    Add an interactive topographic map (+GPS data) to your post

    Greetings,

    I applaud the Bogley admins for making it easy to add

    Holy cow - I saw your posts earlier today, and was a little skeptical - but seeing that KML file in action, that's pretty cool. I look forward to trying this out.

    Thanks Joseph.

    That is cool. It's like that rare moment when Spam turns out to be just the thing you were looking for and deeeeeeelicious!

    Thanks for the kind words.
    IMHO, rolling your own KML files is not that hard.
    Be sure to check out the Appendix in the Gmap4 Help file.
    Download those KML files and read the comments in them.

    i have looked at these also and i'm impressed. like kev, i too was skeptical but it looks good. i will try and play with it some more in the next few days.
    But if I agreed with you, we would both be wrong.

    This link will give you a map of Aukland, New Zealand and the surrounding area.
    http://www.mappingsupport.com/p/gmap...174.726563&z=9

    The map type that first displays is controlled by the "&t=" parameter. The above link does not have a t parameter so the default of &t=t1 is used.
    That default value causes the Google Terrain view to be displayed.
    Since the MyTopo company only has topographic map tiles for the USA and Canada, Gmap4 can only show you the standard Google Map views when you go outside of those areas.
    But you can still use Gmap4 to surf/display GPX, KML, KMZ, TPO and Google MyMap files for anywhere.

    For example, I found this KML file with the 2010 Tour de France route:
    http://www.mappingsupport.com/p/gmap...10/tdf2010.kml

    Future enhancement plans:

    Presently I am in the middle of adding trip planning features. You will be able to click the map and set draggable waypoints and routepoints. Then you will be able to download that info in a GPX file which you can either (1) upload into your GPS or (2) convert via GPSBabel into a different file format that you can upload into your GPS.

    After I turn on the first version of trip planning and start getting feedback, then I plan to make improvements/changes to the user interface. There will be a right click menu and various other tweaks. All interface suggestions go into a file and will be reviewed when I sit down to ponder such matters.

    After interface tweaking then I expect to work on the trip planning feedback I will have received.

    It looks like a cool feature..... curious to see how it works out on Bogley.

    ...and we're not talking about porn?


    Joey, very cool stuff you've got going on here. I'm going to need to update my skills and my GPS...

    Your future plans of downloading the gpx is a very helpful component.

    All of this is great, but is only useful when people use it (obviously). So it has to be as easy as possible, so they will WANT, to add it in. Don't get me wrong, it's pretty simple already....just stating the obvious.

    Keep up the good work!

    An excellent point, easy = good.

    Gmap4 is designed to work like Google Maps. Both Google maps and Gmap4 can be driven by URL parameters. For more info on the URL parameters that can drive plain Google Maps, see http://mapki.com/wiki/Google_Map_Parameters

    Both Google Maps and Gmap4 understand the following URL parameters: q, ll, z and t
    Since one of my design goals was to make Gmap4 work like Google Maps, I do not see the basic structure of a Gmap4 URL changing.

    Let's think about this. All Gmap4 really needs from a user in order to produce a map is one of the following:
    lat,lng
    Google MyMap key value
    URL to a KML, KMZ, GPX, TPO file

    Over at http://www.nwhikers.net the wizard behind the curtain added a "Gmap" button to the screen where you type your post. That button displays an input form where the user can enter/paste one of the above 3 things. Tom's code then builds the Gmap4 URL. That's about as easy as it can be. Just a thought...

    Ahh...there we go. Now that's easy.

    Edit: would you care if I PM you about a topo map project I'm working on and ask a few Q's??

    Thanks for all the kind words everyone.

    I just saw a post in the Google Maps developer's forum saying that markers no longer appear on Google Maps. I just checked one of my maps and 'tis true.
    Your track lines still appear, but markers do not.
    Google sez they are working on it.

    Kev (cirrus2000) posted a nice topographic map & GPS track. I was going to suggest those that are interested in this map thingy might take a peek at his map. It included markers with linked pics. But thanks to Google all the markers are now AWOL.

    Edit: The markers have settled their contract dispute with Google and are now back on the job.

    If you like maps, check out the new features in Gmap4. Remember, Gmap4 is a 100% free no-ads map viewer that can display detailed topographic maps. There is nothing to download or install.

    1. A powerful search feature has been added. Click Menu ==> Search. You can search on:
    * Addresses
    * Names of places and natural features
    * Latitude Longitude (Geocache format and many others)

    Gmap4 has been updated to version 1.8.3

    The present-day magnetic declination for the map center is now always displayed in the lower right corner. This value is produced using software from http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html combined with data from http://www.ngdc.noaa.gov/geomag/WMM/back.shtml.
    Since the magnetic declination is always changing, the older value printed on maps can be wrong by several degrees.

    I also updated my links page to show (1) reviews of Gmap4 and (2) sites that are already using Gmap4 to produce online interactive maps.

    Gmap4 has been updated to version 1.9.1 dated January 17, 2011. This version adds support for UTM coordinate grids. All UTM support in Gmap4 uses the WGS84 datum. This UTM support works worldwide. For more info on UTM coordinates see: http://en.wikipedia.org/wiki/Univers...rdinate_system

    (Pay back time: When you visit other outdoor-related forums, please do a search and see if Gmap4 has been mentioned. If not, it would just take a moment for you to pass the word along. Also, are you doing the social network thing? Consider saying something nice about Gmap4.)
