The proposal of the GSBPM model improvement in terms of spatial component

of the statistical production process

At Statistics Poland a comparison between the GSBPM and the national process model has been carried out. The practical implementation of relevant processes relating to spatial data and mapping them with GSBPM model showed that the important areas are not included in the model, although they are important and necessary in the actual production process. By indicating these areas, the potential shortcomings and imperfections of the GSBPM model were diagnosed. The analysis revealed shortages of the GSBPM model, which essentially concerned statistical data spatialisation aspects from the stage of designing the data collection, geocoding, analysis and providing spatial characteristics of statistical products.

Therefore, Statistics Poland suggest that the current GSBPM model should be modified by adding the following four new sub-processes:

• Phase 2: subprocess "2.5a Design geocoding frame, sample & data collection";

• Phase 4: subprocesses "4.1a Geocode frame & sample" and "4.3a Geocode collection";

• Phase 6: subprocess "6.2a Prepare spatial analyzes & maps";

• Phase 7: subprocess “7.2a Manage spatial analyzes & maps using GIS"

The introduction of above sub-processes would enrich the model with a spatial component of the statistical production process, which will allow a better understanding of spatial data as well as its role and place in the statistical production process and the standardization of methodologies merging statistical data with spatial data. This issue is still poorly perceived by the statistical community and is still in the early development phase. For obvious reasons spatial elements could not be fully taken into account when constructing the model. The introduction of the proposed changes in the GSBPM model would contribute to strengthening the position of geospatial statistics in the statistical production process.

Finally, the updated version of the graphic GSBPM model could look as follows:
