What is the Wavelength of Light? Why Can Satellites See Things which are Invisible to the Human Eye?
Having knowledge of wavelengths is essential for analyzing satellite data. What can be examined at different wavelengths? Let's compare the differences in satellite images based on wavelengths.
Basics of Geographic Information Systems (GIS) – Capabilities, Applications, GIS Data, Software-
We have compiled the basic essentials needed when using GIS (Geographic Information Systems), including what it can do, application examples, and software.
Summary of Government Support Programs and Budget Allocations for the Space Industry in Japan: Space Strategic Fund, SBIR, Stardust Program, and K Program
We have summarized the objectives and overall picture of the space technology development support that the Japanese government is actively promoting, the status of support by category, and points to watch going forward.
Japanese space startups discuss how satellite data usage can be accelerated
Satellite data in the earth observation field rapidly expands and influences diverse industries, but challenges remain for further diffusion. Three companies (Synspective,SPACE SHIFT,Warpspace) spoke to us about their businesses and the challenges and prospects for satellite data utilization.
The 4th Tellus Satellite Challenge! Explanation of approaches taken by the winners
"Coastline extraction" was the theme of the 4th Tellus Satellite Challenge. In this article, we will look at the approaches taken by the winners, make comparisons, and summarize their methods so that they can be applied to other (satellite) image data competitions.
Is the Susanoo Shrine built in a location that is resistant to flood damage? We took a look at the enshrined deity and used satellite data to examine the city it is in.
In this article, we will be using the satellite data platform "Tellus" to look into a series of shrines called the Yasaka Shrines, which have both Buddhist and Shinto aspects to them. We will look specifically at their Hikawa sect which enshrines the deity Susanoo. Looking at Shrines From Space! Pretty Cool, Eh?
Space as a “means” used in business: summary of market size and operators of microsatellites
Compared to large satellites, small satellites can be developed at a lower cost and in less time. An increasing number of companies are developing small satellites, especially microsatellites. This article explains what companies are working on, in what fields, and also how to make a small satellite.
Using Amedas Data to Visualize Temperature Forecasts and Rainfall in Real Time.
For this article, we used the Amedas minute-by-minute data available on Tellus for our analysis. We looked specifically at the minute-by-minute Amedas data in northern Kyushu for rainfall that occurred between 5th and 6th of July 2017.
Using SSD to Perform Object Detection on Airplanes
For readers who want to try using machine learning and satellite data to do something interesting, we'd like to suggest trying out object detection. In this article, we attempt to use satellite data in order to perform object detection on airplanes.
Do Smaller Antenna Really Correlate With Higher Resolution? Thorough Examination of One of SAR’s Mysteries Without Using any Formulas!
This time, we are speaking with a broad group of people who are interested in SAR images, including an engineer who processes them, to a business developer, obsessed with the SAR industry, to learn what determines the resolution of SAR images from top to bottom.
Imaging PALSAR-2 L1.1 using Tellus [with code]
This article describes how to extract and visualize complex images (images with phase and reflection intensity information of radio waves) from PALSAR-2 L1.1 data released on Tellus in accordance with the format called the CEOS format.
