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
I have not done this type of project before but it strikes me that you want to create a 3D Point file and add the data you collect for each point (do you have a means of swimming in precise lines, since I assume currents etc may make the mapping in-accurate to some degree [it depends how accurate you need to be for this mapping project]) you can use this data to make a DEM (Digital Elevation Model).
