Former Member over 14 years ago

Here's an example of displaying a GPX file on detailed topographic maps:

I am the author of Gmap4 which is a 100% free enhanced Google map viewer. Since it runs entirely online there is nothing to buy, nothing to download, nothing to install. The detailed topographic maps are courtesy of the MyTopo company (USA and Canada).

Gmap4 can display these file types for anywhere in the world:
GPX files
KML files
KMZ files
Google MyMaps

You must first place your files online in order to view them with Gmap4. If you do not have your own website for hosting your files, then the free Google Sites works great. For tips on using Google Sites see p.14 of the Gmap4 'Help' file:
http://www.mappingsupport.com/p/gmap4_help.pdf

Gmap4 uses the new version 3 of the Google maps API (Application Program Interface).

For more examples and info please see the Gmap4 homepage:

Enjoy!

Recently Gmap4 was updated to version 4.1 and now includes a unique map-in-a-link feature that is worth mentioning. Anyone can now make a custom map and save their data right in a Gmap4 link. You do not need to save your data in a separate file such as a GPX or KML file. This may be the easiest and faster way for you to make a custom online topographic map.

To try out this feature:
1. Click Menu ==> Draw and Save
2. Click the map a few times to set draggable symbols and draw a line
3. Rightclick any symbol and select “Gmap4 display long link”

You can copy the link that is displayed, paste it into a new browser address bar, hit enter and your custom map will be displayed.

This feature also works on your iPhone, iPad, android and other mobile device. Remember, Gmap4 is a browser app and your browser has to be online. After you tap the screen to set some draggable symbols then tap a symbol and select “Action Menu”. The list of actions include two different ways to save a Gmap4 link that includes your data.

More information on this map-in-a-link feature can be found in the following three places.

1. What’s new page
