Best Practices for OPUS Share Photos

Best:

•Clear, distinct close up and horizon photos•Stamping clearly visible•Equipment shown, location clear, mark distinct

Worst:

•Equipment blocking stamping•Photo is blurry, stamping is difficult to read•Location of mark not clear in horizon photo

How Do I Send the Data to NGS? • 1) Bluebooking of GPS surveys

– Difficult to do! Getting better with Beta OPUS-4

• 2) OPUS-Share– Easy to do!

Always sandbag your tripod! …

• constrain adjustments to CORS, local control, elevation control

• publish results to NGS database (optional) (Try Beta OPUS4)

• OPUS-Project works with 2 or more hours of data

What is OPUS Projects?OPUS Projects offers Web-based access to simple visualization, management and processing tools for multiple marks and multiple occupations. Some of its advantages include:• Data uploading through OPUS.• Processing using the PAGES software.• Graphical visualization and management aids.• Supports bluebooking with Beta OPUS-4 version.

OPUS PROJECTS• Allows user to observe multiple marks, using

multiple receivers, in multiple sessions• Send it all to OPUS PROJECTS• Calculate sessions and perform an adjustment tied to

NSRS• Using a Web Browser• Useful as a project management tool, independent

check on existing workflow, or stand-alone utility.• Unlike other OPUS flavors – training required.

We still need surveyors. We hope OPUS Projects can help, but it can’t do your job for you.

• Follow your project’sspecifications.

• Use best practices andcareful field procedures.

• Select permanent marksof public interest.

• Good coordinates come from good data. http://gis.larc.nasa.gov/
