it is certainly true that I have not seen most of the information that has been posted on this forum!
it really does not matter who put the most effort in finding out ground levels. if they are wrong, insufficient efforts were invested.
I just had a look at the kml file you submitted, and you are using 45 points to define your polygon… that is ok, but how many reference points do you use for the elevation of each of the relevant buildings (e.g., where the snipers were located), the podium, bleachers, hydraulic lifts (not only the one I use as end point reference for the 1st bullet, witnesses, tents, etc, etc)…
I never have seen your model, but I am extremely sure you do not use the appropriate elevation for each of the points of interest!
furthermore, you always refer to whole units of feet.
where relevant, I use centimeters.
1 ft a bit more than 30 cm.
whole ft is a very inaccurate way of measuring!
small deviations in cm make smaller deviations at larger distances, but if you start with af ft off, you get way out of target…
as I explained in an earlier post today, in the kml file I shared two days ago, you can find a section “horizontal planes” which visualize the terrain elevation levels at centimeter level…
have a look at
I would really appreciate it if you could confirm that you do not use the appropriate elevation levels at the points we discussed earlier!
