GeoPandas – Overview of Basic Tools

Here you’ll find a set of basic GeoPandas tools that allow you to go through the entire spatial analysis process — from loading the data to saving the results.

Loading Data

import geopandas as gpd

gdf = gpd.read_file("file.shp")

Basic Layer Information

gdf.head()         # data preview  
gdf.crs            # coordinate reference system  
gdf.plot()         # quick map  

Creating Geometry

from shapely.geometry import Point

point = Point(21.0, 52.2)
gdf = gpd.GeoDataFrame(geometry=[point])

Spatial Operations

gdf.buffer(100)             # buffer  
gdf.distance(gdf2)          # distance between objects  
gdf.intersects(gdf2)        # intersections  
gdf.contains(gdf2)          # contains  
gdf.within(gdf2)            # within  

Reprojection (Changing Coordinate System)

gdf.to_crs(epsg=2180)       # e.g., PUWG 1992  

Filtering Data (like in Pandas)

gdf[gdf["type"] == "forest"]    # filter  

Saving to File

gdf.to_file("result.shp")

Joining Data (merge)

gdf_joined = gdf.merge(table, on="id")
