With these series of articles, we wish to provide a comprehensive analysis of what, where and how the satellite imagery accessed through our system can be used. In each article starting with this one, we will explore a few satellite imagery bands in detail with their applications.
Applications of Satellite Imagery Bands - Part 1: Coastal Aerosol (B1), Blue (B2), Green (B3), and Red (B4)
With these series of articles, we wish to provide a comprehensive analysis of what, where and how the satellite imagery accessed through our system can be used. In each article starting with this one, we will explore a few satellite imagery bands in detail with their applications.
The Red Edge band is located between the Red band (B4) and the NIR band (B8), without overlap. In a typical spectral response of green vegetation, the Red Edge band covers the portion of the spectrum where reflectance drastically increases from the red towards the NIR regions.
Impact Analysis of Volcano-Induced-Tsunami in Indonesia Using Farmonaut
A tsunami swept across Indonesia’s islands of Sumatra and Java the night of December 22, just before 9:30 p.m. local time. There was no notice for the wall of water, which left devastation in its wake. At least 400 are confirmed to be dead and more than 800 are injured. Because of such a large impact of this event, we wanted to analyze the extent of devastation in the coastal region of the affected areas.
Mapping Volcanic Activity Using Farmonaut
We mapped Mount Veniaminof’s volcanic activity using the short wave infrared satellite imagery accessed through our system. Recently, Mount Veniaminof had been in the news for it’s extreme volcanic activity wherein it ended up spewing ash as high as three miles in the air. The activity was so intense, that the region near it was declared as a no-fly zone.
Analyzing Water Level of Lakes of Udaipur (India) Using Farmonaut
To understand how the condition of lakes change over a course of a year, we shifted our focus to some of the famous lakes in India. Udaipur is known for its beautiful lakes, so we decided to analyze four famous lakes of udaipur, namely: Dudh Talai, Lake Pichola, Swaroop Sagar and, Fateh Sagar Lake.
Time Lapse of Californian Fire
The spread and extent of fire in California is massive and devastating. So, we decide to have a look on the imagery of the last month. The spread and extent of fire in California is massive and devastating. So, we decide to have a look on the imagery of the last month over a region in California and have created a Time Lapse of the same. The imagery is accessed through our On Demand Satellite Imagery System.
Farmonaut provides satellite based crop health monitoring system, through which farmers can select their field and identify the regions of the field at which the crop growth is not normal. Upon identifying that region of their fields, they can simply pay a visit to that part of the field and identify if the problem has already started. If it has not, the farmer can take preventive remedies by applying more fertilizers, plant growth regulators etc.
