Resumen

The Describe function returns the following properties for Mosaic Datasets. Raster Dataset properties and Dataset properties are also supported. Editor Tracking properties are supported if editor tracking has been enabled for this mosaic dataset.

A Mosaic Dataset returns a dataType of "MosaicDataset".

Propiedades

PropiedadExplicaciónTipo de datos
allowedCompressionMethods
(Sólo lectura)

The methods of compression that can be used to transmit the mosaicked image from the server to the client. This property influences an image service generated from the mosaic dataset.

  • None —No compression
  • LZ77 —LZ77 compression
  • JPEG —JPEG compression
  • LERC —LERC compression
String
allowedFields
(Sólo lectura)

The attribute table fields that are visible to the client when the mosaic dataset is served as an image service.

String
allowedMensurationCapabilities
(Sólo lectura)

The mensuration tools that can be used with an image service.

  • None — No mensuration tools can be used.
  • Basic — The Distance, Area, Point Location, and Centroid Location mensuration tool can be used.
  • Base-Top Height — The height of a structure is calculated by measuring from the base of the structure to the top of the structure.
  • Top-Top Shadow Height — The height of a structure is calculated by measuring from the top of the structure to the top of the structure's shadow on the ground.
  • Base-Top Shadow Height — The height of a structure is calculated by measuring from the base of the structure to the top of the structure's shadow on the ground.
  • 3D — Used to determine the heights of your 3D features, such as buildings, when a DEM is available.
String
allowedMosaicMethods
(Sólo lectura)

Specifies the order of the rasters mosaicked together to render the mosaicked display.

  • None — Orders rasters based on the order (ObjectID) in the mosaic dataset attribute table.
  • Closest to Center — Enables rasters to be sorted based on a default order in which rasters that have their centers closest to the view center are placed on top.
  • Closest to Nadir — Enables rasters to be sorted by the distance between the nadir position and view center. This is similar to the Closest to Center method but uses the nadir point to a raster, which may be different than the center, especially for oblique imagery.
  • Closest to Viewpoint — Orders rasters based on a user-defined location and nadir location for the rasters using the Viewpoint tool.
  • By Attribute — Enables raster ordering based on a defined metadata attribute and its difference from a base value.
  • North-West — Enables raster ordering in a view-independent way in which rasters with their centers to the northwest are displayed on top.
  • Seamline — Cuts the raster using the predefined seamline shape for each raster using optional feathering along the seams and orders images based on the SOrder field in the attribute table.
  • Lock Raster — Allows a user to lock the display of single or multiple rasters based on the ObjectID.
