You can use a statistical software like spss, pspp, or R. Extract the atribut data from spatial dataset.

Dear Sangita

If u want to create ROC curve inside ArcGIS then, you may use ArcSDM tool box. Further you can use R or SPSS also but u have to extract data to ASCII or other tabular format.

Thank you Moh. Debe and Achu Ashok for your answer. I have already use the SPSS to create ROC curve but I am not sure whether I have done right or wrong. when i am plotting prediction accuracy after separating the data set under Agree and Disagree it is coming 75% (by dividing Agreed value by total well yield data) but AUC is showing 65%. Before processing SPSS I have categorized my dataset into Agree with 1 and Disagree with 0. then i imported the actual yield data and Column marked with 0 and 1 to create ROC curve. Is this the right procedure to create ROC in SPSS? or if not please tell me proper procedure.

Dear Sangita Dey,

sorry for late response, the groundwater potential zones is probability data? if yes, I think the procedure is right.

How do I generate ROC curves in the ArcGIS environment for model validation, especially for landslide susceptibility maps or hazard maps?

To generate ROC (Receiver Operating Characteristic) curves in the ArcGIS environment for validating groundwater potential zones, you can follow the steps below:

By following these steps, you can generate ROC curves in the ArcGIS environment for validating groundwater potential zones.
