Where to see error improvement
#1
We are attempting to bring online a detector in a fairly underserved region of the world.  As far as I know it would be at least 1000 miles from the nearest detector.  I'm interested in how this would affect the quality of measurement accuracy in the region.

Can someone point me in the direction of:
  • Where (geographically) would you expect the greatest improvement of accuracy (closer to the new detector)?
  • Is there an explicit measure of error that would be expected to improve and where in the dataset would I find that?

Thanks.

From the nature of your other posts, I might suggest you review all the Blitzortung documentation.  No, there's no 'explicit measure of error'.  It's an assumed 'deviation' of location for each stroke for each station.  It IS displayed for each stroke in various map view configurations.  It is a computed, assumed error based on a large number of variables mixed with hard data....
 
Strokes must be detected before they can be located. Assume for simplicity that it takes a minimum of 4 receivers to 'detect' a stroke, and then a 'location' computation can begin... the error here will be significant. Especially at a distance. In actuality, that number would be a minimum of 8-14 stations required.

Assume you are in a location surrounded by stations, let's say 3, in an arc, north of you.  They're all 1000 miles from you.  In this scenario, NO strokes can be detected, and therefore  located, in your vicinity, by those three stations.  They're probably receiving them, and sending them, but the 4th station is missing,... You... so all those signals are ignored at the computing server, in this example, requiring 4 stations.  Suddenly your station comes online... the missing 4th.  Suddenly that undercovered area lights up with lightning strokes, and they are located, with some degree of 'deviation' of actual ground point.  A fifth station would decrease that deviation probably... and a sixth.... etc. 
So, to start with, just adding your station increases coverage area, and locating potential, with perhaps a large deviation error, but at least they're recording now, when the area was 'naked' prior to your activation...  The more stations which receive and report an impulse theoretically increases the accuracy of BOTH 'stroke totals' and the accuracy of location.

Your IP at registration indicates New York.  Any station located in New York is much closer than 1000 miles to any neighbors.  What's going on?

I have a family member who lives in the Amazon river delta region. Thanks for your response.

If they can get stable power there, a good station would help a LOT of regions!
