Welcome back. And for this lecture, we're outside. In this lesson, we're going to be doing some mapping out of the property. And also, we'll be doing three different kinds of measurements. They're called the running measurements, the direct measurements and the triangulation. Before I start up doing the survey, I'll explain what these three terms refer to.

So it's our measurement, it's pretty much exactly what it says, I'm measuring. So for example, I have this patio here that I want to measure. So I'm just gonna put the measuring tape down. And it's hundred and 40 centimeters. So there's the direct measurements. It could be a semi forehead, blank wall without any window or door.

So I'm just measuring from here to there, and there is no other element to the cap. So that's it. So now I'm going to demonstrate running measurements. So we have this wall where we have a door. So we're going to start from the opening of the door, a bunch over the hinges, so it's 110. And then from here, up until the end of the window, which is 230.

And then from here to the end of the walls, so it's three meters. So the running measurement, it's an accumulative measurement system, where instead of measuring the individual distances, you measure distances all the way across and you add in the cumulative distances all the way across. If I was to turn a corner, it would be a brand new measurement, I would not continue to run in I would start at zero and that's The idea of running measurements. Okay, so let's talk about triangulation, triangulation simply using two known points to locate a point that you're not sure of as how it fits into the landscape. So in this case, we've measured this building so we know the dimensions. And I have this beautiful rose here.

And it could be a tree or water feature or a pot, I want to know very exactly this object is in relation to this building. So to locate it correctly, I'm going to be using the method called triangulation. And to do that, I'm simply going to measure from one side of the building over to the center of the object. But I don't know what kind of angle the rose actually is. So now we're going to do the same from the other corner of the building towards the center of the object. So now we know the measurements, we can take the value into our drafting, compass and drawing that From one side and from another and ready to meet, that's the center of the object.

And from there, we can also draw a diameter of the object accordingly. So whether it's a port, a tree, a water feature, you can do the triangulation now very easily, I would suggest to maybe go out, map your own property and practice so you get the experience. And if you do have any questions, let me know and I'll get back to you as soon as I can. Okay, let's go to the next lesson.
