So the star below is a camera and the crosses are towers. The circles represent what area my camera can see. I need to remove from this circle the spots behind the towers that my camera cannot see. It would be roughly one degree. What is the best way to do this? I have tried a lot of different ways and did not seem to get the desired result.</P><P><IMG class="image-1 jive-image" src="https://community.esri.com/legacyfs/online/451881_pastedImage_1.png" /></P></BODY></HTML> Fri, 28 Jun 2019 21:14:45 GMT https://community.esri.com/t5/spatial-data-science-questions/using-a-point-as-an-obstruction-for-sight-line/m-p/649691#M1479 MichaelMcDermott1 2019-06-28T21:14:45Z Re: Using a Point as an Obstruction for Sight Line https://community.esri.com/t5/spatial-data-science-questions/using-a-point-as-an-obstruction-for-sight-line/m-p/649692#M1480 <HTML><HEAD></HEAD><BODY><P>buffer the points to make them polygons?</P></BODY></HTML> Fri, 28 Jun 2019 21:29:20 GMT https://community.esri.com/t5/spatial-data-science-questions/using-a-point-as-an-obstruction-for-sight-line/m-p/649692#M1480 DanPatterson_Retired 2019-06-28T21:29:20Z Re: Using a Point as an Obstruction for Sight Line https://community.esri.com/t5/spatial-data-science-questions/using-a-point-as-an-obstruction-for-sight-line/m-p/649693#M1481 <HTML><HEAD></HEAD><BODY><P>It is not clear what you are asking, you define the star as your camera, the circle the limit of what the camera can see and the crosses are towers then you say:</P><BLOCKQUOTE class="jive_macro_quote jive-quote jive_text_macro"><SPAN style="background-color: #ffffff;">I need to remove from this circle the spots behind the towers that my camera cannot see</SPAN></BLOCKQUOTE><P>What are the spots?
