FALSE COLOUR COMPOSITE (FCC)

-

False Color Composite (FCC):

A False Color Composite is a type of image display technique used in remote sensing and satellite imagery interpretation. It involves assigning different bands of the electromagnetic spectrum to the red, green, and blue color channels of an image to create a false-color representation. In an FCC, colors are not assigned according to their actual visible appearance but based on the specific spectral information contained in each band. 

Landsat 8 is equipped with a multispectral sensor called the Operational Land Imager (OLI), which captures data in several different spectral bands. These bands include visible, near-infrared, and shortwave infrared wavelengths. By creating a False Color Composite using Landsat 8 data, users can visualize various features and characteristics of the Earth's surface more effectively than traditional true-color images.

  • Red Channel (R): Usually assigned to the Near-Infrared (NIR) band (Band 5 or 6). Vegetation appears in shades of red, as healthy vegetation strongly reflects NIR.
  • Green Channel (G): Typically assigned to the Red band (Band 4). Healthy vegetation appears in shades of green.
  • Blue Channel (B): Often assigned to the Green band (Band 3) or Blue band (Band 2). Water bodies and urban areas may appear in shades of blue.
By creating an FCC in this manner, you can enhance the visibility of features such as vegetation health, land cover changes, and water bodies. It's a valuable tool for various applications, including agriculture, forestry, environmental monitoring, and urban planning.

The map shows the FCC of shrirampur tehsil of Hoogly district. It is done with ArcGIS 10.5.

NDWI (Normalized Difference Water Index) USING ARCGIS

Image
The Normalized Difference Water Index (NDWI) is a spectral index used in remote sensing and geographic information systems (GIS) to identify and analyze the presence of water in satellite or aerial imagery. NDWI is particularly valuable for various applications, including environmental monitoring, land cover classification, and water resource management.  Here's a brief overview of NDWI: NDWI can be calculated using Sentinel-2 data by utilizing the bands available in its multispectral sensors. Specifically, NDWI is typically computed using the following bands:   NIR (Near-Infrared): Sentinel-2 band 8 (approximately 842-872 nm) Green : Sentinel-2 band 3 (approximately 534-564 nm) Key Characteristics: Water Detection: NDWI is effective in identifying the presence of water because water absorbs and scatters light differently than other surfaces. As a result, NDWI values tend to be higher in areas with water bodies. Scale Independence: NDWI can be applied at different spatial re...

Topographic Wetness Index

Image
The Topographic Wetness Index (TWI) is a terrain-based algorithm used in hydrology and environmental modeling to quantify the degree of wetness or soil moisture content in a landscape. It calculates the propensity of an area to accumulate water based on terrain characteristics derived from digital elevation models (DEMs).  Here's a brief explanation of the TWI: Calculation Method: TWI is derived from the ratio of local upslope contributing area to the tangent of the slope angle. The formula for TWI often involves the following steps: Slope Calculation: Calculating the slope or gradient of the terrain using elevation data. Steeper slopes generally have lower TWI values. Flow Accumulation: Determining the upslope contributing area, which represents the accumulated flow or water that moves downslope towards a specific location. TWI Formula: The TWI calculation involves dividing the natural logarithm (ln) of the upslope contributing area by the slope. The resulting value represents...
