Secondly, are you using Differential GPS (or military grade)? Otherwise you're going to have much greater varation in your data feed than three inches....

This is the base station we use: http://www.trimble.com/agriculture/base-stations.aspx
During operations, 4 RTK Fix is required at all times, which I think is mil. specs.
This feeds to the auto-guidance system which then feeds back to my computer. Out of curiosity, will your tool work in offline mode? I didn't test it in field today due to local weather problems :( Knocked me down to a 7 hour day instead of 17 like yesterday!

P.S. Do you just want me to report once in ~2 weeks, or daily as possible?

So is this your farm?

A log jam preceeded by a long fart?
Compare this with the regular 300 LLs/day.

Extreme coolness.

In all honesty, my "app" is simply leveraging on Geo::Ellipsoid. As in, it simply works with the given Start and End Lat and Long -- online vs. offline is irrelevant. The code is literally:

...
use Geo::Ellipsoid;
...
$geo = Geo::Ellipsoid->new(ellipsoid=>'NAD27', units=>'degrees', distance_units => 'meter');

@Origin = ( $Lat1, $Long1 );
@Dest = ( $Lat2, $Long2 );
( $Range, $Bearing ) = $geo->to( @Origin, @Dest );

Entirely up to you.

Actually, approximately 291.7 LLs/day over the last 30 days.

Close, but no cigar.

In all actuality, the approximation I used is from trying to mentally recall the coordinates of our seed packaging lab. I work for a company that does precision planting of probably 30 different locations, each one being planted to one (or more) of 4 different crops, planting at each location anywhere from 144 to ~4000, 200-400 sq ft plots with 12-30 inch rows, depending on the crop. We do this all over a 5 state region for seed and chemical companies as well as universities.

No. There is a quirk in your table updates that means you only count 29 days of data between 00.00 and 08.00 UTC.
Perhaps you could correct this.

Incorrect.

Here is a mini case study of "One LL" between 50M and 60M:

7th June 19:00
          Total   Change
Today     142557  0
Yesterday 142364  193
1 week    141191  1366
30 days   136562  5995

I predict:
 
8th June 02:00
          Total   Change
Today     142557  0
Yesterday 142557  0
1 week    141191+x  1366-x
30 days   136562+y  5995-y
 
where x and y are ~193

The Visualisation Tool updates once a day.

Only once the current day's data is available do the databases update.

BTW, have I said I think you're a twit?
