I am trying to display the total length of utility pipes by using the indicator widget and using the sum statistic of the shape_length field, I am given an error with the data by trying this, and I am wondering if it is even possible to use this field for statistics, and if not, what my other options are.

I happened to have the same question today. I used a factor of 0.000189394 to convert feet to miles. I left the offset at zero. I'm creating a gauge that shows the number of feet of sewer pipe inspected to the total number of miles that should be inspected in one year.

To figure out the conversion factor I googled conversion factor feet to miles

Were you able to use shape_length as a statistic field for your gauge? I am trying to just show the length of sewer pipe in the region in miles with the indicator widget, I figured this would be simple in OD, but its been more complicated than I thought.

No. The source is actually a survey123 hosted feature service. When the form is opened from a map the shape_length value is passed into a hidden field.

Hi Kevin,

Please see my reply below from:

I believe that in order to see the Shape.STLength() field, it needs to be a map service.

This is because if you inspect the fields that display at the rest end point of a map service vs feature service, you will notice that the feature service does not list Shape.STLength() as part of its' available fields.

If it is a map service, then you will be able to do what Alexander Baker mentioned above.

 

 

Here are some other threads talking about this:

AGO Operations Dashboard - Chrome vs IE, SHAPE.STLength() field, multi-condition variables   (This one says that the error is no longer an issue.)

Operations Dashboard - use shape_length field?

I've tried using SHAPE.LEN from both a feature layer and a map image layer and both give the same "Cannot Access Data" error.  We had to create a spatial view of our SDE data and add a length column using ST_Length().  This is in Enterprise 10.6.1.  Hopefully ESRI figures out this bug in 10.7 or 10.7.1.
