I’m pretty sure it’s a 15 minute quadrangle but the other two look good.dxu46 wrote:amk578 wrote:Oblivion wrote:Cool, your turn!1. Where is this quadrangle located?[img]https://ngmdb.usgs.gov/img4/ht_icons/Browse/IN/IN_Bloomington_156263_1910_62500.jpg[/img]

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?amk578 wrote:I’m pretty sure it’s a 15 minute quadrangle but the other two look good.dxu46 wrote:amk578 wrote:1.

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.dxu46 wrote:In that case, IDK.

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.amk578 wrote:The site I got this map from said this was a 15 minute quadrangle.

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)dxu46 wrote:In that case, 7.5 minute quads would technically be 45 minute quads.
