The crucial step is projecting geographic coordinates (degrees) into a projected coordinate system (meters).\n\n## Prerequisites\n\n```bash\npip install geopandas shapely\n```\n\n## Basic Usage\n\nWhen calculating distances on the Earth's surface, you **must not** calculate distance directly in `EPSG:4326` (which uses degrees). Instead, you project the data into a metric coordinate system like `EPSG:4087` (World Equidistant Cylindrical) or `EPSG:3857` (Web Mercator, though it distorts distance). `EPSG:4087` or `EPSG:6933` (Cylindrical Equal Area) are common for global calculations, or a local UTM zone. `EPSG:4087` provides distances in meters.\n\n```python\nimport geopandas as gpd\nfrom shapely.geometry import Point\n\n# 1. Load data\npoints_gdf = gpd.read_file('points.geojson')\nlines_gdf = gpd.read_file('lines.geojson')\n\n# 2. Define a metric CRS (e.g., EPSG:4087 for World Equidistant Cylindrical)\nMETRIC_CRS = \"EPSG:4087\"\n\n# 3. Project both datasets to the metric CRS\npoints_proj = points_gdf.to_crs(METRIC_CRS)\nlines_proj = lines_gdf.to_crs(METRIC_CRS)\n\n# 4. Optional: If you want distance to any part of the lines network, combine them\nnetwork_geometry = lines_proj.geometry.unary_union\n\n# 5. Calculate distance (the result will be in meters because of the CRS)\npoints_gdf['distance_m'] = points_proj.geometry.distance(network_geometry)\n\n# 6. Convert to kilometers\npoints_gdf['distance_km'] = points_gdf['distance_m'] \u002F 1000.0\n\n# 7. Find the point furthest away\nfurthest_point = points_gdf.nlargest(1, 'distance_km').iloc[0]\n\nprint(f\"Furthest point distance: {furthest_point['distance_km']:.2f} km\")\n```\n\n## Tips\n- Always verify your metric CRS when doing distance calculations. `EPSG:4326` will return distances in degrees.\n- Combining features with `.unary_union` before calling `.distance()` is significantly faster than calculating distances to each feature individually.\n","# Distance Calculation with GeoPandas\n\nThis skill demonstrates how to calculate the distance between geographic features (like points and lines) accurately.
