-Class trip to the River.
-Set up Builders Level.

My Contour Plan results.

Today we went down to the river,We were split up into four groups of six.The equipment we had was,A Sopworth Staff,Builders Level,Tripod,Dazzle(Spraycan),and a 30 metre long tap measure.A member in my group sprayed a cross to represent the start of the grid.We set up the Builders level on the tripod and got it level.We sprayed the increments of 5 metre lines inbetween the 30 metre line which added up to six squares, after that we did the 345 to get an accurate line at 90 degrees.Then we replicated what we had done earlier.After we had the grid set up we got the Staff out and I used the builders level to gain the measurements using the line of collimation in the sight of the level.After we had finished that practical activity we headed back to UCOL.Matt showed us how to construct up a contour plan which is mainly used by achitects.The contour plans basically show how rough the terrain is.
