cartographic challenges
CCRI Gloucester University

Dr Scott Orford WISERD, Cardiff University
Overview
• Background to research
• Geo-tagging interview transcripts
• Geo-visualization and mapping
• Spatial metrics
• Some emerging issues
• Use of QGIS in localities research
• Conclusions
WISERD
WISERD
• Major investment in research infrastructure in Economic and Social
Sciences across Wales
• Major innovations in qualitative, quantitative and mixed methods
• Establish flexible and integrated sets of data relating to Wales
• Strategy for generating research grant bids and sustainability
• Links with WAG, ONS and Local Authorities across Wales
• Links with Other Centres and Programmes in Cardiff
Emerging research
• Collaborative Qualitative GIS research project involving both GI professionals and qualitative researchers from backgrounds with little association with spatial literacy or mapping
• Attempt to understand the different geographies that policy makers make use of in their day-to-day work
• Context of Welsh devolution where some policy areas devolved to WG some still remit of Westminster
• Provide empirical support to theoretical concepts of relational space (Jones, 2009)
• GIS augmented traditional qualitative analytical methods

Interviews
• In-depth interview 120 stakeholders across 3 localities who have links to 8 policy areas
Crime, public space & policing Education and young people
Language, citizenship & identity Environment, tourism and leisure
Health, wellbeing and social care Economic development and regeneration
Housing and transport Employment and training
Transcipts
• Interviews recorded and transcribed by professional company
• Analysed in CAQDAS package (Atlas.ti)
• Parsed through qualitative meta-data generator using Web Services to geo-tag places and semantically tag words

data mapping
(place names
in interview
transcripts)
• Place names geo-tagged with page, line number and word number in transcript
• Also, all transcripts manually geo-tagged to allow success of automated geo-tagging to be evaluated
Geo-tagging
• Place names in the transcripts identified and extracted with page and line number
• geo-tagged to a single point using the OS 1:50,000 scale gazetteer

Problems of geo-tagging
place names (Southall, et al. 2011)
• Identifying place names in transcripts
• Place name spelling mistakes in transcripts (esp Welsh place names)
• Vernacular names with no official geography
• Confounding place names with different geographical features
• Multiple places with the same name (geotag)
GeoVisualization
• Geo-visualization is an important aspect of Qualitative GIS and a function that has been used to justify and promote its use (Knigge & Cope, 2009)
Conventional dot mapping using proportional sized circles for each place mentioned in the transcripts
A kernel density surface of the places mentioned in the transcripts of all the stakeholders from the local authority of Ceredigion
Centrographic Maps where point locations are replaced by statistical summaries of the locations such as standard deviational ellipses and mean centres
Spatial Metrics
• GIS allows the construction of basic spatial metrics
• Can augment quantitative measures generated through analysis of coding of interview transcripts
• Provide support for discursive narratives of geographical themes in transcripts
Percentage of places mentioned in each Local Authority according to the local authority of the
stakeholder interviewee

Discussions • QGIS negotiate issues such as data sharing, confidentiality,
disclosure and what can and cannot be presented to people outside of the team.
• Added value to conventional qualitative analysis
• Value of the spatial metrics that could not be created in the CAQDAS
• Some spatial patterns uncovered in CAQDAS analysis but only treated discursively
• Cannot analyse or interpret maps / spatial metrics in isolation of transcripts or context of interview -
complimenting qualitative research (mixed methods) • What is relevant in the geo-tagged data

Future Research
• Analysis of automated geo-tagging software
• Development of non-disclosive cartographic techniques
• Further analysis of maps and spatial metrics and how they can be interpreted meaningfully in the context of interviews
• EQUALISA - transcript mapping and exploratory tool
