Estimate the relationship between Internet use and geospatial big data at the lowest geographic level with actual data from household surveys or censuses, e.g. municipality.<br>2. Apply the statistical model and predict Internet use for even smaller geographical areas, e.g. postal codes, enumeration areas or standardized tiles.<br>3.
