Your shuksan.tif dataset has mixed-up coordinate systems. The thread includes some information on the installs and here is a little bit extra information. I hope this helps. This graphic might help you located the install on the side. It does not require additional license, just access to your organizational My Esri account. What is this additional coordinate system data come from and where is it installed? In short, how do I apply a vertical transformation to these data?Īdditional Coordinate System Data install can be downloaded from My Esri download page. Also, additional data (coordinate systems data) setup must be installed on the system By default, the Vertical parameter is unavailable and is only available when the input and output coordinate systems have a vertical coordinate system (VCS), and the input feature class coordinates have z-values. To perform a vertical transformation, check the optional Vertical parameter on the dialog box. Thinking that there must be something about the GeoTiff that Pro is not recognizing I ran the Define Projection despite the warning on the tool.Īfter running "Define Projection" the Project Raster tool still removed the vertical option once I added the GeoTiff suggesting the tool is again not seeing the vertical information. Trouble is, when I add my surface model to the Define Projection tool the Define Projection tool states that the data have vertical information. Thinking that the data must lack vertical information read that I can add vertical datum information using the *Define Projection* tool. I understand the vertical option is only available if and only if the data have vertical datum information. This checkbox disappears when I select my input raster. I see that the *Project Raster* tool includes a checkbox for applying vertical transformations. I would like to use the vertical datum conversion capabilities in ArcGIS Pro 2.7 to convert the GeoTiff to reference the NAVD88 vertical datum. I have a GeoTiff surface model and the z values reference EGM96.
