I was having trouble figuring out why ST_Area area calculations weren’t working correctly in R
I was having trouble figuring out why ST_Area area calculations weren’t working correctly in R. The reason was I was dumb. For ST_Area to work correctly you have to use an equal-area projection, such as Universal Transverse Mercator or Consus Albers. Projections that distort area won’t work, if you want to use such projections, you have to reproject the data before calling ST_Area.

Meet Pam Byrne and John Huerta of West Virginia
Ownership of land comes with incredible benefits. If you treat your land right, it can provide you so much value in return. However, it also comes with its challenges. Without the proper care and technical expertise, maintaining large areas of natural landscapes quickly becomes a slippery slope, full of uphill work and hidden surprises. The couple was excited to own their acres of incredible wilderness right in their backyard. They wanted to do as much as they could to promote the health of their woods and its native species – without making it a full time job. And as with other landowners, invasive plants and animals are of growing concern for the two as well. Pam and John are well aware of the thorny bushes and invasive insects slowly eating away their natural landscapes. They quickly realized they needed help to understand their woods better and how to treat them for improvement. So when Pam and John learned about the Family Forest Carbon Program, it wasn’t long before they became early adopters of the program for their state.
