Georeferencing of Maps

Georeferencing is the crucial process of assigning real-world geographic coordinates to scanned maps and images, transforming them from static representations into dynamic spatial data. By identifying corresponding points on the map and in a GIS, users can mathematically align the image to a specific coordinate system. A critical step following georeferencing is incorporating attributes such as plot numbers and village names to enrich the dataset. This enhances the map's utility by providing detailed information about land parcels, enabling accurate land administration, property management, and resource planning.

OBJECTIVES

1. Efficient Land Management : Facilitating the maintenance of accurate land records, enabling precise property assessments, and supporting effective land use planning.

2. Data Integration : Combining cadastral data with other spatial datasets (e.g., topography, infrastructure, and environmental data) for comprehensive analysis and visualization.

3. Accurate Positioning :Aligning cadastral maps with real-world geographic coordinates to ensure that land parcels, boundaries, and features are accurately positioned on the Earth's surface.
