The land use is based on detailed polygon land use data by state, obtained from PLANMalaysia (Department of Town and Country Planning, Malaysia). This polygon dataset was reclassified and rasterized. Gaps were infilled using the global CCI Land Cover map from the European Space Agency. Residential areas were split into rural and urban, as identified by the Global Human Settlement Urban Centre Database. Paddy fields were either derived from the detailed polygon land use data (where available) or located and vectorized by consulting rice cultivation maps. All analyses were completed in QGIS.

Gridded land use map of Peninsular Malaysia with a resolution of approximate 25 metres for the year 2018. The map includes nine different classes: 

1) non-paddy agriculture, 

2) paddy fields, 

3) rural residential, 

4) urban residential, 

5) commercial/institutional, 

6) industrial/infrastructure, 

7) roads, 

8) urban

9) others. 

The land use map was created as part of a project researching areas of Peninsular Malaysia particularly vulnerable to flooding.
