サマリー
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".
プロパティ
プロパティ | 説明 | データ タイプ |
allowedCompressionMethods (読み取り専用) | The methods of compression that could be used to transmit the mosaicked image from the server to the client. This property influences an image service generated from the mosaic dataset.
| String |
allowedFields (読み取り専用) | The attribute table fields visible to the client when the mosaic dataset is served as an image service. | String |
allowedMensurationCapabilities (読み取り専用) | The mensuration tools can be used with an image service.
| String |
allowedMosaicMethods (読み取り専用) | The order of the rasters mosaicked together to render the mosaicked display.
| String |
applyColorCorrection (読み取り専用) | If color correction information is available in the mosaic dataset, then a value of True means it will be applied. | Boolean |
blendWidth (読み取り専用) | The distance used by the Blend mosaic operator. | Double |
blendWidthUnits (読み取り専用) | The units in which the blend width is specified.
| String |
cellSizeToleranceFactor (読み取り専用) | How mosaic dataset items with different pixel sizes are grouped together for some operations, such as mosaicking or seamline generation. | Double |
childrenNames (読み取り専用) | A list of side-table names that are components of the mosaic dataset. | String |
clipToBoundary (読み取り専用) | True means the image extent is limited to the geometry of the boundary. False means it is limited to the extent of the boundary. | Boolean |
clipToFootprint (読み取り専用) | Whether the extent of each raster is limited to its footprint. | Boolean |
defaultCompressionMethod (読み取り専用) | The default compression method for the image. This value comes from the list of methods returned by the allowedCompressionMethods property. | String |
defaultMensurationCapability (読み取り専用) | The default mensuration tool that will be used with an image service. This value comes from the list returned by the allowedMensurationCapabilities property. | String |
defaultMosaicMethod (読み取り専用) | The default mosaic method for the mosaicked image. This value comes from the list returned by the allowedMosaicMethods property. | String |
MosaicOperator (読み取り専用) | The default method for resolving overlapping cells.
| String |
defaultResamplingMethod (読み取り専用) | The default sampling method of the pixels.
| String |
SortAscending (読み取り専用) | The default ordering of the images defined by the mosaic methods.
| String |
endTimeField (読み取り専用) | The field that defines the end time. | String |
footprintMayContainNoData (読み取り専用) | True if NoData is a valid pixel value. | Boolean |
GCSTransforms (読み取り専用) | The transformations applied if the spatial references of the source rasters differ from the spatial reference of the mosaic dataset. | String |
JPEGQuality (読み取り専用) | The percentage of image quality retained if JPEG compression is used on this dataset. | Long |
LERCTolerance (読み取り専用) | The maximum error value applied per pixel if the mosaic dataset uses LERC compression. | Double |
maxDownloadImageCount (読み取り専用) | The maximum number of rasters that a client can download from an image service. | Long |
maxDownloadSizeLimit (読み取り専用) | The maximum size, in megabytes, of rasters that a client can download from an image service. | Long |
maxRastersPerMosaic (読み取り専用) | The maximum number of rasters mosaicked. This property affects an image service generated from the mosaic dataset. | Long |
maxRecordsReturned (読み取り専用) | Maximum number of records returned by the server when viewing the mosaic dataset as a published image service. | Long |
maxRequestSizeX (読み取り専用) | The maximum number of columns each time a mosaicked image is generated. | Long |
maxRequestSizeY (読み取り専用) | The maximum number of rows each time a mosaicked image is generated. | Long |
minimumPixelContribution (読み取り専用) | The minimum number of pixels needed within the area of interest in order for a mosaic dataset item to be considered as part of that area. | Long |
orderBaseValue (読み取り専用) | The images are sorted based on the difference between this value and the value specified in the orderField. This is applicable only for the By Attribute mosaic method. | Double |
orderField (読み取り専用) | The metadata attribute used for raster ordering. This is applicable only for the By Attribute mosaic method. | String |
rasterMetadataLevel (読み取り専用) | How much metadata will be transmitted from the server to the client.
| String |
referenced (読み取り専用) | True if it is a referenced mosaic dataset; False if it is a regular mosaic dataset. | Boolean |
startTimeField (読み取り専用) | The field that defines the start time. | String |
timeValueFormat (読み取り専用) | The format in which the start time and end times are specified. | String |
useTime (読み取り専用) | True if the mosaic dataset is time aware. | Boolean |
viewpointSpacingX (読み取り専用) | The horizontal offset used to calculate where the center of the area of interest (display view) is when you click an arrow button on the Viewpoint dialog box. These values are calculated in the units of the spatial reference system of the mosaic dataset. This is applicable only for the Closest to Viewpoint mosaic method. | Double |
viewpointSpacingY (読み取り専用) | The vertical offset used to calculate where the center of the area of interest (display view) is when you click an arrow button on the Viewpoint dialog box. These values are calculated in the units of the spatial reference system of the mosaic dataset. This is applicable only for the Closest to Viewpoint mosaic method. | Double |
