When applying remotely sensed data, the information needs dictate the selection of data and analysis methods. Whether the scope of the application is over large areas or individual trees, a project typically must address logistical issues related to data selection and subsequent processing. Logistical issues include the scale at which the target must be measured (which will determine the appropriate sources of imagery), the attributes of interest, cost, timeliness, and repeatability. In this report, we present landscape-level and tree-level information needs and synthesize approaches for detection and mapping of mountain pine beetle (Dendroctonus ponderosae Hopkins) red-attack damage with remotely sensed data, from a forest management and disturbance mitigation perspective. The goal of this communication is to provide the reader with an understanding of the nuances and realities of using remotely sensed data to fulfill a specific information need: from identifying the actual information need, selecting the image data and analysis methods, to producing desired outputs. Although demonstrated in the context of mountain pine beetle, many of the issues, considerations, and decision points raised here are applicable to other forest management and monitoring applications of remotely sensed data.
