Methane is a greenhouse gas. It adds to global warming. Plumes of methane emissions are detectable through satellite-based sensors.
Ever wanted to compare areas in terms of greenery? Remote sensing data may present you with some answers. Here, we present a use case that can help us understand the utility of such information.
Whether urban afforestation truly has an impact? By investing in urban afforestation, how much is it helping their city? Is there a way for them to maximize the cooling effects they achieve?
Nitrogen dioxide concentrations in the NCR appear to be declining, according to a Sentinel-5 based change analysis between 2019 and 2023.
At the location of Lord Rama's birth, Ayodhya in the Indian state of Uttar Pradesh has recently seen an unprecedentedly large-scale construction project. We conducted a comparative visual analysis using Sentinel-2 satellite images from January 2020 and 2024. The analysis unequivocally shows that the area around the temple site has undergone significant change.
Soil organic carbon (SOC) might be invisible to the naked eye, but it’s one of the major parameters driving soil health and fertility. Measuring and predicting its levels across landscapes, especially in vulnerable semi-arid regions, is critical for sustainable land management. This blog delves into the arena of SOC mapping, […]
The early part of the twenty-first century has recorded the forest carbon loss increasing in the tropical regions. A remote sensing study to this effect was conducted that extensively used the vast collection of Landsat satellite images. Forest cover change Landsat 30 m spatial resolution data was aggregated yearly to […]
Kolleru Lake is India’s largest freshwater lake. In recent years, satellite images of the lake witnessed the fishpond lakes developing, drastically altering the region’s land use and land cover. The analysis employed Landsat images over the year 2018. A median image was generated using all the cloud-free images available during […]
As derived from Landsat series datasets, the satellite-based land surface temperature data is prevalent among researchers studying surface urban heat islands. Surface urban heat island is the term given to the land surface temperature difference in urban areas concerning the land surface temperature of the surrounding surface. The following are […]
