P_DASurveyReadings フィールドに関する質問

Question

Direct Assessment 調査のための DASurveyReadings レイヤーに関して質問があります。pson フィールドと dcpotentialvolts フィールドの違いは何でしょうか？ 完了した DCVG 調査では、調査請負業者が信号シフト（mV）とオーバーラインリモートアース（mV）の電圧測定値を提供しています。これらの値が既存の Esri データモデルのどのフィールドに属するのか、それとも拡張が必要なのかを知りたいと思っています。よろしくお願いいたします！

Hi @RichMosar,

Could you provide more details on the data and workflow you are capturing? Capturing signal shift and overline remote earth sounds more like indirect assessment and this feature class is geared toward direct assessment.

From my understanding, many readings are taken via the indirect method which may (or may not) warrant storage in a system of record, but used to drill down on where to perform direct assessment. It is also my understanding that when doing the direct assessment, signal shift and overline remote earth are not taken.

Thank you for posting the question. It is impossible for the data model to reflect each utility's unique workflows, and extending the data model to meet your specific needs is expected. That being said, I would like to learn more so we can be sure that the data model supports the workflows that are common to all utilities. Please also take a look at the P_CPTestPointReading and P_CPRectifierInspection to see if these would meet your need.
