Description: Photogrammetry is a remote sensing technology, i.e. the technology is not in direct contact with what is being measured. From drone, aeroplane or helicopter, photographs are taken. Multiple overlapping photographs of the ground are taken. Precise measurements from the photographs can be taken to create topography maps.This data was collected using a drone carrying a digital camera in 2019, 2020 and 2021.A software package was used extract points (X,Y,Z (x & y coordinates) and z (height)) from the photographs. The data is then converted into gridded (GeoTIFF) data to create a Digital Surface Model of the earth.This data shows the areas in Ireland for which you can download photogrammetry 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 photogrammetry coverage is shown as polygons. Each polygon is 2000m by 2000m in size and holds information on:County - County the data is located in.Location - location nameData URL - A link to download the raster data in 2000m by 2000m sections.Data Licence- Licencing details.Data Owner –Data owner.Data Surveyor –Data collector.RMS Error - Root Mean Square Error in the z.Capture Date -Date data was captured.Resolution - Horizontal resolution of the data - grid cell size.Data Originator –Organisation the data originates from.
