What is a standard?
“A standard is a document established by consensus
and approved by a recognised body that provides - for
common and repeated use - rules, guidelines, or
characteristics for activities or their results, aimed at the
achievement of the optimum degree of order in a given
context.”

Standard Standards Standards can be:
de facto standards: which means they are followed by
informal convention or dominant usage.
Very common in GIS
de jure standards: which are part of legally binding
contracts, laws or regulations.
Very rare in GIS
Voluntary standards: which are published and available
for people to consider for use
Need to be used more

Standards in Crime Mapping
If there is a need to support a range of data
from different agencies?
If there is a need to store date centrally and
access it from multiple systems?
If there is a need to run consistent spatial
queries and justify the results?
If there is a need to share the results?
