    • Har Khet Ko Pani – Ensuring irrigation for every farm.
    • Per Drop More Crop – Promoting micro-irrigation (drip & sprinkler irrigation) to improve water-use efficiency.
    • Watershed Development – Improving soil moisture retention and groundwater recharge.
  • Encourages participatory irrigation management through Water User Associations (WUAs).

6. Jal Jeevan Mission (JJM)

  • Launched in 2019 to provide tap water connections (Functional Household Tap Connection - FHTC) to all rural households by 2024.
  • Focuses on source sustainability, groundwater recharge, and greywater management.
  • Encourages community participation, local governance, and water budgeting.
  • Uses sensor-based real-time monitoring for efficient water supply tracking.

7. Atal Bhujal Yojana (ABHY)

  • A groundwater management program launched in 2020 with World Bank assistance.
  • Targets groundwater-stressed areas in seven states: Gujarat, Haryana, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan, and Uttar Pradesh.
  • Focuses on community-driven, demand-side water management.
  • Encourages cropping pattern changes, rainwater harvesting, and groundwater recharge.
  • Strengthens data collection and monitoring of groundwater levels.

8. Catch the Rain Campaign

  • Launched under the National Water Mission (NWM) in 2021.
  • Promotes rainwater harvesting and conservation before the monsoon season.
  • Focus areas:
    • Repairing traditional water bodies (lakes, ponds, stepwells).
    • Creating new water conservation structures.
    • Encouraging rooftop rainwater harvesting.
    • Engaging local authorities and communities in water conservation activities.

9. River Basin Management Initiatives

  • Focuses on integrated river basin planning and interlinking of rivers.
  • Interlinking of Rivers (ILR) Project:
    • Aims to transfer surplus water from water-abundant regions to drought-prone areas.
    • Proposed 30 inter-basin water transfer links (14 Himalayan & 16 Peninsular).
    • Major projects include Ken-Betwa River Linking, which benefits Madhya Pradesh and Uttar Pradesh.
  • Promotes scientific river basin modeling and flood management.

10. National Hydrology Project (NHP)

  • Strengthens water resource management through hydrological data and advanced technology.
  • Uses satellite-based monitoring, remote sensing, and GIS tools.
  • Develops a real-time hydrological database for better decision-making.
  • Supports flood forecasting, groundwater assessment, and drought management.

Radar Remote Sensing SAR

1. Radar and Radar Remote Sensing RADAR stands for Radio Detection and Ranging . It is an active remote sensing system that transmits microwave energy toward the Earth's surface and records the energy that is returned to the sensor as an echo or backscatter . Unlike passive optical remote sensing, radar does not depend on sunlight. Therefore, it can operate day and night and, at suitable wavelengths, can acquire data through clouds, haze and light rain. Hence, radar is widely described as an all-weather, day-and-night remote sensing technology . Basic principle Microwave pulse → transmission → interaction with surface → backscatter/echo → antenna receives signal → signal processing → radar image 2. Microwave Energy Radar systems use microwave electromagnetic radiation , generally in wavelength ranges from approximately 1 mm to 1 m . Important radar bands include: Band Approx. wavelength Common applications ...

Lidar

LiDAR (Light Detection and Ranging) is an active remote sensing technology that measures distances by illuminating a target with laser pulses and analyzing the time it takes for the reflected light to return. Unlike passive systems (e.g., cameras, multispectral sensors), LiDAR provides its own energy source (laser), allowing it to operate both day and night and even penetrate through vegetation canopies . 🔹 How LiDAR Works (Step-by-Step Process) Laser Pulse Emission The system emits rapid, short pulses of laser light (commonly in the near-infrared wavelength, 1064 nm ). Some systems emit up to hundreds of thousands of pulses per second . Interaction with Target Surface The laser beam strikes objects such as vegetation, buildings, or bare ground. Depending on the object's structure, part of the pulse may scatter or reflect. Return Signal Detection The sensor records multiple returns : First Return → typically vegetation canopy tops. ...

Geometric Correction

When satellite or aerial images are captured, they often contain distortions (errors in shape, scale, or position) caused by many factors — like Earth's curvature, satellite motion, terrain height (relief), or the Earth's rotation . These distortions make the image not properly aligned with real-world coordinates (latitude and longitude). 👉 Geometric correction is the process of removing these distortions so that every pixel in the image correctly represents its location on the Earth's surface. After geometric correction, the image becomes geographically referenced and can be used with maps and GIS data. Types  1. Systematic Correction Systematic errors are predictable and can be modeled mathematically. They occur due to the geometry and movement of the satellite sensor or the Earth. Common systematic distortions: Scan skew – due to the motion of the sensor as it scans the Earth. Mirror velocity variation – scanning mirror moves at a va...

Image Transformation

In remote sensing, image transformation is used to create new images by manipulating existing ones, enhancing the information extracted from each pixel. Multi-image manipulation and other transformations allow analysts to highlight specific features, compare time-series data, or reduce data dimensions for better interpretation. 1. Multi-Image Manipulation This technique involves applying mathematical operations to multiple images, typically from different bands, dates, or sensors, to highlight specific features or changes. Common methods include: a. Image Addition Purpose : Highlights areas of similarity or enhances features when the same objects appear in multiple images. How it Works : By adding pixel values from two images, the output image emphasizes areas where brightness is high in both. Example : Enhancing overall brightness or detecting seasonal changes by adding images from different times. b. Image Subtraction Purpose : Identifies differences between images, useful for chan...

Spatial Feature Manipulation and Filtering

1. Spatial Feature Manipulation: Spatial Frequency Spatial frequency describes how quickly brightness changes across an image. It can reveal different levels of detail, based on how often these changes occur: High Spatial Frequency : Areas where brightness changes quickly, like edges, fine textures, or detailed patterns. These parts contain high detail but can also include noise. Low Spatial Frequency : Areas with gradual changes in brightness, like smooth surfaces or broad homogeneous areas. These regions are usually featureless, such as water bodies or large agricultural fields. Zero Spatial Frequency : Represents a completely uniform area with no brightness variation. This area is very smooth and has no texture or detail. By manipulating spatial frequencies, we can enhance or suppress certain features in an image. Spatial filtering is one of the primary methods to perform this manipulation. 2. Spatial Filtering and Spatial Domain Spatial filtering is the process of applying mathe...
