Gazetteer of Australian Historical Places, v3.0. November, 2021
This upgrade has involved some major revisions to the database structure and core functionality. It's important to get this right as GHAP is a foundation on which other things will be built. We expect to carry on through 2022 and beyond (grant pending). If the grant doesn't come through we intend to find a way to carry on because of TLCMap's great potential and clear, wide ranging benefits to researchers and the public. We are exploring industry and institutional partnerships. With this GHAP upgrade in place, other enhancements, features and visualisations can follow in more rapid succession.
policy for Unique IDs of records in TLCMap established.
better handling of 'title' and 'placename' ambiguity.
more forgiving handling of dates.
improved data structure for layer metadata.
addition of 'content warning' field.
improve register to create a login workflow for 'least surprise'.
addition of 'type' for broad categorisation to ease use in future.
better handling of 'Extended Data' (extra non-standard columns in spreadsheet) in the database and in export and visualisation.
better handling of the important 'Linkback' URL.
improvements to 3D viewer.
consistent and complete handling of download and web services for search results and layers as CSV, KML or GeoJSON.
better layout of search results, to avoid scrolling of wide tables.
better nomenclature such as the term 'layers' to reflect the entire purpose and name 'TLCMap', instead of 'datasets', Gazetteer of *Places* not placenames.
more forgiving handling fixes to CSV import, handling issues with dates, multiline cells, non UTF8 CSVs.
link individual places to Trove searches in 'Visualise' drop down.
migration from MySQL to Postgres for compatibility with UON, use of PostGIS, and future seamless integration with Spatiotemporal Metrics.
miscellaneous bug fixes.
revised documentation, including simpler beginners introduction.
Some Priority Enhancements to Follow:
Better UI for adding and editing of individual items in the layer, within GHAP.
STMetrics Integration for one-click statistics and cluster analyse (or maybe 2 or 3 clicks TBH).
Code snippet for embed map in another web page.
Handling overlapping dots on the map.
Download and re-upload updated data to preserve persistent ids, instead of deleting and creating new ones.
Some Aims for the Future (pending funding)
add multiple layers and/or search result to a single map.
integration and enhancements of prototypes, such as Recogito, cyclical widgets, STMetrics, Ordinal visualisations, etc.
more ingest of cultural collections and library materials.
mining text with natural language processing.
mapping across media and collections.
Hotspot analysis prototype developed
Extensive use case testing for data ingest
Gazetteer migrated to Postgres for compliance with UON IT, and to make PostGIS available, in particular to close integration with Spatiotemporal metrics.
Improvements to Quick Coordinates.
Problems with Recogito were encountered during the launch. About 1 month of development time is required to polish our enhancements for contribution back to the main branch. Recogito withdrawn from service till this can occur.
Spatiotemporal metrics prototype functional, but withdrawn until it can be integrated with GHAP. STMetrics requires data upload to process, which should happen directly into GHAP, instead of 2 places. This has the added benefit that those wanting metrics also contribute a layer at the same time. GHAP migrated to Postgres to enable this.
Heurist deployed their UI enhancements.
Gazetteer User Contributions
Temporal Earth Integration
Spatiotemporal Metrics - basic statistics
Spatiotemporal Metrics - cluster analysis
Gazetteer of Historical Australian placenames launched.
Processed ~300,000 records of which only approx. 1/3 had well formatted coordinates. We extracted coordinates from free text fields for ~200,000 records.
