DLGV32 Pro is Global Mapper

Global Mapper was developed in conjunction with the USGS over 12 years ago. Throughout its history, the USGS has always been a key driver of the features and functions in Global Mapper.

USGS Digital Data Viewer: DLGV32 Pro

DLGV32 PRO = Global Mapper™ Evaluation License

If you're looking for DLGV32 PRO, simply download an evaluation copy of Global Mapper.

We are pleased to continue to work with the many departments of USGS and will do so for many years to come. As things have progressed we have decided to no longer brand the evaluation version of Global Mapper as DLGV32 Pro and simply point users directly to Global Mapper. DLGV32 Pro is simply that free evaluation version but if you work for the USGS, the agency owns a large number of full licenses so you should contact your IT or Department Manager for access to that license after downloading the evaluation version. Otherwise, Global Mapper may be used in an unregistered manner for simple file viewing if so desired.

Global Mapper supports direct access to the free online data in the USGS' Spatial Data Transfer Standard (SDTS) through the software interface.
