Geography Reference
In-Depth Information
17. Expand the FGDC Metadata > Identification and record the following information (if you can):
West Bounding Coordinate (geographic): _____________________
East Bounding Coordinate (geographic): ______________________
North Bounding Coordinate (geographic): _____________________
South Bounding Coordinate (geographic): _____________________
So there seems to be a little problem here. We don't really know the coordinate system. No
geographic coordinates are shown. The bounding coordinates are presented in “projected or
local coordinates” but not in decimal degrees. Does this data set relate to the Wildcat Boat
problem?
Is the Newly Found Data Applicable?
Although the Landcover coverage and the Soils personal geodatabase feature class probably occupy
the same piece of real estate (note that the projected coordinates you wrote down previously are
approximately the same for both), you have to make sure. Suppose that, by looking at some paper
documentation, you are able to determine that the projected coordinates shown are in fact in meters
and the projection of the coverage is WGS84 UTM Zone 18, just like your other data. So you should fix
up the coverage so that it has the same spatial metadata as the other data sets. You can do this with
ArcCatalog. When you were reviewing the Landcover coverage (in Other_Data), you may have noticed a
SOILS coverage also. Maybe, since they're in the same folder, they are related and SOILS has the needed
metadata.
18. In the ___IGIS-Arc_ YourInitials \Other_Data folder, check the spatial metadata for the SOILS
coverage against the spatial metadata for the Soils personal geodatabase feature class,
located in
___IGIS-Arc_ YourInitials \Wildcat_Boat_Data
\Wildcat_Boat_Data.mdb\Area_Features
Also check the coordinates for the SOILS coverage against the coordinates for both the Soils personal
geodatabase feature class and Landcover coverage.
Do they have the same coordinate systems (including the false easting and false northing)?
____________________________
Are the projected coordinates similar? _______________________
So at this point you should feel comfortable simply assigning the Soils datum and projection to the land
cover data.
