Geospatial and Monitoring Technology

It should be kept in mind that remote sensing is applicable to areas on the land surface of the earth and areas on and below the surface of the oceans. But it is not applicable to areas under the land surface of the earth. It is applicable for ‘ground water prospect mapping’ but not for ‘underground water mapping’.

Multi-spectral imaging means simultaneous imaging of the earth's surface in more than one wavelength, both visible and invisible, to bring out a lot of latent information which is not available in ordinary photographs. Multi-spectral cameras used in remote sensing usually take four to six photographs at the same time of the same area using different filters. The use of filters helps in identification of different rocks, soils, vegetations, water and other features of the earth's surface, which is not possible otherwise.

Remote sensing, weather forecasting and transmission of signals are the uses of artificial satellites.

  INSAT – 4 is not used as remote sensing satellite.

Correct, they are suitable as they consist of sensor nodes, which have built in intelligence to sense changing conditions.

There are various techniques which may be used in environment scanning namely SWOT Analysis, PEST/ PESTLE Analysis and Industry Analysis. The GE matrix is a model used to assess the strength of a strategic business unit of a corporation.

GALILEO and GLONASS are GPS-like satellite navigation systems of European Union and Russia, respectively. SARAL (Satellite with Argos and Altika project is a collaboration between France and India in the environment monitoring domain with the objective to promote the study of the environment from space) and BHUVAN (a satellite mapping tool similar to Google Earth and Wikimapia; developed by the Indian Space Research Organisation and offers resolution up to 5.8 meters for the Indian Region) are not navigation systems.

Global Positioning System (GPS) is a satellite-based navigation system that determines precise location coordinates (latitude and longitude) based on radio signals from satellites. It's widely used in agriculture for precision farming, mapping, and navigation.

RADAR (RAdio Detection And Ranging) systems use microwave frequencies, typically in the 1-100 GHz range. Microwaves have wavelengths suitable for detecting aircraft and weather patterns - long enough to penetrate clouds and precipitation, but short enough to provide good resolution. Infrared, gamma rays, and X-rays are not used in standard radar systems.

TCAS (Traffic Alert and Collision Avoidance System) is specifically designed to prevent mid-air collisions by interrogating transponders of nearby aircraft and providing vertical guidance to avoid conflicts. AWR is airborne weather radar, GPS is for navigation, and HSI is a cockpit display combining navigation information. TCAS is the only collision avoidance system listed.

Environment scanning is careful monitoring of an organisation’s internal and external environments for detecting early signs of opportunities and threats that may influence its current and future plans. There are three methods which may be used in environment scanning: SWOT Analysis PEST/PESTEL Analysis Industry Analysis

GE Model is not used for environment scanning.

AWR (Aerodrome Weather Report) is a meteorological report that detects and reports weather conditions including storms at an aerodrome. Storms are a critical weather hazard that AWRs are designed to identify for flight safety.

It is used as if the obstructive condition did not exist.

Yes, it is the correct answer.
