InSAR, also known as Interferometric Synthetic Aperture Radar, is a highly effective tool for remotely tracking changes in the Earth's surface using satellite-based radar. However, its accuracy can be affected by thick vegetation or snow cover. To address this issue, specialized InSAR satellites with L-band technology utilize longer wavelengths that can penetrate through vegetation, but their measurements may not be as precise as those taken by InSAR satellites with shorter wavelengths. In areas with heavy snow, InSAR monitoring is typically halted during the winter season, but data collected before and after this period can be used to fill in the gap. In our blog post, “How vegetation and snow impact InSAR readings”, we examine some of the considerations when using InSAR to monitor difficult terrain.

Iran has launched two new domestically-made satellites into orbit in cooperation with Russia, using a Soyuz launch vehicle. The Iranian satellites, called Kowsar and Hudhud, were launched into the 500-kilometer orbit of the Earth. These were the first Iranian satellites launched on behalf of the country’s private sector. Weighing 30kg, Kowsar has an estimated orbital lifespan of over three years and can transmit color imaging with a range of 15km and at the rate of 6 frames per second. The satellite images are suitable for use in agriculture, land surveying, and cadaster. Hodhod weighs 4kg and has an orbital height of 500 km with about four years of lifespan. The data from this satellite is also useful for agriculture, mapping, transport, and the environment.

It’s great to see even more validation of FABDEM’s quality being produced by the academic community. In a recent paper published in the International Journal of Digital Earth, researchers Michael Meadows, Simon Jones and Karin Reinke set out to assess the vertical accuracy of five different open access global digital elevation models (DEMs). When assessed against Copernicus DEM, NASADEM, AW3D30 and SRTM, Fathom and the University of Bristol’s FABDEM came in first place. Read the full paper here: https://lnkd.in/exfXCqtq FABDEM is the base on which we built our Global Terrain Data - FABDEM+, blending globally consistent elevation data with high-quality LiDAR data to create the new standard for a globally consistent and accurate digital elevation model.

When working on geospatial projects, choosing the right satellite imagery can make all the difference. Landsat, Sentinel, and MODIS are three of the most widely used Earth observation programs, each offering unique strengths for applications like agriculture, climate monitoring, and land use mapping. This infographic highlights their differences in spatial resolution, temporal resolution, spectral capabilities, and more to help you select the best tool for your needs. Please Note: The images are for aesthetics & illustrative purposes only — they are not the exact images for Landsat, Sentinel & MODIS.

Satellite imagery is an important aspect of spatial decision-making. It allows decision-makers to understand the problems without the need to be there physically. That is remote sensing. In this video, you will learn how to download Landsat 8 imagery from USGS in just a few minutes. #gis #remotesensing #mapping #landsat #satelliteimagery #arcgis https://lnkd.in/dpMrYq-R
