experience of CNV records
(small one class only GIS national
standards)
produce geographical standards adapted to the
needs of the two ministers

Anatomy of COVADIS geostandards
A) Perimeter
B) Concepts
C) Implementation

is it relevant to my needs ?
WHAT
data definition ?
HOW TO
exchange or store my data ?

INSPIRE versus COVADISRisk management case
● Existing hazard areas‒ Observations / Models
● 3 spatial features‒ Hazard area
‒ Risk area
‒ Vullnerability
● Vulnerability evaluation
COVADIS PPR (2012)● PPR document +
regulations‒ Hazard area
‒ Regulation zone
‒ Vulnerable to the risk issue
● 2 usages / themes
III.8Land Use
III.12 Natural Risk zones

Validation ToolUse and test cases
1303 juin 2016 KEN Validation Workshop
Dataset Validator : input parameters
1. Test name (useful for history)2. Select standard
3. Add or remove directories of datasets4. Launch the validation process
1403 juin 2016 KEN Validation Workshop
Dataset Validator : passed or not ?
Test (by name) with last date and result
Show detailed resultsOr load/delete older tests
Timestamp Elementary check
(rudimentary diagnostic : FATAL - enumerated value not allowed

Lets look at the xml rules...
1803 juin 2016 KEN Validation Workshop
The same, more human readable !
1903 juin 2016 KEN Validation Workshop
Complete (manual) error resolution
2003 juin 2016 KEN Validation Workshop
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...)
