Questions that real time services can help answer
How much publicly available data is there in the area we’ve
targeted?
What kind of sample data is there in the area we’ve targeted?
Do the kinds of geochemical anomalies we’re looking for show up
in existing data?
What is the quality of the data that we could use?
All without going to the surveys
All based on the latest available data – no checking for “releases”

Practical scenarios and benefits for companies
Ground truthing existing maps and data samples in real time
Analysis in the field - find something interesting – wanted x data set
to compare but left it back at the office
WFS is queryable so that most recent data for any given area can
be acquired without having to download entire data sets – useful
over limited bandwidth capacity
Burden on companies to manage survey data reduced, if not
removed
Re-use of any tools and techniques between jurisdictions –
increases efficiency of both mining and exploration companies and
software developed by SMEs
