shp转换

Example usage of the shape to sdo converter for Oracle9i Spatial and higher versions -

on Windows NT:

shp2sdo.exe states states -g geom -d -x (-180,180) -y (-90,90) -s 8307 -t 0.5 -v

on Sun Sparc Solaris or Linux:

shp2sdo.exe states states -g geom -d -x \(-180,180\) -y \(-90,90\) -s 8307 -t 0.5 -v

In the previous command:

states - the shapefile to convert (expects .dbf, .shp, and .shx files)

states - the name of the table to create and use in Oracle

-g  geom - geom is the name of the column to load for the geometry object

-d     - put the data in the control file generated by the tool

-x     - the bounds of the first dimension in the coordinate system

-y     - the bounds of the second dimension in the coordinate system

-s     - the SRID (spatial reference system ID)

-t     - the tolerance

-v     - verbose output


If the target database is Oracle8i, then use the -8 option on the 
command line.

                          if not specified, 6 digits of precision is used
  Options valid for the relational model only:
    -c ordcount         - Number of ordinates in _SDOGOEM table
                          if not specified: 16 ordinates
    -n start_gid        - Start number for GIDs
                          if not specified, start at 1
    -a                  - attributes go in _SDOGEOM table
                          if not specified, attributes are in separate table


After running the shp2sdo converter the next step is to create the Oracle table
and load the user_sdo_geom_metadata table.  The file used to do this is generated
by the converter.  In the example above, it would be called states.sql.  Log into
SQL*Plus as the user who will own the layer, and type: 

@states.sql.

After this, load the data using sql*loader.  In the above example, assuming
user scott with password tiger, do:

sqlldr scott/tiger states

After the layer is loaded, the final requirement (for polygon layers only)
is to migrate the layer to the 8.1.6 and higher format (fixes the SDO_GTYPES 
and etypes as well as all polygon rotation and ordering requirements).  
After logging into SQL*Plus:

If you are using Oracle8i, type:

EXECUTE SDO_MIGRATE.FROM_815_TO_81X('STATES');

If you are using Oracle9i or higher, type:

EXECUTE SDO_MIGRATE.TO_CURRENT('STATES','GEOM');
