|---|---|---|
| 1 | Electromagnetic spectrum, interaction of electromagnetic waves with earth’s surface and atmosphere, image characteristics - scale, brightness and tone, contrast ratio, detectability, recognizability, signature, texture, interpretation key, spatial resolution and resolving power, remote sensing platforms. Remote sensing systems - framing systems, scanning systems and multispectral systems. Aerial photographs: types of aerial photographs, photographic scale, relief displacement, stereoscopic vision, vertical exaggeration, geotechnical elements, photo-mosaics. |
|
| 2 | Active and passive sensors; MSS, LISS, CCD, infra-red and thermal scanners. Low earth orbit and geostationary orbit, Indian remote sensing series, different satellite PROGRAMMEs, microwave sensors, fundamentals of image interpretation and analysis and false color composite. |
|
| 3 | Interpretation and analysis of aerial photographs and images for identification of different rock types, structures, lineaments, recognition of landforms, drainage patterns. Application in engineering projects, (dam, reservoir, tunnel alignment, route location etc.), groundwater prospecting, geothermal studies, geo-environmental studies (soil conservation, land degradation etc.) and disaster management (flood, landslides etc.). Role in resource management. |
|
| 4 | Components of GIS: hardware and software. GIS data types, raster and vector data models. Concept of thematic layers and topology. Triangulated irregular networks (TIN), digital elevation model, digital terrain model and their applications. Global positioning system and its application in Geology. |
