Hello. I have study plots on the ground, each made up of an alpha-numeric grid. Since it is impossible to physically lay out a perfect grid in the field, the stakes are not perfectly aligned, and I am using actual grid-stake coordinates in GIS (ArcMap 9.3, but I may have access to 10 if needed). I want to create a polygon grid over these stake (point) coordinates in GIS, where lines intersect on the actual points. This is the first step...from here I need to divide each resulting grid square into quarters. I am a graduate student and something of a novice with Arc, but have tried to teach myself a fair bit over the past year. A novice-level answer would be much appreciated. Thanks!
