The Global Forest Disturbance Alert System (GloF-DAS) provides data on forest disturbance globally on a quarterly basis.
Reliable maps of global forest cover change are frequently years out-of-date. Consequently, there is a pressing need to develop techniques for monitoring and verifying land cover change and forest disturbances in a timely, low-cost, and accurate manner. Satellite remote sensing from instruments such as NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) offers a consistent and cost-effective method for mapping forest cover change. MODIS data are obtained freely with global daily cover products. Deforestation tracker You can select time period and location on the map. |

I've just been browsing this and cross-referencing it with the Northern Australia Fire Information (NAFI) site, because Dec 2011 shows changes to the cover around Mt Bartle Frere (Wooroonooran* NP). There hasn't been fire or timber getting in that area**, but I wonder if that recorded change is associated with the dry season? (Although they do say they take seasonal changes into account. Hmmm.)
_____________ * Yes, it took a few goes. ** That I know about. I will have to ask. |
