Geoloca'on Enrichment Tools
Geocoding Applica'on Stein Runar Bergheim Asplan Viak Internet AS
Overview What is it? Why it has been made? What it can do for you? How it was made? Step-‐by-‐step guide to a geocoding project? Exercises Ques'ons
• A tool to add geoloca0ons to exis0ng data • Can be used with any tabular data • Makes it easy to update original data source • Easy to plug into exis'ng work flows • Crowd sourcing-‐ready -‐ create with users for users

What is it?
Geography excellent for explora'on
I know what I am looking for and I know it exists in there
I am interested in informa'on that is relevant to a loca'on (a geo en'ty)
• LiQle XY metadata • XY only way to integrate ANY content • Enables map based presenta'on and explora'on • Opens up deep content • Metadata enrichment at source • Mul' level quality control
Why has it been made
• User management • Roles • Upload CSV text files • Mul' byte encoding support • Edit 'tle, XY, confidence or any aQribute • Filter by area, category • Add point, line, polygon • Lookup names sources
What it can do for you 1/2
• Lookup other map, loca'on providers • Add WMS layers to map • Select base map • Zoom, drag zoom and pan • Download geocoded data as KML, GeoJSON, RDF and CSV
What it can do for you 2/2
• A lot of people contributed to the specifica'on – LoCloud partners – Rough outline sketched during LoCloud kick off – Acerwards implemented by partner AVINET – Tested extensively by Riksarkivet
• Released under GPL and supported licenses
How it was made
A selec'on of LoCloud partners during kick-‐off meeitng in Oslo
Demonstra0on A step-‐by-‐step walk-‐through of a typical geocoding project
Geocoding Step by step
• Prepare file • Log in • Upload file • Create users • Assign access • Select data source • Filter data source • Select item
• View informa'on • Specify geometry • Select base maps • Edit aQributes • Specify confidence • Search for en''es • Use alterna've sources • Download data
Only requirement is a unique id and a
representa've name
Data sources
Top menu
Item list Geocoding form
Search databases
User management
Map, map tools
Search results
90+ = green 75+ = yellow 20+ = red < 20 = error
Map resolu'on also stored
Select from available
names sources
When clicking, will zoom to loca'on
Click to open with same extent
Download as GeoJSON, KML, RDF or CSV
Upload file
To sum up: step by step
• Prepare file • Log in • Upload file • Create users • Assign access • Select data source • Filter data source • Select item
• View informa'on • Specify geometry • Select base maps • Edit aQributes • Set quality • Search for en''es • Use alterna've sources • Download data
• Star'ng with X million non-‐geo records is difficult – Will take a long 'me to reach interes'ng sample size. – Easier to get help to improve than create from scratch
• Solu'on: combine automa'c and manual approach • First auto-‐enrich using available tools – List tools (AnnoCultor etc) – LoCloud Geocoding Tool for Desktop
• Then use LoCloud Geocoding Tool
Automa'c Geocoding
LoCloud Geocoding Tool for Desktop Involves poten'ally hundreds of database lookups per geocoded record Best suitable for desktop in order not to «break» or «overly stress» shared server infrastructure Adapted to specific na'onal datasets – key registries include: • Property • Address • Persons • Named en''tes
At the outset adapted for Norwegian registries but can easily be adapted to any other European/na'onal key registry
Thank you for the aBen0on (assuming that you paid any)
