This will be hard to get work done efficiently.....My love of flying things is like a golden retriever chasing a tennis ball.....
More shots will follow as this unfolds......
Now is a good time to be doing that. Number of those flying is down nearly 90% and will take a long time to rebound.

That reminds me.?ÿ Several years ago we did a topo at a local General Aviation airport.?ÿ I have no idea why but the specs called for 0.2 foot contours.?ÿ We can do it but why.?ÿ Then the crew chief shot the top of the flag pole for elevation.?ÿ Forgot to remove that point and the contour lines went on forever seemingly.

I use .2' contours on runway work because the FAA specs call for a max of 1.5% max slope, and the transverse interval not to exceed 25'.?ÿ This way an engineer can easily see if there are 2 contours between the shots, the pavement exceeds standards.?ÿ At General Aviation airport's the max slope is 2.0%, so you could use a .5 contour interval, but then your majors are at 2.5' intervals.
