Shading aware DSM generation from high resolution multi-view satellite images

Geo-spatial Information Science
In many cases, the Digital Surface Models (DSMs) and Digital Elevation Models (DEMs) are obtained with Light Detection and Ranging (LiDAR) or stereo matching. As an active method, LiDAR is very accurate but expensive, thus often limiting its use in small-

Eutectic Mixtures of Inorganic and Organic Adamantane‐Type Compounds With Strongly Nonlinear Optical Properties

Small, EarlyView.
ABSTRACT We report a new concept to lower the melting temperature (Tm) of inorganic‐organic hybrid adamantane‐based cluster compounds by forming unprecedented eutectic cluster mixtures with organic adamantane derivatives. Blending of clusters of the type [(p‐MeC6H4Si(CH2SnPhE)3] (E = S, Se, Te) with (3‐F‐4‐Me‐C6H3)3Ad, (3‐F‐4‐Me‐Ph)4Ad, and (4‐MeO‐C6H4)

Diorganotelluride···N Chalcogen Bonds: Analysis and Tuning of Two σ‐Holes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Two new chalcogen bond aggregates were analyzed using single crystal X‐ray diffraction: an oligomeric ChB aggregate between bis(pentafluorophenyl) telluride and DABCO, and a monoadduct between (pentafluorophenyl)(phenyl) telluride and quinuclidine. In addition to some of the shortest intermolecular Te···N contacts reported, these structures provide ...

Enhancing Urban Digital Elevation Models Using Automated Computer Vision Techniques [PDF]

, 2010
In recent years Digital Elevation Models (DEM) gained much interest because of their high capability to give information about urban regions. DEM can be used for detailed urban monitoring, change and damage detection purposes.

A Weighted Image-Point-Measurement Method of Laser Altimetry Points for Improving Laser-Altimetry-Data-Assisted Positioning Accuracy of Small-Satellite Images

Remote Sensing
For small-satellite imagery, traditional image points derived from the direct back-projection of laser altimetry points onto the imagery often exhibit deviations of tens of pixels or more, owing to the relatively limited attitude and orbit determination ...

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

Boreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

Building Height Estimation from Stereo Satellite Images Using Contour Vector Registration [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Accurate building height estimation plays a crucial role in large-scale 3D urban reconstruction. However, conventional stereo matching approaches often suffer from mismatches around building edges, leading to unreliable height retrieval in dense urban ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Multi‐Spectral Gaussian Splatting with Neural Color Representation

Computer Graphics Forum, EarlyView.
Abstract 3D Gaussian Splatting (3DGS) [KKLD23] has transformed novel‐view synthesis from RGB images, yet remains restricted to the visible spectrum. Many applications, including agricultural monitoring, rely on multi‐spectral imaging, where spectral camera alignment and scalability pose major challenges.
