Hi all,

Is it possible to symbolise by age in ArcGIS Online Map Viewer on a Live Feature Class.

I can symbolise by age, however it requries that you set a date for the symbology to apply to, unfortunately you cannot select latest date for example.

If not possible I'll submit as an idea.


Cheers,

Cam

Hi Cameron McArtney‌,

This is an example arcade expression which classifies features based on current date.

if (DateDiff(Now(), Date($feature.Date_Stamp), 'days') <= 1) {
return "Features captured within the last day" }
else if (DateDiff(Now(), Date($feature.Date_Stamp), 'days') > 2 &&
DateDiff(Now(), Date($feature.Date_Stamp), 'days') < 5) {
return "Features captured between 2 to 5 days ago" }
else if (DateDiff(Now(), Date($feature.Date_Stamp), 'days') >= 5) {
return "Features captured more than 5 days ago" }
else {
return "None of these conditions" }‍‍‍‍‍‍‍‍‍

you can change days to hours, minutes, months, ....

Cameron McArtney‌, never done it before and just a suggestion, can you use arcade expression to get the age then apply the symbology? Similar to
