    Remote Sensing, Vol.13, No.1, 2024; 36 Views, 0 PDF Downloads

    DOI: https://doi.org/10.18282/rs.v13i1.3463

    This article explored mineral resources and their relation to structural settings in the Central Eastern Desert (CED) of Egypt. Integration of remote sensing (RS) with aeromagnetic (AMG) data was conducted to generate a min_x005feral predictive map. Several image transformation and enhancement techniques were performed to Landsat Operational Land Imager (OLI) and Shuttle Radar Topography Mission (SRTM) data. Using band ratios and oriented principal component analysis (PCA) on OLI data allowed delineating hydrothermal alteration zones (HAZs) and highlighted structural discontinuity. Moreover, processing of the AMG using Standard Euler deconvolution and residual magnetic anomalies successfully revealed the subsurface structural features. Zones of hydrothermal alteration and surface/subsurface geologic structural density maps were combined through GIS technique. The results showed a mineral predictive map that ranked from very low to very high probability. Field validation allowed verifying the prepared map and revealed several mineralized sites including talc, talc-schist, gold mines and quartz veins associated with hematite. Overall, integration of RS and AMG data are powerful techniques in revealing areas of potential mineralization involved with hydrothermal processes.

    Urban Road Extraction High resolution remotely sensed imagery with Gabor texture and geometrical Features

    by Hualong Hu, Bing Wu, Shaomei Huang

    Remote Sensing, Vol.13, No.1, 2024; 58 Views, 0 PDF Downloads

    DOI: https://doi.org/10.18282/rs.v13i1.3466

    Through the feature analysis of the frequency curve , The paper proposed a new method which integrated Gabor texture and geometrical features in the urban road Ction from high resolution remotely sensed imagery. in the experiment, the texture features in different frequencies and Different directions were obtained by a given bank of Gabor filters,andthen K-means clus Tering method is applied for imagery segmentation. The morphological methods were utilized to separate the road objects from Non-^oadobjects, and the geometrical features were applied to take out the non-road. Then the extracted roads were regulated by mathematical morphology. The result showed this proposed method could effectively extract the urban road information from high resolution Remo Tely sensed imagery.

    Spectral Unmixing of Hyperspectral Images in the Presence of Small Targets

    by Sylvain Ravel, Caroline Fossati, Salah Bourennane

    Remote Sensing, Vol.13, No.1, 2024; 29 Views, 0 PDF Downloads

    DOI: https://doi.org/10.18282/rs.v13i1.3467

    Generally, the content of the hyperspectral image pixel is a mixture of the reflectance spectra of the different components in the imaged scene. In this paper, we consider a linear mixing model where the pixels are linear combina_x005ftions of those reflectance spectra, called endmembers, and linear coefficients corresponding to their abundances. An important issue in hyperspectral imagery consists in unmixing those pixels to retrieve the endmembers and their corresponding abundances. We consider the unmixing issue in the presence of small targets, that is, their endmembers are only contained in few pixels of the image. We introduce a thresholding method relying on Non-negative Matrix Factorization to detect pixels containing rare endmembers. We propose two resampling methods based on bootstrap for spectral unmixing of hyperspectral images to retrieve both the dominant and rare endmembers. Our experimental results on both simulated and real world data demonstrate the efficiency of the proposed method to estimate correctly all the endmembers present in hyperspectral images, in particular the rare endmembers.

    Integrating Optical and Microwave Satellite Observations for High Resolution Soil Moisture Estimate and Applications in CONUS Drought Analyses

    by Donglian Sun, Yu Li, Xiwu Zhan, Chaowei Yang, Ruixin Yang

    Remote Sensing, Vol.13, No.1, 2024; 38 Views, 0 PDF Downloads

    DOI: https://doi.org/10.18282/rs.v13i1.3468

    In this study, optical and microwave satellite observations are integrated to estimate soil moisture at the same spatial resolution as the optical sensors (5km here) and applied for drought analysis in the continental United States. A new refined model is proposed to include auxiliary data like soil texture, topography, surface types, accumulated pre_x005fcipitation, in addition to Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) used in the traditional universal triangle method. It is found the new proposed soil moisture model using accumulated precipitation demonstrated close agreements with the U.S. Drought Monitor (USDM) spatial patterns. Currently, the USDM is providing a weekly map. Recently, “flash” drought concept appears. To obtain drought map on daily basis, LST is derived from microwave observations and downscaled to the same resolution as the thermal infrared LST product and used to fill the gaps due to clouds in optical LST data. With the integrated daily LST available under nearly all weather conditions, daily soil moisture can be estimated at relatively higher spatial resolution than those traditionally derived from passive microwave sensors, thus drought maps based on soil moisture anomalies can be obtained on daily basis and made the flash drought analysis and monitoring become possible.

ANNOTATED VOLCANO: A VOLCANO'S SHAPE CAN TELL YOU HOW IT WILL ERUPT

2018-09-12

YOU GET A double feature for the latest Annotated Volcano. Why two volcanoes? I wanted to explain the difference between two different shapes of volcanoes: the archetype stratovolcano and the massive shield volcano. Why would two volcanoes take such different forms? It boils down to the flavor and form of the stuff that comes out the top.

Stratovolcano

Mexico's Popocatépetl is an example of what volcanologists call a stratovolcano*, with a well-formed conical shape and a crater/vent at the top of the volcano. You can see that shape in the profile shot of the volcano (taken from the Earth's surface; below) with steep slopes. The average slope heading up the sides of the volcano are ~25 percent with a maximum of 63 percent in the steepest bits. From the "base" level of ~3500 meters (11,400 feet) to the summit you gain 1635 meters (~5,300 feet). All in all, hiking this volcano would definitely be a slog, especially as you approach the summit and the slopes get even steeper. You can also notice a nearly circular shape to the volcano (above), with paths of debris heading in all directions from the summit crater.

NOBODY KNOWS WHERE THIS BIG RAFT OF PUMICE CAME FROM

2018-09-12

Last week, a Royal New Zealand Air Force flight spotted a new pumice raft in the middle of the Pacific ocean to the west of Tonga. Pumice rafts are floating islands of pumice created during a submarine volcanic eruption and they can persist for months or longer. This raft was seen by aircraft and satellite in an area with no known volcanoes. However, from the looks of the raft, it might be a long way from home. The pumice is strung out in long streamers, suggesting it has been smeared and distorted by ocean currents and weather as the pumice floats along the ocean surface.

UPDATE: A number of people have asked a good question: how big is this raft? Based on the satellite images, it could be tens of kilometers long, but very narrow (hundreds to tens of meters?). It is a little tricky to get a confident size because of the resolution of the images.
