DESCRIPTION
This presentation describes GeoArchive, a survey data management system based on a PostGIS/PostgreSQL database, and how FME is used to upload, validate and download geodetic survey information for it. See more presentations from the FME User Conference 2014 at: www.safe.com/fmeuc

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

Bills paid after

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

Accepted data. Colored to separate it clearly.
Rejected data. To be sent back with an error report

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
