🗂️ Geopackage Reader

The Geopackage (GPKG) reader allows you to upload geopackage files into Geoflip. Geopckages are based on sqlite databases and can support multiple types of geometry within the single gpkg file and are a very convenient way to store spatial data.

📜 Format Details​

  • File type: .gpkg the geopackage file.
  • **Upload type: send the gpkg`` as input_file` in a multipart form.
  • CRS handling:
    • Geoflip reads the CRS from the .gpkg file directly.
    • If crs is missing or invalid in the geopackage file, reprojection may fail.

⚙️ Example Config​

{
  "input": {
    "format": "gpkg"
  },
  "transformations": [
    { "type": "union" }
  ],
  "output": {
    "format": "shp",
    "epsg": 3857
  }
}

📑 Example API Call​

First make sure you have a valid geopackage file (.gpkg) then send to the API:

curl -X POST https://api.geoflip.io/transform \
  -F 'config={
    "input":{"format":"gpkg"},
    "transformations":[{"type":"union"}],
    "output":{"format":"shp","epsg":3857}
  }' \
  -F "input_file=@/tmp/parcels.gpkg;type=application/geoopackage+sqlite"

Response

{ "job_id": "abcd-ef01-2345-6789" }

Poll for status:

curl https://api.geoflip.io/result/status/abcd-ef01-2345-6789

And download from the output_url when status is SUCCESS.

✅ Notes​

  • CRS reprojection is applied at the output stage, based on output.epsg.
  • Geopackages are a great way to store multiple geometry types in a single tidy file.
