OneMap API to search and return custom region

#1

Hi All,

I am exploring the feasibility a feature to retrieve a relevant region boundaries set when user enter the postal code

Using the town council base map as an illustration example:

When user enters via either of the following:

  1. 1st 2 digits of the Postal code and select the returned result
  2. Full 6 digits postal code and hit search or enter

MND%20Town%20Council%20Boundaries
MND Town Council Boundaries.png1451×899 92.1 KB

The return result will show “West Code District” instead of “Jurong Point”

Can this be done via the API? How can I achieve this?

Thanks in advance :):wink:

Regards
Brian

If you know the FeatureCollection for Town Council Boundary Polygon, you can use Spatial Analysis using “Point Within Polygon” via TurfJS or other tools such as using python then you get the attribute name like “West Coast TC” for Town Council Boundary to be displayed.
