When you click an image in the Data sources section of the Maps Engine catalog, the Data details page displays information about the image and its settings.
Anyone with access to an imagery data source can edit these attributes: Name, Description, Tags, Attribution, Acquisition, Shared with, and Accessible by. You can't edit the system-captured information.
These additional details provide more information about the image.
|Bands||The image type, such as RGB (with three bands) or Greyscale (with one band).|
|Image size||The size of the image, according to this formula:
In this formula, h represents horizontal-pixels, v represents vertical-pixels, and b represents the number of bands.
|Raw size/Uploaded size||Raw size is the size of the file on our servers; uploaded size is the size of the file that you uploaded. The sizes are different because you can upload in any GDAL-compliant projection and Google Maps Engine stores the uploaded file in its original format. However, Google Maps Engine sanitizes and reformats the file upon adding it to your data catalog, possibly resulting in a different size.|
|Resolution/max zoom||Resolution is the geographic distance represented per pixel in the source image. Max zoom specifies the zoom level at which maximum resolution of the imagery appears. The range is 0-24.
At zoom level zero (0), the entire world can be seen on one map. In contrast, at zoom level 24, individual buildings are visible. Each zoom level doubles the precision of the previous level in both horizontal and vertical dimensions. For more information, refer to the Google Maps API documentation.
|Bounds||The latitudinal and longitudinal coordinates of the area covered by the imagery.|
|Image masking: Processing mode||Image masking determines the way that Maps Engine handles fill areas of an image. For information on the masking options, see Masking images.|
