Points

Points represents a set of point geometries — individual plants, sampling locations, detections. It subclasses geopandas.GeoDataFrame and shares the same basics as the other types (CRS conversions, table utilities, save() — see the Lines page for the list).

from shapelib import read_file

points = read_file("plants.gpkg")

Neighbor distances

The average distance from each point to its nearest neighbor — useful to estimate planting density:

avg = points.calculate_average_nearest_neighbor_distance(max_distance=30.0)

Buffering

circles = points.buffer_m(1.0)   # circular buffers, in meters -> Polygons

Rasters

Points converts to and from raster masks:

points = Points.from_mask(mask, dataset_reader=orto)
mask = points.to_mask(dataset_reader=orto)

See Raster converters for details.
