Problem Identification and Resolution Form (PIRF)
As LAR-IAC2 participants have a chance to begin to look over recent deliveries of ortho imagery, it is expected that questions will arise regarding potential data errors. With such a tremendous volume of data, it is quite possible that such instances will be found. While each of the imagery tiles went through the independent QA/QC process, the possibility that some errors passed through is feasible. Moreover, some errors may be found that were not correctible through the QA/QC process.
All errors should be sent to the Department of Regional Planning (DRP) using the Problem Identification and Resolution Form (PIRF), which can be downloaded at the link below. It is preferable that you include a shapefile outlining the error along with the PIRF form (point, line or polygon, depending on the extent of the error). DRP will collect the errors and evaluate whether they fall within the specifications outlined in the contract. Errors will then be sent on to the contractor for resolution. Any corrected tiles will be placed on the DRP’s FTP site for downloading or put on DVD/CD media for the affected cities/agencies.
