Superseded vertical grid shifts not in TransformerGroup #1261
Comments
This is where those options are hardcoded in the TransformerGroup: pyproj/pyproj/_transformer.pyx Lines 205 to 214 in f5466df
If you would like them to be dynamic, a MR adding support for that is welcome. |
@snowman2 Sounds good, I'll give this a shot. Is there a contributor's guide I should follow? I looked and didn't see one. Also, if there's a vaguely similar PR that you think would be a good model to follow that would be super helpful. |

Problem description
I am trying to transform NAD83 ellipsoidal heights to NAVD88 orthometric heights with a variety of geoid models. For some reason, the
geoid12b
geoid model using grid fileus_noaa_g2012bu0.tif
is not one of the transformers returned byTransformerGroup(6319, 5703)
. I've only been able to make it appear directly viaTransformer.from_pipeline('epsg:6326')
.Expected Output
I was able to make this appear as Operation No. 2 in
projinfo
if and only if I set--show-superseded
and--spatial-test intersects
. Is this the reason they are not listed in the TransformerGroup? If so, is there an equivalent for these in PyProj?Environment Information
Installation method
