1. Where is this quadrangle located?
2. What is the contour interval?
3. What series is this quadrangle?
1. Bloomington, IN
2. 20 feet
3. 2.5 minute
Someone else can post.

I’m pretty sure it’s a 15 minute quadrangle but the other two look good.

In that case, IDK. How would you determine it? The intervals between sectors are only 5', after all, which is 1/3 of the usual 15' for 7.5 minute series. So...even if the degrees were bigger than the normal, wouldn't the multiplying factor be by 3?

The site I got this map from said this was a 15 minute quadrangle. I think the way to find it is just subtracting the far right latitude (86 30') by the far left latitude (86 45') getting 15 minutes, but I may be wrong.

In that case, 7.5 minute quads would technically be 45 minute quads. Did you get it from NSGS? If not, check the source again.

Yea I got the map from the USGS. And the sectors in a 7.5 minute quadrangle are 2'30" apart, not 15' so the multiplying factor would be 2. Also the Bloomington Quadrangle has a 1:62500 scale which is typical in 15 minute quads (but that's not a dead giveaway)

oh rip...it's been a while since i've touched a topo map :cry:

How many square miles are in a township?
