Digitization of GIS data is the process of converting geographical features from real world such as land parcels, railway tracks, schools, hospitals, roads, rivers, and infrastructure etc. into vector format layers that can be viewed, analyzed and shared using Geographic Information Systems (GIS) in standard well known vector formats. Famous geodata formats are GeoJSON, KML and ESRI’s Shapefile etc. GPX format is also used for points and tracks visualization retrieved from GPS devices. By drawing points, lines, and polygons directly on satellite imagery or street maps ( In this application we are using Open Street Maps), users can accurately capture spatial data for mapping, planning, spatial analysis and decision-making.

GIS digitization process is essential for creating and maintaining up-to-date geospatial datasets, especially in fields like urban planning, Disaster management, environmental management, agriculture, utilities like electric utilities, Gas Pipelines, Telecommunication and land surveying. This process helps to convert raster basemap features into meaningful data, enabling students, professionals and researchers to visualize changes over time.
