geopandas SKILL.md skillA
geopandas from marielynneblock/arcanum-artifex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add marielynneblock/arcanum-artifex/geopandas@git:20260710.0115f49Pins git:20260710.0115f49 in mdr.lock. Pin the fingerprint instead.

Python library for working with geospatial vector data including shapefiles, GeoJSON, and GeoPackage files. Use when working with geographic data for spatial analysis, geometric operations, coordinate transformations, spatial joins, overlay operations, choropleth mapping, or any task involving reading/writing/analysing vector geographic data. Supports PostGIS databases, interactive maps, and integration with matplotlib/folium/cartopy. Use for tasks like buffer analysis, spatial joins between…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GeoPandas
GeoPandas extends pandas to enable spatial operations on geometric types. It combines the capabilities of pandas and shapely for geospatial data analysis.
## Installation
```bash
uv pip install geopandas
```
### Optional Dependencies
```bash
# For interactive maps
uv pip install folium
# For classification schemes in mapping
uv pip install mapclassify
# For faster I/O operations (2-4x speedup)
uv pip install pyarrow
# For PostGIS database support
uv pip install psycopg2
uv pip install geoalchemy2
# For basemaps
uv pip install contextily
# For cartographic projections
uv pip install cartopy
```
## Quick Start
```python
import geopandas as gpd
# Read spatial data
gdf = gpd.read_file("data.geojson")
# Basic exploration
print(gdf.head())
print(gdf.crs)
print(gdf.geometry.geom_type)
# Simple plot
gdf.plot()
# Reproject to different CRS
gdf_projected = gdf.to_crs("EPSG:3857")
# Calculate area (use projected CRS for accuracy)
gdf_projected['area'] = gdf_projected.geometry.area
# Save to file
gdf.to_file("output.gpkg")
```

How to install
mdr add marielynneblock/arcanum-artifex/geopandas@sha256:02c51dd4289a63b8The line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
