This example shows a shell script that downloads, reprojects, and merges Mexican electoral geography shapefiles from the INE’s distritación 2017 federal collection into a single output file. It processes layers such as `SECCION`, `ENTIDAD`, and `DISTRITO` for all 32 states, using `ogr2ogr` from GDAL to reproject each source into EPSG:4326 and append the features. The script handles a structural anomaly for file number 06 by adjusting the source path, and it relies on `/vsizip//vsicurl/` for remote zip access. The merged result is saved as a new shapefile named with the layer and `-wgs84` suffix.

Scripts to merge local electoral districts in Mexico

This example shows a shell script that merges 32 individual shapefiles of Mexico’s local electoral districts into a single national layer. The script uses GDAL’s `ogr2ogr` command-line utility, with two variants: one that reprojects each source file to EPSG:4326 (WGS84) during the merge, and another that preserves the original projection. It reads the shapefiles directly from zipped remote archives via the `/vsizip//vsicurl/` virtual file system, downloading each state’s `DISTRITO_LOCAL.shp` from the IFE cartography server. The first execution creates the output file, while subsequent iterations append data to it, building the combined dataset.

Shell script to import data into Postgres from https://www.nhgis.org. If you use this, you'll need to edit line 14 to include the census data you're importing.

This script sets up a Postgres database to hold U.S. Census block-group data, combining demographic race counts with spatial geometries. It first imports CSV race data into a table, then converts shapefiles to a uniform projection (EPSG:4326) using `ogr2ogr` and appends them via `shp2pgsql`. The code uses PostGIS for geometry support and creates a spatial index on the `geom` column. It relies on command-line tools like `dropdb`, `createdb`, and `psql`, processing files from the NHGIS source archive. The final output enables querying joined attribute and spatial data.

This example visualizes the spatial relationships between metropolitan statistical areas and their constituent counties, townships, and other administrative geometries. The code first builds a combined geometry table using SQL, merging overlapping regions across multiple spatial layers while excluding special cases like Boston. It then renders these shapes using D3.js, likely leveraging `d3.geoPath` for projection and canvas or SVG drawing. The query explicitly handles hierarchical and overlapping geographies, prioritizing township-level detail where available and falling back to county unions for other areas. The final visualization shows how different government boundaries interlock within U.S. metropolitan regions, with the SQL preprocessing ensuring no duplicated or missing polygons.

Merging Counties II

This example displays a single gray landmass of the United States by merging all county geometries into one unified shape. The visualization uses TopoJSON and D3’s `d3.geo.albersUsa` projection with `d3.geo.path` to render the merged polygon. The code loads county data from a remote `us.json` file and applies `topojson.merge` to combine the geometries before drawing the SVG path. The result is a simplified state boundary map without individual county outlines.

Municipalities of Mexico II

This example displays a map of Mexico with two layered vector paths: municipalities rendered with thin strokes and states overlaid with thicker outlines. It uses a TopoJSON file that was preprocessed from INEGI shapefiles using command-line tools and visualizes the data with D3’s `d3.geoMercator` projection and `d3.geoPath`. The map is drawn as SVG, with the paths selected and bound to the TopoJSON features via `topojson.feature` and `d3.json`.

This visualization shows the intersection of Oregon’s boundary with a grid of elevation-derived polygons, highlighting where the two geospatial datasets overlap. It uses `ndjson-join` to combine GeoJSON features from `oregon.json` and the `ned_1arcsec_g.shp` shapefile, then filters the pairs with `ndjson-filter` and the JSTS library’s `intersection` method to retain only non-empty geometric overlaps. The final `ndjson-map` extracts the matching features, revealing the spatial alignment between the state outline and the elevation grid cells. The code relies on command-line geospatial tools and JSTS for geometry operations.

This example demonstrates a spatial correction of a U.S. District Court jurisdiction boundary using PostGIS. It shows how an erroneous polygon (fid 57) is split into two parts, with one part merged into a neighboring jurisdiction (fid 58) and the other retained in place. The SQL uses `st_dump` to extract the polygon components, then `st_union` and `st_multi` to recompute the merged and retained geometries. The `UPDATE` statement with a `CASE` expression applies the corrected shapes back to the table, relying on PostGIS geometry functions for the operation.

Merging States

This example demonstrates merging multiple US state polygons into a single shape while removing interior borders, using `topojson.merge` on a filtered set of state geometries. A static map renders all states in gray with white boundary strokes via `d3.geo.path` and an AlbersUSA projection, while selected states appear filled in orange with a black outline. It uses D3 v3 and TopoJSON v1, loading geographic data from a local `us.json` file, and highlights the merged path by filtering geometries against a predefined set of state IDs.
