Tree leaves are a changing, so going to-hopefully in the next few weeks be able to run the topo of an old subdivision in my area that -hopefully - will break ground next spring, my company has been working on this site for over 30 years getting the thing approved (mostly owners fault) then appealed, then waiting for house market to change, then the concom plans expired etc. but i want to update the topo on the site with something that is more current then the STADIA topo done over 30 years ago......and waiting for the leaves to fall so i can get more "ground" shots. like how pix4d uses a double grid now for topo flights to increase accuracy.
minor isssue i have had with the ph3A is it hasn't run the updated firmware that was just released, even though i have followed all the instructions- it just won't update.
for those that do not know what stadia is..you have a 25' long "rod" and a level .
thru the level eyepiece are 3 lines with the crosshair,... middle line is the distance you read on the rod which says it is 5.62 or 15.88 or whatever distance it is from the ground to "level" on the level, then you subtract the bottom line number from the top line number to get the distance shot...
example, crosshair reading 5.62, top reading is 6.24 bottom reading 5.0 so the distance the rod is from the level is 124' (if i remember correctly we have not done a stadia topo in a couple of decades....)
