Floods are one of the most devastating natural calamities affecting millions people and causing damage all around globe. Flood models remote sensing imagery often used to predict understand flooding. An increasing number earth observation satellites producing data at a rate that far outpaces our ability manually extract meaningful information from it, motivating surge in research on automatic feature detection satellite using machine learning deep algorithms automate flood mapping so large...
Global environmental change scenarios have typically provided projections of land use and cover for a relatively small number regions or using coarse resolution spatial grid, only few major sectors. The coarseness global projections, in both thematic dimensions, often limits their direct utility at scales useful management. This paper describes methods to downscale land-use land-cover from the Intergovernmental Panel on Climate Change's Special Report Emission Scenarios ecological...
Information on future land‐use and land‐cover (LULC) change is needed to analyze the impact of LULC ecological processes. The U.S. Geological Survey has produced spatially explicit, thematically detailed projections for conterminous United States. Four qualitative quantitative scenarios were developed, with characteristics consistent Intergovernmental Panel Climate Change (IPCC) Special Report Emission Scenarios (SRES). four quantified (A1B, A2, B1, B2) served as input forecasting (FORE‐SCE)...
Anthropogenic land use will likely present a greater challenge to biodiversity than climate change this century in the Pacific Northwest, USA. Even if species are equipped with adaptive capacity migrate face of changing climate, they encounter human-dominated landscape as major dispersal obstacle. Our goal was identify, at ecoregion-level, protected areas close proximity lands higher likelihood future land-use conversion. Using state-and-transition simulation model, we modeled spatially...
Abstract The frequency and extent of wildfires have increased in recent decades with immediate cascading effects on water availability many regions the world. Precipitation is used as primary input to hydrologic models a critical driver post‐wildfire hazards including debris flows, flash floods, water‐quality effects, reservoir sedimentation. These are valuable tools for understanding response wildfire but require accurate precipitation data at suitable spatial temporal resolutions....
Carbon storage potential has become an important consideration for land management and planning in the United States. The ability to assess ecosystem carbon balance can help managers understand benefits tradeoffs between different strategies. This paper demonstrates application of Land Use Scenario Simulator (LUCAS) model developed local-scale at Great Dismal Swamp National Wildlife Refuge. We estimate net by considering past disturbances resulting from storm damage, fire, actions including...
The U.S. Census Bureau provides decadal demographic data collected at the household level and aggregated to larger enumeration units for anonymity purposes. Although this system is appropriate dissemination of large amounts national data, often boundaries do not reflect distribution underlying statistical phenomena. Conventional mapping methods such as choropleth mapping, are primarily employed due their ease use. However, analytical drawbacks well known ranging from (1) artificial...
Spatially-explicit state-and-transition simulation models of land use and cover (LULC) increase our ability to assess regional landscape characteristics associated carbon dynamics across multiple scenarios. By characterizing appropriate spatial attributes such as forest age land-use distribution, a model can more effectively simulate the pattern spread LULC changes. This manuscript describes methods input parameters Land Use Carbon Scenario Simulator (LUCAS), customized utilized relative...
Human population counts are collected and commonly displayed uniformly across areas, such as U.S. Census Bureau block-groups tracts. The limitation inherent in this type of representation is the assumption that people evenly distributed each areal unit, when actuality many areas parks, open spaces, industrial zones uninhabited. Geological Survey (USGS) has developed a geospatial tool uses 'dasymetric' mapping method to redistribute census values homogenous, inhabited, zones, enhancing...
Detecting, quantifying, and projecting historical future changes in land use cover (LULC) has emerged as a core research area for the U.S. Geological Survey (USGS). Changes LULC are important drivers of to biogeochemical cycles, exchange energy between Earth's surface atmosphere, biodiversity, water quality, climate change. To quantify rates recent change, USGS Land Cover Trends project recently completed unique ecoregion-based assessment late 20th century change western United States....
Local planning is insufficient for regional catastrophes; exercises are needed to test emergency plans and decision-making structures. The ARkStorm scenario would trigger a mass evacuation that be complicated by the social characteristics of populations [e.g., vehicle ownership, age, poverty, English language limitation (ELL), shelter needs]. Land cover data dasymetric mapping improves allocation residential their flood zone in 21 counties California. Numbers concentrations county, urban,...
