You could also write a fairly simple python script using the gdal/ogr python modules.

The method is ugly. I used this method to select lat-long values from a shape file consisting of about 150 records. Using this method all lat-long values from a shapefile consisting of place names of country can be selected and saved into files. I already told method is dirty. You can find using postgreSQL. first you should install postgis-postgresql package. and follow instructions in postgis manual. you want to import some files after installing postgis such as lwpostgis.sql etc... I think you added necessary attributes in shape files such as name of place etc,.. create a database in postgresql with postgis enabled (say db1) Now import .shp files into postgresql using cmd: you should have a database db1 with postgis support. shp2pgsql /root/vect1.shp vect1 db1 > /root/vect1.sql now you got vect1.sql file import sql file into postgresql. psql -d db1 -f /root/vect1.sql Now logon to postgresql admin tool such as phppgadmin or you can do these thing from postgresql interactive terminal. In the database db1 now you have another table name vect1. vect1 has some other attributes such as gid,the_geom etc.. other than attributes you have entered. 'the_geom' is the geometry of shape file. select X(the_geom) from vect1; query executes to display longitude all entries in shape files and select Y(the_geom) from vect1; query executes to display latitude all entries in shape files this data can also be inserted into table by inserting a new column for latitude and longitude. If you want table back to shp files using the cmd: pgsql2shp -f vect1 -p 5432 db1 vect1 Or You can also export column latitude and longtiude into mysql also as you wish -- Regards, Mohammed Rashad K.M http://keralainfo.web4all.in/ +919605476742
