Geospatial Analysis with GeoPandas (Improved)
Key Concepts
- Coordinate Systems: EPSG:4326 for storage, EPSG:4087 (metric) for distance.
- Modern API: As of GeoPandas 1.0+, use
unary_union(orunion_all()for newer versions) to combine geometries. - Data Conversion: When using raw GeoJSON, extract
propertiesandgeometry.coordinatesmanually before GeoDataFrame creation.
Updated Pattern
import geopandas as gpd
from shapely.geometry import Point
# 1. Load data
# 2. Extract components if necessary
# 3. Project to metric CRS
METRIC_CRS = "EPSG:4087"
points_proj = gdf.to_crs(METRIC_CRS)
# 4. Combine geometries using .union_all()
boundary_geom = boundary_gdf.to_crs(METRIC_CRS).geometry.union_all()
# 5. Calculate distance
gdf["dist"] = points_proj.geometry.distance(boundary_geom)

travel-planning-workflow
Invoke this skill when performing travel planning. It defines a structured workflow for generating itineraries. Following this workflow is essential to ensure the final plan satisfies user requirements.
bundled-dataset-search-tool
invoke this skill when you need to perform database search for travel planning. This skill provides some useful pre-packaged tools to look up accommodations, attractions, cities, driving distance, flights, and restaurants from the bundled dataset.
glm-output
Output-processing guidance for GLM tasks. Especially useful after glm-basics and glm-calibration when you need verifier-matching metrics from output.nc and a final /root/metrics.json.
glm-calibration
Calibration guidance for GLM tasks. Often most effective after glm-basics has clarified the setup; glm-output is the companion skill for exact final metric computation.
glm-basics
A good starting point for GLM calibration tasks. Use to inspect glm3.nml, confirm how GLM runs, and identify the relevant files before moving on to calibration and output evaluation.
