The Gmap4 production code is now version 2.3. This is the first version that includes special features for smartphones and other mobile devices.

1. Gmap4 can now find your location on the map. This service will use some or all of:
* Your IP address
* Cell towers
* Wi-fi hotspots
* Any GPS chip in your phone or other mobile device

Simply open any map in your phone’s browser and then select Menu ==> Findme. You can try this right now on your desktop/laptop just to see how it works. However, your desktop/laptop location will likely not be very accurate since in many cases only your IP address will be used.

You can also build Gmap4 URLs that will automatically run the Findme feature when the map opens. Simply include the parameter ‘findme=on’ in the Gmap4 URL.
Example: http://www.mappingsupport.com/p/gmap4.php?findme=on

Since Gmap4 uses the Google maps Application Programming Interface (API), this feature only works if your phone’s browser is online to the internet.

Also, because Gmap4 is a web application, you do not need to download or install anything in order to use Gmap4 on your phone. To open Gmap4 on your phone:
A. Open your phone’s browser. (Remember, that browser has to be online.)
B. Do a web search for Gmap4 - the first hit should be the Gmap4 homepage
C. Select the link just under the homepage title. That link opens Gmap4 and displays a map of the world.
D. Select Menu ==> Findme

Of course you can save the Gmap4 URL as a bookmark in your phone’s browser.

Gmap4 does not save your location or report it to anyone. For more details, please search the Gmap4 Help file on ‘mobile’.

Here are two links with more information if you are curious how this works:

2. You can turn off the coordinates in the lower right corner

Turning off the coordinate display in the lower right will let you see more of the map. You can toggle that display by selecting Menu ==> UTM - LatLng - Off

To open Gmap4 with that display already off, include the parameter ‘&coord=off’ in the Gmap4 URL
Example: http://www.mappingsupport.com/p/gmap...e=on&coord=off

3. Tweaking the mobile interface
Gmap4 is not a ‘native’ app for your phone. Instead, the exact same code that runs in the browser on your desktop/laptop also runs in the browser on your phone. Amazing! But this means my options for improving the interface when running on a phone are somewhat limited. What I can do fairly easily is add buttons. However, each button would cover part of the map.

Question: Are there any features of Gmap4 important enough that they should have their own buttons? One obvious candidate is the ‘Findme’ feature. Any others?

4. The MyTopo maps now display ads in one corner. That was not my idea!
For example, this map shows part of Yellowstone National Park:
http://www.mappingsupport.com/p/gmap...2396&z=14&t=t2

The Trimble Company now owns the MyTopo maps. As the 'price' for being allowed to continue displaying the MyTopo maps at no cost, Gmap4 must display Trimble's ad images when the MyTopo maps are on the screen.
