometimes this is difficult to see.
If necessary, change the map with the map control in the upper left corner to your area of interest. The map control is the standard Google map control that you can use to zoom in, zoom out and move the map up, down, right or left. Other ways to manipulate the map are to place the cursor on the map and hold the left button down and drag the map up, down, left or right. Additionally, you can place the cursor on the map in an area of interest and double left click to expanded the map around the cursor. Double right clicking contracts it similarly.
Placing the cursor over a region name in the Regions side bar will cause a label to appear on the map for that region. Successive clicks on the region name in the Regions side bar will turn the region’s boundary lines off and on. When they are off, the region name is gray.
If desired, the Regions sidebar can be moved. Place the cursor over the gray bar on the top of the sidebar, hold the left mouse button down and drag the sidebar to where you want it.
You can also change the “background” for the map from the initial OSM (OpenStreetMap.org) to any of the other choices, which change from time to time. Some are topo maps; others are aerial maps.
Requesting an Update
Updating the map contents is in part a manual process, so new PARK locations aren’t automatically displayed. Use the Contact form under the Communications menu tab to request a new region or an update of the PARK locations.
