2 MIN BEGINNER POLYGON, MAP FEATURE, WHAT IS A POLYGON, BOUNDARY DATA


Most companies are interested in maps with polygons or shapefiles. Postal code polygons can give more information about the exact boundaries of a certain area. These boundaries are drawn by adding a great amount of points that are connected to each other.

The Netherlands 4-digit postal code polygons

To draw a polygon on the map, you need a specific geometry (GEOM) in your dataset. The geometry in a dataset is more difficult to produce. In contrast to drawing points on the map, polygons need a certain geometry where every connection point is described with Latitude and Longitude values. That makes the geometry of a polygon a very large line of characters, because every connecting point should have a latitude and longitude.

Want to know what this looks like? This is an example of the geometry (shape) data of the Netherlands:

“geometry”:{“type”:”Polygon”,”coordinates”:[[[6.074182570020923,53.510403347378144],[6.905139601274129,53.48216217713065],[7.092053256873896,53.144043280644894],[6.842869500362383,52.22844025329755],[6.589396599970826,51.852029120483394],[5.988658074577813,51.851615709025054],[6.15665815595878,50.80372101501058],[5.606975945670001,51.03729848896978],[4.973991326526914,51.47502370869813],[4.047071160507528,51.26725861266857],[3.314971144228537,51.34575511331991],[3.830288527043137,51.62054454203195],[4.705997348661185,53.091798407597764],[6.074182570020923,53.510403347378144]]]}.
