I have a shapefile of points with a variety of attributes, the relevant ones being "ID", "area", "lat", and "long". Such as... The lat/long coordinates are always the SW corner of a plot and the area varies from 10 to 50 km-sq. Each plot is always a square. I would like to make a polygon shapefile from the point shapefile that displays the entire plot to be able to clip other features. To look similar to... This is a one-time operation in this case and I would like to do it in Arc (I'm using ArcMap 10.2.2) but would be willing to use R if it is easier. Maybe it would be easiest to calculate the coordinates of each corner first? I have found answers similar to my question in:
- Createing polygon layer from point data using QGIS?,
- Creating polygons (squares) from point using PostGIS?, and
- Calculating coordinates of square x miles from center point?,
but not quite what I want and using different programs.
