Squirrel Problem
http://jsaezgallego.com/GlobCover_maps_squirrel/The answer is: obviously not. But, another question arises, 这个问题不太容易回答:如果一只松鼠必须从西班牙北部走到南部, 尽可能少地接触地面:它会朝哪个方向走?
The answer is not trivial, and it is answered here!
The project consisted of the following steps:
1. Download data from the internet. 该数据由GIS信息组成,用于确定一块土地是否为森林, a river, a man-made construction, and so on.
2. Create a path matrix. The squirrel takes one step at a time. 就栅格图而言,这意味着我们只能从相邻像素到达每个像素. Think of it as a huge spare matrix.
3. Optimize the path. 计算从西班牙顶部到底部的最短路径. 每个部分的成本是像素值,所以穿过森林不需要任何成本,而任何与水有关的东西都不可能穿过.
4. Visualize the solution as an interactive map.
