Nautical Charts and Making Shape Files
There are several nautical charts available in the course data folders: P:\GEOG462\data\PugetSound\NOAA\Nautical_charts
Note that these are not GIS layers, only scanned images of charts. However
these chart have a lot of very useful coastal information on them. It is
possible, of course, to digitize those items of interest from the charts and
create a shapefile from them. For instance, you could create a layer that has
all of the lighthouses in
Modeling tidal motion with multiple flow surfaces
Surfaces and interpolation were discussed in lab assignments 4 and 5. The
relationships between surfaces, contours and z-points were examined as
transformations. Beyond transformations on static surfaces, situations with
rapidly changing flows or direction were seen in air quality, precipitation,
tides and currents. Derivation of multiple flow direction surfaces was
demonstrated using digitized NOAA tide charts and interpolation. A sequence of
tide flow direction surfaces was connected iteratively to simulate the motion
and dispersal of material. The resources used to execute the simulation are
available for student project teams engaged with dispersal and/or deposition of
contaminants in the waters of the Sound.
The way to create flow direction grids from the tide charts and use them in a
flow model is described here.

Environmental Sensitivity Index data
Noaa's Environmental Sensitivity Index (ESI) geodatabase is available as part of the course data set. The easiest way to explore this very rich set of habitat, fish, bird, marine mamal and socio-economic data for Puget Sound is to load the existing map into ArcMap: P:\GEOG462\data\PugetSound\NOAA\esi\1262_pugetGDB\Puget.mxd
To use this data, you will want to load the geodatabase into your own map. Use ArcCatalog to examine the geodatabase. You will see it contains a number of supplementary tables as well as the feature sets. Each table is designed to link to one or more feature set. The linking information is in the metadata (1262_pugetGDB_metadata.pdf), but we have also provided a "cheat sheet" (ESI Data join notes.doc) to make this task easier for you.
Using the Watershed Tool to Delineate a Watershed from a DEM using ArcMap and Spatial Analyst
A "how-to" document for creating a pour point and running the hydrological analysis for delineating a watershed from a DEM is available:
