調査の方向性

まず public/fixtures 内の既存ファイルと既存の map setup を確認し、その後 HydroSHEDS HydroBASINS product documentation を参照してください。この epic は作業開始前にレベル別の issue に分割する必要があります。完了条件は、North America の各レベルに有効で読み取り可能な GeoJSON が public/fixtures にあり、正しくレンダリングされることです。

Description

Add HydroBASINS North America polygon datasets for Levels 2 through 12 into the repository by converting the provided HydroBASINS GIS datasets into valid GeoJSON format.

HydroBASINS contains hierarchical watershed polygon datasets across multiple levels of granularity. This epic tracks the work required to convert and upload each North America polygon level dataset individually into the repository fixtures folder.

To keep contributions small and beginner-friendly, each HydroBASINS level should be handled in its own separate issue and pull request.

The converted GeoJSON files will allow the existing map setup to consume and render HydroBASINS polygon layers directly from static fixture data.


Goals

  • Track HydroBASINS North America polygon conversion work for Levels 2–12
  • Keep each level isolated into its own small beginner-friendly issue
  • Convert all targeted GIS datasets into valid GeoJSON format
  • Upload GeoJSON files into the repository fixtures folder
  • Ensure datasets remain readable and render correctly in the existing map setup

Scope

This epic covers the following HydroBASINS North America polygon levels:

  • Level 2
  • Level 3
  • Level 4
  • Level 5
  • Level 6
  • Level 7
  • Level 8
  • Level 9
  • Level 10
  • Level 11
  • Level 12

Each level should have:

  • Its own GitHub issue
  • Its own GeoJSON conversion task
  • Its own lightweight PR

Implementation Instructions

  • Download the HydroBASINS North America datasets from the official HydroSHEDS source

  • Each subissue should focus only on a single HydroBASINS level

  • Convert GIS datasets into valid .geojson format

  • Contributors may use standard GIS conversion workflows/tools including:

    • GDAL/OGR
    • QGIS
    • Mapshaper
    • MyGeoData
    • Geoutil
    • or similar lightweight GIS conversion workflows
  • Upload converted files into:

public/fixtures/

Repo path:

https://github.com/OpenSourceFellows/map_dashboard_hackathon/tree/main/public/fixtures
  • Verify GeoJSON validity before submitting PRs
  • Verify datasets render correctly in the existing map setup

Optional lightweight cleanup improvements:

  • Remove unnecessary properties
  • Reduce file size if datasets become extremely large
  • Preserve polygon geometry accuracy during conversion

Expected Functionalities

GeoJSON Dataset Conversion
  • Each HydroBASINS polygon dataset converts successfully into valid GeoJSON
  • Polygon geometry and important attributes remain intact after conversion
Repository Integration
  • GeoJSON files are uploaded into the fixtures folder
  • Existing map setup can load and render the datasets correctly

Notes

  • This epic is intended for hackathon-friendly contributions
  • Each HydroBASINS level should remain a separate issue for easier onboarding and review
  • Contributors do not need frontend UI changes
  • Contributors only need to focus on dataset conversion/upload tasks
  • Static GeoJSON fixtures are acceptable for this phase of development

Acceptance Criteria

  • Separate issues created for HydroBASINS Levels 2–12
  • GeoJSON datasets uploaded into public/fixtures/
  • GeoJSON structures are valid and readable
  • Datasets render correctly in the existing map setup
  • PRs remain small and beginner-friendly
  • All datasets remain limited to North America only
