View large format images
Black and white images, for example, wirelines and seismic sections are scanned and output to a high resolution image format called TIFF (Tagged Image File Format) using CCITT Group 4 (G4) compression. Most scanned images in the DIGS® system can be viewed with standard imaging software, or converted to PDF format by a third-party software package incorporated into DIGS®.
However, some large formats (AO, or larger and tiled logs) may require a browser plugin to be installed in order to view the file directly in a web browser. If a plugin is required then it must be able to display TIFF files that use CCITT Group 4 (G4) compression. Many imaging software programs (such as ACDSee) and proprietary GIS packages (such as ERDAS ER Mapper) can be purchased and installed to view large format TIFF images.
If you don't have proprietary software to read TIFF files then there are many open source software imaging programs and free proprietary viewers. The Department does not endorse or offer support for any of these software packages. Some of the free plugins available online include:
