Teradata GeoExport Process - Geospatial Utilities

The following steps and examples describe how to export with Teradata GeoExport.

1. Create a table of geospatial data in the database:


   DROP TABLE customers;
CREATE TABLE customers(pkey integer, cust_name VARCHAR(10),
cust_zipcode VARCHAR(6) , loc ST_Geometry);
INSERT INTO customers(0, 'Anugu Raju', '500020', new ST_Geometry('POINT(20.34 80.78)'));
INSERT INTO customers(1, 'Madhava', '500081', new ST_Geometry('POINT(20.56 89.44)'));
INSERT INTO customers(2, 'Karthik', '500083', new ST_Geometry('POINT(19.12 88.22)'));
INSERT INTO customers(3, 'Subbarao', '500012', new ST_Geometry('POINT(21.45 88.12)'));
SELECT * FROM customers ORDER BY 1;

2. Run TDGeoExport to create an ESRI Shapefile from the customers table.
   Include the terajdbc4.jar, tdgssconfig.jar and tdgeospatial.jar in the classpath.

   • 32-bit path:

     rm c:\temp\geodata\*
     cd c:\temp\TdGeoImportExport\bin
     java -Xms256m -Xmx1024m -classpath .;tdgssconfig.jar;terajdbc4.jar;"C:\Program Files(x86)\Teradata\Client\<version>\bin\tdgeospatial.jar";
     com.teradata.geo.TDGeoExport -l hyvm20/geouser, geouser -s geouser -t customers
     -f "ESRI Shapefile" point -o c:\temp\geodata -n customers

   • 64-bit path:

     rm c:\temp\geodata\*
     cd c:\temp\TdGeoImportExport\bin
     java -Xms256m -Xmx1024m -classpath .;tdgssconfig.jar;terajdbc4.jar;"C:\Program Files\Teradata\Client\<version>\bin\tdgeospatial.jar";
     com.teradata.geo.TDGeoExport -l hyvm20/geouser, geouser -s geouser -t customers
     -f "ESRI Shapefile" point -o c:\temp\geodata -n customers

3. Validate that the ESRI shape files were generated in the c:\temp\geodata directory. The output ESRI shape files will show up in c:\temp\geodata.
