Now that the new dataset is uploaded and ready for processing, click “Order SFM Processing” to start an order. All image collections will be listed, including your latest upload. Select your Image Collection (Providence).

The next screen will display all scene origins used for processing an SFM model. During Upload, a scene origin is automatically created for you to used, based on the available GPS information. The name will tell you which origin belongs with your scene. It is best to pick the same origin associated with your cameras (due to transformation errors), but it is not necessary. Select your scene origin (KRT Origin Providence).

The SFM processing job is ordered, and a summary screen displays the origin and images used for processing

Clicking "Tasks" in the upper right will reveal the current SFM Status. First, the images are copied from the Image server to the Processing server. Next each image is processed for SIFT, and then a matching process begins, as seen in the previous figure. The matching processing is the most time consuming with large datasets (greater than 50 images). After that the SFM begins and the database is updated with new cameras upon success. Once the order is complete, revisit the Tie Point Creator to view the new cameras.
