Gmap4 has been updated to version 2.2. The full list of changes is posted on the Gmap4 “what's new” page (see hompage link below). Here are some highlights.

First, Gmap4 can add labels to Google maps. The labels are built from the waypoint names in your file. Your existing maps will work with this feature, except KMZ files are not yet supported. Labels can be styled with your own HTML and CSS. The following link displays a GPX file that is hosted at Topofusion and displays with labels turned on. http://www.mappingsupport.com/p/gmap...&t=t2&label=on

To open Gmap4 with labels turned on, include this parameter in your Gmap4 URL: &label=on
To toggle the labels after a map is displayed click Menu ==> Label On/Off

You can style the labels with your own HTML and CSS. This label feature works with all the file formats that Gmap4 can read except KMZ files. Label support for KMZ files will be added in a future update.

Below is an example of a map I made with fancy labels. Note that (1) each label is clickable and (2) when you shift to an aerial map view then the labels acquire a solid background so the text does not disappear in shadows on the aerials. This map uses a delimited text file that is hosted at Google Sites.
(This forum is trashing the following link)
http://www.mappingsupport.com/p/gmap...&z=13&label=on

Second, a number of features have been added to the delimited text file format that Gmap4 can display. The section of the Gmap4 Help file titled “Delimited text files - Some details” has been completely re-written and now starts with a series of example maps that will let you rapidly learn the basics. If you want the most control over your map, this is the file format to use.

Third, the internet security features of Gmap4 have been enhanced. If you look at a file that causes Gmap4 to display a security-related message on your screen and you think that message is a ‘false positive', then please go to the Gmap4 contact page and send an email. Include the URL to the map (Menu ==> Show map URL) in your email.

Fourth, Gmap4 can now display files that include a '?' character in the URL for the file.

For more information please see the Gmap4 homepage: http://www.mappingsupport.com/p/gmap4.html

Enjoy!

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'.
http://www.mappingsupport.com/p/gmap4_help.pdf

Here are two links with more information if you are curious how this works:
http://www.mozilla.org/en-GB/firefox/geolocation/
http://support.google.com/gmm/bin/an...r=39894&src=cb

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.

The Gmap4 code has been updated to version 3.0. There are two new ‘big' features that many people will find useful.

First, Gmap4 can now display a new set of very high resolution USA topographic maps that (1) are a better quality image than the MyTopo maps, (2) do not have heavy watermarks obscuring part of the map and (3) do not have any ads. The link below displays a basic map of the USA. Zoom in to your favorite area (or use the ‘Search' feature) then open the menu in the upper right corner and select “t4 Topo High”.
http://www.mappingsupport.com/p/gmap....21875&t=m&z=4

You can also set the amount of hill shading you prefer to see on these new maps. Click Menu ==> Hill shading. And there is a new URL parameter (&hillshade=) you can use to set the hill shading in any Gmap4 URLs that you make.

A developer in California named Matt (http://CalTopo.com) produced these new topo map tiles from data he obtained from the USGS. Matt is paying out of his pocket to host these new map tiles on Amazon's cloud service. It is my great hope that the Gmap4 user community taken as a whole will be willing to make sufficient donations to pay its share of Matt's Amazon bill. The Menu button on the map has a ‘donate' link.

Matt's high resolution topographic map tiles should cover the states show in green on the following index map. I think the states that are not done yet are FL, LA, MA, MS, NH, RI, SD, VT and WY.
http://nationalmap.gov/historical/index.html
As the USGS finishes high resolution scans (660 pixels per inch) for the remaining states, Matt will be processing that data into tiles.

The Gmap4 ‘Help' file has more information on these new maps and also instructions for how you can report any problems you discover.

Second, Gmap4 now includes a trip planning feature called “Make a map”. You can now click the map to make waypoints, routes and tracks. You can download your work in a GPX file and then upload that information into many handheld GPS units. Of course you can also put your GPX file online and then make a Gmap4 URL to display your file. This feature works worldwide.

Gmap4's implementation of this feature lets you:
* Click once and create both a waypoint and routepoint
* Edit any data field (including GPS symbol name) that causes information to appear on your GPS screen

“Make a map” quick start:
1. Zoom in where you want to do trip planning
2. Set the map view you want
3. Click Menu ==> Make a map
4. Click a few spots on the map. Distance in miles and kilometers is reported in the lower right corner.
5. Right click any point
6. Click “Download GPX file”
7. Right click the URL to the GPX file and save it on your harddrive
8. Load the GPX information into your GPS

Each click you just made on the map sets a draggable (click-hold-drag) waypoint and routepoint. This is the Gmap4 default for trip planning.

For more information on these features, please visit the Gmap4 homepage and download the current Help file. The sections that describe these new features are marked “(New)” in the table of contents.
Gamp4 Homepage: http://www.mappingsupport.com/p/gmap4.html

I welcome your suggestions for improvements and any bug reports.

Enjoy!

Awesome work with Gmap4. Super helpful for a trip I've been planning recently.

One question.....is there any way to get more trails to appear on the topo's? Some major trails appear but most US Forest Service trail do not it seems. In the Bob Marshall Wilderness (Montana), the CDT (cont. divide trail) shows up, but the huge network of US Forest Service trails do not. This would really be a benefit if it was an option to show these.

Thanks for the kind words.

Here is a map showing a random spot in the Bob Marshall Wilderness and a couple of trails:
http://www.mappingsupport.com/p/gmap...7697&t=t4&z=15

The topo maps displayed by Gmap4 are simply scans of the paper maps. If a trail is not on the paper map then you will not see that trail with Gmap4.

Also, the 't2' topo maps presently do not show anything. Microsoft has cancelled the service that was displaying those low resolution topos. That will be fixed sometime within the next few days when I update the production code. The beta version of Gmap4 can display those same maps from a service run by the USA USGS.

Anyone is welcome to try the latest Gmap4 beta code. This link displays the default map of the world:
http://www.mappingsupport.com/p/beta/gmap4_464_beta.php

In addition to fixing the t2 topos, this beta code will automatically show phone-size buttons if you open this beta link with the browser on your phone, iPod or Blackberry. Remember, Gmap4 only works if your browser is online.

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
Note the tip about deleting the ll and z parameters from your Gmap4 link.
http://www.mappingsupport.com/p/gmap4_whats_new.html

2. Example page
Scroll down to the section titled “Your map data saved in the Gmap4 link”. The examples range from basic to advanced and give you a quick way to see some of the kinds of maps you can make with this feature.
http://www.mappingsupport.com/p/gmap4_examples.html

3. Help file
You can download the PDF file and search it (control-f) for the section titled “Make a custom map with Gmap4 and save it”.
