Survey work

Last Wednesday a small band of intrepid project members made it out to the site to do some further survey work.

One of the aims of the project is to generate a topographical map of the area we have been investigating. The fieldwork part of the survey is undertaken using a Total Station, a measuring device similar to an old fashioned theodolite, but an electronic one that can ‘log’ point in 3 dimensions in its memory.

The data gathered in the field can be downloaded to computer and in a GIS (Geographical Information System) programme we will be able to re-flood the lake to different levels in order to see where the lake margins lay in different time periods. As it happens this year nature has been doing a very good job of re-flooding the landscape itself. I am not sure if there is more water standing on the ground than in June, but it certainly remains deep. It is also more of a problem now as we are looking to map the lower lying areas as well as the sites, which lie a little higher.

Fingers crossed we will make it out a few more times in the next couple of weeks and gather more data. Once we have enough to process we will upload our first maps here. So keep looking by,
