Purpose:
to create a geodatabase schema for the final project of Geographic Information
Systems II to be used for individual, state, research or educational purposes
involving the Matanuska River in South Central Alaska.
Methods:
To create a geodatabase schema, ArcCatalog was the program used. The first step
was to create several geodatabases using file geodatabase. Those included
Cities, River, Roads, and State. In the Cities geodatabase, two feature classes
were added, which included mv_cities_pt and Sutton. In the River geodatabase
two feature classes were added which included Matanuska_Single_Line_Hydro and
mv_major_river_In. For the Roads geodatabase two feature classes were added
which include Glenn_Highway and mv_infra_road_IN. The State geodatabase
includes three geodatabase feature classes which include Alaska, counties, and
the MatanuskaBoroughboundary. The
feature classes were included because they all share a common coordinate system
of nad1983_13N, and are related to the geodatabase. For example, mv_cities_pt
and Sutton are similar to the Cities geodatabase.
Topology was not included because it was not needed to
be used. Annotations will be included at a later date because some of the
labels are not accurate. Metadata will be used for feature classes of Glenn
Highway, States, and Sutton. The Roads were coded domains with values at local,
highway, major.
The files for the geodatabase were obtained from http://www.asgdc.state.ak.us/
The photos that will be used for this project were
incorporated into a raster database because they were already in a raster set.
Those photos are 1949 ortho photograph,1960, 2006, and 2016.
Results:
The figures below are the
results of the geodatabase schema.

Conclusion
The geodatabase created for the final project should be used
for personal, educational, research, and other related purposes. Creating a
geodatabase helps to organize files so that others may use it.
