I have a problem with buffering and impact that land masses can have on distance.
We have SAR stations with vessels that have a 50nm action range to them. Now, Yes, we can draw a 50nm buffer around but we also wish for GIS to take into account (just like a vessel, in contrast to an airplane) that the 50nm range must go around land masses.
What ArcGIS tool could I use to fulfill this request?
I attached an image of my question.
From your screen shot it looks like the Buffer tool was used first with 50nm.
Then the erase tool was used to remove the land/shore boundary from the resulting buffer.
Good afternoon,
Yes, Created a 50nm buffer around one of our SAR Stations. But then used the simpler ‘Clip’ to remove the buffer over the land mass.
What my question is that, as a vessel needs to divert around land mass, obviously, the range of 50nm for the buffer gets shorter. I want to know if ArcGIS has a way of doing that for you.
Right now, I take 10-15 paths with the ‘measurement tool’ and them simply remove the vertexes that fall outside of that range. A very time consuming task… as I have over 200 stations and ranges (with also intersect with each other) to do.
Thank you.
