DATELINE
Database in digital format
PMWG Meeting, Luxembourg, 24/25 April 2003

2. Database Weighting on Person Level
Is consistent set of long-distance passenger travel information
Database covers European Union and Switzerland
Delivers coded data and derived information
Describes long-distance mobility at several levels of detail
Is delivered in form of relational database, exported to text files.

4. Weighting on Person Level Coding & integration
Work carried out by many partners from various European countries
Coding tools prepared by the project (Coding book, Collect It, Geocode It)
Coding and integration started concurrently with the data collection process
Error correction process performed in parallel with coding
During post processing calculated variables were derived (weights, expansion factors, NUTS zones, aggregate values)
Survey organisations responsible for coding and geocoding (good – place spellings, phone back)
Coding tools before field work starts, since many org. allow ASCII, coding book compliant, instant error checking,
Four scheduled intervals, two stages, for each survey organisation separately, need more! Feedback on errors provided.
Corrections together with data, always complete database, SN is responsible for data until error free
At the data centre all partial databases integrated, several variables calculated for following processes (BOKU, TIS), import G,EF, export

5. Weighting on Person Level Geocoding
Two basic reasons – distance calculation & spatial distribution
Project requirement about spatial distribution was NUTS 1
Place name (town, village, ...) coordinates are sufficient
GEOnet Names Server, National Imagery and Mapping Agency's (NIMA) + US Board on Geographic Names
ID as reference to the list of places is stored in the database
During data integration and post processing, global coordinates and NUTS codes were assigned to each place

6. Weighting on Person Level Structure and format
Database is available in integrated form containing information from all countries. It is also available on country basis.
The exports were produced from the relational tables of the MS SQL database system. Each relational table is extracted as a separate file.
Example:
File: Households.txt
Content:
First line: ”HHID”;”HH_PERSC”;”HH_U5”;”HH_5_14”; etc.
Other lines: ” ”;”3”;”1”;”0”; etc.
” ”;”2”;”0”;”1”; etc.
etc.
HH state
Participants – additional dimension HH journeys + P journeys
