overview
We ensured that all data used in this project follow the below projection and coordinate system:
Projected Coordinate System: SVY21
Projection: Transverse_Mercator
Geographic Coordinate System: GCS_WGS_1984
Due to the limited availability of data in its machine-readable format, several datasets were digitised from PDF documents or images obtained from the Government websites. Where necessary, a variety of tools - such as Iso Cluster Unsupervised Classification and Elimination - was used to speed up the process of digitisation and removal of digitisation errors. The digitised data were also georeferenced using at least 10 well-distributed control points under a 1st Order Polynomial (Affine) transformation, and efforts were made to keep the total root-mean-square (RMS) error as low as possible.
