The area of a circular buffer is a monotonically-increasing function of buffer radius (on a planar coordinate system anyway). So a simple search strategy can find a radius R such that the area of the buffer of radius R clipped to polygonal region A is (up to some tolerance) s. The simplest search algorithm would just be a binary search. Start with two ...

Try something like this. Use the Generate Near Table analysis function. This gets you the distance to the closest line on the Polygon as in your diagram. Join this information back to the the original points file. Build the new point based on the angle and the distance you now have in the original point layer. Something like this in the field calculator ...

Just to add to the already given great answers, you could also use the Select by location tool from the Processing Toolbox to give you more options on how you want to select your objects:

Try changing the buffer method from Planar to Geodesic Arguably, in such small scale features this shouldn't change much, but stranger things have happened before. Here's a case where I buffered some points in a geographic CRS with a planar buffer of 250 meters and displayed on a projected CRS. Using a geodesic method solved this issue for me.

When you run Polygon to Raster, under Value field you need to specify "distance" (if you haven't changed the default of Multiple Ring Buffer). Then, the new raster will have as many unique values as there were unique distances, specified under field Value. This Value field is the one to reclassify, but until you run Polygon to Raster, ArcMap won't be able ...

It's almost impossible, due to the position of the points. You can create buffers of 400km2, but points closer to the coastline will always have a smaller area compared to the ones further away (>400km2). The only thing you can do is do perform a buffer analysis on the points and clip the created buffers with the coastline feature afterwards.

Answer: When adding XY data in NAD27 Decimal Degree Coordinates (from a .csv file The buffer distances will be inaccurate to the basemap if the basemap is in a different GCS (Geographic Coordinate System) or PCS (Projected Coordinate System) Solution: display XY data from .csv file export data by right-click on "filename.csv Events" select data then ...

Assuming you are only interesting in visualizing these colours and not worried about trying to encode the "distance" into the road network why not simply run the Intersect Tool? Intersecting your road network with your polygon buffer layer. I'm assuming the buffer distance is a field in your buffer layer. By Intersecting these two layers you "chop" out the ...

If you have an Advanced ArcGIS license, the Near tool will add the closest Point as Near_X,Near_Y coordinates to the input attribute table. The Make XY Event Layer tool can be used to create a Point Layer from the Near_X,Near_Y values. You must copy the point layer to disc to preserve it because it is only in_memory, FYI. Another option is found in the menu ...
