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.

Ogr split by attribute

This example splits a road shapefile into multiple new shapefiles based on unique values in a chosen attribute field. Using the OGR library from GDAL, it first iterates through all features to collect distinct attribute values from the specified field (e.g., "Type"). For each unique value, it creates a new shapefile via `CreateDataSource` and `CopyLayer`, then applies an attribute filter with `SetAttributeFilter` to identify and delete all features that do not match that value. The result is one separate shapefile per attribute category, demonstrating a straightforward spatial data partitioning workflow.

Gist f3b3c7d224f1701a9d7f

This Shiny application lets a user upload a CSV file of XY coordinates, which are then read with the built-in `read.table` function and converted into a spatial points object using `SpatialPointsDataFrame` from the `sp` package. The app renders a basic scatterplot of these points via `plot()` and offers a download button that exports the coordinates as an ESRI Shapefile using `writeOGR` from `rgdal`, zipping the resulting files for delivery. The interface is built with `bootstrapPage` and `fileInput`, and it validates that data has been selected before plotting.

Shiny / R : csv to shapefile

This Shiny/R application demonstrates a straightforward conversion of CSV point data into an interactive map and downloadable ESRI shapefile. Users upload a CSV file, which is read via `read.table` and converted into a spatial points data frame using `SpatialPointsDataFrame` from the `sp` package, with optional CRS assignment commented out. The coordinates are plotted using base R’s `plot` function, while the `writeOGR` function from `rgdal` exports the data as a shapefile, which is then zipped and served through a `downloadButton` wrapped in a `downloadHandler`.

Shp download

This example demonstrates a Shiny app feature that lets users download the current map view as a Shapefile and CSV. It shows how an interactive R-based mapping interface can package its underlying geographic data for external use. The code defines a `downloadHandler` that cleans up old temporary files, uses `writeOGR` from the `rgdal` library to create the Shapefile, writes a CSV with `write.csv`, and compresses everything into a ZIP archive with the `zip` function. The handler dynamically generates the download by referencing the `getGeoContent()` object, which contains both spatial and attribute data.

This example maps user-uploaded shapefiles by plotting their polygon boundaries in a main panel. It uses R’s `shiny` framework with `server.R` and `ui.R` files, relying on the `maptools` library’s `readShapePoly` function to load the spatial data. A reactive `uploadShpfile` expression handles file renaming and directory switching for multiple uploaded components, while `renderPlot` and `plotOutput` display the resulting map. The interface provides a sidebar `fileInput` for selecting shapefiles and a central plot area for visualization.

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.

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.

This visualization compares village codes from a JSON dataset against a Shapefile, showing which villages appear in one but not the other. It displays the mismatched codes in a text list, summarizing the total unique counts for each source (7,851 in JSON, 8,017 in Shapefile). The example uses a straightforward text rendering approach rather than graphical mapping, relying on file parsing and set operations to identify discrepancies. The data comes from GeoWill’s gist, with the output formatted as plain text lists for easy inspection.
