    Default Creating a polygon grid

    Dear GIS community - I am helping an archeology grad student construct a polygon grid (say, 1mx1m) over a map of her area of excavation. She tells me that this is how archealogical excavations are actually made, by laying down a grid and describing all items found within each cell - a sort of a spatial excel sheet. This database can be further split into different depth layers. I have been trying to figure out how to create such a grid using a starting point (which is at the North center of the grid in her case), and I've been unable to find any tool in ArcINFO 9.3 to do this... Would you have any suggestions, off the top of your head? Sincerely, Maria

    Hi, Maria -

    I'm not sure if it's quite what you need, but you might look at the Create Vector Grid function of Hawth's Tools:

    You could try the Create Fishnet tool

    Found in Data Management Tools -> Feature Class -> Create Fishnet

    I create grids for archaeological excavations at my work. I use ET Geowizard to do it.

    There is a tool called "Vector Grid" that works well. Fishnet I tried, but didn't like
