Abstract:  LiDAR (Light Detection and Ranging) is a remote sensing technology, i.e. the technology is not in direct contact with what is being measured. From satellite, aeroplane or helicopter, a LiDAR system sends a light pulse to the ground. This pulse hits the ground and returns back to a sensor on the system. The time is recorded to measure how long it takes for this light to return. Knowing this time measurement scientists are able to create topography maps.LiDAR data are collected as points (X,Y,Z (x & y coordinates) and z (height)). The data is then converted into gridded (GeoTIFF) data to create a Digital Terrain Model and Digital Surface Model of the earth. This LiDAR data was collected in 2011.This data shows the areas in Ireland for which you can download LiDAR data and contains links to download the data. This is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The LiDAR coverage is shown as polygons. Each polygon is 2000m by 2000m in size and holds information on: the location, data provider, owner, licence, published date, capture date, surveyor, RMS error, resolution and a link to download the LiDAR raster data in 2000m by 2000m sections.

Purpose: LiDAR is important as it generates accurate measurements instantaneously. Knowing the height of the Earth’s surface is important for a number of reasons. Landslides, small fault scarps, and other geologic features that are difficult to spot visually in the field or on aerial photographs can often be clearly shown on LiDAR images. LiDAR data helps detect where flooding might occur. The risk of rivers flooding is linked to factors such as: climate, the material that makes up the banks of the stream, the channel slope and the topography. The LiDAR (topography) data enables more accurate mapping of where the water will flow. LiDAR data helps planners to assess where to place new buildings; knowing the height of buildings, LiDAR can determine where shade will occur and where best to place solar systems. LiDAR data helps foresters to measure the height of trees in a forest and hence estimate the volume of timber. LiDAR data helps archaeologists to find archaeological sites. Remains of buildings and other sites can be almost impossible to spot with the naked eye. LiDAR can pinpoint tiny surface differences that reveal small sites like graves or big ones like sunken cities.

Lineage:
Lineage statement: 1. A national vector dataset for Ireland is produced using QGIS. 2. The “Create grid” tool within QGIS was used to create the dataset. 3. Each polygon within the grid is 2000m by 2000m 4. The LiDAR data are clipped to each of these polygons within the grid 5. The data can be downloaded on a polygon by polygon basis 6. The index was cleaned using SAFE FME software and imported into an ArcGIS Enterprise geodatabase using ArcGIS PRO. Links to GeoTIFF packages were included as URLs. This was then published as a Map Service and added to ArcGIS Portal to be included in the Open Topographic Viewer. 7. Metadata was added to the data using Catalog and conforms to GSI Standards based on ISO and INSPIRE.
