Transform graphic noise map to coordinates
Closed - This job posting has been filled and work has been completed.
We have two sets of geographical data that need to be linked together. One is a high-res image of noise pollution in the city of Prague, the other is a list of all address places in the city (cca 120k) along with their gps coordinates. The goal is to get the noise data to the addresses
Here is the map - http://hlukovemapy.mzcr.cz/image.a
We are interested in the 6 noise segments and a presence of train tracks within close range. The way how to do it is open to discusion, one option would be to attach the highest noise segment present within aprox. 50m radius to each address point.
The expected skill is mainly gis software. The job should take few hours to complete.
