Help with template for geophysical grid
Hi, this is a first posting in a long while and I hope that this is in the right place.
I have what I think is a simple problem, but at the moment I'm not able to get my head around what I need to do. I need to make a database app for iPad that will allow a user to collect a data point on a grid, and the iPad will effectively tell the the user what grid point he or she is at. to start off the grids will be standard 20 x 20 grids, and the user will begin at point 1,1 and move to 1,2 until the row is completed. they then move to row two, etc.
it would be helpful to add a designation letter for the grid as the data is collected...ie., the user will fill in a form first, asking the user to supply a site and grid reference. later i can add the size of the grid and all.
I know this is asking for a lot, but I would have thought that there would be something like this out there fairly readily...but i can't find anything.
thanks very much
