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.<\/SPAN><\/SPAN><\/P> Knowing this time measurement scientists are able to create topography maps.<\/SPAN><\/SPAN><\/P> 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 on 25th March 2015.<\/SPAN><\/SPAN><\/P> This data shows the areas in Dublin for which you can download LiDAR data and contains links to download the data. <\/SPAN><\/SPAN><\/P> This is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).<\/SPAN><\/SPAN><\/P> The LiDAR coverage is shown as polygons. Each polygon is 2000m by 2000m in size and holds information on:<\/SPAN><\/SPAN><\/P> Location - County the data is located in.<\/SPAN><\/SPAN><\/P> Data Provider - Who provided the data.<\/SPAN><\/SPAN><\/P> Data URL - A link to download the LiDAR raster data in 2000m by 2000m sections.<\/SPAN><\/SPAN><\/P> General Comment - Licencing details.<\/SPAN><\/SPAN><\/P> Published Date - Date the data was published online.<\/SPAN><\/SPAN><\/P> Data Owner Identifier <\/SPAN><\/SPAN>\u2013<\/SPAN><\/SPAN>Data owner.<\/SPAN><\/SPAN><\/P> Data Surveyor <\/SPAN><\/SPAN>\u2013<\/SPAN><\/SPAN>Data collector.<\/SPAN><\/SPAN><\/P> RMS Error - Root Mean Square Error in the z.<\/SPAN><\/SPAN><\/P> Capture Date -Date data was captured.<\/SPAN><\/SPAN><\/P> Resolution - Horizontal resolution of the data - grid cell size.<\/SPAN><\/SPAN><\/P> Data Originator <\/SPAN><\/SPAN>\u2013<\/SPAN><\/SPAN>Organisation the data originates from.<\/SPAN><\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
