Pin export/import differences
Hello BEAM team,

I'm finding that exporting a set of pins (as *.placemark) and then re-importing them into the same product is giving differences.

See fig attached. First set of pins 21-26 were generated, exported and then imported into the same product. The second set of pins 21-26 now in this product are the imported set and are slightly different.

Why is there a difference?

Hi Pauline,

The reason for this difference is that the geo-referencing is not 100% exact and the different way both sets are created.
When setting the pins in VISAT the pixel position of the where you have clicked is used to lookup the geo-location. This is easy and straight forward.
When the pins are read from the placemark file the geo-location is used as reference and the corresponding pixel position is searched for. And this is where the little inaccuracy comes from.

Ciao Marco,

Thanks for the reply. (I agree not 100% exact geo-referencing!)

The distance shift between the two locations of Pin 21 (for the product that generated the pin and then re-imported the pin) specified above is ~0.2 km, not so small given our pixels are 1x1 km...

Best wishes,
