Journal: :The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences 2022

Abstract. In this paper, we propose a point-level foreground-background separation technique for the segmentation of measurement sequences Non-repetitive Circular Scanning (NRCS) Lidar sensor, which is used as 3D surveillance camera mounted in fixed position. We show that by applying NRCS technology, can overcome various limitations rotating multi-beam sensors, such low vertical resolution, dis...

Currently, unmanned aerial vehicles (UAVs) are widely used due to their low cost and flexibility. In particular, they in remote sensing as airborne platforms for various instruments. Here, we investigate the capability of a conical scanning radar operated scatterometer mounted on high-altitude UAV perform sea surface wind retrieval based an appropriate geophysical model function (GMF). Increasi...

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and...

Water has a significant role in society, whether through human consumption or agricultural use. The Lavaca Watershed is an community affected by nonpoint source pollution, and water quality protection of high concern. Beef cattle operations are linked to pollution which contaminates surrounding sources. If proper grazing management practices not used, wastes from the operation impair area. Land...

جمع‏آوری رواناب برای به‌ حداقل‌رساندن تلفات و تقویت ذخایر آبی در حوضه‏های آبخیز‌ استفاده می‌شود. کشورهایی که مانند برخی مناطق ایران کمبود آب دارند، با توزیع نامناسب بارندگی مواجه‌اند. با گسترش مصرف منابع آبی، استفادۀ اصولی از رواناب به‌دست‌آمده از بارش می‏تواند در جهت رفع مشکل کمبود آب مؤثر واقع شود. به‏منظور برآورد رواناب در حوضه‏های آبخیز روش‏های تجربی و مدل‏های ریاضی مختلفی وجود دارد. یکی از...

An accurate Modulation Transfer Function (MTF) is essential for Synthetic Aperture Radar (SAR) wave spectra retrieval. This study aimed to investigate the performance of a quad-polarized retrieval algorithm based on fully polarimetric SAR image data using improved tilt MTF and considering influence wind speed. The key factor in scheme from (Vertical–Vertical (VV), Horizontal–Horizontal (HH), Ve...
