Subdividing a large, complicated shape

    A large, unruly, complicated shape with millions of nodes is causing our system to slow down too much. I'm trying to find a process or tool that can subdivide the shape without losing its integrity. I'm struggling to find a way to do this quickly and efficiently...not manually. Thanks!

    Hello James,

     

    A common way is to build a (suitably sized) grid over the large object and split it. Processing will be much quicker and the only real downside is that if you wish to display the polygon with an outline style, the grid-based elements will be visible. I've used this technique for many years on things like mobile telecom coverages and it generally works well. You can automate the steps of the process with a MapBasic program.
