LANDFIRE 2014 (140) NGDA Products

LANDFIRE (LF) 2014 incorporates landscape change and disturbances, such as wildland fire, fuel and vegetation treatments, insects and disease, storm damage, and invasive plants that occurred in 2013 and 2014. This update includes: responses to vegetation successional change in forested types revisions to address discrepancies between map products and known field conditions The LF 2014 update also: supports wildland fire and natural resource management, planning, research, analysis, and assessments uses Landsat imagery, point, and polygon data 2013-2014 incorporates new or updated institutional data sources changes data only where vegetation changed due to successional change or disturbance updates fuel products based on vegetation products The LF 2014 update strategy applies a consistent approach to combine geospatial data depicting areas of disturbance with Remote Sensing of Landscape Change (RSLC) derived data to develop the disturbance layers. Data from combinations of Landsat satellite imagery, fire program data (e.g., Monitoring Trends in Burn Severity (MTBS)), cooperator-provided field data, and other ancillary data (e.g., Protected Area Database (PAD)) are used to locate and characterize large wildfires.

LANDFIRE（LF）2014数据集整合了2013至2014年间发生的各类景观变化及扰动事件，包括野火、燃料管理与植被修复措施、病虫害、风暴破坏以及入侵植物等。本次更新包含两项内容：针对森林类型植被演替变化的响应修订，以及解决地图产品与实际野外调查数据间不一致问题的修正。
LANDFIRE 2014更新还具备以下特点：支持野火与自然资源管理、规划、研究、分析及评估工作；采用Landsat遥感影像、点与多边形数据完成2013-2014年度更新，并纳入新增或更新的机构数据源；仅在植被因演替变化或扰动发生改变的区域执行数据更新；基于植被产品同步更新燃料相关产品。
LANDFIRE 2014的更新策略采用统一方法，将描绘扰动区域的地理空间数据与景观变化遥感（Remote Sensing of Landscape Change, RSLC）衍生数据相结合，以生成扰动图层。研究结合使用Landsat卫星影像、火灾项目数据（如燃烧严重度监测趋势（Monitoring Trends in Burn Severity, MTBS））、合作方提供的野外调查数据，以及其他辅助数据（如保护区数据库（Protected Area Database, PAD）），用于定位大型野火并刻画其特征。
