System for monitoring the depth of snow
First Claim
1. A system for monitoring the depth of snow with respect to the ground, said system comprising:
- initialization means for generating ground surface data representative of the surface of a section of ground;
acquisition means for generating snow surface data representative of the surface of the snow on said section of ground; and
analysis means in communication with said ground surface data and said snow surface data for comparing said ground and snow surface data, and for generating data representative of the snow depth between said ground and snow surfaces.

Abstract
A system is disclosed for monitoring the depth of snow with respect to the ground. The system may employ a global positioning system and includes an initialization unit for generating ground surface data representative of the surface of the ground. The system also includes a snow surface data acquisition unit for generating snow surface data representative of the surface of the snow. The system further includes an analysis unit in communication with the ground surface data and the snow surface data for comparing the ground and snow surface data. Snow depth data is then generated representative of the area between the ground and snow surfaces.
