Local Weather Report

Check out the Local Accuweather Weather in the weather widget and you will notice that aerial survey is near impossible here in the southwest.  One of the things to consider when planning a mapping mission is how much visibility is required to complete a mission properly.  Not only is the visibility less than three miles, the cloud base in most of the southwest is about 2000 feet above the ground.  To complicate matters, if ground visibility is important at the time of the mission (and it usually is), then the ground is almost all white today due to continued snowfall.  That makes finding those white ground control points slightly difficult, and aerial photography nearly impossible.
