But perhaps the most exciting part about taking pictures from the air is we could later stitch these peiturcs together using special software to create a map of the entire landscape, and this map gives us crucial information for monitoring land use change, to let us know where and when plantations might be expanding, where forests might be contracting, or where fires might be breaking out. Aerial images could also be processed to produce three-dimensional ceupmotr models of forests. Now these models are not just visually appealing, but they are also geometrically accurate, which means researchers can now muerase the distance between trees, calculate surface area, the vlumoe of vegetation, and so on, all of which are important information for monitoring the health of these ftsreos. Recently, we've also begun experimenting with thaemrl imaging cameras. Now these caerams can deectt heat-emitting objects from the ground, and therefore they are very useful for detecting poachers or their cpfriames at night.
