Criteria maps/ raster of Spatial Socioeconomic Impact Assessment as used in the paper: "Banerjee, P., & Ghose, M. K. (2017). A geographic information system-based socioeconomic impact assessment of the broadening of national highway in Sikkim Himalayas: a case study. Environment, Development and Sustainability, 19(6), 2333–2354. https://doi.org/10.1007/s10668-016-9859-7. "

Socioeconomic criteria raster maps of spatial impact assessment of highway broadening in Sikkim Himalaya. The maps were generated by GPS tagged responses of participants from the project affected population in a buffer area of 2 km radius from the highway. A structured questionnaire was administered to the participants and their residential location was tabulated using GPS handset. The responses of 100 respondents were aggregated into several townships along the highway using k-nearest neighbor mean calculation. The database was projected in the ArcGIS environment and Empirical Bayesian Kriging was used to prepare the rasters.
