I am working on data collection for underground utilities, so I need the ability to modify the altitude (z value) to reflect the utility depth. I know I can have multiple geopoints, as long as all but one have a "bind::esri:fieldType" that is not null. I also know to get the altitude, I have to set the same "bind::esri:fieldType" field to "esriFieldTypePointZ". How can I have a geopoint's "bind::esri:fieldType" set to "null" and "esriFieldTypePointZ" at the same time? Not sure I understand why Esri chose to use that field for unrelated purposes...
Any help would be greatly appreciated.
Thank you,
Nick
