You might need detailed information
about the map data sets in order to determine their type, size, the
variables that they contain, or, in the case of traditional map data
sets, whether they are projected or unprojected. You can get this
information by doing the following:
-
using the CONTENTS or DATASETS
procedure
-
browsing the MAPS.METAMAPS data
set in the MAPS library
-
browsing the MAPSSAS.METAMAPS data
set in the MAPSSAS library.
-
browsing the library where your
map data sets supplied by SAS reside
See The METAMAPS Data Set. Once the libref MAPS has been assigned,
you can see a complete list of map data sets by viewing the MAPS.METAMAPS
data set.
Run the following statements
to list the map data sets in the SAS library that is assigned to the
libref MAPS:
proc data sets lib=maps;
run;
Alternatively, you can substitute the libref MAPSGFK
or MAPSSAS.
Run the following statements
to provide detailed information about a map data
set, including the number of observations, the variables in each data
set, and a description of each variable:
proc contents data=maps.canada3;
run;
To see the contents
and descriptions of all of the map data sets associated with one of
the three map libraries supplied by SAS, specify one of the following
statements in the CONTENTS procedure:
See the
Base SAS Procedures Guide for more
information about the CONTENTS and DATASETS procedures..
