Physical geography is the spatial study of our home planet and all of its components: its lands, waters, atmosphere, and interior. Like other sciences, physical geography is a science that is grounded in scientific knowledge using the scientific method as the fundamental way to understand the environment.Geographers and all spatial scientists require a strong background in understanding in the way humans have partitioned the earth to determine location. In order to do that, a series of lines representing angular measurements on the earth were established, known as the geographic grid system. Once that has been done, spatial knowledge can be collected and analyzed based on geographic or spatial data. This allows us to understand spatial concepts of patterns, distributions, and flows based on location and spatial boundaries.Often times this geographic data must be collected and analyzed using a high-tech and dynamic technology called geospatial technology. This technology encompasses powerful remote sensing technology, global positioning systems, and geographic information systems.
