This Google Group was created in 2018 as a continuation of the Usenet group comp.lang.idl-pvwave, which was overrun by spam. It was for discussion of the Interactive Data Language (IDL), developed by NV5 Geospatial Corporation ( IDL Software Programming Language | Interactive Data Visualization). The NV5 forum ( NV5 Geospatial - Help Forums - ENVI & IDL | NV5 Geospatial ) is now preferable as a source of IDL information.
