Answer:
1. Providing a base map for graphical reference and assisting planners and engineers
Satellite Imagery, Remote sensing, GIS, satellite remote sensingThe amount of details that an orthoimagery produces using high resolution satellite imagery is of immense value as it provides a detail image of the selected area along with its surrounding areas.
As maps are location-based they are specifically designed to communicate highly structured data and to give a complete picture about the whole world.There are numerous applications of satellite imagery and remote sensing data. Today nations use information derived from the satellite imagery for government decision making, civil defense operations, police and Geographic Information Systems (GIS) in general.These days, data captured through Satellite Imagery has become mandatory and all government plans are to be submitted on the basis of Satellite Imagery data.
2. Extracting mineral deposits with remote sensing based spectral analysis
Satellite Imagery, Remote sensing, GIS, satellite remote sensingDuring the pre-feasibility and feasibility stages of the mineral exploration, it is important to know about the mineral potentiality of the area to be considered for mineral extraction. In such scenarios, satellite remote sensing based mapping and its integration in a GIS platform help geo scientist to map the mineral potential zones easily by saving time. With the help of spectral analysis of satellite image bands the scientist can quickly identify and map mineral availability through special indicators. This will enable exploration geologist to narrow his geo physical, geo chemical and test drilling activities to high potential zones.
3. Disaster mitigation planning and recovery
Satellite Imagery, Remote sensing, GIS, satellite remote sensingThe result of a natural calamity can be devastating and at times difficult to assess. But disaster risk assessment is necessary for rescue workers.This information has to be prepared and executed quickly and with accuracy. Object-based image classification using change detection (pre- and post-event) is a quick way to acquire damage assessments data. Other similar applications using satellite imagery in disaster assessments include measuring shadows from buildings and digital surface models.
