Originally developed to facilitate allied military operations, the UTM provides a metric-based coordinate system that is simple to use, precludes negative coordinate values (a potential source of error during data transfer and analysis), and is commonly employed in environmental and other geographic analysis. Use of the NAD83 ensures both compatibility with modern surveying systems and the highest degree of accuracy currently possible for South Florida regional geographic analysis. < Conversion Factors | Spatial resolution, location and extent >
