调研方向

首先检查地图渲染逻辑以及 public/fixtures/land_project_sites.geojson 中的 GeoJSON fixture，并将正确渲染的标记与损坏的标记进行比较。使用 Leaflet 和 React Leaflet 的参考资料检查坐标、圆形大小、图层叠放和缩放行为；当每个项目圆形都完整、居中且缩放一致，并且现有标签、交互和弹窗仍然正常工作时，即表示完成。

Description

Some land project circle markers are not rendering correctly on the ecosystem map view¹. As visible in the screenshot below, certain project markers display incomplete or incorrectly positioned circle overlays while other markers render normally².

This bug appears related to how GeoJSON project data is being consumed or rendered into map circle layers/markers³. The application currently uses a GeoJSON file to display land project sites on the map, and contributors should investigate whether the issue originates from malformed GeoJSON coordinates, radius calculations, map projection behavior, layer rendering order, or component styling⁴.

This is intended to be a relatively small bug-fix issue focused on correcting marker/circle rendering behavior while preserving the existing map interaction system¹.

Goals

  • Fix incorrectly rendered land project circle markers¹
  • Ensure all GeoJSON-based project markers render consistently²
  • Preserve existing map functionality and interactions³
  • Verify circles render at correct location and scale⁴
  • Prevent incomplete or clipped circle overlays¹

Implementation Instructions

  • Investigate current GeoJSON rendering logic²
  • Compare correctly rendered markers against broken markers³
  • Verify coordinate ordering and GeoJSON structure⁴
  • Check map layer rendering order and styling¹
  • Inspect radius calculation logic for circle overlays²
  • Ensure map projection/zoom scaling is handled consistently³
  • Verify markers render correctly at different zoom levels⁴
  • Preserve existing popup/label behavior¹
  • Please add comments/documentation if root cause is non-obvious²
  • Contributor may use browser devtools or map debugging utilities³

Expected Functionalities

Correct Circle Rendering
  • All land project markers render complete circle overlays⁴
  • Circles appear centered on intended project location¹
  • Marker visuals remain consistent across projects²
Stable Map Behavior
  • Existing labels/tooltips continue functioning³
  • Map interactions remain unaffected⁴
  • Rendering remains stable across zoom levels¹

Possible Investigation Areas

  • GeoJSON coordinate formatting²
  • Invalid geometry or polygon data³
  • Latitude/longitude ordering⁴
  • Circle radius scaling logic¹
  • Map library rendering edge cases²
  • Layer z-index or clipping behavior³
  • Projection inconsistencies⁴

Acceptance Criteria

  • All project circles render correctly¹
  • No incomplete or broken circle overlays remain²
  • GeoJSON markers appear at correct coordinates³
  • Existing map interactions still function⁴
  • Rendering works consistently across zoom levels¹
  • Fix does not introduce regressions to other markers²
