Talk:Google earth mapping
Google earth can also be used to map the locations of resources which can be gathered. An example is steel from shipwrecks.
A kmz can be made from the graveyards; see http://www.gearthhacks.com/forums/showthread.php?t=6433
Mapping cooperation with shipwrecks
the costs of the preposition to map out the stranded ships can be reduced by an approach which would allow the map-out to be done much more economically. This approach would be the use of satellite imagery from Google Earth/Google Maps (which is easily and freely available online) to allow volunteers at home to spot the shipwrecked ships themselves and report/mark them (marking too may be done with Google Earth). When the images are not clear enough to definitly say whether or not certain items on the map are indeed stranded ships, they may pass along the information to people on the ground (government-sponsored organisations, ...) to go check out the spot/GPS-location in question.
Extra information Similar project conducted with the search to Steve Fosset's plane http://www.wired.com/software/webservices/news/2007/09/distributed_search
When the wrecks are determined, the info could then be used by directing salvaging (or scrap collection) teams to the locations. These can then collect metals using w:Oxy-fuel welding and cutting
Coral reef degredation
The decline of coral reefs should be mapped out in Google earth. A KMZ could perhaps be made which marks zones covering the areas of a specific degree of degredation. Colors can range from yellow over orange to red.
This KMZ could help in the determining of coral reef restauration project sites. See http://en.wikipedia.org/wiki/Coral_reef#Protection_and_restoration for some coral reef restauration info. I'm guessing that funding should be possible from coral reef or environmental organisations as little action has been taken in the past.
Some coral reef restauration projects (Reef Ball & Artificial reef.com projects) are already available by KMZ. See http://www.artificialreef.com/, see http://www.reefball.org/index.html (DraftGiude pdf page 23 and 29)
Vegetation decrease and original vegetation
The vegetation decrease be shown in another KMZ. http://www.intactforests.org/introduction/images/map_general.png http://maps.howstuffworks.com/world-forest-cover-map.htm can be used to make the layer. The image should be the IntactForests image layered over a pencil line marking the extremeties of the howstuffworks vegetation cover map. Note that it is perhaps best to move the intactforest coloring to the howstuffworks map, add the pencil line and delete the howstuffworks coloring
The area between the pencil line and the still currently present vegation, should be colored red; Vegetation (current) should be green.
The KMZ could be used to help planning to revert the earth to its original degree of vegetation (either in original form or a form where the same amount of vegetation is present, yet on other locations; eg using areas which once unproductive as certain deserts).
