Selecting a chip from the chip database

In the OrthoEngine ChipDatabase window you navigate through the chip database to select the chip you want to use as the source of the GCP coordinates.

  1. In the OrthoEngine ChipDatabase window, do one of the following:
    • Click the # button, type the chip ID or chip sequence number, and then click OK.
    • Use the navigation buttons to select chip.
    • Click Search Criteria to narrow the search for chips to a manageable number of chips and then use the navigation buttons to select chip.
    • Type the chip ID in the Chip ID box under Chip Information and then press Enter. Detailed information about the currently selected chip appears under Chip Information. Click More Info to view detailed header and chip information.
  2. If you want to change the position of the GCP in the chip, select a new point in the chip image and click Cursor Position is GCP. To change the GCP location in a chip, the Chip Database must be writeable and the chip image must be geocoded. OrthoEngine attempts to find the corresponding feature in your raw image and positions the cursor on the feature. The feature's Easting and Northing coordinates appear in the Collection window.
  3. Click Use Image Chip in the OrthoEngine ChipDatabase window.

If you need to enhance the chip image to determine the position of the ground coordinate, you can:
