GeoPandas with Python and AutoCAD

GeoPandas is an open source project to make working with geospatial data in python easier, I installed the library via PyPi

Sample data files can be downloaded from here

 

import traceback

import geopandas

 

from pyrx import Ap, Ax, Db, Ed, Ge, Gi

def makePline(pnts, model, color):

    pline = Db.Polyline(pnts)

    pline.setColorIndex(color)

    model.appendAcDbEntity(pline)

def doit():

    try:

        db = Db.curDb()

        model = Db.BlockTableRecord(db.modelSpaceId(), Db.OpenMode.kForWrite)

        gdf = geopandas.read_file("E:/townssurvey_shp/TOWNSSURVEY_ARC_GENCOAST.shp")

        #gdf = geopandas.read_file("E:/110m_cultural/ne_110m_admin_0_countries.shp")

        #do MultiPolygon first

        gdf0 = gdf.loc[gdf.geometry.geometry.type=='MultiPolygon']

        for mp in list(gdf0.geometry):

            for p in mp.geoms:

                makePline(list(p.exterior.coords), model, 1)

        gdf1 = gdf.loc[gdf.geometry.geometry.type=='Polygon']

        for p in gdf1.geometry:

            makePline(list(p.exterior.coords), model, 2)

        gdf2 = gdf.loc[gdf.geometry.geometry.type=='LineString']

        for p in gdf2.geometry:

            makePline(list(p.coords), model, 3)

    except Exception as err:

        traceback.print_exception(err)
