Okay, here is my project, plans, and problems...
Project:
  I am a student currently interning at Roatan, Honduras at a dive resort.  One of the projects that I am trying to accomplish is to "map the sea floor" for the guest here.  The equipment I have to basically a dive computer that gives good enough depth reading so that it can be done. Then turn that into a 3D map.  I am using Arcmap 9.3.1 Student Edition.

Plan: Collecting Data
  Using my dive computer I am going to swim in lines to make a grid about 30 meters square.  This is a starting point to see if I will be able to do it.  My computer takes depth every second, I figure I can try and swim slowly to take as many measure along the path as I can get.
Plan: Using Arcmap
   My plan is to make a create a line and point shapefile, or maybe a grid.  Put points on the grid giving the data for depth.  Then putting it into 3D.

Problem:
   This project is pushing my limits of my understanding on how to do it and way do it.  I have always dealt with roads, or pre-made base maps.  So making a new map is very new to me.  If any of you know a good way to go about going about the project, could you give a basic outline on what to do?
Thanks,
  Corey
