Argo Tasks

Utility tasks containers for argo

Why?

LINZ uses Argo workflows for running bulk data tasks in AWS, there are some utilities that are often needed for these tasks

Command Line Tools

Commands and their usage

`lds-fetch-layer`

Fetch a layer from the LDS and download it as GeoPackage.

Example

Fetch the latest version of layer 50063 - 50063-nz-chatham-island-airport-polygons-topo-150k and save it into ./output:

lds-fetch-layer --target ./output 50063

Multiple layers can be fetched at the same time, fetch 51002 and 51000:

lds-fetch-layer  --target ./output 51002 51000

`generate-path`

Generate target path for ODR buckets using collection metadata.

The date can be omitted from the survey name (example: s3://nz-elevation/new-zealand/new-zealand/dem_1m/2193/) by passing the --no-date-in-survey-path flag.

For imagery naming conventions see: https://github.com/linz/imagery/blob/master/docs/naming.md For elevation naming conventions see: https://github.com/linz/elevation/blob/master/docs/naming.md

Example

generate-path --target-bucket-name nz-imagery s3://linz-workflows-scratch/2024-01/04-is-niwe-hawkes-bay-l7tt4/flat/

`list`

List files from AWS and split them into groups for processing.

Example

List all tiffs in a folder:

list s3://linz-imagery/sample --include ".*.tiff$" --output /tmp/list.json

List tiffs and split them into groups of 10:

list s3://linz-imagery/sample --include ".*.tiff$" --group 10  --output /tmp/list.json

List tiffs and split them into groups of either 10 files or 100MB which ever comes first:

list s3://linz-imagery/sample --include ".*.tiff$" --group 10 --group-size 100MB --output /tmp/list.json

Exclude a specific tiff:

list s3://linz-imagery/sample --include ".*.tiff$"  --exclude "BG33.tiff$" --output /tmp/list.json

`pretty-print`

Format all JSON files within a directory using prettier.

Example

Format and overwrite files:

pretty-print source/

Create a copy of the formatted file in another flatten directory (testing only - does not handle duplicate filenames):

pretty-print source/ --target output/

`create-manifest`

Generate a manifest of files that need to be copied and their target paths.

If $ACTION_PATH is set, store the resulting manifest files as json documents.

Example

create-manifest s3://link-workflow-artifacts/sample/flat --include ".*.tiff$"  --exclude "BG33.tiff$" --output /tmp/list.json --target s3://linz-imagery/sample

`copy`

Copy the files in the manifest between two locations. For manifest creation see create-manifest.

Only copy files which have changed when using the --no-clobber (or --force-no-clobber) option.

Always copy files even if they have changed when using the --force option.

Example

copy ./debug/manifest-eMxkhansySrfQt79rIbAGOGrQ2ne-h4GdLXkbA3O6mo.json --concurrency 10

`group`

group an input list into an array of arrays.

Example

group --size 2 "a" "b" "c" '["1","2","3"]'
# [["a","b"], ["c","1"], ["2", "3"]]

`stac catalog`

Create STAC catalog JSON file when given links to catalog template JSON file and location to search for collection.json files.

Example

stac catalog --template catalog_template.json --output catalog.json /path/to/stac/

Example template file:

{
  "stac_version": "1.0.0",
  "type": "Catalog",
  "id": "linz-imagery",
  "description": "Toitū Te Whenua Land Information New Zealand makes New Zealand's publicly owned aerial and satellite imagery archive freely available to use under an open licence. This public S3 bucket has been made available to enable bulk access and cloud-based data processing. You can also access the imagery through the LINZ Data Service or LINZ Basemaps.",
  "links": [
    { "rel": "self", "href": "https://linz-imagery.s3.ap-southeast-2.amazonaws.com/catalog.json" },
    { "rel": "root", "href": "./catalog.json" }
  ]
}

Output will look like:

{
  "stac_version": "1.0.0",
  "type": "Catalog",
  "id": "linz-imagery",
  "description": "Toitū Te Whenua Land Information New Zealand makes New Zealand's publicly owned aerial and satellite imagery archive freely available to use under an open licence. This public S3 bucket has been made available to enable bulk access and cloud-based data processing. You can also access the imagery through the LINZ Data Service or LINZ Basemaps.",
  "links": [
    {
      "rel": "self",
      "href": "https://linz-imagery.s3.ap-southeast-2.amazonaws.com/catalog.json"
    },
    {
      "rel": "root",
      "href": "./catalog.json"
    },
    {
      "rel": "child",
      "href": "./auckland/auckland_2010-2011_0.125m/rgb/2193/collection.json",
      "title": "Auckland 0.125m Urban Aerial Photos (2010-2011)",
      "file:checksum": "1220670da4eb9d1e9a8ce209ac2894bc523ffc33d805718058ff268d20092f3596fd",
      "file:size": 387938
    },
    {
      "rel": "child",
      "href": "./auckland/auckland_2010-2012_0.5m/rgb/2193/collection.json",
      "title": "Auckland 0.5m Rural Aerial Photos (2010-2012)",
      "file:checksum": "1220fd8793f08d92ca52ebf283db98c847cf2a23730ff10e8da95121bbd753445068",
      "file:size": 23987
    }
  ]
}

`stac github-import`

Format and push a STAC collection.json file and Argo Workflows parameters file to a GitHub repository. Used by the publish-copy Argo Workflow.

Synopsis

stac github-import --source=SOURCE_S3_URL --target=TARGET_S3_URL [--repo-name=OWNER/REPO] [--ticket=TICKET_REFERENCE] [--copy-option=COPY_OPTION]

OWNER/REPO defaults to "linz/imagery".
TICKET_REFERENCE is a Jira ticket ID.
COPY_OPTION can contain a flag for the TIFF and STAC items copy job. Defaults to "--no-clobber".

Example

stac github-import --source=s3://linz-workflows-scratch/2024-03/13-is-niwe-hawkes-bay-all-blocks-xfcxl/flat/ --target=s3://nz-imagery/hawkes-bay/hawkes-bay_2023-2024_0.25m/rgb/2193/ --repo-name=linz/imagery-test --ticket=AIP-56 --copy-option=--force

`stac validate`

Validate STAC file(s) from an S3 location

Example

Validate a single item:

stac validate s3://linz-imagery-staging/test/stac-validate/item1.json

Validate multiple items:

stac validate s3://linz-imagery-staging/test/stac-validate/item1.json s3://linz-imagery/test/test/item2.json

Validate a collection and linked items:

stac validate --recursive s3://linz-imagery-staging/test/stac-validate/collection.json

Validate a collection without validating linked items:

stac validate s3://linz-imagery-staging/test/stac-validate/collection.json

Validate a the file:checksum of all assets inside of a collection:

stac validate --checksum-assets --recursive s3://linz-imagery-staging/test/stac-validate/collection.json

Validate the file:checksum of all STAC links inside of a collection:

stac validate --checksum-links --recursive s3://linz-imagery-staging/test/stac-validate/collection.json

Validate the file:checksum of all assets and STAC links inside of a collection:

stac validate --checksum-assets --checksum-links --recursive s3://linz-imagery-staging/test/stac-validate/collection.json

`tileindex-validate`

Validate or create retiling information for a list of tiffs.

Outputs files for visualisation of the tiles and as an list for topo-imagery to use for retiling with GDAL.

input.geojson GeoJSON file containing the bounding boxes of the source files. Example: input.geojson
output.geojson GeoJSON file containing the bounding boxes of the requested target files. Example: output.geojson
file-list.json a list of source and target files to be used as an input for topo-imagery. Example: file-list.json

--validate Validate list of tiffs match a LINZ map sheet tile index and assert that there will be no duplicates. Example:

tileindex-validate --validate --scale 5000 s3://linz-imagery/auckland/auckland_2010-2012_0.5m/rgb/2193/

--retile Output a list of tiles to be retiled to the scale specified, and which tilename they should receive when merged. Example:

tileindex-validate --retile --scale 10000 s3://linz-imagery/auckland/auckland_2010-2012_0.5m/rgb/2193/

`bm-create-pr`

Fetch a layer from the LDS and download it as GeoPackage.

Example

Create a pull request in the basemaps-config repo after imagery layer imported:

bm-create-pr --target
["s3://linz-basemaps/3857/gisborne-cyclone-gabrielle_2023_0.2m/01HAAYW5NXJMRMBZBHFPCNY71J/","s3://linz-basemaps/2193/gisborne-cyclone-gabrielle_2023_0.2m/01HAAYW5PMJ90MGRSQCB9YPX0W/"]

Add --individual flag to import layer into standalone individual config file, otherwise import into aerial map. Add --vector flag to import new layer into vector map.

Versioning and Release

To publish a release, the Pull Request opened by release-please bot needs to be merged:

Open the PR and verify that the CHANGELOG contains what you expect in the release. If the latest change you expect is not there, double-check that a GitHub Actions is not currently running or failed.
Approve and merge the PR.
Once the Pull Request is merged to master a GitHub Action it creates the release and publish a new container tagged for this release.
