Semiautomated detection and mapping of vegetation distribution in the Antarctic environment using spatial-spectral characteristics of WorldView-2 imagery.

first_imgEffective monitoring of changes in the geographic distribution of cryospheric vegetation requires high-resolution and accurate baseline maps. The rationale of the present study is to compare multiple feature extraction approaches to remotely mapping vegetation in Antarctica, assessing which give the greatest accuracy and reproducibility relative to those currently available. This study provides precise, high-resolution, and refined baseline information on vegetation distribution as is required to enable future spatiotemporal change analyses of the vegetation in Antarctica. We designed and implemented a semiautomated customized normalized difference vegetation index (NDVI) approach for extracting cryospheric vegetation by incorporating very high resolution (VHR) 8-band WorldView-2 (WV-2) satellite data. The viability of state-of-the-art target detection, spectral processing/matching, and pixel-wise supervised classification feature extraction techniques are compared with the customized NDVI approach devised in this study. An extensive quantitative and comparative assessment was made by evaluating four semiautomatic feature extraction approaches consisting of 16 feature extraction standalone methods (four customized NDVI plus 12 existing methods) for mapping vegetation on Fisher Island and Stornes Peninsula in the Larsemann Hills, situated on continental east Antarctica. The results indicated that the customized NDVI approach achieved superior performance (average bias error ranged from ~6.44 ± 1.34% to ~11.55 ± 1.34%) and highest statistical stability in terms of performance when compared with existing feature extraction approaches. Overall, the accuracy analysis of the vegetation mapping relative to manually digitized reference data (supplemented by validation with ground truthing) indicated that the 16 semi-automatic mapping methods representing four general feature extraction approaches extracted vegetated area from Fisher Island and Stornes Peninsula totalling between 2.38 and 3.72 km2 (2.85 ± 0.10 km2 on average) with bias values ranging from 3.49 to 31.39% (average 12.81 ± 1.88%) and average root mean square error (RMSE) of 0.41 km2 (14.73 ± 1.88%). Further, the robustness of the analyses and results were endorsed by a cross-validation experiment conducted to map vegetation from the Schirmacher Oasis, East Antarctica. Based on the robust comparative analysis of these 16 methods, vegetation maps of the Larsemann Hills and Schirmacher Oasis were derived by ensemble merging of the five top-performing methods (Mixture Tuned Matched Filtering, Matched Filtering, Matched Filtering/Spectral Angle Mapper Ratio, NDVI-2, and NDVI-4). This study is the first of its kind to detect and map sparse and isolated vegetated patches (with smallest area of 0.25 m2) in East Antarctica using VHR data and to use ensemble merging of feature extraction methods, and provides access to an important indicator for environmental change.last_img read more

Lawyer Loses Appeals Over Indy Skyline Photo

first_img LAWYER LOSES APPEALS OVER INDY SKYLINE PHOTOBY DAVID STAFFORD for INDIANA LAWYERAn Indianapolis lawyer who defendants call a copyright troll lost his appeals against three people who successfully defended against his suits over use of one of his photos.Richard Bell owns the copyright to two Indianapolis skyline photos that are the subject of the suits – one a daytime picture and the other taken at night. He has sued hundreds of people for copyright infringement for allegedly using the copyrighted photos on websites without first paying him a $200 licensing fee.Bell sued Cameron Taylor and his computer business Taylor Solutions; Fred O’Brien and his company Insurance Concepts; and Shanna Cheatham and her real estate site ShannaSells.com, alleging copyright infringement, unfair competition and theft. Judge Tanya Walton Pratt in August 2014 granted summary judgment in favor of the defendants, and the 7th Circuit Court of Appeals affirmed Friday.Bell argued that summary judgment was improper because his affidavit and website price listing create a genuine dispute of material fact as to whether he suffered damages from the infringement. He contends that the District Court erred by making a credibility determination when it characterized Bell’s affidavit [stating the photos had a fair market value of $200] as an “unsupported assertion,” Judge Joel Flaum wrote for the panel.“Bell does not aver in his affidavit that he has ever actually had a buyer willing to pay $200 for his photo. Instead, he states that he ‘believes that the price of $200 is fair and reasonable and represents the fair market value. …” Without additional evidence, Bell’s subjective belief as to the fair market value of his photo is not enough to prove damages,” Flaum wrote in affirming summary judgment for the O’Brien and Cheatham defendants.Flaum wrote “Bell attempted to obfuscate the issue of damages by objecting to defendants’ motion to compel his sales records,” claiming they were irrelevant and confidential. “After the district court granted defendants’ motion to compel, Bell still did not produce any sales records; rather, he moved for a protective order, which the district court denied.”The panel also held the District Court properly denied as overbroad Bell’s discovery demands that included 11 years of income tax records from O’Brien and Cheatham.The 7th Circuit also affirmed the rulings in favor of the Taylor defendants. Bell wrongly complained that Taylor had used the daytime photo, and the District Court denied as untimely his motion to amend his complaint to correct that Taylor had used the nighttime photo.“The district court found that Bell was not diligent in discovering his mistake regarding which photo Taylor had actually posted. During discovery in April 2013, Taylor sent Bell a copy of the nighttime photo that he had posted and stated in his interrogatory answers that he had never used the daytime photo. Thus, the district court found that Bell was on notice that Taylor had used the nighttime photo, not the daytime photo identified in the complaint,” Flaum wrote. “Yet Bell failed to act on this information until March 12, 2014, well after the July 15, 2013, deadline for amending pleadings had passed. Further, the court pointed out that Bell filed his motion to amend just four weeks prior to the dispositive motions deadlines and at the close of discovery. Thus, granting Bell’s motion would cause further delay and prejudice to defendants by affecting the summary judgment schedule and potentially creating a need to reopen discovery. For these reasons, the district court denied Bell’s motion to amend.”Bell “contends that it was Taylor who delayed the proceedings by not being forthcoming about why he was denying Bell’s allegations. This argument fails because Taylor gave Bell adequate notice that he had not used the daytime photo and was not required to do more to help Bell correct his error,” the court wrote.The panel also affirmed the District Court ruling dismissing a subsequent case Bell filed against Taylor based on res judicata, holding that such a ruling would have little practical effect. “We decline Bell’s suggestion that we should use the limited resources of the judiciary in this manner,” Flaum wrote.The case is Richard Bell v.

Former Coal Plant Could Be Reborn as Offshore Wind Fabrication Facility

first_img FacebookTwitterLinkedInEmailPrint分享Southcoast Today:Turbine foundations will be built at Brayton Point in Somerset if Bay State Wind receives a Massachusetts contract for offshore wind, a company spokeswoman said Thursday.German steel maker EEW and Houston-based steel company Gulf Island Fabrication, which will provide foundations for the project, have selected the former Brayton Point [coal-fired] power plant as their manufacturing location, according to Lauren Burm, a spokeswoman for Orsted, one of Bay State Wind’s parent companies.Timothy Mack, who does business development in U.S. offshore wind for EEW, said the steel companies are negotiating a long-term lease for the entire Brayton Point property. “We think it’s one of the few long-term sites that…has long-term viability due to the quayside, the large acreage and the proximity to the sites,” he said.Another plus for Brayton Point is the shipping channel, according to Mack. The dredged channel that served the plant for some 30 years for coal delivery remains largely intact.Bay State Wind, a joint venture between Danish energy company Orsted and local energy company Eversource, is one of three projects competing in a state-supervised bidding process to supply offshore wind power to Massachusetts energy distribution companies. A 2016 state law requires the power companies to buy electricity from offshore wind.More: Brayton Point Chosen For Wind Turbine Foundation Factory Former Coal Plant Could Be Reborn as Offshore Wind Fabrication Facilitylast_img read more

UN chief recommends ministers, diplomats skip meeting due to coronavirus risks, letter

first_imgUN Secretary-General Antonio Guterres has recommended that ministers and diplomats skip a meeting in New York next month of the Commission on the Status of Women due to the coronavirus outbreak, according to a letter seen by Reuters on Friday.More than 7,000 people usually attend the annual meeting, officials said, which is dedicated to the promotion of gender equality and the empowerment of women. It is due to be held from March 9 to 20.However, in a letter to UN member states from the chair of the commission, Armenia’s UN Ambassador Mher Margaryan said Guterres had recommended that member states “shorten and scale down the session” and cancel dozens of side events. Topics : “He also strongly recommended that capital-based representatives refrain from traveling to headquarters for the session,” Margaryan wrote.The bureau of the Commission on the Status of Women proposed that member states agree to Guterres’ recommendations at a meeting on Monday.UN spokesman Stephane Dujarric said Guterres made the recommendations given the “fast-evolving situation” with the coronavirus and the need to “balance the UN’s critical work and public health concerns”.”The advice given by the secretary-general is based on inputs from the Senior Emergency Policy Team and very close consultations between the UN Medical Services and the World Health Organization,” Dujarric said.The flu-like virus that emerged from central China late last year has spread to about 60 countries, infected more than 85,000 people and killed almost 3,000, mostly in China.last_img read more
