postgis - How can I convert SRTEXT to PROJ4TEXT with QGIS

Saturday 31 March 2018

I have a SRTEXT like this: GEOGCS["My Data",DATUM["Not specified (.....

I want to get PROJ4TEXT of this STREXT.

Can I get it from QGIS. Because I want to insert it in Postgresql SPATIAL_REF_SYS table. (or I need PROJ4TEXT data to use this projection)

Answer

You can write the text (which is called WKT) into a text file mycrs.prj , and run gdalsrsinfo on that. Running in the OSGE4W (or Linux/MAC) shell

gdalsrsinfo mycrs.prj >out.txt

should report the proj4 string and the WKT definition for postgis.
