Horse blanket rear, but usually it has no other straps or attachments. It is intended to be used on a horse while the animal is being led or held by a person, and not left on an unattended horse. In windy weather, a loose surcingle may be added to prevent the cooler from blowing completely off. A traditionally-shaped blanket of loosely crocheted cotton, called an "anti-sweat sheet", is used to absorb moisture. Often used alone to wick moisture from the surface of the horse, if placed under a cooler, it is removed when it becomes wet. A "barrier blanket" is sometimes used
Tree girth measurement was repeated at different heights to create a three-dimensional model of the tree. This mapping process can be automated. Taylor has been developing a cloud mapping process using optical parallax scanning technology whereby thousands of measurements are made around the trunk of a tree. These can be used to recreate a three-dimensional model of the trunk and girth and diameter data are among the values that can be calculated. For long term monitoring of girth, the exact point on the tree needs to be marked to assure the measurement is taken in the same place every session. Forestry data suggests
