Math, math, math, and more math. Much of my week has
consisted of me doing math. As one can see in the new page, Photo Gallery – Drawing, I have been
transferring the digital satellite images to hand drawn versions with
dimensions. Each time I make a measurement, I reference all surrounding objects
to make sure that the measurement makes sense. Then after I am confident in the
dimensions, I input them into a Microsoft Excel spreadsheet which I’ve
formulated to do the quick conversions for me.
One problem I have run into is that the satellite imagery
gives me a great view of length and width, but will not allow me to measure height.
I am not sure how I might get the height so any suggestions will be
appreciated. One thought that has been bouncing around my head is the sun. I am
able to find the date on which the images were taken, as well as adjust the
time of day. Theoretically, I could use that information to find the angle of
the sun and then measure the shadows of the buildings to obtain the height.
This could be highly inaccurate or accurate depending on the integrity of the
images.
While this is a problem, the rest of the project has been
able to proceed. On Tuesday, the great people at Home Depot supplied and cut
the wooden base I needed for the project as well as gave me hints on how to
work with the wood for the buildings. Using the drawings I made with the scaled
dimensions, I have now transferred the grid to the wood. I can assure you that
it is not as easy as it sounds. I messed up on one road and had to redo the
entire sector. But working with wood has its advantages, such as calloused
hands and splinters.
As this week has wrapped up, I received two free quarts
of paint from ACE Hardware and will still be working on transferring from
satellite to paper to wood.
Suggestions or questions: comment below.
Perhaps you could go to google earth and go to street level, they have adjusted size of buildings with a scale near the edge. I think that you could use that to find the heights of the buildings. Great Pictures by the way!
ReplyDeleteJohn,
ReplyDeleteLove the building-shadow-calculation idea! However, I agree that you might not get the best measurements. A few suggestions I have include researching some major buildings (ie the specs for Chase Field might be online), or take a field trip to the areas you're mapping to get a relative idea (if all finite measurements fail) of how tall they should be.
Hope these ideas helped!
