This example shows a failed attempt to crop a population raster to a polygon boundary using the GDAL command-line tool, invoked through Python’s `subprocess` module. The code constructs a list of arguments for `gdalwarp`, including the cutline shapefile, crop-to-cutline flag, output format `GTiff`, and input/output GeoTIFF paths, then calls it with `subprocess.call(argsSub, shell=True)`. The commented command line above indicates the intended successful shell operation, while the scripted version likely fails due to the misuse of `shell=True` with a list of arguments.

Using ogr2ogr from Scala

This example demonstrates how to invoke the GDAL `ogr2ogr` command-line utility directly from a Scala application to convert geographic data between formats. The code uses the `org.gdal.apps.ogr2ogr` class to execute conversions asynchronously via Scala’s `Future`, allowing non-blocking file processing. It shows two distinct conversions: one to ESRI Shapefile using default settings, and another to CSV with custom layer creation options (`-lco`) for geometry as WKT, automatic `.csvt` generation, and semicolon separators. The example reads from a GeoPackage input file and writes to organized subdirectories, demonstrating path handling with `java.nio.file.Paths` and directory creation via `Files.createDirectories`. Error handling is implemented through Scala’s `Try`-style success/failure callbacks.

Gist 745c7c03b5bf6b6f59d9

This example splits a single ESRI Shapefile into multiple new Shapefiles, one for each unique value found in a specified attribute field. It demonstrates how to use the OGR library from GDAL to read the original dataset, extract all distinct attribute values, and then create filtered copies. The process first enumerates unique values, then iterates through them to create new Shapefile layers, applies an SQL attribute filter to exclude features not matching the current value, and deletes the remaining unwanted features.

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.

Simple shell script to merge shapefiles from INE

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.

Simple script to crop pokemon card images

This example is a batch script that crops Pokémon card images into a uniform size and applies a rounded-corner mask. It processes image files by dragging them onto the script or running it in a folder, writing cropped PNGs to an output directory. The script uses ImageMagick’s `magick` command-line tool to perform image identification, cropping, and compositing, specifically leveraging the `identify` operation for dimensions and `convert`-style options for the mask overlay. It also includes a fallback to install ImageMagick via Windows Package Manager (`winget`) if not found.

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.

Gist 0c701eddfaa4b93ee172

Two terminal sessions show failed attempts to import OpenStreetMap data into a PostgreSQL database using Osmosis, a Java command-line tool. The visualization captures log output from sequential runs of the `osmosis` command, displaying errors from Java's `java.net.ConnectException` when the database connection is refused. The first attempt fails because the `--truncate-pgsql` task receives an unexpected `port` argument, while the second fails because PostgreSQL is not running. The display highlights the pipeline's reliance on database configuration and connection handling, rendered as plain terminal text.

Stats zonales

This example uses QGIS’s `QgsZonalStatistics` API to compute zonal statistics from a population raster (`popgrid.tif`) over vector polygons representing urban morphological zones (`UMZ_2000.shp`). It loads the vector layer via `QgsVectorLayer`, prompts the user for confirmation, then runs the calculation with a `ZS_` prefix for new attribute columns. The script prints the layer’s name, feature count, geometry type, and EPSG code before timing the operation, demonstrating a straightforward batch workflow for enriching polygon attributes with raster data.
