Define geospatial data.  The data that describes both the LOCATION and CHARACTERISTICS of spatial features (such as roads, land parcels, and vegetation stands on the Earth's surface.) What is GIS?  Geographic Information Systems is a computer system for capturing, storing, querying, analyzing and displaying geospatial data. Define geometries and attributes as the two components of GIS data.  Geometric data describe the locations of spatial features, which may be discrete or ...

California LSIT Exam Questions & Answers 2024/2025 A reference ellipsoid. The heights determined by GPS measurements are originally ellipsoidal. These heights are then generally converted to orthometric heights, also known as elevations, by modeling the differences between the geoid and the reference ellipsoid at the newly observed stations using connections to control points with known orthometric points. - ANSWERSThe heights determined by uncorrected GPS measurements refer first to wh...
