ArcGIS Enterprise Marketplace Linux operating system comes with ArcPy. Thus, it is possible to run Mosaic Dataset Configuration Script (MDCS) script (in theory).

Step-by-Step Guide for Creating a Table/Raster Catalog

  1. Copy the entire contents of mdcs-py/blob/master/scripts to working directory
  2. Modify raster_type section of MDCS.xml
  3. Specify table (in comma-separated value [CSV]) location
  4. Edit the Raster column of input table .csv file. It must be local and a raster proxy. You can test a sample raster proxy file from OptimizeRasters 2.0. You can use a VRT file here if you'd like to use MRF in S3.
  5. If you want to visualize mosaic dataset with ArcGIS Pro on a Windows machine, set the path that exists in both the Windows Server and the Linux Server. You can keep adding more VRT files as long as object id and time are unique.
  6. To make the visualization work, make sure that the Windows Server has S3FullAccess role attached in the EC2 instance. Then, check that the Source value in the VRT file starts with vsis3/.

Step-by-Step Guide for a Raster Dataset

This is useful for creating a mosaic set from a set of TIF files that resides in a directory.

  1. Copy the entire contents of the MDCS Python scrips from GitHub to a working directory
  2. If you use Raster Dataset for rasterType, you can create mosaic from MRFs. Put the MRF files under the data_path
  3. Disable DF and AI in MDCS.xml if you don't use Table / Raster Catalog for rasterType

Note: MDTools_Setup.exe cannot be installed. MDTools is a set of command line tools that simplifies some common management tasks when working with rasters in a mosaic dataset.

Error 999999

Arcpy throws an error when it adds an item. This is a known issue for the Linux platform according to Abhijit at Esri. It doesn't happen on Windows.

Installing Missing Packages

  1. conda install pip
  2. "z:\home\arcgis\bin\Python\envs\test\Scripts\pip.exe" install logger

Use of py cache (.pyc) files and Python version

Use of solutionsLib.pyc is not compatible with Python3. Always use the GitHub MDCS source.

Z:\home\arcgis\src\SDT-56>"z:\home\arcgis\bin\Python\envs\test\python.exe" MDCS.py 
Traceback (most recent call last):
  File "MDCS.py", line 34, in <module>
    import solutionsLib  # import Raster Solutions library
ImportError: bad magic number in 'solutionsLib': b'\x03\xf3\r\n'
</module>

Troubleshooting

If MDCS hangs, try to restart the server using the startup scripts under /arcgis/server/.
