Next Generation National Mapping

Lorraine McNerney, CIO

Irish National Mapping Agency

• Established in 1824

• State Body since 2002 under the OSi Act

• Under the Dept. Housing, Planning &

Local Government

• 230 staff (30% reduction since 2008)

• HQ Phoenix Park, 6 regional offices

Ordnance Survey Ireland Act, 2001

Mandate includes:

• To create and maintain for the entire State mapping and related geographic

databases

• To encourage and promote the benefits of the use of the national mapping

and related databases

• To develop products, services and markets to meet national and user needs

• To advise on policy and practice of survey, mapping and geographic

information and on the development of national spatial database

infrastructures

• To represent the State at national and international level on matters

relating to mapping and geographic information

OSi Strategy 2016 - 2018

To create, maintain and provide the State’s

definitive mapping and geospatial information services

to support citizens, business and government.

Mission

The national providers of trusted, maintained

geospatial data and platforms to ensure the State’s

location data is easy to find, share and use.

Emergence of new ‘Disruptive Technologies’

Our key challenges

• Compatibility with the Internet Of Things

• Ability to provide greater value to our customers (adaptability, flexibility,

standardisation, better mapping intelligence)

• Ability to develop new products and services

• How to take advantage of emerging technologies

• Optimising the bottom line (removing operational inefficiencies and

maximising production automation)

Fundamentally, how do we remain relevant

and provide organisational sustainability?

A new approach to National Mapping

We developed two new concepts:

1. A single source of geographic truth (one authoritative digital map).

2. ‘National Mapping-As-A-Service’.

Spatial Data Collection and Management

To:

� Unique Real-world Object ID referencing

� URI’s and Spatial Linked Data

From:

� Latitude / Longitude

� Easting / Northing

Traditional spatial referencing has changed

Prime2 – ‘Concepts’

• Skin Of The Earth Objects

• Superimposed Objects

• Links objects using persistent ID’s

• Form & Function object classification

• Segmentation & Connectivity

• GDF1 & GDF2 road modelling

• Z-Order Property

• Sites & Locales

• 3D data storage (CityGML LOD2)

• Sites & Locales


Form

Physical form of an object as it exists in the real world

i.e. Building, Pylon, Field, River, Lake

Function

‘Use’ or ‘Purpose’ of an object in the real world

i.e. Residential, Army Barracks, Electricity Supply, Agricultural, Reservoir









• Sites & Locales

• 3D data storage (CityGML LOD2) Full geometric network connectivity

on Roads, Rail and Rivers

• Sites & Locales


Sites

Points of interest with known boundaries

i.e. Hospitals, University, Golf Course

Locales

Fuzzy boundaries where the geographic entity is undefined or subject to interpretation

i.e. Mountain Range, Bay, Town









• Sites & Locals
