[postgis-users] questions about shape file

[Ludovico Bianchini]

Hi,
these are not strictly linked with postgis, but regard shape file, maybe here I can find help.

1) Is there a tool to build an union of shape files? Not an index file, but a new shape file containing all the features of the shapes used as sources.
2) Is there a tool to extract features from a shape file using an attribute of .dbf table as filter? and saving these extracted features in a new shape file?
