Data mining examples -- Images of fires in Indonesia and U.S.A.
| Haze from fires is thick over the Indonesian island of Borneo. Scores of wildfires (red dots) were detected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite on August 19, 2002. The region has recurring trouble with smoke and pollutants from wildfires, which are often the result of slash-and-burn agriculture. In addition to being a health hazard, the smoke can disrupt air traffic, as it did recently in Malaysia, on the northwest portion of Borneo. | |
 Publication Size | The Indonesian island of Borneo (top) is barely visible beneath a blanket of smoke from numerous fires burning there. The smoke is so thick in fact, that the Moderate Resolution Imaging Spectroradiometer (MODIS) that captured this image had trouble pinpointing the active fires (red dots). Inspection of previous images shows the abundance of fires. At the bottom of the image is Java. |
 Larger Size | Major ecosystem disturbances detected in North America. NASA image of patterns in the 18-year record (1982-1999) of global satellite observations of vegetation greenness from the Advanced Very High Resolution Radiometer (AVHRR). Different colored areas identify the major ecosystem disturbance events detected and the year they occurred. The majority of potential disturbance events pictured occurred in boreal forest ecosystems of Canada or shrublands and rangelands of the southern United States. |
