Thanks Dan, The last link you provided was the closest. Unfortunately, I knew about this action but I was trying to avoid creating a new point each time. I have a few hundred points to "edit". I do not know the exact coordinates, only the coordinates of where the point was taken. I then wanted to plug in the distance and bearing from that coordinate to move the existing point to where the animals were located. As far as the coding, my experience is quite limited in that realm and I wasn't sure how effective it would be if all points need to be moved and each point needing a specific code based on the criteria.

I have a series of points along a transect that need to be projected various distances and directions from where the point was taken, each point being different. Real life example is when conducting deer surveys for distance sampling, a transect is driven and once a deer or group of deer is observed, a waypoint is taken, a laser rangefinder is used to measure distance, and a bearing is taken to get an exact location. How can these points be moved to show the location of the animal without creating new points if possible? Please, no coding answers.

Thank you to all who responded, I am confident all answers were correct, however; the clip function from Chris Donohue was the easiest for me to complete and resolve my issues.

The attached pdf is a portion of the polygon I would like to place the inside buffer. The yellow crosshatched area is the fill of the buffer, all I want to be able to do is to have the buffer where the white non-filled area is represented (100 M buffer) and not have the yellow cross-hatched area. I placed a scale bar for reference. I am not interested in the outside of the line, just interior. I am unfamiliar with Python and ring buffers. I am not sure on the licensing aspect of the software as it is institutionally owned.

I have read that to create a buffer within a line or polygon, use a negative number for the unit (e.g. -100 meters). However, in ArcMap 10.2 this is not allowed or in my experience it creates an error. I have a an area either polygon or polyline (I have created both to attempt the buffer) that I would like to have a 100 meter buffer within the boundary ONLY. When I create the buffer from the line example, it is 100 meters on each side (inside the line and outside the line; I only want inside) and when I create the buffer from the polygon example it buffers everything within the feature. Suggestions? I apologize if this has been mentioned before, I did not find it while searching for an answer.
