Figure 3. On a page-size diagram of Boston Harbor as a whole, differences between the three medium-to-high resolution files are not great. Agreement is good in many of the outer and middle-harbor areas. However, comparisons between the shoreline files and recent orthophotographs show significant local differences particularly in the inner harbor - Mystic River confluence. In these areas the NMRDVS lacks sufficient detail to effectively delineate the shoreline at larger scale. Click on the insets for more.
