Pedestrian tsunami evacuation results for two tsunami-evacuation zones (standard and extreme) and three travel speeds (impaired, slow, and fast walk) for O'ahu, HI

This data release is comprised of a set of six time travel map shapefiles (two tsunami evacuation zones and three travel times) and three population exposure by travel time tables (residents, employees, and hotel visitors). The travel time map was generated using the Pedestrian Evacuation Analyst model from the USGS (https://geography.wr.usgs.gov/science/vulnerability/tools.html). The travel time

Land Use and Conservation Scenarios for California's 4th Climate Change Assessment

This dataset consists of modeled projections of land use and land cover for the State of California for the period 2001-2101. The Land Use and Carbon Scenario Simulator (LUCAS) model was initialized in 2001 and run forward on an annual time step to 2100. In total 9 simulations were run with 10 Monte Carlo replications of each simulation. Two base scenarios were selected from Sleeter et al., 2017 (

Californias Water Use Future Based on Scenarios of Land Use Change - Data Release

This dataset contains .csv and .tif image files in support of the conclusions published in "Mediterranean Californias water use future under multiple scenarios of developed and agricultural land use change" in the journal PLOS One. We used the USGS's LUCAS model to examine a broad suite of spatially explicit future land use scenarios and their associated county-level water use demand, including th

Historical Time-series Classification of Habitat for 1957, 1980 and 2015 in the Nisqually River Delta, Washington

This USGS Data Release represents geospatial and tabular data for the Nisqually River Delta historical habitat mapping. The data release was produced in compliance with the new 'open data' requirements as a way to make the scientific products associated with USGS research efforts and publications available to the public. The dataset consists of 9 separate items: 1. Forest Change (raster datase

Land-use and Land-cover Projections for California's 4th Climate Assessment

This dataset consists of modeled projections of land use and land cover for the State of California for the period 1970-2100. For the 1970-2001 period, we used the USGS's LUCAS model to "backcast" LULC, beginning with the 2001 initial conditions and ending with 1970. For future projections, the model was initialized in 2001 and run forward on an annual time step to 2100. In total 5 simulations wer

Data - Forest harvest patterns on private lands in the Cascade Mountains, Washington, USA

Forests in Washington State generate substantial economic revenue from commercial timber harvesting on private lands. To investigate the rates, causes, and spatial and temporal patterns of forest harvest on private tracts throughout the central Cascade Mountain area, we relied on a new generation of annual land-use/land-cover (LULC) products created from the application of the Continuous Change De

Hawaii Land Cover and Habitat Status

These two raster data layers depict the land cover and degree of human disturbance to plant communities on the seven main Hawaiian Islands, and were developed as part of a comprehensive USGS assessment of carbon sequestration potential by natural ecosystems in the State of Hawaii.

Tsunami Travel Time Maps for Del Norte and Humboldt Counties, CA, reference year 2010

Tsunami travel time maps for Del Norte and Humboldt Counties in California in vector (shapefile) format for both slow and fast walking speeds and for bridges intact and bridges removed.

Forecasting tidal marsh elevation and habitat change through fusion of Earth observations and a process model

Regional models of tidal marsh elevation response to sea-level rise are needed to support coastal climate change adaptation decisions, including those related to land use planning, habitat management and infrastructure design. The Marsh Equilibrium Model (MEM) is a one-dimensional mechanistic elevation model that incorporates feedbacks of organic and inorganic inputs within the tidal frame to proj
