Check out the Hawaii Relief Map by pmoews, Thingiverse Thing 105474. He has been creating a number of these in the last few months, including the Gulf of Mexico in Relief and Earth Sea Relief Globe.
Here is a relief map of Hawaii, the Big Island.
It is based on a NOAA digital elevation model or DEM – hawaii_6s_20070806.asc.
The data set consists of an array of real numbers with 3000 rows and 4200 columns. The distance between points is 6 arc seconds. A 200 by 200 array, sampled at 30 arc second intervals and surrounding Hawaii, was used to make the stl file. Points below sea level were set to the sea level value.
In the model the highest peak rises about 20 mm above sea level. The highest peak on Hawaii, Mauna Kea, is 4200 meters above sea level.
NOAA has a portal that helps one find many similar data sets. See http://www.ngdc.noaa.gov/mgg/dem/demportal.html
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
