Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>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.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>This data was collected using a drone carrying a digital camera in 2020.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>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.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>This data shows the areas in Ireland for which you can download photogrammetry data and contains links to download the data. </SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>This is a vector dataset.
