PointInPolygon

This package is used to check point inside/outside of polygon/multipolygon. It is supported polygon to array, convert multipolygon dataframe to polygon, find the min and max item in 2D array.

Install

pip install PointInPolygon

or

pip install --upgrade PointInPolygon

Usage

• Import package

import PointInPolygon as pnp

• Geometry Polygon to Array (skip steps to simplify the data and reduce the size of array, if it is multipolygon, it needs to convert to polygon first)

pnp.Geo2Array(geo, skip=0)

• Convert df multipolygon to polygon (the column name should be geometry)

pnp.MultiPolygon2Polygon(df)

• Check point in polygon (list or 2D tuple)

pnp.PointInPolygon(point, polygon)

• Get min value from array based on index

pnp.minValue(array, index)

• Get max value from array based on index

pnp.maxValue(array, index)
