https://community.esri.com/t5/data-management-questions/compare-fields-values-from-time-stamp-data-based/m-p/1060900#M43340 <P>I need to compare features values from two datasets that collected every 5 years. So, if dataset A contains set of features and dataset B (which was collected after 5 years) contains other set of features, I would like to compare the % value changes (increase, or remain the same) of these features. The challenge is that there is no&nbsp; unique reference for each these points. The only reference are their locations based an offset measured from a common start point. However, the measuring can introduce error due to the time difference and accuracy of performing the measurement. So of a feature from dataset A is measured located away by 50.4 m form the a common feature, the same point&nbsp; can be measured from dataset B with error +/-&nbsp; (e.g. 49.2 or 53.6). This even also varies as the error is not consistent.&nbsp; &nbsp;</P><P>Any recommendations.</P> Mon, 24 May 2021 11:33:23 GMT ThamerTarabzouni 2021-05-24T11:33:23Z https://community.esri.com/t5/data-management-questions/compare-fields-values-from-time-stamp-data-based/m-p/1060900#M43340 <P>I need to compare features values from two datasets that collected every 5 years.
