The overall objective of this proposal is to integrate state-of-the-art remote sensing techniques with innovative methods for understanding wildlife movement behavior. Our research is timely given the rapid development of remote sensing technology, combined with new loggers for tracking wildlife locations. In particular, my program will focus on two primary areas of methodological research: 1) models for quantifying wildlife space use and 2) methods for understanding inter-individual interactions, for example human disturbance of wildlife. My team and I will apply the methods we develop to applied research problems in wildlife spatial ecology through local, national, and international collaborations. Understanding space-time patterns in high-resolution wildlife tracking data is a major methodological challenge in GIScience. A key limitation of current methods is the ability to characterize relationships between movement patterns and environmental change. When we fail to capture how wildlife respond to dynamic environmental conditions, we are limited in our ability to make sound decisions for management or conservation activities. Therefore, new methods for combining high resolution wildlife tracking data with remotely sensed data are necessary to better capture and understand how patterns of wildlife movement relate to dynamic, rapidly changing environments. Current methods for integrating wildlife tracking data with remotely sensed data typically use single-date or single-satellite composites, and therefore, remain limited in their ability to capture fine-scale spatial and temporal changes in the environment. Therefore, satellite data fusion - combining satellite data from multiple sensors - represents a major opportunity for improved understanding in wildlife movement studies. My program emphasizes the training of HQP. Specifically, my proposal will support 13 current and future HQP (undergraduate, graduate, technical staff), who will be trained in GIS, remote sensing, and wildlife conservation. My trainees are taught a variety of technical skills which are highly marketable within and outside of academia. Our work will be published in high-impact scientific journals and presented at national and international academic conferences. We will achieve broad societal impact by working with local, national, and international partners in applied wildlife conservation and through the development of free and open source software tools for geospatial analysis.

该提案的总体目的是将最新的遥感技术与了解野生动植物运动行为的创新方法相结合。鉴于遥感技术的快速发展，以及用于跟踪野生动植物位置的新伐木者的迅速发展，我们的研究是及时的。特别是，我的计划将重点关注方法论研究的两个主要领域：1）用于量化野生动植物空间使用的模型和2）用于理解个体间相互作用的方法，例如人类对野生动植物的干扰。我和我的团队将通过本地，国家和国际合作将我们开发的方法应用于野生动植物生态学的应用研究问题。在高分辨率野生动植物跟踪数据中了解时空模式是司法的主要方法论挑战。当前方法的关键局限性是能够表征运动模式与环境变化之间的关系。当我们无法捕捉野生动植物对动态环境条件的反应时，我们的能力有限于为管理或保护活动做出明智的决策。因此，为了更好地捕获和理解野生动植物运动模式如何与动态，快速变化的环境相关联，需要将高分辨率野生动物跟踪数据与远程感知的数据相结合的新方法。当前的野生动植物跟踪数据与远程感知数据的方法通常使用单日期或单卫星复合材料，因此，其捕获环境中的微尺度空间和时间变化的能力仍然有限。因此，卫星数据融合 - 结合了来自多个传感器的卫星数据 - 代表了改善野生动植物运动研究中理解的主要机会。我的计划强调了HQP的培训。具体来说，我的建议将支持13个现任和未来的HQP（本科，研究生，技术人员），他们将接受GIS，遥感和野生动植物保护的培训。我的学员被教授了各种技术技能，这些技术技能在学术界内外都可以推销。我们的工作将在高影响力的科学期刊上发表，并在国家和国际学术会议上发表。我们将通过与当地，国家和国际合作伙伴合作进行野生动植物保护以及开发免费和开源的软件工具进行地理空间分析，从而实现广泛的社会影响。
