Abstract

ABSTRACT Haze over Sumatera and Kalimantan has been a prolonged trans-boundary issue in South East Asia mainly due to setting fire to drained peatland. At present, fire sources (i.e. hotspots) are located based on satellite data. Sensors such as MODIS and AVHRR detect extremes in average temperatures of an area. The hotspots have low spatial resolution and large spatial footprints, thus making it harder to detect fires. This research proposed a ground-based spatial validation of satellite data based on crowdsourcing in order to obtain more accurate estimates of the location and severity of the fire. We developed an Android application for reporting and validating fires in peatlands. Crowd data collected were integrated with satellite hotspot data by the dashboard system as a monitoring platform for government agencies. The 110,888 hectares of Padang Island, in Riau Province, were chosen as the study area given its vulnerability to peatland fire and imminent danger of subsidence as the collateral effect of draining peatlands. Residents of Padang Island tested the use-case scenario of the app to assess its applicability. The study showed the potential use of mobile apps for local communities to help the government validate hotspots for haze mitigation.

基于位置的雾霾缓解的众包热点验证和数据可视化

苏门答腊和加里曼丹的雾霾一直是东南亚地区长期存在的跨境问题，其主要原因是排干的泥炭地着火。目前，火源(即热点)的定位是基于卫星数据。像MODIS和AVHRR这样的传感器可以探测到一个地区平均温度的极端值。热点的空间分辨率低，空间足迹大，因此更难探测到火灾。本研究提出了一种基于众包的卫星数据地基空间验证方法，以便更准确地估计火灾的位置和严重程度。我们开发了一个用于报告和验证泥炭地火灾的Android应用程序。通过仪表盘系统将采集到的人群数据与卫星热点数据进行整合，作为政府机构的监控平台。廖内省巴东岛的110,888公顷被选为研究区域，因为它容易受到泥炭地火灾的影响，而且由于泥炭地排水的附带影响，它有迫在眉睫的下沉危险。巴东岛的居民测试了应用程序的用例场景，以评估其适用性。该研究表明，当地社区可以使用移动应用程序来帮助政府确定缓解雾霾的热点地区。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
