Transferring...


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.

  1. 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!

  2. John,
    Love 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!
