Validating Gigamaps and SOD work

By Birger Sevaldson

 

The methodology of Gigamapping and the supporting methods and techniques do have several ways of validating the work.

However, this is not enough to make sure the maps are valid. Additional attention needs to be taken.

The different modes are listed and described here.

Gathering information: Make sure you check and double-check information. Information given by singular informants should be triangulated by asking others or by other type of data. 

Framing: The Gigamapping process is super for framing the project and research area with its flexible boundary critique. The strategy of first map out without filtering out seemingly irrelevant issues ensures one covers a wider territory than what one assumes form the start. To withdraw from these territories after checking them, to draw a relevant boundary in an informed way is key to this process. Another effect is that one becomes a bit knowledgeable about the bigger field at hand. Reframing by enlarging or shrinking the boundary during the process ensures a reflected development and boundary critique

Coding of information value: We advise to use color or font coding or annotations to target, describe and rank information quality on the map. Such coding can distinguish between the a priori given, hard facts, well triangulated qualitative data, Common knowledge, interpretations, informed guestimations and sheer assumptions. Since the information is coded on the gigamap it is contextualized and situated. Therefore it is possible to analyse the importance of the information and if it needs improvement. The coding can then be used to refine and triangulate information, that is crucial.

ZIP analyses: The Zoom in the ZIP analyses helps to improve resolution of information on the map and to distinguish between less important areas to zoom into and those that are crucial. Additional information gathering and interpretation has to be made.

Expert co-designing: Building expert networks is central in SOD. The experts should be knowledgeable about different types of information. For example, experts from health care should be interpolated with expert patients.

Back-checking: The information gathered is always situated on the Gigamap. When starting to work with design resolutions and interventions one can back check in detail how the suggestion fits the research and where it leaves uncertainties that require additional investigations.

Together these different modes, if conducted in a good manner, construct the evidencing of GIgamaps.
