Background

• A native Android Application • Developed voluntarily in Summer of 2017.• Utilises a subset of information from two datasets which are available now from data.gov.ie :

National Monuments Service (NMS)National Inventory of Architectural Heritage (NIAH)

Aim: To promote both Heritage & Culture in Kells and Open Data reuse in Ireland

Why a native app?

• Access to device hardware, i.e. GPS, text-to-speech engines, camera, microphone, voice recognition, AR, video, etc. • Faster execution time• Accessible by millions of users world-wide on the Google Play Store• Users are familiar with the user interface• Can store datasets on devices (performance/size trade-off)

Data AnalysisThe analysis of open datasets for data integrity and quality.

Data Analysis – What data did I need?

• Accurate location based data, in a format that could be used for the development of a native Android application. • “Good Data” – data that was accurate and required minimum manipulation and processing.• Data is of interest to the prospective end user (images, descriptions, classifications).•Common fields between both the National Monuments and NIAH datasets.• Accessible content which would allow intended text-to-speech functionality to operate effectively.

The National Monuments Dataset - National

• 155,328 records nationally• Available on data.gov.ie in multiple formats• Multiple co-ordinate systems (ITM, IrishGrid, WGS84 /lat-long).• Good quality data: No duplicate monuments• Good quality text, consistent, few anomalies• No reference to images in the dataset• 15,000 “redundant” records in the dataset• No “County” field•Multiple monuments with the exact same coordinate.

National Monuments Dataset - Meath

• 3738 records for Meath• Required removal of 86 “redundant” records• Manipulation of data required to extract Meath/Kells area data – possible opportunity to improve data by expanding on location data.• Issue with multiple townlands with the same name across the 6 electoral areas in Meath (e.g. Corballis – 7 instances)• It was possible to retrieve points within the Kells electoral area polygon using third party software.

National Inventory of Architectural Heritage – National

• 43,325 records nationally • Available on data.gov.ie in multiple formats (ARCGIS REST Api, CSV, HTML)• Multiple coordinate systems (ITM, IrishGrid, WGS84/lat-long)• High level of data integrity (county information descriptions & images available)• No duplicate latitude/longitude locations

National Inventory of Architectural Heritage – Meath

• 1132 NIAH records for Meath• High percentage of images for the database• Great descriptions• Similar issue with multiple townlands having the same name.• It was possible to retrieve points within the Kellselectoral area polygon using third party software.

Merging the two datasets

• Data cleansing resulted in 1269 records for the Kellsarea and the creation of a new dataset with the following information:

●Title●Townland●Description●Location (coordinates)●Image locations (url)●Category (i.e. National Monument or NIAH)

Things to consider as a publisher of data

• Be careful giving the exact same coordinates for objects. If possible displace the objects by a small distance.

ME020-043011- Souterrain 53.70738708 -6.304893067

Things to consider as a publisher of data

• Give as much location based information as possible to improve data integrity and reduce ambiguity (e.g. townlands, baronies, electoral divisions, electoral areas, etc.)• Publish multiple coordinate systems.• Both static and dynamic data are very beneficial.• Be mindful of who will be using your data who have limited resources/budget/technology (individuals, start-ups, citizens, etc.).• Support feedback and collaboration with those reusing your data.

Summary• Application can be applied to any area in Ireland that is of archaeological /architectural significance.• Supports responsible tourism, allowing users to explore sites on private lands.•Supports accessibility, allowing people to access information without leaving their homes.•Can be used as an educational resource for students/teachers.•Not dependent on cellular data•A product of Open Data!
