walled off from the dry wood
Sunday, October 30 2011
There wasn't enough snow on the ground to necessitate shoveling, although temperatures remained low enough to ensure that it would remain around for awhile. I'm having to run the woodstove most of the day, and I'm finding that most of the wood I can reach in the woodshed is still a bit too damp. Mind you, the last wood I put in the woodshed was added back in August. But the last wood added had been in living trees as recently as June, and now forms a wall of still-moist wood keeping me from reaching the drier, year-old Silver Maple in the back. I'll probably have to restack part of the shed at some point.
Today I found PHP polygon library capable of determining whether a point or another polygon overlaps with a given polygon. I tried using this to determine whether the region around my house lay within the ranges of various creatures in my fieldguide database, but the mathematics were too memory-intensive for even a modern dual core PC to handle. The problem was that the range maps for many widespread creatures (such as the Cooper's Hawk) consist of polygons with hundreds of verticies. I could just barely perform a Cooper's Hawk range overlap calculation using just the single point here in Hurley, NY; trying to do it with the local tristate area was impossible. Clearly I was going to need to use a different method.
