ParameterExplanationData Type
in_mosaic_dataset

The mosaic dataset whose properties need to be set.

Mosaic Layer
rows_maximum_imagesize
(Optional)

The maximum number of rows for the mosaicked image, generated by the mosaic dataset for each request. This can help control how much work your server has to do when clients see your imagery. A higher number will create a more detailed image, but will also increase the amount of time to process the mosaic dataset. It is possible to set the value too small, and the image may not display.

Long
columns_maximum_imagesize
(Optional)

The maximum number of columns for the mosaicked image, generated by the mosaic dataset for each request. This can help control how much work your server has to do when clients see your imagery. A higher number will create a more detailed image, but will also increase the amount of time to process the mosaic dataset. It is possible to set the value too small, and the image may not display.

Long
allowed_compressions
[allowed_compressions,...]
(Optional)

Define the method of compression for transmitting the mosaicked image from the computer to the display (or from the server to the client).

  • None —No compression will be used.
  • JPEG — Compresses up to 8:1 and is suitable for backdrops
  • LZ77 — Compresses approximately 2:1. Suitable for analysis.
  • LERC —Compresses between 10:1 and 20:1. Compresses fast and is suitable for serving raw imagery with high bit-depth (12-bit to 32-bit)
String
default_compression_type
(Optional)

Set the default compression type. The default compression must be in the allowed_compressions list or already set in the mosaic dataset's Allowed Compression Methods property.

String
JPEG_quality
(Optional)

The compression quality when using JPEG. Compression quality ranges from 1 to 100. A higher number means better image quality but less compression.

Long
LERC_Tolerance
(Optional)

Limits the per pixel error when using LERC compression. This value is specified in the units of the mosaic dataset. For example, if the error is 10 centimeters and the mosaic dataset is in meters, enter 0.1.

Double
resampling_type
(Optional)

Determines how pixel values will be calculated when the dataset is displayed at small scales. Choose an appropriate technique based on the type of data you have.

  • NEAREST —The fastest resampling method, and it minimizes changes to pixel values. Suitable for discrete data, such as land cover.
  • BILINEAR — Calculates the value of each pixel by averaging, based on distance, the values of the surrounding 4 pixels. Suitable for continuous data.
  • CUBIC —Calculates the value of each pixel by fitting a smooth curve based on the surrounding 16 pixels. Produces the smoothest image, but can create values outside of the range found in the source data. Suitable for continuous data.
  • MAJORITY —Determines the value of each pixel based on the most popular value within a 3x3 window. Suitable for discrete data.
String
clip_to_footprints
(Optional)

Often the raster dataset and its footprint have the same extent. If they differ, you can clip the raster dataset to the footprint.

  • NOT_CLIP —Do not clip the raster to the footprint. This is the default.
  • CLIP —Clip the rasters to the footprint.
Boolean
footprints_may_contain_nodata
(Optional)

Allow for pixels that have NoData values.

  • FOOTPRINTS_MAY_CONTAIN_NODATA —Show pixels with NoData values. This is the default.
  • FOOTPRINTS_DO_NOT_CONTAIN_NODATA —Do not show pixels with NoData values. Note that while you may see an improvement in performance, if your imagery does have NoData values, they will appear as holes in your mosaic dataset.
Boolean
clip_to_boundary
(Optional)

Often the mosaic dataset and its boundary have the same extent. If they differ, you can clip the mosaic dataset to the boundary.

  • CLIP — Clip the mosaicked image to the boundary. This is the default.
  • NOT_CLIP —Do not clip the mosaicked image to the boundary.
Boolean
color_correction
(Optional)

Enable color correction on the mosaic dataset.

  • NOT_APPLY —Keep color correction off. This is the default.
  • APPLY —Use the color correction that has been set up for the mosaic dataset.
Boolean
allowed_mensuration_capabilities
[allowed_mensuration_capability,...]
(Optional)

Choose which measurements your viewers can perform on the mosaic dataset. The ability to perform vertical measurements is dependent on your imagery and may require a DEM.

  • None —No mensuration capabilities will be allowed.
  • Basic — Allow ground measurements such as distance, point, centroid, and area calculations.
  • Base-Top Height —Allow measurements from the base to the top of features. Rational polynomial coefficients must be imbedded within the imagery.
  • Base-Top Shadow Height —Allow measurements from the base of a feature to the top of its shadow. Sun azimuth and sun elevation information is required.
  • Top-Top Shadow Height —Allow measurements from the top of a feature to the top of its shadow. Sun azimuth, sun elevation, and rational polynomial coefficients are required.
  • 3D —A DEM must be available.
