Go get a TIGER line file, at https://www.census.gov/cgi-bin/geo/shapefiles/index.php . 2. Using the OpenData plugin, open the .shp file contained in the .zip file. 3. Receive the error in the attachment, 'Unable to find a strict mathematical translation'. ==== What is the expected result? IMO, JOSM should be able to find the translation for this set, given all TIGER lines seem to come in this projection. The .prj file elements (what's there, and what isn't) suggest that this is ESRI 4269, see https://gis.stackexchange.com/a/27713 and https://epsg.io/4269 . ==== What happens instead? JOSM doesn't see {{{ GEOGCS[""GCS_North_American_1983"",DATUM[""D_North_American_1983"",SPHEROID[""GRS_1980"",6378137,298.257222101]],PRIMEM[""Greenwich"",0],UNIT[""Degree"",0.017453292519943295]] }}} as a meaningful projection. The OGC WKT on https://epsg.io/4269 indicates: {{{ GEOGCS[""NAD83"",DATUM[""North_American_Datum_1983"",SPHEROID[""GRS 1980"",6378137,298.257222101,AUTHORITY[""EPSG"",""7019""]],TOWGS84[0,0,0,0,0,0,0],AUTHORITY[""EPSG"",""6269""]],PRIMEM[""Greenwich"",0,AUTHORITY[""EPSG"",""8901""]],UNIT[""degree"",0.0174532925199433,AUTHORITY[""EPSG"",""9122""]],AUTHORITY[""EPSG"",""4269""]] }}} Same core elements, slightly different fields, but with the key addition of the EPSG authorities. Can JOSM translate one to the other to accept that this is 4269, if it's agreed this is correct? ==== Please provide any additional information below.
