Catalyst’s Historical Airphoto Correction workfl ow was designed to consider the various problems that are often encountered with historical imagery. Several factors make historical airphotos more diffi cult to process than standard airphotos, which include:
limited or incorrect metadata, large positional and orientation errors, poor fi ducial marks, poor quality imagery as well as changes in land cover over time.
Catalyst developed the HAP workflow as a way to provide a new method to preserve valuable historical air photos and return
them to operational use. NETR, and its subsidiary, HistoricalAerials.com have provided the early evidence of success that is starting
to pay dividends for itself, and its clients.
