Visualisation of rainfall data across 184 KSNDMC rain gauges (Bengaluru Urban District) over the past 3 years

Here are the maps that visualise the rainfall dataset I received from KSNDMC. The following data pertains to the Bengaluru Urban District only and has been updated till 2017.

*Notes 

• The accuracy of my maps completely depends on the accuracy of the data provided to me by KSNDMC
• The word ‘Year’ in the information boxes in the interactive Rain Gauge Locations Maps refers to the annual rainfall value in millimetres. 
• My heat maps provide only a fixed sphere of influence (radius) for each rain gauge and therefore, will not prove useful if you zoom in too much. 
• However, if you want to a more detailed heat map that allows you to zoom into specific regions and still see a colour gradient (trend) then make a copy of my fusion table (through the link provided) and change the ‘radius’ to 50 (or any high value)
