Convert the data files (HydroLAKES) to GeoJSON and upload it to the repo

Issue created with ChatGPT models' help¹

---

Description

Add HydroLAKES data into the repository by converting the provided source files (Shapefile, File Geodatabase, or similar GIS formats) into valid GeoJSON format¹.

The converted GeoJSON file should then be uploaded into the repository fixtures folder so the map can automatically consume and render the dataset².

This issue is intentionally kept small and beginner-friendly for first-time contributors³.

---

Goals

• Convert HydroLAKES dataset into GeoJSON¹
• Use standard GIS conversion workflows/tools²
• Upload converted GeoJSON file into repo fixtures folder³
• Ensure GeoJSON renders correctly on the map⁴
• Keep implementation lightweight and beginner-friendly¹

---

Implementation Instructions

• Download the HydroLAKES shapefile OR geodatabase dataset¹

• Convert the dataset from:

  • Shapefile (.shp)²
  • File Geodatabase (.gdb)³
  • or other provided GIS formats⁴

  into valid .geojson format¹

• Contributors may use standard GIS tools/workflows such as:

  • GDAL/OGR²
  • QGIS³
  • online conversion tools⁴

• Name the GeoJSON file "Major Lakes (North America)"

• Upload the final GeoJSON file to:

public/fixtures/

Repo path:²

https://github.com/OpenSourceFellows/map_dashboard_hackathon/tree/main/public/fixtures

• Verify the GeoJSON structure is valid and loads correctly on the map³
• Keep the dataset limited to North America only⁴

---

Expected Functionalities

GeoJSON Conversion

• Source GIS data converts successfully into valid GeoJSON¹
• Geometry and properties remain intact after conversion²

Repository Integration

• GeoJSON file is uploaded into fixtures folder³
• Existing map setup can automatically consume the file⁴

---

Notes

• Contributors may use their own judgment regarding conversion workflow/tools¹
• Standard GIS conversion procedures from documentation/tutorials are acceptable²
• Keep PR scope small and focused only on dataset conversion/upload³
• No frontend UI work is required for this issue⁴
• Name the GeoJSON file "HydroLAKES"

---

Acceptance Criteria

• HydroLAKES dataset converted to valid GeoJSON¹
• GeoJSON file uploaded into public/fixtures/²
• Name the GeoJSON file "HydroLAKES"
• File structure is valid and readable³
• Dataset loads correctly into existing map setup⁴
• PR scope remains small and beginner-friendly¹

² QGIS Documentation
³ map_dashboard_hackathon fixtures folder
⁴ GeoJSON Specification

Inspect public/fixtures/ and the existing map setup first to confirm how fixture files are consumed. Convert the North America HydroLAKES source with GDAL/OGR or QGIS, validate the resulting GeoJSON structure, and upload it as HydroLAKES. Done means the file is in public/fixtures/ and loads correctly on the map without frontend changes.
