Teerawat_WK2: Clarification Needed on Handling NULL Values in Assignment 2.4

[Teerawat Pholyiam]

Hi All,

For Assignment 2.4, I’ve faced NULL values in the “PrevPV” column within the attribute table which has impacted my final map visualization to display a bit different with example screenshot of Pv prevalence data. Based on the provided documentation and my completion tasks, is this handling these NULLs in this way acceptable? I want to ensure that my completion is aligning with the assignment requirements or I may miss following any steps in the instructions to verify the files.

Thank you!

Hi Teerawat,

Yes “null” value cannot be display on map and in the example also have it. You will notice that we put the other layer under the prevalence layer to makes displayed correctly (it’s grey on map).
