Geolink R package - Christopher Lloyd

GeoLink is an R package that assists users with merging publicly available geospatial indicators with georeferenced survey data. The georeferenced survey data can contain either latitude and longitude geocoordinates, or an administrative identifier with a corresponding shapefile. The procedure involves: Downloading geospatial indicator data, Shapefile tessellation, Computing Zonal statistics, and spatial joining of geospatial data with unit level data. The package, for example, can be used to link household characteristics measured in surveys with satellite-derived measures such as the average radiance of night-time light. The package can also calculate indicator values for each pixel covered by a tessellated grid in which a household is located. Finally, the package can be used to calculate zonal statistics for a user-defined shapefile (at native resolution or tessellated) and link the results to survey data. GeoLink complements the povmap and EMDI R packages to facilitate small area estimation with geospatial indicators. The latter two packages enable the estimation of regionally disaggregated indicators using small area estimation methods and includes tools for processing, assessing, and presenting the results. #rstats
