计算两个形状文件之间的距离，给定一个连接的poly线
我在确定考虑野火与排水距离的距离方面的最佳策略方面遇到了一些困难。这是一个 数据的屏幕截图（野火，流动线和最近的湖泊）。最终，我有兴趣根据从野火到湖泊的NHD流量线来计算距离。当然，我有多个湖泊（〜80），所以我也想限制约100英里的缓冲区的距离。
每个湖泊都有多个入口，因此需要连接的所有支流以及最短的距离（功能/方法将选择连接火和湖泊最短的支流）。
我将其发布在两个部分中，因为我对处理此问题的两种策略开放。我相信这可以在Arcgis Pro中完成。我已经研究了成本最低的路径方法，该方法可能对源是野火和湖泊作为源路径的最短距离有效，但不确定哪种成本路径方法更适合我的数据集（Shapefiles/lines） 。
我感谢耐心和建议。为了使它变得更有意义，我不仅仅是愿意重新提出问题。我不确定从这里去哪里，这就是为什么我决定发布的原因。

I am having some difficulty in determining the best strategy on approaching calculating distance from drainage considering wildfires. Here is a
screenshot of the data (wildfires, flow line, and nearest lake). Ultimately, I am interested in calculating the distance according to the NHD flow line from the wildfire to the lake. Granted, I have multiple lakes (~80), so I would also like to limit the distance of a buffer of about 100 miles.
There are multiple inlets for every lake, so all the tributaries that connect is wanted along with the shortest distance (where the function/method would choose the shortest tributary connecting the fire and lake).
I am posting this in two sections since I am open to two strategies of handling this. I believe this can be done in ArcGIS Pro. I have looked into the least-cost path approach, which could be valid for the shortest distance where the source is the wildfire and the lake as source path, but not sure which cost path approach is more suitable given my dataset (shapefiles/lines).
I appreciate the patience and suggestions. I am more than open to rephrasing my question in order for it to make more sense. I was not sure where to go from here which is why I decided to post.
