Summary

This dataset contains a raster-based landcover map for Midway Atoll as of Jan 14, 2010. Landcover is classified into 9 different categories including various types of vegetation, bare ground, beach, and human structures. These categories were created using manual digitizing and unsupervised classification techniques on a DigitalGlobe WorldView-2 satellite image taken January 14, 2010.

Purpose

These data were collected as part of a large research project that examined the impacts of climate change, sea-level rise, storm waves, and tsunamis on avifauna and their habitat in the Northwestern Hawaiian Islands. Collected data included a wide range of physical data (coastlines, digital elevation models, bathymetry, predicted wave run-up from storm waves, tsunami high water marks), habitat data (land cover classifications, vegetation maps and monitoring plots), and biological survey data (bird abundance and density, nest census, and habitat surveys). Ultimately the purpose of developing this landcover dataset was to help estimate the quantity of nesting habitat that was inundated in the March 11, 2011 tsunami event. In particular, this landcover dataset was used as a proxy of nesting distribution for species that did not have nest distribution surveys or maps available.
