We present a new method for remote sensing image segmentation, which utilizes both spectral and texture information. Linear filters are used to provide enhanced spatial patterns. For each pixel location, we compute combined features using local histograms, concatenate histograms of all input bands. regard feature as linear combination several representative features, corresponds segment. Segmentation is given by estimating weights, indicate segment ownership pixels. segmentation solutions...
Lakes and permafrost on Qinghai-Tibet Plateau (QTP) are both important indicators of climate change. Previous literatures have shown the usefulness optical remote sensing in lake expansion monitoring effectiveness synthetic aperture radar (SAR) interferometry (InSAR) retrieving deformation QTP. However, none them incorporated InSAR to investigate an event that may exhibit causal links between outburst degradation.

The cratered plains of Gusev traversed by Spirit are generally low‐relief rocky dominated impact and eolian processes. Ubiquitous shallow, soil‐filled, circular depressions, called hollows, modified craters. Rocks dark, fine‐grained basalts, the upper 10 m appears to be an impact‐generated regolith developed over intact basalt flows. Systematic field observations across identified vesicular clasts rare scoria similar original lava flow tops, consistent with inflated surface flows adjacent...

High-resolution (submeter) orbital imagers have opened up new possibilities for Mars topographic mapping with unprecedented precision. While the typical sensor model Martian orbiters has been linear-array charge-coupled device (CCD), High-Resolution Imaging Science Experiment (HiRISE) instrument is based on a more complicated structure involving combination of 14 separate CCDs. To take full advantage this high-resolution capability without compromising imaging geometry, we developed rigorous...

Permafrost in Qinghai–Tibet Plateau (QTP) has been suffering from global warming recent years, characterized by the deepening of permafrost active layer. Seasonal changes are usually reflected as ground surface deformation, which can be monitored multi-temporal interferometric synthetic aperture radar (MT-InSAR) technology. Owing to extreme environment QTP, there few ground-based deformational observation data available, and records monitoring MT-InSAR with validation limited. Here we...

The extent of the area covered by polar sea ice is an important indicator global climate change. Continuous monitoring Arctic concentration (SIC) primarily relies on passive microwave images. However, images have coarse spatial resolution, resulting in SIC production with significant blurring at ice–water divides. In this article, a novel multi-image super-resolution (MISR) network called progressive multiscale deformable residual (PMDRnet) proposed to improve resolution according...

Subglacial water bodies are critical components in analyzing the instability of Antarctic ice sheet. Their detection and identification normally rely on geophysical remote sensing methods such as airborne radar echo sounding (RES), ground seismic, satellite/airborne altimetry gravity surveys. In particular, RES surveys able to detect basal terrain with a relatively high accuracy that can assist mapping subglacial hydrology systems. Traditional processing for mostly their brightness...
