Study Notes
Geographic Information Systems (GIS)
- GIS stands for Geographic Information Systems, a framework for gathering, managing, and analyzing spatial and geographic data.
Common Data Types in GIS
- GIS commonly uses data types such as vector data (points, lines, polygons) and raster data (grids of pixels representing continuous data).
- A data type that is NOT commonly used in GIS may include non-spatial formats, such as simple text documents.
Remote Sensing vs GIS
- The primary difference between remote sensing and GIS lies in their functions; remote sensing focuses on collecting data about the Earth's surface from a distance (often via satellites), while GIS integrates and analyzes that spatial data to provide insights.
Applications of Remote Sensing
- Common applications for remote sensing include environmental monitoring, agriculture, urban planning, and disaster management.
- An example of a function NOT typically associated with remote sensing might be direct data entry or manual inventory management.
Benefits of GIS for Spatial Analysis
- A key benefit of using GIS for spatial analysis is its ability to visualize complex spatial relationships and patterns, enhancing decision-making and strategic planning.
