Description

popbioko: Computes Bioko island population metrics.

Retrieve data

Gets data from the web or from cluster storage.

• data_configuration - Reads configuration file on where to download data.

• un7zip - Unzip a 7zip file.

• get_from_ihme - Use scp to retrieve data.

• download_worldpop - Retrieve worldpop data.

• download_bioko_grids - Retrieve Bioko grid data.

• download_hrsl_points - Download HRSL from the repository.

Read and write data

Reads the data into R or writes it to a file or finds it on disk.

• read_bioko_grids - Read the Bioko grid information as a shapefile.

• read_hrsl - Read the HRSL as a raster file.

• read_landscan - Load LandScan raster file.

• write_aligned_raster - Write a raster layer to a file.

• filenames_to_description - Given filenames, decode them into traits of the file.

• read_bimep_point_data - Read BIMEP point data

• bimep_population_as_points - Turns each population entry into a lat-long coordinate.

Conversions

• im_to_raster - Convert a spatstat im to a raster image

• parameters_of_km_grid - Given a 1km grid for Bioko, figure out how you would remake it.

• make_fresh_grid - Creates a regular grid of rectangular polygons.

• bimep_named_vector - Associate BIMEP index with its map ID.

• bimep_on_grid - Aligns long-lat per-house data to a given raster grid.

• bimep_population_as_raster - Read BIMEP population as a raster.

• hrsl_points - Given an HRSL raster, convert it into points in space.

• assign_to_grid - Given spatial points of population, assign them to shapes.

Metrics

• population_count_estimator - Estimate density of population using density estimator on points.

• population_density_estimator - Estimate density of population using density estimator on the image.

• density_from_disc - Find the average density within a 1 square km disc around each pixel

• square_meters_per_pixel.im - Calculate square meters per pixel for a spatstat im

• square_meters_per_pixel.raster - Calculate square meters per pixel for a raster::raster

• pareto_fraction - Compute pareto fraction of a vector.

• power_bandwidth - Estimate bandwidth for a density function kernel with Bowman and Azzalini.

• density_estimated - Create a map with density estimation

• urban_fraction_population - Urban fraction from a population raster

• urban_fraction_density - Urban fraction from a density raster

• urban_fraction_by_density_estimator - Calculate urban fraction using a density estimator

• summary_statistics - Compute basic summary statistics.

Jittered Grid

These functions calculate summary statistics for the gold standard data for a set of grids that are slightly shifted, so that we can get a sense of error due to the exact placement of the grid.

• summary_statistics_multiple_grids - Script to compute summary statistics with uncertainty from alignment of grid.

• clean_grid - Given an input grid, crop it to the admin unit and give us a few pixels of border.

• summarize_shifted_alignment - Compute summary statistics for geolocated data aligned to a grid.

• summarize_over_shifts - Loops over the given grid shifts and runs the summarizer on each shift.
