Hi all, I'm trying to figure out how to correctly handle projecting GEOS 16 / 17 data with GeoTools.
My initial attempt was via data imported through gdal_translate, so I started asking here: https://lists.osgeo.org/pipermail/proj/2019-June/008675.html <https://www.google.com/url?q=https://lists.osgeo.org/pipermail/proj/2019-June/008675.html&sa=D&usg=AFQjCNHQlTTVWYkpwMESXvRpXiYzhNm5lw> Source rasters: gsutil cp gs://gcp-public-data-goes-17/ABI-L1b-RadC/2019/151/21/OR_ABI-L1b-RadC-*_G17_s20191512131197_*.nc . Earth Engine screen shots: https://photos.app.goo.gl/sW1upk1iZ9p62MuY9 https://photos.app.goo.gl/UAGccF2rjPDfenS27 However, I can bypass to write any WKT into the raster's info on the GeoTools side. Is there anything I can add to do the same thing as the proj extension that Even has via the NetCDF gdal driver? e.g. EXTENSION["PROJ4","+proj=geos +lon_0=-137 +h=35786023 +x_0=0 +y_0=0 +ellps=GRS80 +units=m +no_defs +sweep=x"]] Looking through GeostationarySatellite.java, GEOS.txt, GeostationarySatelliteTest.java, I don't see any mention of sweep I see adapted from: https://github.com/OSGeo/proj.4/blob/4.9/src/PJ_geos.c I don't see the 2012 / 2013 initial changes for sweep axis. <https://github.com/geotools/geotools/blob/master/modules/library/referencing/src/main/java/org/geotools/referencing/operation/projection/GeostationarySatellite.java>So I presume not the changes since that are now it: https://github.com/OSGeo/PROJ/blob/master/src/projections/geos.cpp I presume that we would need to add sweep support and some mechanism to support setting it, yes? https://github.com/geotools/geotools/blob/master/modules/library/referencing/src/main/java/org/geotools/referencing/operation/projection/GeostationarySatellite.java https://github.com/geotools/geotools/blob/master/modules/library/referencing/src/test/resources/org/geotools/referencing/test-data/scripts/GEOS.txt https://github.com/geotools/geotools/blob/master/modules/library/referencing/src/test//java/org/geotools/referencing/operation/projection/GeostationarySatelliteTest.java I happen to be using GeoTools 19, but I'm fine back porting things if necessary. Thanks! -kurt
