Hello all! I just started a new position mapping hog farms for a pork producer. The farms are located in Kansas, Oklahoma, Texas, and Colorado. My question is what would be the best projection to use when creating maps for the whole area as well as for the farms. I have done some thinking and thought that the large scale maps of the farms should be state plane or something like that. As far as creating maps for the entire area, I'm just not sure. Thanks for your help.

Lambert Conformal Conic or Albers Equal Area are often used for US maps.

Lambert Conformal Conic or Albers Equal Area are often used for US maps.

For USA maps, I like to use Albers, standard parallels 29.5 and 45.5. This projection is used commonly by the US government and others, so it makes it easy to match with existing sources. Set the central meridian to whatever is in your subject area.
