Book Description
People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be described and future land change can be projected using land-change models (LCMs). LCMs are a key means for understanding how humans are reshaping the Earth's surface in the past and present, for forecasting future landscape conditions, and for developing policies to manage our use of resources and the environment at scales ranging from an individual parcel of land in a city to vast expanses of forests around the world. Advancing Land Change Modeling: Opportunities and Research Requirements describes various LCM approaches, suggests guidance for their appropriate application, and makes recommendations to improve the integration of observation strategies into the models. This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes. Advancing Land Change Modeling's recommendations for assessment of future data and research needs will enable model outputs to better assist the science, policy, and decisionsupport communities.

Book Description
Abstract: "Ecological dynamics in human-influenced landscapes are strongly affected by socioeconomic factors that influence land-use decision making. Incorporating these factors into a spatially-explicit landscape-change model requires integrating multidisciplinary data. In order to study the effects of land use on landscape structure in regions such as the Little Tennessee River basin in western North Carolina and the Olympic Peninsula of Washington state, we have developed the Land Use Change Analysis System or LUCAS for UNIX-based workstations. The map layers used by LUCAS are derived from remotely-sensed images, census and ownership maps, topographical maps, and outputs from econometric models. These map layers are stored, displayed, and analyzed using a public-domain Geographic Information System (GIS). Simulations using LUCAS generate new maps of land cover representing the amount of land-cover change so that issues such as biodiversity conservation, assessing the importance of landscape elements to meet conservation goals, and long-term landscape integrity can be addressed."

Book Description
During FY15 staff from the Remote Sensing Applications Center (RSAC) developed an online survey to assess Forest Service land cover disturbance information needs. There were 172 respondents to the survey across a wide and representative spectrum of potential Landscape Change Monitoring System (LCMS) information users. The respondents expressed a strong and growing need for land cover change information. Major drivers of their need include federal and agency requirements and initiatives, as well as local initiatives. The top three major business areas for land cover change monitoring were identified as 1) Forest Health, 2) Watershed Health, and 3) Forest and Vegetation Management. Forest characteristics of canopy cover, forest and non-forest groups, and forest structure were identified as the most important parameters to monitor. In addition, causative agents of change such as fire, invasive species, insects and disease, and climate change, were very important to understand and should be provided as part of the land cover change information. The data needs of the respondents covered a wide spectrum; however, the survey results clearly show a tendency towards a spatial extent of roughly a National Forest, with a 30 m pixel size data granularity, and a 1-year revisit time. The desired analysis resolution (i.e., the level at which the change information is summarized) was at the District-to-National Forest levelalthough a large number of respondents expressed a preference to summarize the data themselves to other resolutions. In addition to information about the presence/absence of land cover change, the respondents indicated that the causative agent of disturbance and trend analysis information would be the most useful additional analysis products. Finally, an overwhelming majority desired access to the data layers used to derive the land cover change products by downloading the data from corporate information systems.

Book Description
Analyzes how well the Natural Heritage Classification (NHC) and the Anderson Classification systems classify an area based on Landsat imagery and a modern (circa 2002) land cover map created by the Canandaigua Lake Watershed Council (CLWC). A geographic information system (GIS) is used to reclassify the Landsat imagery into land uses and land covers based on the two classification systems and to produce tables expressing the accuracy of each system as compared to the truth image.
