I think those DTW data came from data source from government department or ministry

I search on google and find some map service related to DTW

In arcgis you simply add a map service and put the appropriate link to the map server that serve DTW map

In my country we dont have such "ready and serve" data

so we build manually by analyzing satellite image with IR band, and separate wet area with non-wet area

using remote sensing software such as ENVI and export it to ArcGIS as a vector data
