Tom McKinnon and Jim Sears in Colorado ... have developed a low-cost, remote control drone that takes multispectral images of farmland.
This technology saves farmers money because it is much less expensive than manned aircraft flights or satellite imagery while providing useful information about the health of their plots. These drones can also be fitted with infrared cameras that map the soil moisture content of the area; affording farmers the opportunity to correct dry conditions before they affect crop production.
You may think this technology sounds expensive, but it is actually very affordable and could be used in our own communities to monitor the health of larger, community sponsored agricultural plots.
From a DIY perspective, a drone similar to the one created by McKinnon and Sears could be made for less than $1,000. This is cutting-edge technology that is affordable on most budgets.
