Putting it All Together
GIS
technology has made the task of map overlays so easy that it's easy
to get carried away and make overly complicated GIS maps that owe
more to modern art than to cartography! So, the phrase "Putting
it All Together" has to be taken with a grain of salt; in some
cases, it might be more of a goal than a physical reality. In this
case, because tidal wetlands, migratory fish runs and SAV areas are
often contiguous but rarely overlap, and because it's extremely rare
(unfortunately) to have extensive areas of all three in the same
stretch of coast, we can afford to put all on the same map. The choices
come with the land-based information, which cannot all be overlaid
on the same map. In this case, we decided to include two examples:
the top map shows the coastal resources with some of the water features
and the watershed-based impervious cover map; the bottom map shows
the coastal and water resources contrasted with the urban growth
map. As we've described on those tutorial pages, both will be useful
to people trying to assess current and future threats to coastal
resources. We invite you to do your own analyses, using the interactive
and downloadable mapping resources on the Mapping
Station site.
