Optimization of Threshold Ranges for Rapid Flood Inundation Mapping by Evaluating Backscatter Profiles of High Incidence Angle SAR Images

引用

International Journal of Disaster Risk Science 2012年第2期3卷 113-122页

作者： Panchagnula Manjusree L.Prasanna kumar Chandra mohan Bhatt Goru Srinivasa Rao Veerubhotla Bhanumurthy Disaster Management Support Group Remote Sensing Applications AreaNational Remote Sensing CentreIndian Space Research Organization(ISRO)BalanagarHyderabad 500625India

Rapid satellite-based flood inundation mapping and delivery of flood inundation maps during a flood event can provide crucial information for planners and decision makers to prioritize relief and rescue operations. The present study is undertaken to optimize the threshold ranges for the classification of flood water in Synthetic Aperture Radar(SAR) images(of 20° to 49° incidence angles) for quick flood inundation mapping and response during flood disasters. This is done through assessing the signature of flood water in Horizontal transmit and Horizontal received(HH), Horizontal transmit and Vertical received(HV), Vertical transmit and Horizontal received(VH), and Vertical transmit and Vertical received(VV) polarization radar data. The mean backscattering signature profiles of various water bodies were analyzed to discriminate flood water from other water bodies. The study shows that there is better demarcation of land-water surface in HH polarization. VV polarization has the potential to identify partially submerged features, which can be useful in flood damage assessments. The backscatter of flood water in HV and VH is the same and both HV and VH polarizations are adequate for the mapping of flood water. At near range to far range,-8 to-12 d B,-15 to-24 d B, and-6 to-15 d B can be used as optimum ranges for the classification of flood water in HH, HV, and VV polarizations. These optimum threshold ranges can be applied to the automation of flood mapping using SAR images in near-real time, where much time was often spent on finding the thresholds in order to produce flood inundation maps in a short time from the onset of flood disasters and deliver such maps to the concerned agencies.

作者： Guddappa Mahalingappa Devagiri Anil kumar Khaple Siddagangaiah mohan Puttanaik Venkateshamurthy Sanjay Tomar Arkalgud Nagaraja Arunkumar Geeta Joshi Department of Natural Resource Management College of Forestry University of Agricultural and Horticultural Sciences Department of Horticulture College of AgricultureUniversity of Agricultural Sciences ICRAF-South Asia NASC Pusa Campus Division of Tree Improvement Institute of Wood Science and Technology

Canopy gaps play a significant role in maintaining structure and composition of tropical forests. This study was carried out in tropical evergreen forests of central Western Ghats in India to understand the influence of canopy gap size and the relationship of gap regime attributes to diversity measures and regeneration. The average gap size in the study area was found to be 396 m2 and around half of gaps were 4–8 years old. Gaps created by natural single tree fall were smaller in size but significantly higher in number. Diversity and regeneration of woody species were compared with canopy gaps and intact vegetation. Species richness and diversity was higher in gaps than in intact vegetation. Macaranga peltata, a shade intolerant species dominated gaps while intact vegetation was dominated by shade tolerant Kingiodendron *** size significantly influenced species diversity and regeneration. Gap area and age were significantly and negatively correlated with diversity measures but positively correlated with regeneration. Among all the attributes of gaps, regeneration was significantly positively correlated with light intensity. Gaps maintained species diversity and favored regeneration of woody species. In addition to gap size and age, other gap ecological attributes also affected species diversity and regeneration.

Multi-polarized Radarsat-2 satellite sensor in assessing forest vigor from above ground biomass

引用

Journal of Forestry Research 2018年第4期29卷 1127-1133页

Accurate estimates of forest biomass are increasingly important in relation to sequestration of carbon by forest trees. Satellite remote sensing is a useful tool for biomass estimation and monitoring of forest ecological processes. Microwave synthetic aperture radar （SAR） can increase the accuracy of estimations of forest biomass in comparison to optical remote sensing, due to the unique capacities of SAR, including high penetrability, volumetric scattering, interaction with surface roughness, and dielectric property. We studied the potential of multi-polarized C-band Radarsat-2, a SAR technology, with HH, HV and VV polarization for estimating biomass of moist tropical Indian forest. Backscatter values are correlated with fieldbased biomass values and axe regressed to generate models for estimating biomass. HH polarization provided maximum information regarding tree biomass. A coefficient of determination of 0.49 was calculated for HH polarized C-band image with in situ measurements. An exponential model was proved to be best suited for estimating forest biomass. Correlation of 0.62 and RMSE of 24.6 t ha-1 were calculated for the relationship between estimated and predicted biomass values for the best fit model. The aver- age absolute accuracy of the model was 61%, while Willmott＇s index of agreement was 0.87. Results suggest that most of the biomass of the area ranged within 70 t ha-1 a probably due to the saturation of C-band around 60-70 t ha-1 for tropical forests.

作者： Rajpal Singh Punia Reetu Kundu Jagdish Chander Sudesh kumar Arya Uma Handa Harsh mohan Department of Pathology Government Medical College and Hospital Department of Microbiology Government Medical College and Hospital Department of Ophthalmology Government Medical College and Hospital

AIM: To determine the causative agents of fungal keratitis and study the predisposing factors over a period of ten years in a single tertiary care hospital. ·METHODS: A retrospective analysis of fungal corneal ulcers was done from 2003-2012. Patients’ clinical data were noted from the file records. Correlation of histopathological diagnosis was done with the report on fungal culture. · RESULTS: Mycotic keratitis was established in 44 cases by a positive fungal culture. Direct microscopic examination of potassium hydroxide(KOH) mounts revealed fungal elements in 39 cases while 40 cases showed fungus on Gram stained smears. Males(54.55%) were more commonly affected than the females(45.45%). The age ranged from 18 to 82 years. Most common age group to be involved was 41-60 years. Predisposing risk factors were seen in 34(77.27%) cases. Most common findings on clinical examination were anterior chamber reaction and conjunctival injection seen in all the cases. Other common findings were stromal infiltration and hypopyon seen in 20(45.45%) and 18(40.91%) cases respectively. On histopathological examination the fungus was typed,as aspergillus in 34 cases while no definite typing was possible in 10 cases. The predominant isolate was aspergillus flavus(59.09%) followed by fusarium(15.91%). Mixed fungal and bacterial infection was seen in 3(6.82%) cases. ·CONCLUSION: Although culture is the gold standard for definitive diagnosis of fungal keratitis,direct microscopic examination of corneal scrapings or histomorphological evaluation of biopsies allow a rapidpreliminary diagnosis. Early administration of antifungal treatment helps in preventing dreadful complications.

Background: Frey’s procedure involves both drainage and resection of the pancreas in subjects with chronic calcific pancreatitis(CCP). The procedure may affect the pancreatic endocrine function after surgery. The present study was to evaluate the effect of Frey’s procedure on both beta and alpha cell function in CCP ***: Thirty CCP patients who underwent Frey’s procedure were included. According to the glycemic status, patients were divided into the diabetes mellitus(DM), prediabetes, and normal glucose tolerance(NGT) groups. Islet cell function was assessed before and 3 months after ***: At baseline, there was a significant difference in beta cell function among the three groups [NGT group 1.71(1.64–2.07) vs prediabetes group1.50(0.83–1.61) vs DM group 0.33(0.12–0.55), P < 0.0001], but the insulin resistance was not different among them. Post glucose hyperglucagonemia representing alphacell dysfunction during oral glucose tolerance test was present in all of them, but showed no significant difference [NGT group 0.15(0.06–0.31) vs prediabetes group 0.32(0.05–0.70) vs DM group 0.07(0.02–0.18), P = 0.20]. Frey’s procedure did not change beta cell function and insulin resistance. However, alphacell dysfunction deteriorated after surgery [0.10(0.03–0.27) vs 0.33(0.09–0.68), P = 0.004].Conclusions: Although Frey’s procedure does not affect the beta cell function and insulin resistance in CCP patients, the alpha-cell dysfunction deteriorates after surgery.
