Map of California topography and geomorphic provinces California's major mountain ranges. California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km 2), California is among the most geographically diverse states.
A supervised classification is a system of classification in which the user builds a series of randomly generated training datasets or spectral signatures representing different land-use and land-cover (LULC) classes and applies these datasets in machine learning models to predict and spatially classify LULC patterns and evaluate classification accuracies.
Township (Twp, T): A square parcel of land of 36 square miles, or a measure of the distance north or south from a referenced baseline, in units of six miles. Witness: Any marker set on the ground that marks or represents some other nearby object or location of surveying importance, such as a corner. For example, a bearing tree is a witness to a ...
One of the reasons for creating sections of 640 acres (260 ha) was the ease of dividing into halves and quarters while still maintaining a whole number of acres. A section can be halved seven times in this way, down to a 5-acre (2 ha) parcel, or half of a quarter-quarter-quarter section—an easily surveyed 50-square-chain (2 ha) area. This ...
When the term 'grid square' is used, it can refer to a square with a side length of 10 km (6 mi), 1 km, 100 m (328 ft), 10 m or 1 m, depending on the precision of the coordinates provided. (In some cases, squares adjacent to a Grid Zone Junction (GZJ) are clipped, so polygon is a better descriptor of these areas.)
The rod is useful as a unit of length because integer multiples of it can form one acre of square measure (area). The 'perfect acre' [2] is a rectangular area of 43,560 square feet, bounded by sides 660 feet (a furlong) long and 66 feet (a chain) wide (220 yards by 22 yards) or, equivalently, 40 rods by 4 rods. An acre is therefore 160 square ...
Of the water transported, about 5 million acre-feet (6.2 km 3) goes to irrigate 3,000,000 acres (1,200,000 ha) of farmland, 600,000 acre-feet (0.74 km 3) supplies municipal uses, and 800,000 acre-feet (0.99 km 3) is released into rivers and wetlands in order to comply with state and federal ecological standards.
The California State Parks system alone has 270 units and covers 1.3 million acres (5,300 km 2), with over 280 miles (450 km) of coastline, 625 miles (1,006 km) of lake and river frontage, nearly 18,000 campsites, and 3,000 miles (5,000 km) of hiking, biking, and equestrian trails.
