The objective in the exercise is to determine how many public computers are available per person as a result of spatial distribution of libraries and people.
Part 1: Grid of points
Using Brooklyn, NY boundary, create a grid of points spaced at 250’. Please report the number of grid points resulting.
Part 2: “Smooth” population on a uniform grid of points
Using Brooklyn, NY boundary, census block population data (US Census 2000) and the resulting grid of points from Part 1, construct a “smoothed” population density for Brooklyn. Using Spatial Analyst create a population raster from census blocks. Note the default density and make sure it corresponds to the 250’ grid point. Apply the population raster to the vector grid making sure that the resulting total population is equivalent to original data. Please show results and document steps in detail.
Part 3 : Determining Library computers per population
Using Brooklyn , NY boundary, uniform population grid resulting from Part 2 and the attached table, determine the interpolated density of publicly available computers from Brooklyn’s Public Library System per population (using the uniform grid of points population). Please show results and document steps in detail.
