What does the process of data digitization in GIS involve?

The process of data digitization in GIS specifically involves converting physical maps or images into digital formats. This is a crucial step in making geographic data accessible and usable in a digital environment. During digitization, information from sources such as paper maps, aerial photographs, or scanned images is transformed into a vector or raster format that can be manipulated, analyzed, and displayed using GIS software.

This process not only allows for the preservation of historical maps and valuable spatial information but also facilitates the integration of various types of data for enhanced analysis and visualization. By converting these physical media into digital formats, users gain the ability to perform complex spatial analyses, produce detailed maps, and share their findings more easily.

While the other choices may involve data management and usage within GIS, they do not specifically refer to the digitization process. Creating new datasets, analyzing spatial relationships, and updating existing data sets relate to different aspects of GIS workflows following the digitization stage.
