You have spent your summer holidays in this beautiful island with green-forested hills and babbling brooks. Photographs that you have taken are unable to capture the enchanting panoramic view of the island.
You want to recreate the landscape and impress your friends. Well, here is a hands-on solution.
The things you need,
A pair of setsquares
A few sheets of paper
Run safety checks before you begin.
One, that you have all the benchmarks of the area,
Two, that all the lines you select runs through them benchmarks, and
Three, that you carefully select lines which are parallel to each other.
Now, what are benchmarks? These are virtually permanent points of reference laid down on the land by a persevering and inspired surveyor for future reference.
The height above the sea level is plotted at a specific point and painted or chiselled on to rocks or erected as posts.
How to get about it?
First you have to select a straight line cutting across the landscape. Let us name this line AB. The benchmarks on this line can be plotted on to paper.
The x-axis depicts the height, while the y-axis depicts the location of the benchmarks, i.e. distance. Now do you have a profile like the one shown below?
Take two more lines parallel to the one you have taken and name it CD and EF. Construct their profiles like the one above. Well, you have now captured the salient and individual features of the area.
You know exactly where each mountaintop and valley is located. Well, these are the infamous serial… no not killers… but profiles.
How does one make block diagrams?
Now if you place all the profiles on top of each other, fitted to same frame of x and y axis, what do you think will happen? Viola superimposition!
However, if you lower the base of each frame, taking care to place the profile of the first line lowest, you will arrive at a block diagrammatic representation. With a little bit of expert shading shading the landforms will emerge in front of you. Well, what else can you do with these serial profiles?
One, as we promised, you can create a panoramic view of the landscape, and second you can draw beautiful sunsets and moon-lit starry skies with the rugged skyline.
How to create a panoramic view?
This is perhaps a little complicated, although not difficult at all. Well, you have all the serial profiles. Now, place line AB and CD on the same frame. Let line AB remain as it is.
When placing line CD only trace out the part that emerges above line AB. Likewise when placing line EF trace out only that part which lies above line CD. This way you will emerge with a 3D effect that you thought was only possible in the computers. This is known as a projected profile.
How to create scenic skylines?
This is the simplest of all. Imagine you have woken up in the middle of the night and wandered outdoors in your scenic island. What would you see?
Inky blue outline of distant mountains with starry skies atop. All you have to do to get this effect is draw the topmost outline of each serial profile. Simply put, start from the highest profile, and mark only the portion that lies above this from the following profiles, creating what they dryly designate as composite profile.
Well, after you have succeeded, which you surely will, pat your back and consider it a job well done!
