proc import map

Hello Experts,

I am trying to create a weight matrix for my economic model. I have a  shapefile of the census tracts for the state of missouri. When I open the shapefile or dbf file on any other application, it contains 1393 observations which is the total number of census tracts in the state but when I import into SAS, I have 974962 observations with multiple xy coordinates of the same geoid. Any idea why and how to resolve this. Thank you.

/*Import shapefile*/
proc mapimport out=me.mo_shp datafile="C:\tracts\mo_new.shp";
id geoid;
run;

Proc Mapimport imports a shapefile into SAS, such that it can be used as a map and plotted with Proc GMap or Proc SGMap. All of the X/Y's are the coordinates along the border of areas in the map (in this case, Census Tracts).
