Finishing up Herbert Run

Saturday April 21st  , Shelby, Dana and I went out to Herbert Run and were able to get a lot done in in the field. We were able to set a decent amount of control points as well as make progress during the stake-out by obtaining roughly 8 more points. The points we were able to get were the ones on the far Eastern edge of Herbert Run 168-175. This leaves us with about 8 or so points left that need to be mapped out and I am convinced that with Dana's help today and a little help Friday that I will be able to complete the Survey either Saturday or Sunday at Herbert Run. Then next week I can do the complete Survey for The Knoll.

This data collector is helping a lot. At Landesign Inc. the data collector I used was no where near as nice as this one is. It can connect to the internet, which could make stake out really convenient. As displayed in the picture on the left the Trimble actually pulls up a complete map of the Survey that I will do. The points you see on the screen are the ones that I have loaded in. It also has my control points which you can see towards the top left of the screen as point numbers 4004 and 4005 These are my traverse 1 and traverse 2. This will be how I establish my traverse loop which because of the small size will probably have quite a small amount of error.

I am considering using existing control at Herbert Run to create control at the Knoll. Since I have specific coordinates for the traverse at Herbert Run I can use those to Run control down to The Knoll. This just means that I will have two traverse loops obviously the one that connects HR to the Knoll is far larger than the one that will be specifically for HR, which entails more error but we can distribute that error evenly throughout the loop and it will be fine.

Finally I am going to need to create the Grid points in GIS this week for The Knoll so that Monday I can get started on that.

Dana also had a great idea when we were out in the field she proposed that we use the GPS to guide us to the points that we are trying to survey. Sometimes these points are in the worst locations such as the points around 170 in Herbert Run and it can be a major hassle trying to read the map and decide what direction and how far is needed to pace to the next point. With the GPS we could get a much better rough estimate of where the next point to be staked out is, for those points that when using the map and actually walking through the forest are impossible to just pace to. This is the situation for large fallen trees in the way, large increases in elevation and streams.

Rendezvous with Brian Wagaman

I was able to get in touch with Brian Wagaman on Friday April, 13th 2012. What we had landed on was that I will meet him at Keystone precision on April 19th, 2012. I sent Brian Wagaman an email of Dr. Ellis email regarding billing for the data collector rental. When we get together on Friday Brian has agreed to instruct me on how to establish a network of control points via the traverse method with the data collectors that Keystone has available. This instruction will be completely free, the only charges will be for those of the data collector. I was going to ask if it is ok to take the instrument home Friday at the meeting Wednesday, Brian and I will use it for a couple hours then on Saturday I will work a twelve hour day Surveying the Bananas out of Herbert Run. I will need two volunteers for two shifts because I do not think anyone person should have to help me for more than six hours. the week following that I will have a gap between exams that will allow me to do the Knoll so it would be best to rent the data collector from Friday April,19th 2012 up till Monday April 30th that way I will definitely have ample time to finish the survey. 

I believe that this will dramatically increase productivity because I will not have to wait on control points. It will speed up the process ten fold. The survey of both the Knoll and Herbert Run should be complete by 4/30/2012.

I could have met up with Brian on Monday but I was swamped with two exams this week therefore I thought it would be best to rent the data collector for a short amount of time instead of just having it while paying for it and not actually using it for any surveying work.

Surveying The west side of HR

On Saturday March,31,2012 Dana and Shelby joined me in the field for a day of Land Surveying. Will Wiley was not able to come out this weekend and give us the points that we need to finish the survey but In the mean time Jonathan and I had decided it best to use this bottle neck as an opportunity to get the west side of the site done. We started with the points that were near the dam and moved East Until we ended up adjacent to the east side of the grid. We were able to get 18 points done that day between the three of us which leaves only 22 points left for this part of the grid. I will email Will Wiley again after this Wednesdays Ecosynth meeting to get an update about when a good time for him to go out to the field would be.The weather that day was really nice it was a bit over cast ( I managed to get a tan though!) and it stayed relatively calm with respect to the wind. This calmness made some of the points easier to get.Point number 102, in the thick of the brush, would have been nearly impossible on a really windy day. I really appreciated having two people out in the field to help me it seemed like things were able to go alot smoother just because we had extra hands to carry things. The point that seems to be in the middle of the dam 111 I did not put in because it seems like the contractors will come and clean that dam out periodically and it seemed futile to actually put this point down because of the constant grade changes that are likely to happen here. Hopefull we can finish the rest of the grid this weekend and have WIlls help this weekend also to get some new control points.

Surveying Friday 02/10/2012 with Kelly and Eric.

Today Eric and Kelly were able to accompany me in the field work. While we were out we were able to get 3 points layed out, determine a need for extra control and trouble shoot with instrument operations.

Surveying the first two points went just fine, but after the first two were staked out, I ran into a technical error that is best explained as the instrument was telling me to put the points in the wrong place 61 degrees away from where the points were supposed to go. It seems that whenever I want to re-establish my base line of 0 degrees, this particular instrument does not want me to do that. The only way to re-establish my baseline, or the line that I base all the other measurements with, is by completely re-entering the baseline station data. From now on this is what I will do to keep from wasting any more time.

Never the less we were able to stake-out three more points on the far east side of the Herbert run site. We had to do an offset for point number 152 because it was in the stream. What we did to obtain this point were two offsets one 7.12 m off of the point on the east side of the stream and another 2.68m off of the point on the west side of the stream. These two points are in line with each other and  if you pull an meter tape from one point toward the other the given distance for the offset you will be right on top of the point.

The first point 146 on the tree sampling grid, which was staked out the Friday 02/03/2012 prior to this one ended up 7 cm off. I am going to go ahead and wait till the grid is complete to restake this point out because it might be able to use a measuring tape instead of the total station.
