ArcGIS Coordinate Systems Data

[JonathanLevy_Harbors]

I am looking for the ArcGIS Coordinate Systems Data download for ArcPro 3.2.2 on My ESRI.  Cannot seem to find it.  I am trying to convert LiDAR from MSL to MLLW.

I'm having the same problem

I found the solution. Follow the instructions at this link: https://pro.arcgis.com/en/pro-app/latest/help/mapping/properties/arcgis-coordinate-systems-data.htm
Within your my esri page, you will click on downloads and then on the version of ArcGIS pro that appears. A page will then appear where you have to scroll down to data and content, there will be the ArcGIS Coordinate Systems Data file.

There is no "Downloads" button/section/menu/link on my My Esri page.

I'm having the same problem but I'm signing is as a student on my.esri through my institution in the UK. I don't see "downloads" on the my.esri landing page. I need a geographic transformation for ArcGIS Pro which must have disappeared or wasn't needed when I updated to the latest version of ArcGIS pro. What do I do?

Thanks in advance.

well, Lidar derived elevations are originally referenced to a Geoid elevation or NAVD88. Those elevations are in reference to a fixed geoid model, while MLW and MLLW are not. Translation to tidal datums should be done based on the published survey data for a specific tidal station (s). See tidal.gif (880×680) for reference.
