In Geographic Information Systems, input devices are used to capture, convert, and transfer spatial and attribute data into digital form for analysis and mapping. These devices differ based on whether the data is raster, which represents space as a grid of cells, or vector, which represents space using points, lines, and polygons. The choice of input device depends on data source, accuracy requirements, scale, and application, especially in GNSS- and GIS-based workflows. Raster data input devices primarily deal with continuous data such as satellite imagery, aerial photographs, scanned maps, and digital elevation models. One of the most common devices is the scanner, which converts hard copy maps, photographs, or drawings into raster format by dividing them into a matrix of pixels. Flatbed scanners are widely used in GIS labs for digitizing maps, while large-format drum scanners are used for high-resolution scanning of large sheets. The resolution of the scanner, measured in dots per inch, determines the spatial detail of the raster data. Another important
