Atoll to Google Earth problem

[hamody2005]

I have done an export of prediction from Atoll to Google Earth but When i opened it in GE there was a shift.

That means isn't identical to the actual site coordinates

In my experience, usualy problem from map we are using from planning tool. Check projection, and reff ellipsoid, GE using WGS 84. If all ok, then check your map version. Try using latest updated map.
Simple way to check : mark your position right now...then plot to planning tool & GE. So, you can compare which one is correct. For me, I prefer to GE and usualy give the exact location.

The Only difference is In Coverage Plot Not In Sites Position

Ok, just try to help with my experience (using NetAct/Asset) . Need detail data :
- Type of file exporting (BMP file, JPEG, GRD/GRC..etc).
- Resolution of Map
- How long of shift distance. etc

As far I know, if shift distance :
- about 50m , try with higher resolution Map ( 5m or even better with 2m res).
- More than 200m , there should be missing / wrong paramater. (projection, ref. ellipsoid etc..)
- Try exporting file with other type (BMP, JPEG, TAB etc) -----> trial and error, so you can find which type more accurate.

Thx Mr.Ledhie

about Map Resolution it's 100m
about shift distance it's up to 8km
about Other type of files Atoll doesn't ask for file type only KMZ file

Hi hamody2005, I think's there's mistake in setting while converting to KMZ. Also need higher resolution of the map. I suggest you can download in ASTER GDEM (search in forum) for free. If I'm not mistaken it's 30m resolution. Or, you can ask your company to buy higher resolution from map supplier if this for your work. I think now almost all vendor using 30m-20m res for region /country and higher resolution ( 10m, 5m or 2m) for detail coverage. Last, you can't use that coverage if shift distance up to 8km, it's uselless.

I'm having the same problem with the shift of the coverage. In atoll I can see good coverage in front of the antenna but in google earth the coverage is shifted by 50m. hamody2005 did you solved your problem

I will try to use 50m map

I still have the problem keep on touch

Ok I solved it. u should use same Degree format on atoll and google
