bedankt voor je vraag. Ja, de Cadasta Tools kunnen hoogte vastleggen in een driedimensionale kenmerklaag. Hoewel dit geen standaardinstelling is die in alle enquêtes wordt gevonden, the z-value can be enabled by inputing esriFieldTypePointZ into the binden::esri:veldType field in the Enquêtes tabblad. You may want to consider using an external GNSS receiver in addition to the mobile collection device (smartphone or tablet) as this improves measurement consistency. If you need to capture the point values in separate fields, then you will want to create an additional question in the data collection form. This additional question would be hidden, use a pulldata function in the berekening field, and be set as esriFieldTypeDouble in de binden::esri:veldType field.
