The goal of this project is to develop a Geographic Information System (GIS)-based system to characterize and model the spread of the invasive Emerald Ash Borer (EAB, Agrilus planipennis Fairmaire) insect infestation currently rife in numerous parts of the province of Ontario. We plan to develop innovative methods to derive up-to-date information on ash tree locations and the extent (presence/absence) of EAB infestation. An object-oriented and knowledge-based hierarchical framework will be designed and implemented to identify individual ash trees from multi-source remotely sensed data using ArcGIS software, the most widely used GIS platform by Canadian municipalities. The spatial patterns of the EAB spread at both regional and local scales will be characterized and the key factors controlling the spread of the EAB beetles will be identified and explicitly included in the EAB spread model. An EAB risk map will be generated for the study sites and management options will be suggested. ****The outcome of this project will result in a better understanding of the risk associated with the spread of this destructive insect, and allow better informed decisions to be made regarding its detection, monitoring, and control, which will help to inhibit its spread and allow local municipalities to preserve biomass in their urban tree inventory. The methodology and framework that will be developed in this project will advance remote sensing science in individual tree crown delineation and species identification and geospatial modelling, and will be transferred to our industrial partner, Esri Canada, for potential commercialization among its municipal clients. Ultimately, this will lead to national and potentially international economic benefits. The project will also provide training opportunities for highly qualified personnel to enhance their prospects for employment upon the completion of their education programs.

该项目的目的是开发一个基于地理信息系统（GIS）的系统，以表征和建模入侵性翡翠灰Borer（EAB，Agrilus Planipennis Fairmaire）昆虫侵害目前在安大略省众多地区盛行。 我们计划开发创新方法，以获取有关灰树位置以及EAB侵扰程度（存在/不存在）的最新信息。将设计和实施一个面向对象和基于知识的层次结构框架，以使用ArcGIS软件（加拿大市政当局使用最广泛使用的GIS平台）从多源远程感知的数据中识别单个灰树。 EAB在区域和局部尺度上的扩散的空间模式将被表征，控制EAB甲虫扩散的关键因素将被识别并明确包含在EAB传播模型中。将为研究地点生成EAB风险图，并建议管理选项。 ****该项目的结果将更好地理解与这种破坏性昆虫传播相关的风险，并为其检测，监测和控制做出更好的明智决定，这将有助于抑制其。在其城市树库存中散布并允许当地市政当局保存生物量。 该项目将开发的方法和框架将推进各个树冠描绘和物种识别和地理空间建​​模的遥感科学，并将转移给我们的工业合作伙伴Esri Canada，以在其市政客户中进行商业化。最终，这将导致国家和潜在的国际经济利益。该项目还将为高素质的人员提供培训机会，以在完成教育计划后提高其就业前景。
