Comment on Tweaking the number of the MGRS layer by Ian

Ian — Mon, 10 Oct 2011 10:57:12 +0000

The MGRS grid looks like its based on WGS84. I’m doing some research in Vietnam using grid references taken off old maps that possibly used WGS60 grids, and it looks like there’s a varience of several hundred metres between WGS84 and where the WGS60 grid locations are.
Does anybody know of a KML file with WGS60 grids so I can use old grid references to locate places in Google Earth?

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.

Hi Barry
I need help with the following.
1. I need to plot markers in google earth approx 10 000 lat and longs from an XML format will be great if the icon can be changed along with color
2. For each marker I need it to be representative of a 250meter circle
3. When plotted will give me a form of coverage map
4. How could I then break it up into segments where if x numbers of markers exist in a segment then can color the region in as red , yellow, orange for high med low .
5. Appreciate your help on this

For Gogole Earth, can install

http://www.nearby.org.uk/google.html#9

then position the marker over the exact point. (its in the center of the view, so move the globe to position it) – read the location from the infowindow on that marker.

Move the globe so you over point “A” and rotate the view to look towards “B”. ie so you looking down the line. And the line is vertical on screen.

Now the compass star should be reading 227 (just about)

… its not for measuring angles on screen, its for showing which direction you are currently ‘looking’

@Barry – Thank you for the timely response. I guess I’m confused because when I draw a line using the GE ruler tool, for instance from point A to B in a S.W. direction, the tool reports a ‘heading’ of 227 degrees. However, this reports appears to conflict with the marks identifying heading on the compass…

@Jim,

Its ‘backwards’ as the the compass doesn’t actully rotate. The ‘N’ marker moves around the circle, and continues to point towards north. So number on the compass was showing how far from north it moved. ie the current heading.

Its difficult to explain in words, better to see it in action.

Just remember the number next to N is the current heading. (rather than the numbers measuring the angle of the ‘pointer’)

I’m a bit confused with the numbers included on this compass. I was under the impression the angle of bearing degree was normally measured in a clockwise direction from reference N, but it appears to be counterclockwise on this model?
