Definition of Vector Data in GIS

Vector data in GIS represents geographic features using points, lines, and polygons to illustrate locations and shapes.

Key Features:

• Points: Used for specific locations (e.g., wells, trees).
• Lines: Represent linear features (e.g., roads, rivers).
• Polygons: Show area features (e.g., lakes, parks).

Overview

Vector data is crucial for detailed mapping and analysis in Geographic Information Systems (GIS).

What is Remote Sensing?

Remote sensing is the technology used to gather information about the Earth from a distance, usually using satellites or aircraft.

Key Features:

• Data Collection: Captures images and measurements.
• Applications: Used in agriculture, forestry, and environmental monitoring.
• Tools: Includes satellites, drones, and aerial photography.

Overview

Remote sensing helps us understand and manage natural resources and monitor changes in the environment efficiently.
