GULU UNIVERSITY. FACULTY OF AGRICULTRE BIOSYTEM ENGINEERING ABE 2112: GIS and Remote sensing OMONG GILBERT ALLAN 2201001906 22/U/1906/GSB/PS 1**.Is GIS dynamic systems or static systems? Explain your answer** GIS can be both dynamic and static, depending on how the system is used, the data involved, and the objectives of the application that is Static system is suitable for applications where the data does not change frequently, such as historical studies or long-term planning. Dynamic system is essential for applications requiring real-time monitoring, such as weather forecasting, traffic control, or emergency response. 2**.Give five examples of the following data type we can find in Gulu university** a\. Spatial data - Sports Field - Agricultural Research Field - Campus Health Center - Parking Area b\. Non spatial data - Academic Records like examination results. - Course Information like course titles. - Staff Information like Names of lecturers and staff: and Staff ID numbers. 3**.Discuss the relationship between the components of the GIS, stating the role of eachcomponent** - Hardware, provides the physical infrastructure required to run GIS software, store large datasets, and process complex spatial analyses. The software depends on the hardware for running applications, processing data, and generating maps - Software, Provides the tools and functionalities for performing GIS tasks such as data management, analysis, and map production. Software transforms raw spatial and non-spatial data into meaningful information. - Data, Forms the foundation of GIS, consisting of both spatial data and non-spatial data. Software processes, analyzes, and visualizes the data, transforming raw inputs into actionable insights. - User, who design, implement, and maintain the GIS systems. They use the software and hardware, manipulate data, and apply methodologies to achieve specific objectives. 4.**What are the advantages of using vector data over raster and vice versa?** Advantages of Vector Data over Raster Data - Vector data is highly precise because it represents features as points, lines, and polygons. - Vector data can be scaled without losing quality. - Vector data generally consumes less storage space compared to raster data, especially when representing large areas with minimal variation. - Vector data is well-suited for representing discrete features (e.g., roads, boundaries, buildings. Advantages of Raster Data over Vector Data. - Raster data excels in representing continuous phenomena like temperature, elevation, precipitation. - Raster data is easier to work with for mathematical operations, such as overlays or combining multiple datasets. - Raster data is naturally suited for images, such as remotely sensed data.
