调研方向
首先检查 public/fixtures 中现有的文件和现有的地图设置，然后查阅 HydroSHEDS HydroBASINS 产品文档。这个 epic 应在开始工作前拆分为按 level 划分的 issue；完成意味着 North America 的每个 level 都在 public/fixtures 中具有有效且可读的 GeoJSON，并且能够正确渲染。

描述
Epic issue created with ChatGPT models' help
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
.geojsonformat -
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
