If you are going to use the Generate OIS Obstacle Data (Aviation) tool to populate ObstacleJSON field in the Airports 18B schema, ObstructionIdSurface_MP - FeatureClass, you can use the Airports 18B schema, VerticalStructurePoint - FeatureClass for the input Obstacle features because it will use the VerticalStructurePoint.TYPE_CODE field when it populates the ObstructionIdSurface_MP.ObstacleJSON field .
To convert your CSV to points you can use XY Table To Point (Data Management) see https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/xy-table-to-point.htm
Once you make that output feature class, you can use the Append tool to append that feature class into VerticalStructurePoint.
NOTE: you dont have to use VerticalStucturePoint, its just good since it already has TYPE_CODE, but you would still need to populate that (maybe you have values in your CSV?) Otherwise, you can use the new feature class created from the XY Table To Point tool. You would just need to ensure you add and populate any field you want to see in the ObstacleJSON field values per the help at: https://pro.arcgis.com/en/pro-app/latest/tool-reference/aviation/generate-ois-obstacle-data.htm
See the section about fields where it says " Permissible field names are the following:"
If you have these fields - and they are populated, they will be included in the output ObstacleJSON.
Keep in mind you must also populate the Z values on the obstacles. You need to have a defined horizontal and vertical coordinate system on it too... so there is a fair amount of data prep that needs to be done!
I hope that helps!
