Browse Footprint Attributes

Select the Mosaic Dataset in the Datasource list, and right-click Browse Footprint Attributes to open the Mosaic Dataset attribute table, which is actually the attribute table of the contour line, in which each record corresponds to a contour object. Contents of main fields in the attribute table:

Figure: Property table
  • SmFileName: File Name (excluding extension) added to all Original Images managed in Mosaic Dataset and Overview File Name (including extension).
  • SmPath: The full path (absolute path) added to all the original Image Files managed in Mosaic Dataset and the full path of the overview file. These paths support the network share path. Therefore, the shared use of Mosaic Dataset can be achieved by editing this field.
  • SmCategory: used to identify whether the currently displayed image within the image outline is the original Image Files or the overview. 1 indicates the original Image Files; 2 indicates the overview.
  • SmMinPS and SmMaxPS: are obtained from LowPS/HighPS calculations. These two values are used to control the resolution of the grid used to create the dynamic mosaic image when the image is displayed. Generally, if there is no overview, the SmMinPS value is 0 and the SmMaxPS value is HighPS * 10. For example, if the multi-spectral band SmLowPS = 8m and SmHighPS = 16m, then SmMinPS = 0 and SmMaxPS = 160. The unit of SmMinPS/SmMaxPS is the map unit. If the map is a longitude and latitude coordinate system, the unit of value is degrees. If the map is a Projected Coordi Nate System, the unit of value is meters.
  • SmLowPS and SmHighPS: Read from Raster Data to define the minimum and maximum resolution that Raster Data contains. The unit of the data value is different according to the Mosaic Dataset coordinate system. For the longitude and latitude coordinate system, the unit of the data value is degree; for the Projected Coordinate System, the unit of the data value is meter. For example, for the data of multi-spectral and panchromatic bands of Gaofen-1, the resolution of multi-spectral band of Gaofen-1 is 8 meters, and the resolution of panchromatic band is 2 meters. In the absence of pyramid, SmLowPS/SmHighPS values in the attribute table are equal. After Create Pyramid, the LowPS value is the base resolution, and the HighPS value represents the resolution of the top pyramid pixel. Therefore, for the multi-spectral band of Gaofen-1, the base resolution is 8m, and the top pyramid pixel resolution is 16m; for the panchromatic band, the base resolution is 2m, and the top pyramid pixel resolution is 16m.
  • SmZOrder: The default value is 1. The user can modify the value of this field to control the Display Order of the image. The Display Order of the conventional image is displayed in the reverse order of SmID. See Display Order Settings for details.
