Title: Future Road Density
Abstract: Road density is generally highly correlated with amount of developed land cover. High road densities usually indicate high levels of ecological disturbance. More information about these resources, including the variables used in this study, may be found here: https://edg.epa.gov/data/Public/ORD/NERL/ReVA/ReVA_Data.zip.
Purpose: The data can be used for analysis and general mapping. Information provided in these data tables is indexed to HUC Code, and can be joined to the HUC_CODE field of the HUC250K layer. It was developed for use in EPA's Regional Vulnerability Assessment (ReVA) program. The ReVA program is designed to produce the methods needed to understand a region's environmental quality and its spatial pattern. The objective is to assist decision makers in making more informed decisions and in estimating the large-scale changes that might result from their actions.
