Tool for analysis coverage on Google Earth

[jackkarpar]

i think this is because he forgets the earth is round, and the distance between two points should be converted to great-circle distance.

About the distance, this happened after the changes on Kml sources from google earth.
I still do not have time to check the problem that caused this error in the distance.

ps: i need one more rep to become a member, help please.

Hi,

Please, correct me if I'm wrong in the formula.

y = (Math.Sin(((Azimuth / 180) * 3.14159265358979))) * (Distance)
x = (Math.Cos(((Azimuth / 180) * 3.14159265358979))) * (Distance)


DeltaArcoLatitude = (y / 1852) * 60
DeltaArcoLongitude = (x / 1852) * 60

Hi,
thanks ,good job

legend is not visible!!

Hi, it seems that kml display polygon by lat/lon track, so we can draw from the start point (site location) to the next, and so on:

Formula:	lat2 = asin(sin(lat1)*cos(d/R) + cos(lat1)*sin(d/R)*cos(θ))
	lon2 = lon1 + atan2(sin(θ)*sin(d/R)*cos(lat1), cos(d/R)−sin(lat1)*sin(lat2))
	θ is the bearing (in radians, clockwise from north); d/R is the angular distance (in radians), where d is the distance travelled and R is the earth’s radius

Hi,

I'll fix this problem soon.

Tks,

Nice tool. Do you have sample files for WCDMA that I can test with?

Hi,

File attached.

PS: File from PCHR logs.

Not sure if I have done this correctly.

I used your files & managed to plot the sites & I can see the Legend.

So how to I display the coverage profile for a particular site or sector????

Hi,

It's very simple, see the figure below.
If the sectors don't not appear into the google it's because the tool does not find them in the database. This case, check the statitics in propagation analyser.

Dear all,
I checked this tool on Huawei RAN12 (3G) and it's working fine. Here is the analyze result;
