I can't find a good amount of information on creating a grid within a set boundary and using the intersection points as points for data. I work in the archaeology field and we dig shovel tests on a 50 foot grid. I am trying to figure out a way of creating a grid before entering the field, where each intersection point already has a distinct GPS point, and data can be entered via a database app in reference to each one of these points. Can anyone help me through this process?

I understand the fishnet tool, but not sure how to use the intersections and create points for each, and additional attributes to be filled in later. And how could I label each point based off of that grid system of x, y? For example, transect 1, shovel test 1.

I am not an archeologist, help me out here, when you say 50' grid I am assuming that's a polygon and you subdivide it into small squares? Or that's the size of one square in a big grid?

When you say you have GPS points, what do they look like? That is, GPS data wanders around, do you mean you have decimeter or better accuracy for a grid of points?

Writing a bit of code to generate a grid is the easy part for me. :-) Knowing what you want is the hard part.

If you have a picture or reference to a web site that would teach me more please post it and I will help you.
