Versioned GIS Editing Demo (GeoServer, OpenLayers)

openstreetmap

the openstreetmap conference is hosting in Amsterdam , it is nice to be there. OSM member got free access. otherwise, you have to pay Gelds…..

as we know, if there is a plane crashed, the only evidence or data of the plane is the black box. and what is a black box. Normally, it is very very very strong metal tape recorder, which can record all kinds data of airplane for certain length(such as, store 30min data before it crash). however, the problem is that , if the black box cannot find back, you dont have any data left. it doesn’t matter how many black box you store in a airplane, it doesn’t matter which safe position you stored. actually, it is never safe to store it on airplane. because it will crash.

I am GIS people, we are think in spatial way. why not design a GIS system for airplane? the airplane send instantly data back to central server via satellite. nowadays technology, i think our IT engineering can make it come true. as i know, people recording all satellite data, which orbit it running, which height, which position. they all can be remotely stored in somewhere else, you dont need to store the data on satellite.

in future, there should be some system can store all data of flying object on the ground. maybe  google will solve the problem, google have a big index database. it index everything on internet. from ge, sometimes we can some dynamic maps of satellite or ships. So GIS technology is a good solution for engineer get rid of the black box. why we need a old tape recorder in 21st centuries.
