🗺️ What is Cartography?
Cartography is the art and science of making maps. It involves collecting, analyzing, and presenting geographic data visually. A well-designed map can communicate complex spatial information in a simple, effective way.
🔍 Key Aspects of Cartography:
Data Collection: From field surveys, satellite data, GPS, etc.
Map Design: Use of symbols, legends, colors, and scales to enhance readability.
Projection and Scale: Representing 3D earth on a 2D surface.
📖 Example: A topographic map of Pokhara shows contour lines that help engineers plan road alignment and drainage.
🌐 What is Remote Sensing?
Remote Sensing (RS) is the process of obtaining information about the Earth's surface without making physical contact. It uses sensors mounted on satellites, drones, or aircraft to capture images and data.
🔍 Key Components of Remote Sensing:
Sensor: Device that detects radiation (e.g., Landsat, Sentinel).
Platform: The carrier of the sensor (e.g., satellite, UAV).
Data Processing: Converting raw data into usable images and maps.
Applications: Land cover mapping, flood monitoring, urban growth analysis.
📖 Example: Remote sensing is used to monitor forest loss in the Chitwan National Park using satellite images.
🔁 Difference Between Cartography and Remote Sensing
| Basis | Cartography | Remote Sensing |
|---|---|---|
| Purpose | Map creation | Data acquisition |
| Source of Data | Field survey, remote sensing | Sensors (satellites, drones) |
| Output | Maps, atlases | Images, spectral data |
| Tools Used | GIS software, drawing tools | Satellites, sensors, image processing tools |
🛰️ Applications in Nepal
Cartography: Preparation of topographic maps by the Department of Survey.
Remote Sensing: Mapping of landslide-prone areas in hilly regions using satellite data.
Combined Use: In hydropower project planning, both cartography and RS help analyze terrain and land use.
