🌍 Addressing Geometric Challenges in Satellite Imaging for Land Monitoring 🛰 Satellite images often suffer from geometric errors that impair land monitoring and change detection analysis. These misalignments between consecutive acquisitions introduce noise and inaccuracies, particularly in high-temporal-resolution data collections such as Sentinel-2, Landsat, and PlanetScope. The article, written by Peresutti explores how to co-register a temporal stack of optical satellite images to mitigate these errors. Through extensive experiments, a workflow was developed that uses image-based co-registration to accurately align temporal images, thereby improving analysis accuracy. It was found that using an average temporal image as the template and a translation-only motion model produces the best results, significantly reducing the impact of geometric errors. These findings have been incorporated into the eo-learn library to facilitate use by other researchers and professionals. 🔗 More details and results are available in the blog: https://lnkd.in/dMfuqw3g #SatelliteImagery #GeometricErrors #LandMonitoring #ChangeDetection #MachineLearning #Sentinel2 #RemoteSensing #eoLearn #GIS #DataScience

"Spatial resolution is essentially the level of detail represented by each pixel in an image. It's like the fine print of Earth observation, determining how sharp and clear the image is. Let's embark on a journey through the various spatial resolutions and unravel their importance in different applications." - cloudeo #satellitedata #remotesensing #spatialresolution

https://lnkd.in/gZ2unkDx Check out this video showcasing how DEEP BLOCK extracts land cover from high-resolution aerial orthophotos. We've recently enhanced DEEP BLOCK's image segmentation application by adding a polygon correction feature. This innovative update empowers users to leverage the geolocation data of various objects found in DEEP BLOCK when analyzing ultra-high resolution images, thereby eliminating the need for tedious post-processing tasks. Here’s how it works: DEEP BLOCK's advanced algorithms automatically identify and segment different land cover types, such as forests, urban areas, and water bodies, with remarkable accuracy. With the new polygon correction feature, users can extract these segmented areas with more precise boundaries. This becomes particularly valuable when working with complex landscapes or areas where land cover types frequently change. While tools like ARCGIS and QGIS offer polygon merging and correction functions, DEEP BLOCK has integrated these features seamlessly within its platform. This integration means you won't need to switch between multiple software programs or perform additional steps to achieve the desired level of detail and accuracy. DEEP BLOCK simplifies the process, allowing you to focus on analysis and decision-making. Imagine the time saved and the increased efficiency when mapping large areas for environmental studies, urban planning, or disaster response. DEEP BLOCK’s combination of high-resolution imagery and sophisticated image segmentation ensures that you get reliable, actionable insights without the hassle of manual corrections. But that's not all. DEEP BLOCK’s no-code interface makes it accessible even to those who may not have extensive technical expertise. Whether you're a seasoned GIS professional or a newcomer to remote sensing, DEEP BLOCK provides the tools you need to achieve professional-grade results. Get started with DEEP BLOCK for free today and experience the future of no-code computer vision for remote sensing. Visit deepblock.net to learn more and take your first step towards more efficient and accurate land cover analysis.

Exploring the potential of generating Digital Elevation Model (DEM) utilizing Sentinel-1 SAR SLC images. DEMs are crucial for spatial analysis, offering a three-dimensional view of terrain which is vital for applications ranging from urban planning to environmental management. While freely available DEMs (such as SRTM, EU-DEM, etc.) offer a convenient solution, in cases involving dynamic environments such as mines, the use of an up-to-date DEM is essential so that the study's results correspond to the current landscape. The solution in these cases is to purchase a DEM or even create one from scratch! In this first attempt, you can see the wider area close to the #Amynteo mine (Western Macedonia, #Greece). It is worth noting that the exploitation of such a product will need further examination and improvements as well as a validation in order to be utilized in a #geospatial analysis, yet the result seems quite promising showing the #landscape changes at the #Amynteo #mine! In the following animation you can see the comparison between the #EU-DEM (left) and the #DEM that i have produced using #Sentinel-1 #SAR #SLC images (right). The entire workflow for processing Sentinel-1 satellite data was conducted using the European Space Agency's (#ESA) open software, #SNAP. The analysis contains processed #Copernicus data. The visualization of these data was implemented using #ArcGIS Pro software. #radar #elevation #InSAR #satellite #EarthObservation #GIS #WesternMacedonia
