    SFBayAreaLanSat_20021010 2002-10-10 USGS Imagery Auto Mask Tolerance: 2 Default for all other mask values. usgsLanSat.tif
    i3_15Meter_20041010 2004-10-10 i3 Auto Mask Default values. i3SF15-meter.tif

  2. Open a new Imagery Project and add each of the image resources to the project:

    • Resources/Imagery/BlueMarble
    • Resources/Imagery/SFBayAreaLanSat_20021010

    • Resources/Imagery/SFHighResInset_20061010
  3. Select the Support Historical Imagery checkbox.

  4. Select File > Save.

  5. Enter Projects/Imagery/SFBayAreaHistorical as the name of your project and click Save.

  6. Build the SFBayAreaHistorical project.
