Data Types Used in GIS for Geological Applications
In the realm of Geographic Information Systems (GIS), understanding the different types of data is crucial. Data types play an essential role in how geological information is analyzed, represented, and utilized. Within this context, two major categories are often discussed: raster and vector data. Each has its own advantages, disadvantages, and specific applications in geological studies.
Raster vs Vector Data
Raster data consists of grid cells or pixels, where each cell contains a value representing information, such as temperature, elevation, or spectral data. This format is particularly useful for continuous data, like satellite imagery or digital elevation models. Raster data is often easier to manipulate for certain types of analyses, especially those involving image processing and surface modeling.
Benefits of Raster Data:
