Great work!

However when I run it with version 3, it seems that the zip library is not enabled.

I get a fatal error with Call to undefined function gzcompress()

Any idea how to enable it.

I got your online kml version to work, but I’m having problems seeing the MGRS grid in the offline version. I can verify that my AppWeb server is serving the grid_mgrs.kmz.php file by browsing to http://localhost:8082/offline_nearby/grid_mgrs/grid_mgrs.kmz.php and it prints “Please zoom in to plot GridLines 1 “. Then I add the same URL as a network link in Google Earth. The link shows a green dot for “connected” but when I zoom in to plot the gridlines, the dot turns yellow and no grids ever get plotted.

I followed the above instructions, except I had to change all references of ‘Mbedthis’ to ‘Embedthis’ in the conf file, and I didn’t have to copy the php dll to the /bin directory because it was already in there. I suppose AppWeb Server has changed a bit since this article was written.

Thanks for your work on this.

I have noticed that if I try and edit the color or width of say the 100km MGRS/UTM Grid lines or edit the size of type in the lables folder, it breaks the program “MGRS Gridlines by Nearby.org.uk” and I have to load it again into Google Earth. Of course I see the “Edit limited to part of Multi Geometery collection” notice, but then whom am I to not try and see what I can change to the way I want something to work? Why can I only edit the firrst item? Yes I am whinning, with out whinning nothing will change….hahahah. Really thanks for making this in the first place, No, Really thanks…

Hi Barry, I have installed the appwebserver with no issues. I have loaded the network link but I cant get it to work. All I get is an error msg. Any assistance would be greatly appreciated

@Bruce

Yes you can run this on your own machine (the same machine that is running GE) – I built and tested it on my Laptop

Does this have to run on a server or can I run it on my computer (WinXp)and have the MGRS grid load correctly in Gooogle Earth Pro?

Do you have some suggestions or requested changes for appweb. We’re doing 3.0 now and would love to make changes to make this neat solution work more easily with appweb.

The UTM and MGRS layers are already conversions from British National Grid (and Irish Grid).

Its all about the maths, if you can get a coordinate conversion system, then it should be possible.

Its slightly different for simply a projection, as its still lat/long based system, just how the ‘grid’ is distorted.
So if you can get a conversion between lat/long and absolute position on a projected map then it should be possible by using that conversion backwards. (basically get the php source to conversion on the Australian government site here)

Already a great implementation.

Any idea how to implement a similar project for dispaly of other projected coordinates specific to country’s grid. I require it for a project to display Lambert Conformal Conical projection. Regards.
