False Color Imagery

Here is an example of false color imagery, can you see how the Indian pictograph stands out a little more when viewed with a false color filter? Different colors are simply being defined differently, but it is a tool remote sensing specialist use to help identify patterns or features that we may not otherwise have noticed. 

Pictograph was created about 1000 AD by Fremont Indians in N Utah

Lidar Massachusetts

I have created several more Lidar maps but this time they are all based in Massachusetts. The Lidar data itself was not as high resolution as the Utah data since they are a few years older but they are fun to look at. What a difference a few years make as newer sensors and methods are used. My favorites are probably the Boston Harbor Islands and Provincetown maps. Enjoy!

Lidar Salt Lake City

Introducing downtown Salt Lake City through the eyes of Lidar. This map

was made from public Lidar data from the AGRC. It is based off of a DSM 

(Digital Surface Model) that has been processed with a hillshade. It reminds 

me of a classic plat map or some of those city word art maps. Salt Lake's

unique geography really helps bring out this feeling. This will hopefully be

the first of many as I delve into other cities datasets and try to make similar ones. 

Please let me know if there are any cities in particular that you would like me to look 

at first. Also, if you are interested in a nice print version just send me a message or 

leave a comment below.
