New Digital Roads Data Set Characterizes Intercity Road Networks Around the World
CIESIN has released a digital global data set on intercity roads, the Global Roads Open Access Data Set, Version 1 (gROADSv1). Developed under the auspices of the Global Roads Data Development Task Group of the Committee on Data for Science and Technology (CODATA) of the International Council for Science, gROADSv1 combines the best available open access data on roads between human settlements into a global roads coverage consistent with the United Nations Spatial Data Infrastructure Transport (UNSDI-T) version 2 data model.
This first version of the gROADS data set is part of a continuing effort to address the need among professionals in the humanitarian response, development, transportation, biodiversity conservation, and allied fields for free and open, spatially accurate, and readily updateable data on roads in order to better understand issues such as market access, cost of transportation, and human pressures on the environment. Data on road networks connecting human settlements may be especially valuable when used in conjunction with remote sensing and other spatial data to improve decision making related to urbanization and rural development. gROADSv1 is being distributed by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN, and represents an important step towards addressing the criteria established by the CODATA Task Group.
