The map is fully functional and can be zoomed, panned, and changed into a road map with the controls on corner of the map window. Click on the markers to see information about each instance. Some markers overlap; zoom in to separate them. The Street View pegman can be dragged to roads that include this feature, which can give you panoramic roadside views in some countries.
What the numbers mean: Soil carbon, which makes up half or more of soil organic matter by dry weight, is usually measured as organic matter percentage of a soil sample, or in tons of carbon if the density of the soil and the volume of the sampled layer are also measured. To get a carbon dioxide equivalent, multiply tons of carbon by 3.67.
This is a spot map. In nearly every case, the changes recorded are heavily influenced by the decisions made by those managing the land. If you have data that you can contribute, please contact us.
