GeoArchive

GeoArchive has been made by our partner Affecto in Estonia. It manages the whole survey data process aiming that: !  Map and/or network data is

"  up-to-date "  accurate "  reliable "  according to rules "  everything you might wish for …

4

GeoArchive is meant for

! Local authorities and companies engaged in geodesy

! Gathering and archiving geodetic surveys and distributing map data based on geodetic surveys to users of GeoArchive

! GeoArchive includes processing of: "  geodetic plans "  executive survey drawings (as-built surveys) "  cadastral unit surveys "  data management jobs

5

Two implementations in production

! Elion (TeliaSonera in Estonia) "  workflow to manage network updates "  extract-translate-load process "  data model and mapping rules

! City of Tartu "  to manage survey process and data "  workflow to manage map updates "  based on Estonian national standards

6

Components of the solution

! Workflow management ! Technical processing

"  FME from Safe Software "  Microstation DGN V7 and V8 "  Autodesk DWG 2010 and earlier versions

"  mapping rules are held in the database "  validation tests use the same rules

! Filtering approach, only needed data ! Auditing, everything is tracked ! Export on demand into CAD files

Feedback to fix data

Database of real world objects

! Managing attribute data and geometries of different classes of objects: "  buildings "  roads (road class, roads, road sections) "  water "  geodetic marks "  networks "  etc.

! Data model is dynamic, all descriptions of object classes are stored in database

9

Some common details of the implementations ! Processing of geodetic surveys and some other

map data management jobs "  initiation, accepting, rejecting, registration etc.

! Uploading files of geodetic surveys (FME) "  Microstation DGN "  Autodesk DWG

! Validation of uploads files (FME) "  validation rules are based on Estonian legislation "  validation rules are described in FME "  easy to modify for local needs with FME

10

More common details of the implementations ! Uploading object geometries from files to database

‘middle layer’ "  objects in the ‘middle layer’ are not visible for all

! Correction of uploaded geometries in GeoArchive UI ! Surveys map data is made public on final

acceptance of the survey "  browsing the map (public data) in GeoArchive map

window "  downloading surveys uploaded files "  downloading an extract of a map data from specified

area (FME) 11

Benefits

! Increased processing speed, from 3-5 weeks per project to 2-3 days

! Traceability, increased reliability

! Consistency throughout the organisation

! Workload balancing

18

Another benefit is a view to multiple data sources

19

Lessons Learnt

! Standardisation is the key to success ! Automated quality checks ! Shallow acceptance curve, to put it nicely (normal

resistance against anything new…) ! Constant monitoring of the entire process chain ! Bills paid only after documentation has been

accepted
