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 larger 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 larger 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.

  • 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
