Data Attributes

Attribute Summary

Rubric Score Primary Key? Name Type Description
100
ObjectID INTEGER The unique identifier for the dataset. The ObjectID field is maintained by ArcGIS and guarantees a unique ID for each row in a table. It can be used as an image ID when using the Lock Raster mosaic method.
100
Name TEXT Display name for the catalog item (filename). Name of the source defined by the raster type, which can be the name of the raster dataset file or the metadata file defined in the raster type.
100
MinPS NUMERIC Minimum pixel size Value = 0 Computed from the LowPS and HighPS values and depend on the overlapping raster datasets. These values control which raster will be used to create the dynamically mosaicked image at particular scales or resolutions of the display or image request. For example, if you create a mosaic dataset from 1-meter source rasters and build overviews, you will see a range of minimum and maximum pixel sizes. If you view the entire mosaic dataset (fully zoomed out), you likely are viewing the image with the largest MinPS and MaxPS values. As you zoom in, the resolution of the image increases and smaller pixel sizes are required.
100
MaxPS NUMERIC Maximum pixel size Value = 20, 40, 80 Computed from the LowPS and HighPS values and depend on the overlapping raster datasets. These values control which raster will be used to create the dynamically mosaicked image at particular scales or resolutions of the display or image request. For example, if you create a mosaic dataset from 1-meter source rasters and build overviews, you will see a range of minimum and maximum pixel sizes. If you view the entire mosaic dataset (fully zoomed out), you likely are viewing the image with the largest MinPS and MaxPS values. As you zoom in, the resolution of the image increases and smaller pixel sizes are required.
100
LowPS NUMERIC Low pixel size Value = 2 Extracted from the source rasters and used to define the range of pixel sizes that the raster dataset contains. For example, a raster dataset that contains a pyramid (or internal overview) will have a range of pixel sizes—the low value will represent the base pixel value, and the high value will represent the top overview that is being used. For raster datasets with no pyramids, the low and high pixel sizes may be the same value.
100
HighPS NUMERIC High pixel size Value = 2, 4, 8 Extracted from the source rasters and used to define the range of pixel sizes that the raster dataset contains. For example, a raster dataset that contains a pyramid (or internal overview) will have a range of pixel sizes—the low value will represent the base pixel value, and the high value will represent the top overview that is being used. For raster datasets with no pyramids, the low and high pixel sizes may be the same value.
100
Category INTEGER Used for quickly identifying the type of dataset and its status within the mosaic dataset: 0 = Unknown, 1 = Primary, 2 = ServiceOverview, 3 = DerivedRaster, 255 = Custom Value = 1 (Primary [base] data)
100
Tag TEXT Identifies a dataset in a function template and indicates if the dataset is panchromatic, multispectral, or pan sharpened. Value = MS (multispectral)
100
GroupName TEXT The name of the groups used to link together datasets belonging to a particular project. Value = <ProductOrderID> ProductOrderID = Order Item ID of product Example: “052270730010_01_P001” ProductOrderID = Order Number + ProdDesc orderNumber = 12-digit DigitalGlobe Order Item number, underscore, and 2-digit delivery increment. “nnnnnnnnnnnn_mm” Example: “052265559010_01” prodDesc = Unique product identifier Example: “P001”
100
ProductName TEXT ImageDescriptor: The name of the product of the raster data provided by the data source. Combination of product name and product type. Value = ORstandard2A Standard (2A) Imagery products are radiometrically corrected, sensor corrected, and projected to a plane using the map projection and datum of the customer's choice (UTM 51S). All Standard Imagery products have uniform GSD (ground sample distance in meters) throughout the entire product. OrthoReady (2A) Imagery contains all the characteristics of the Standard (2A) product, however, Ortho Ready Standard Imagery has no topographic relief (DEM) applied with respect to the reference ellipsoid, making it suitable for orthorectification. Ortho Ready Standard Imagery is projected to a constant base elevation, which is calculated on the average terrain elevation per order polygon or can be supplied by the customer.

CenterX NUMERIC X-coordinate of the center of the raster's minimum bounding rectangle (UTM)
100
