Today is the final post in my continental divide series. In earlier posts I have used the problem of computing the US continental divide as a vehicle for exploring data import, image... 更多内容 >>

Today's post in my continental divide series demonstrates the final computational step and shows one procedure for visualizing the Pacific and Atlantic catchment basins. In my previous... 更多内容 >>

Today, in part 5 of my series on computing the US continental divide, we'll look at a technique called minima imposition. Previously we looked at data import and display, the watershed transform... 更多内容 >>

Welcome to part 4 of my series on computing the US continental divide. Previously we looked at data import and display, the watershed transform and label matrices, and different kinds of... 更多内容 >>

In the previous post in this series on computing the US continental divide, we used the watershed function to find catchment basins in a DEM (digital elevation model). The result was more than... 更多内容 >>

This post is the second in my series on computing the location of the US continental divide. Today I'm going to look at the watershed transform, including how to compute and visualize it... 更多内容 >>

Today I'm introducing a series on computing the location of the US continental divide. (I was inspired to tackle this topic by Brian Hayes' blog post on the divide; thanks very much to... 更多内容 >>
