comment Using Latitude and Longitude with SRTM3 DEM file
Not sure to be honest, Just been playing around with trying to split a 1 dimensional array into a grid

Yep So from my understanding the file is 1201 x 1201 grid resulting in an array of 1,442,401 measurements. It is sampled at 3 ac seconds, dont know if that is important? Im just struggling with how to calculate which position I need to read. My current best guess is ((1201 * 0.456) * 1201) + (0.434 * 1201), but that doesn't seem to give the correct value.

Yes doing it from scratch, mainly as the data will need to be on a website. I have looked at using Google's elevation API but find the usage restrictions are quite light. Also I figured it would be a good challenge.
