We were asked to survey this field so our client could better understand the layout of the pathways versus the trodden desire lines, the shape of the river, how it moves through the area, for current and future reference and the general topography of the whole area. Topographical measurements are displayed in colour gradients, as seen in the picture to the right, to give a clear, easy to read and immediate idea of the shape of the terrain.
You can see from the pictures, notes, lengths and area measurements were taken and saved with the mapped image to help explain issues and record data.
Image 4 demonstrates the difference in resolution between Google Earth and our photomosaic maps. Our maps are laid over Google Earth's images to clearly show true orientation and give a wider, more complete picture.
We also took some close up stills of a tall tree to check its integrity so as to make sure it wasn't an immediate, obvious danger to the public. This obviously saved our client the risk of sending staff up for a close inspection, the danger involved with working with ladders and the time and expense in erecting scaffolding on an uneven, soft surface. The images could also be passed around amongst colleagues or forwarded to contractors to aid in the explanation of issues. They can also be kept on file to monitor the problem area over time.
