Gmap4 Example Maps
Each map is created by specifying one or more URL parameters when Gmap4 is launched. The five URL parameters understood by Gmap4 are: q, ll, z, t and refresh. You can read more about these URL parameters, their allowable values and their default values in the Help file. These maps open in this same window, so use your back button to return to this page.
Gmap4 map of USA and Canada
This map shows most of the USA and Canada. Zoom in on the USA anywhere using your mouse wheel or the
map control in the upper left. To pan the map: Click-hold-drag. Keep zooming in until the scale
line in the lower left says "1 mile". Open the menu in the very upper right and select MyTopo. You
are now looking at the USGS 7.5" topographic map. Keep zooming in for more detail.

Gmap4 map displaying data from a GPX file hosted on Google Sites
KML, KMZ, GPX and TPO files can be placed online using Google Sites. This is a free service from Google.
The following map shows a GPX file containing the GPS track of a hike in the Washington State Cascades.

Gmap4 map displaying data from a Google MyMap file
KML files can also be placed online as Google MyMaps.
The next map is an example of a KML file that was 'imported' into Google Maps and saved as a Google MyMap.
The file contains the GPS track of a different hike in the Washington State Cascades.
You can use Gmap4 to display any Google MyMap simply by substituting the unique 'id'
Google assigned to that map into the following link.

Gmap4 map displaying a small 'live' map in a trip report
If you enjoy filing trip reports describing your latest hike/climb/bike/ski/paddle trip then of course you could include a
link to a Gmap4 map in your report. But even better, if the website where you file your report allows iframes,
then you can include a 'live' map right in the body of your report. This 'live' map can be as small as
400 pixels by 400 pixels. Here's an example from a site in Washington State popular with hikers.
Scroll down just a bit for the map. Since this map is 'live' you can pan, zoom, play with the
menus, etc.
