Gmap4 has been updated to version 2.1.5 dated September 14, 2011. For a full list of the changes in this version please see http://www.mappingsupport.com/p/gmap4_whats_new.html

Remember, Gmap4 lives in the cloud and does not require you to download or install anything. Anytime you view a map with Gmap4, you automatically will be using the most recent version.

The big news is that you can now strap on a personal jet pack and fly around in 3D anywhere in the world. (The Gmap4 Search feature is a useful way to zip you to the spot where you wish to begin flying.) This feature runs Google Earth in your browser.

You can zoom in and fly over any map that has a GPS track (or other data) and see the world in 3D. No sweat, no bug bites, no blisters.

All you have to do is download the Gmap4 Help pdf file dated September 14, 2011 (or more recent) and search for Tips for flying. Anyone can quicky and easily learn to fly with just a mouse by taking a quick trip through flight school by reading those tips. Those tips give you step-by-step instructions that will show you how to fly over the John Muir Trail in California starting from the summit of Mt. Whitney. This is ability to fly with a 3D view is easily the coolest feature in Gmap4.

Gmap4 Help file: http://www.mappingsupport.com/p/gmap4_help.pdf

For most people this updated version of Gmap4 works fine. However, a few people have reported that all they see when they try to use Gmap4 is a blank screen. If you are having trouble viewing maps with Gmap4, then I have a favor to ask. In addition to updating the code I also put together a short list of easy things that you can do to try and get the latest version of Gmap4 working on your system. Heres the favor: Please download the Help file and search that file for tips on flying. Near the end of that section you will see a heading that starts Background.... That section gives you a peek under the hood and suggests several easy/quick things you can do to try and get the current version of Gmap4 working on your system.

Some of those suggestions have worked for others, so I hope if you are having problems that you take a few minutes and give them a try. And if nothing else works, then the last suggestion gives you a link to the prior version of Gmap4 that does not include the new Earth feature which seems to be the source of most of the problems.

In addition, the directions feature has been re-written. Right-click the map and then click either Direction from here or Direction to here. After the route appears, you can drag it to make changes. You can build a Gmap4 URL that will open with the directions panel displayed and the destination filled in. This will be useful for helping people obtain directions to a meeting spot. Search the Gmap4 Help file for Tips for using directions.

Also, information on how to donate has been added to the Action menu and the Gmap4 website.

Enjoy!

Gmap4 has been updated to version 2.1.6 dated September 17, 2011.
Homepage: http://www.mappingsupport.com/p/gmap4.html

Reminder: Since Gmap4 lives in the cloud (1) you never have to download or install Gmap4 and (2) you are always automatically using the latest version of the code. But if Gmap4 does not seem to work then please clear your browsers cache and try again. To see the Gmap4 version number you can click Menu ==> About on any map.

This update fixes the blank screen problem that some users experienced after the September 12th update. If you experienced that problem, then please try Gmap4 again.

In order to use the new 3D Earth view, your computer system needs to have the Google Earth browser plug-in installed. The Gmap4 code now checks to see if your system already has this plug-in installed. If your computer system does not have this plug-in installed, then you will see a message telling you that and a link to Google where you can download the plug-in if you decide to install it. If you decide to install the plug-in, please follow the instructions in that message. You need a broadband connection and a reasonably modern computer to use the 3D Earth view.

Also, your security software might ask you to give permission before this plug-in will work.

If you decide to not install the plug-in, simply close the message window. You can continue using all the other features of Gmap4 except the Earth view.

Joseph...Thx for putting this together. It will take someone with my lack of cyber skills a while to get the hang of, but I will.
I have an unrelated question that I can't seem to get an answer to, maybe you can help. GE used to show springs and creeks like on the topo maps. I can't seem to get this feature activated, even though I've tried all the layers and options. Am I doing something wrong, or is this feature no longer available?
Thx...Steve

I'm a poor one to ask since I do not use GE much.
Suggest you post in the GE user group

Here's a response I got:
You could try, in the Layers pane, selecting More -> Water Body Outlines. Alternatively, the usgs placenames is a great resource. Their kml is here: www.geonames.org/kml/feature-networklink.kml

Tried the water body outlines, no go. Can someone translate the rest of the response?

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/gmap4.php?...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.
http://www.mappingsupport.com/p/gmap4.php?...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!

Joseph, I was just trying to use it yesterday and the map is still there and scalable/panable ( http://www.mappingsupport.com/p/gmap4.php ), but none of the menu features are active (i.e. Search, map type etc)

This my home computer and there are no odd firewalls or filters.


Well that is certainly an odd one.
How about clearing your browser cache and trying again.
Also, try another browser.
If that 'puter uses IE6 you may be SOL.

Windows 7 and IE8. I cleared everything and still no go, there is just a beige dead space above the map

but it works great in Firefox, so no worries. Thanks!

Try telling IE8 to run Gmap4 in "compatibility" mode

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 phones 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 phones 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 phones 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 phones 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/answer.p...9894&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/gmap4.php?...n&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/gmap4.php?...p;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/gmap4.php?...amp;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 Amazons 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 Matts Amazon bill. The Menu button on the map has a donate link.

Matts 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.

Gmap4s 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!

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”.

The service you offer is VERY nice !!! Thank you.
 
Is there a way to overlay BLM maps?
 
Or, does anybody know of a site with BLM boundary maps? Don't really want to drive to the BLM office to buy more maps when I just want an approximation of some boundaries.
