Polygonkoordinaten zu PostgreSQL/PostGIS

Question

Ich habe eine Geojson-Datei mit Polygonkoordinaten. Versuchen, die Koordinaten in PostgreSQL-Datenbank in Python mit dem Psycopg2 API einzufügen. Hier sind die Koordinaten ich arbeite mit

"geometry": { "type": "Polygon", "coordinates": [ [ [ -74.0407457, 40.7130407 ], [ -74.0406424, 40.7130291 ], [ -74.0406471, 40.7130128 ], [ -74.0406625, 40.7130141 ], [ -74.0406659, 40.7130016 ], [ -74.0406531, 40.7129996 ], [ -74.0406377, 40.7129826 ], [ -74.0406401, 40.7129721 ], [ -74.04062, 40.7129693 ], [ -74.0406173, 40.7129823 ], [ -74.0405894, 40.7129785 ], [ -74.0405874, 40.7129932 ], [ -74.0405764, 40.7129914 ], [ -74.040574, 40.7129998 ], [ -74.040519, 40.7129937 ], [ -74.0405227, 40.7129752 ], [ -74.0404268, 40.712964 ], [ -74.0404235, 40.7129823 ], [ -74.0403662, 40.7129765 ], [ -74.0403675, 40.7129671 ], [ -74.0403578, 40.712966 ], [ -74.0403605, 40.7129508 ], [ -74.0403303, 40.7129475 ], [ -74.0403326, 40.7129368 ], [ -74.0403165, 40.7129348 ], [ -74.0403149, 40.7129465 ], [ -74.0402931, 40.7129571 ], [ -74.04028, 40.7129551 ], [ -74.040276, 40.7129698 ], [ -74.0402941, 40.7129737 ], [ -74.0402917, 40.7129805 ], [ -74.0403102, 40.7129828 ], [ -74.0403028, 40.7130151 ], [ -74.0403256, 40.7130184 ], [ -74.0403179, 40.7130608 ], [ -74.0403085, 40.7130596 ], [ -74.0403071, 40.7130669 ], [ -74.0402867, 40.7130646 ], [ -74.0402827, 40.7130875 ], [ -74.0402706, 40.7130862 ], [ -74.0402689, 40.7130962 ], [ -74.0402522, 40.7130944 ], [ -74.0402495, 40.7131083 ], [ -74.0402629, 40.7131104 ], [ -74.0402773, 40.7131251 ], [ -74.040275, 40.7131371 ], [ -74.040291, 40.7131388 ], [ -74.0402931, 40.7131256 ], [ -74.0403256, 40.7131292 ], [ -74.0403286, 40.7131144 ], [ -74.0403387, 40.7131155 ], [ -74.0403407, 40.7131078 ], [ -74.040398, 40.7131147 ], [ -74.040394, 40.713131 ], [ -74.0404902, 40.7131434 ], [ -74.0404939, 40.7131272 ], [ -74.0405492, 40.7131327 ], [ -74.0405469, 40.7131401 ], [ -74.0405573, 40.7131414 ], [ -74.0405546, 40.7131546 ], [ -74.0405864, 40.7131594 ], [ -74.0405841, 40.7131709 ], [ -74.0405978, 40.7131726 ], [ -74.0405998, 40.7131635 ], [ -74.040623, 40.7131516 ], [ -74.0406364, 40.7131531 ], [ -74.0406394, 40.7131363 ], [ -74.0406226, 40.7131343 ], [ -74.0406257, 40.7131211 ], [ -74.0407266, 40.713133 ], [ -74.0406843, 40.7133394 ], [ -74.0401087, 40.7132723 ], [ -74.0401036, 40.7132987 ], [ -74.0400151, 40.7132885 ], [ -74.0400165, 40.7132847 ], [ -74.0399266, 40.7132743 ], [ -74.0400315, 40.712747 ], [ -74.0407879, 40.7128354 ], [ -74.0407457, 40.7130407 ] ], [ [ -74.0400371, 40.7131942 ], [ -74.0401257, 40.7132042 ], [ -74.0401615, 40.7130218 ], [ -74.0400729, 40.7130118 ], [ -74.0400371, 40.7131942 ] ] ] } 

in Postgres einzufügen sie müssen in diesem Format sein (die nachstehenden Koordinaten von http://www.postgis.net/docs/ST_GeomFromText.html)

SELECT ST_GeomFromText('POLYGON((-71.1776585052917 42.3902909739571,-71.1776820268866 42.3903701743239, 
-71.1776063012595 42.3903825660754,-71.1775826583081 42.3903033653531,-71.1776585052917 42.3902909739571))'); 

Wesentlichen die Liste muss ein Tupel sein und die Koordinatenpaare dürfen keine Kommas haben, die die lat langen Werte trennen und es kann nicht '' oder '' um die Koordinaten geben.

Ich kann keinen Weg finden, diese Art von Datenformat

zu erstellen 0

ich dies versucht haben:

geojson = json.dumps(i['geometry']) 
qry = "insert into AbeBuildings (geom) values(ST_SetSRID(ST_GeomFromGeoJSON(%s), 4326));" 
cur.execute(qry,(geojson)) 

Fehler sagt

{"type": "Polygon", "coordinates": [[[-74.0410635, 40.7112018], [-74.0409077, 40.7119448], [-74.0408936, 40.7119431], [-74.0402319, 40.7118572], [-74.0403913, 40.7111239], [-74.0406334, 40.711153], [-74.0405859, 40.7113794], [-74.0406154, 40.7113997], [-74.0407442, 40.7114119], [-74.0407737, 40.7113936], [-74.04082, 40.7111725], [-74.0410635, 40.7112018]], [[-74.0406941, 40.7118065], [-74.0407382, 40.7116013], [-74.0405315, 40.7115758], [-74.0404874, 40.711781], [-74.0406941, 40.7118065]]]}

Answer 1

psycopg2 Argumente eine Liste oder ein Tupel sein erfordert, von Ihnen angegebene nur einen Wert. Versuchen Sie Folgendes:

cur.execute(qry, (geojson,))
