Can a GIS technician with some remote sensing experience pick up these data sets and use them?
The data can be viewed easily, using GIS or remote sensing software; however, interpretation may require additional training in remote sensing fundamentals. Do these data require a trained technical person to analyze the data? That depends on the extent to which the data are to be analyzed. Most GIS technicians can delineate basic features from the imagery without any remote sensing or photogrammetry knowledge. Detailed classifications and analyses, such as vegetation identification, will likely require additional training or the hiring of remote sensing-trained personnel. Are there some nuances with the data that could really slow you down? Occasionally the data can have quality problems. The most typical manifestations are data noise and data drops. Sources of high radiation such as fires and volcanoes can saturate a sensor or cause temporary interference after the sensors receive the high radiation. What are the limitations of TM and ETM+ data? These data cannot be used in lieu of h
