NC Map Project, Part 3

Remember to save things to the flash drive earlier before the end of class comes. I'm still struggling with the issue of managing all these large files. I was working away and then it was 10 minutes before the end of class. So I went to save my files from the hard drive to my flash drive. and it says it's going to take 35 minutes, then 17 minutes, then 194 minutes. Pete wants to leave on time, and Haven is there, and she wants to leave too, because of the mouse situation at their house. She's all consumed with the mice as far as I can tell. As the minutes tick down, it's clear that I'm not going to get my files copied to the flash drive any time soon. Pete intervenes and puts my files on his portable hard drive. Why is the actual hard drive faster than the flash drive with no moving parts? Seems like the archaic whirling metal disk hard drive would be slower than completely motionless memory. I guess flash memory is just not that fast.

Below is the image I was working with tonight. The elevation data is in raster format. It's really quite beautiful. Raster data is something I'm pretty familiar with from working with digital photos. Where each pixel in a photo has qualities, like it's color and brightness, each cell in the elevation data has a quality. That quality is it's elevation. In the case of the image below, the elevation data for each cell is just converted to a shade of gray, with the highest being white. You can display it in many different colors, and process the data to simulate 3 dimensional views and stuff.
