Anatomy of COVADIS geostandards
WHY
is it relevant to my needs ?
3 parts
A) Perimeter
B) Concepts
WHAT
data definition ?
C) Implementation
HOW TO
exchange or store my data ?

COVADIS geostandard qualities
Consensus
Pragmatism
an operational (ready to use) data structure
Extensibility
SDI a
Geostandard = kernel that can be enriched
Compatibility
SDI b
Kernel
Data models to prepare INSPIRE compliance

INSPIRE versus COVADIS
Risk management case
● Existing hazard areas
‒ Observations / Models
● 3 spatial features
COVADIS PPR (2012)
● PPR document +
regulations
‒ Hazard area
‒ Hazard area
‒ Regulation zone
‒ Risk area
‒ Vulnerable to the risk issue
‒ Vullnerability
● Vulnerability evaluation
● 2 usages / themes

Use and test cases

12
Dataset Validator : input parameters
1. Test name (useful for history)
2. Select standard
3. Add or remove directories of datasets
4. Launch the validation process

Dataset Validator : passed or not ?
Test (by name) with last date and result
Or load/delete older tests
Show detailed results

Timestamp
Elementary check
(rudimentary diagnostic : FATAL - enumerated value not allowed
Lets look at the xml rules...

Validator characteristics
✔ Central and local deployment
✗ Need to contact the template repository server
✔ Global an detailed but rudimentary reporting
(test run progress and results, timestamps)
✔ Including history
✗ No API, No workflow, No links to resolve errors
✔ Java implementation, with GUI
✗ Governance unclear

Conclusion
COVADIS geostandards should by design be
compatible with INSPIRE...
→ now starting to include explicit INSPIRE mapping !
●
Focused on implementation,
→ if necessary(?) compliant INSPIRE GML might be
produced by reverse mapping...
●
Geo-IDE Catalogue comes with interesting railing tools
(templates, standard metadata guidance, datasets
validator with standalone version...)
