Backround
－ Geostat 1A,1B and 1C projects (2010-2014)
– Creation of national population 1 km² grid data sets
– Harmonisation of
• The grid net
• Population data by 1 km² grids
– First attempts to describe the production process
－ Geostat 2 (2/2015) ->
－ Premilinary ”Framework for Spatial Statistics”
• GSBPM – Generic Statistical Business Process Model (5.0)

The GSBPM describes and defines the set of
business processes needed to produce official
statistics.
It provides a standard framework and
harmonised terminology to help statistical
organisations to modernise their statistical
production processes, as well as to share
methods and components.

Processes of spatial statistics have also
been described earlier …

－ Phases were identified independently
– the GSBPM was not used
－ Interpretation of the process flow
diagram is difficult – a certain level of
abstraction would be needed
－ BPMN (Business Process Model
Notification) was not used
－ The value of the work was to identify
tools and instructions needed
during the process
Objectives of Geostat 2
- and SF tasks
Geostat 2, Work Package 1:
Model for a point based administrative geospatial reference
framework
Stat FI:
－ Aims to create a national model
– Define a role of spatial data in the statistical production
process and using GSBPM describe a general process, also
define connections to other supportive systems
(such as metadata, classifications, quality descriptions)
7
– Test the model: INSPIRE data product (demography)
－ The model will be evaluated by others (AT, PT at first)
First questions and findings
－ What are the targeted processes?
– Recognition of the key processes
• Relate to spatial statistics
• Relate to map data
－ What is the ultimate outcome we aim at?
– A preliminary model was illustrated
－ What should be the level of process descriptions
in order to achieve a general model ?

Premilinary
”Framework for Spatial Statistics”
- To introduce to the GSBPM
- To identify key processes
- Inspired us to continue
the work
- Good feedback !!

Modeling of processes – target processes
－ To start - perspective (traditional Geostat topic):
Inspire, Demography - Population distribution
－ Identification of two processes:
– Production of “Grid Net for statistics (1 km x 1 km)”
– Production of “Spatial Statistics”
– Production of statistical units (not yet, but most likely needed)

Modeling of processes
Story Mapping method:
http://www.slideshare.net/SteveRogalsky/user-story-mapping-in-practice
1. Writing down free cognitive associations (tasks) of the process
2. Classification of notes and identification of phases + completion by phases still missing
3. Identification of GSBPM phases + completion by phases still missing
4. Creation of the model + recognising actors

Experiences
－ The level of abstraction that is essential for understanding the
process must be chosen (as high as possible)
– Helps identify similarities between processes
－ The process itself and the supportive sub-processes have to be
distinguished
－ After finding the right GSBPM phases some missing phases
could be detected
－ Some GSBPM phases must be repeated during the process
Acceptable from the point of view of GSBPM instructions
e.g. In process phase 5 - 5.1-5.8
• Actions in order to produce statistical data
• Actions for combining statistical data with spatial boundary data

Experiences
－ Process phases are quite easy to fit to the GSBPM model!
– The GSBPM model descriptions do not contain any
description or reference to spatial data A GSBPM pro is therefore needed
－ Use of GSBPM requires raising the level of abstraction when
interpreting phases
– Suggestion: could the abstraction level be higher already
in phase descriptions of GSBPM?
－ A big surprise: the method is very fast!

Lessons learned: GSBPM ”rules of use”
1) Modelling itself is not the target
– to understand the process is
2) Describe the process as it is
– after selecting the level of
granularity
3) Apply the model
– use it as a tool

Follow-up
Production process of spatial statistics in SF
– A synthesis
A point based administrative geospatial reference Framework
is the main goal
－ The process model stands as a base
– Identify connections to other systems
(such as metadata of data and processes, classifications etc.)
– Identify the actors (stakeholders involved)
– Test the process for production with an INSPIRE compatible
data product (Demography)
－ The model will be evaluated by others (AT, PT at first)
