What is Q GIS

  • QGIS - Quantum GIS.
  • It is a free and open-source GIS software.
  • Enables users to create, edit, visualize, analyse, and publish geospatial data.
  • Supports multiple file formats and integrates with various plugins for extended functionality.
  • Widely used in mapping, spatial analysis, and land governance across different industries.

WHAT IS DIGITIZATION

  • The art of transforming the analog information into digital format.
  • In GIS context, digitization refers to converting geographic data either from a hard copy or a scanned image into vector data by tracing feature.
  • Digitization is known as vectorization.
