Where remote sensing differs from photogrammetry is in the type of This paper presents an overview of remote sensing, its types and applications. Pressures on water resources and disaster management are rising primarily due to the unequal spatial and temporal distribution of water resources and pollution, and also partially due to our poor knowledge about the distribution of water resources and poor management of their usage. It focuses on remote sensing studies that address specific topics with an emphasis on environmental and societal issues - regional / … Spatial (what area and how detailed) 2. Remote sensing is used in numerous fields, foundations for future research established and can be including geography, land surveying and most Earth efficiently used in Agriculture for better results. You can easily assess the effects of global warming and alarming symptoms of the rise of the water sea level and its … As the authoritative record of changing conditions on the ground, remote sensing imagery has a broad array of applications in traditional terrestrial human activities that involve the management of land. Space Application Centre is continuously monitoring glaciers in order to observe climate change impacts. 1 Star - I hated it 2 Stars - I didn't like it 3 Stars - It was OK 4 Stars - I liked it 5 Stars - I loved it. In this remote sensing application, satellite imagery is used without even requiring to physically measuring the tank.

Sunlight reflection is the most common source of radiation measured by passive sensors. But it is in the field of agriculture that remote sensing has found significant use. The applications of remote sensing include geology and mineral exploration, oceanography, agriculture, forestry, land degradation, environmental monitoring and so on. The International Society of Photogram-metry and Remote Sensing (ISPRS) is a non-governmental organization devoted to the advancement of photogrammetry and remote sensing and their applications. Remote means – far away ; Sensing means – believing or observing or acquiring some information. Box 9718, Beijing 100101, China, tqx@hrs.irsa.ac.cn ABSTRACT In recent years, hyperspectral remote sensing has stepped into a new stage in China. Remote Sensing data is one of the primary data sources in GIS analysis. After reading this article you will learn about:- 1. 1 Agriculture 1 Sesha Sai MVR, Ramana KV & Hebbar R 2 Land use and Land cover Analysis 21 Sudhakar S & Kameshwara Rao SVC 3 Forest and Vegetation 49 Murthy MSR & Jha CS 4 Soils and Land Degradation 81 Ravishankar T & Sreenivas K 5 Urban and Regional Planning 109 Space Application Centre is continuously monitoring glaciers in order to observe climate change impacts. Remote sensing provides a cheap alternative for data acquisition over large geographical areas (De beurs and Townsend, 2008). Fig.1: Stages of Remote Sensing. (2) Interpretative: It involves recognition of objects and judging their significance through careful and systematic analysis.
