4. Outline
 Why are we talking about Validation and QC ?
 What can we check?
 Schema
 Attribute Values
 Geometry
 Etc.
 Validation Workflows on FME Server
 Partner Examples

5. Why are we talking about this?
 Bad data costs time, money and even lives.

6. Why are we talking about
Validation and Quality Control?
 FME and FME Server are powerful tools for
checking data and providing feedback
 Many partners, integrators and users use FME
today for Validation and Quality Control

7. What can we check?
 Schema
 Feature Type Name
 Attribute Present
 Attribute Names
 Attribute Data Types
 Coordinate System

8. What can we check?
Schema Checking – Key Tools
 Schema (Any Format) Reader
 FeatureTypeFilter
 StatisticsCalculator
 AttributeClassifier transformer
 XMLValidator Transformer
 JSONValidator Transformer

9. What can we check?
 Attribute Values
 Values exist
 Data Type (numeric, alpha etc)
 Value within in range
 No duplicates

10. What can we check?
Attribute Values – Key Tools
 Tester and TestFilter
 AttributeClassifier
 AttributeRangeFilter & AttributeFilter
 NullAttributeMapper
 Matcher
 DuplicateRemover
 StringSearcher
 StatisticsCalculator

11. What can we check?
 Geometry 2D and 3D
 Intersections
 Orientation
 Duplicate Vertices
 Missing Surface Normals
 Invalid Solid Voids
 etc

12. What can we check?
Geometry Checking – Key Tools
 GeometryValidator (12 tests and counting)
 Detection and repair
 old transformers bundles in eg Self-Intersector
 GeometryFilter
 Matcher
 SpatialFilter (Sweco example)
 SliverRemover & SpikeRemover
 AreaCalculator & LengthCalculator
 OrientationExtractor

13. Workspace Example

14. Validation Workflows on FME
Server
 Submit data via email, upload, directory watcher,
scheduled task
 Provide report or results via email, form, data
download, PDF

15. Validation Workflows on FME
Server

16. Partner Validation Examples
#1 Axmann GeoChecker
1. Users upload data
2. Workspaces Check Schema, Geometry, Attributes
3. Email sent with PDF Report and Bad Data in AutoCAD

17. Partner Validation Examples
#1 Axmann GeoChecker
Detailed Reports & AutoCAD File of Errors

18. Partner Validation Examples
#2 Veremes - Qualigéo
 Generic Approach to avoid “Chamber of Horrors”

19. It's easy
Constraint FME tool
Geometry GeometryValidator
Spatial Relationship SpatialFilter/SpatialRelator
Integrity Constraint Feature Merger
Topology
Attribute Domain String Searcher
Statistic Statistic Calculator
Schema Schema reader
Unique Key Duplicate Remover

20. It's complicated

21.  Hyper generic workspace
• 1 unique workspace to validate all formats, all
data models, all constraints...
 Using an external description of the data
model and constraints
Solution
