- 2. 2 Objectives The aim is to introduce you to the ways in which remote sensing system are used to acquire data, how these data may be analyzed and how the information is used in studies of the natural and human environments.
- 3. Outline • Introduction to Remote Sensing (R.S). • ER Mapper Program • The process of opening an Image in ER Mapper Program • DN Value (Digital Number Value) • Coordinates Value and Distance Measurement
- 4. Remote Sensing Remote Sensing is a since of obtaining information about the properties of an object without coming into physical contact with it.
- 5. Remote sensing process: 1.Energy source (A) 2.Radiation and atmosphere (B) 3.Interaction with the target (C) 4.Recording by the sensor ( D) 5.Transmission ,Reception and processing ( E ) 6.Interpretation and analysis ( F) 7.Application ( G)
- 6. Types of Sensors a. Passive Remote sensing b. Active Remote sensing
- 7. ER Mapper ER mapper is a powerful ,yet simple to use geospatial imagery processing application but this solution enhances your geographic data to make it more meaningful and allow you to extract quantitative information and solve problems. It is ideal for R.S users and other geospatial professionals . ER Mapper has 2 main functions 1- Showing the Satellite Images 2- Processing Digital Satellite Images
