Filtering in Remote Sensing. Convolution. Edge enhancement. Low pass filter and High-pass filter Spatial filtering is a technique used in remote sensing to enhance the spatial resolution of an image. This is typically done by using a mathematical algorithm to process the raw data collected by the remote sensing instrument, with the goal of reducing noise and improving the overall quality of the image. Spatial frequency in remote sensing refers to the density of spatial details or features in an image. It is a measure of how quickly the intensity or brightness of an image changes over a given distance. High spatial frequency indicates a high density of fine details or edges in an image, while low spatial frequency indicates a low density of fine details or edges. Spatial frequency is an important concept in remote sensing because it can affect the ability to detect and interpret features in an image. It can also be used to evaluate the quality and usefulness of an image for certain type...

ദക്ഷിണ ആൻഡമാൻ കടലിൽ 2020 ഏപ്രിൽ 30 നോട് കൂടി ഒരു ന്യൂനമർദം രൂപപ്പെടാൻ സാധ്യതയുണ്ടെന്ന് കേന്ദ്ര കാലാവസ്ഥ നിരീക്ഷണ കേന്ദ്രം അറിയിച്ചു. ശേഷമുള്ള 48 മണിക്കൂറിൽ ന്യൂനമർദം കൂടുതൽ ശക്തി പ്രാപിക്കുകയും ആൻഡമാൻ നിക്കോബാർ ദ്വീപുകൾക്കടുത്ത് കൂടെ മുന്നേറാനുള്ള സാധ്യതയും പ്രവചിക്കപ്പെട്ടിരിക്കുന്നു. ന്യൂനമർദത്തിന്റെ രൂപീകരണവും അതുമായി ബന്ധപ്പെട്ട് ഉണ്ടാകാൻ ഇടയുള്ള മോശം കാലാവസ്ഥയും സൂക്ഷ്മമായി നിരീക്ഷിച്ച് വരികയാണ്. മത്സ്യബന്ധനത്തിനായി കടലിൽ പോകുന്ന മത്സ്യതൊഴിലാളികൾ കാലാവസ്ഥ വകുപ്പിന്റെയും ദുരന്ത നിവാരണ അതോറിറ്റിയുടെയും മുന്നറിയിപ്പുകൾ കർശനമായി പാലിക്കേണ്ടതാണ്. Formation of Low Pressure Area over south Andaman Sea and neighbourhood around 30th April 2020. As per the forecast guidance from various numerical weather prediction models and the environmental and thermo-dynamical conditions prevailing over the region, a Low Pressure Area is very likely to form over south Andaman Sea and neighbourhood around 30th April 2020. It is very likely to intensify further during subsequent 48 hours. It is very likel...
