Summary & Purpose

This is a polygon data set representing the extent of urban development within areas of special interest in Boise, Idaho and the surrounding region. The data set was derived from Landsat data and the National Land Cover Database created by the Multi-Resolution Land Characteristics (MRLC) Consortium.

Data Attributes

We utilized the publicly available historical remote sensing data for five different years with a decadal interval: 1974, 1982, 1992, 2001 and 2011. We used Landsat derived land use and land cover maps developed by National Land Cover Database (NLCD) for the last three of the five study years: 1992, 2001 and 2011 (NLCD 2014). Since the focus of the study was urban growth, all the NLCD land cover classes were reclassified into two land classes: urban (developed) and non-urban (undeveloped). The NLCD 1992 dataset was made comparable directly with the data for the other two years by using 1992/2001 retrofit land cover change product as mentioned in Fry et al. (2009). For the years 1982 and 1974, for which NLCD maps are not available, a map of the study area with different land cover classes was delineated each using Landsat satellite images. We applied a supervised classification procedure using various ancillary data before reclassifying the maps into urban and non-urban land classes. The accuracy of delineated urban areas was improved to the maximum possible by geographically tallying the maps with high resolution orthophotos of the study site for respective years. The maps were then converted into vector data format so that patch-based spatial indices could be computed using Patch-Analyst (Rempel et al. 2012) and custom-created ArcGIS scripting tools. Projected Coordinate System: Albers Conical NAD_1983. Attribute definition: Area = Area of each patch/polygon.
