Coordinate Reference Systems
转换数据与地理坐标ystems (GCS)
Coordinate reference systems provide a framework for defining real-world locations. Data is represented using either a geographic coordinate system (latitude/longitude) or a projected coordinate system (x-y).
- Projected Coordinate Reference Systems
Control transformation from geographic to map coordinates; find area distortion - Universal Transverse Mercator System
Work with the Universal Transverse Mercator (UTM) worldwide coordinate grid - Geographic Coordinate Reference Systems
