Georeferencing Raster Images
- involves aligning a raster image with a known coordinate system.
- Challenges include finding sufficient and accurate control points, identifying potential distortions, and selecting the appropriate georeferencing method.
Control Points
- Ground control points (GCPs) are used to define the geometric transformation between the raster image and the coordinate system.
- GCPs should be well-distributed and have accurate coordinates.
3. How do you create and maintain a geospatial database, including data modeling, storage, and access?
– Data modeling: Define the structure and relationships of the geospatial data using data models like ER diagrams or object-oriented models. – Storage: Select an appropriate database management system (DBMS) that supports spatial data types and operations, such as PostGIS or Oracle Spatial. – Access: Implement efficient data access mechanisms, such as spatial indexes, to optimize queries and improve performance.
4. Explain the key principles and components of a Geographic Information System (GIS)?
- Data: GIS stores and manages geographic data in various formats, including vector, raster, and tabular data.
- Hardware: GIS requires a computer system with sufficient processing power, memory, and storage capacity to handle large datasets.
- Software: GIS software provides tools for data input, analysis, visualization, and output.
