## DESCRIPTION

The **Data Catalog** is a *[wxGUI](wxGUI.md)* component for browsing,
modifying and managing GRASS maps.

Data Catalog allows you to:

- browse GRASS projects and mapsets in the current GIS directory
- browse GRASS 2D/3D raster and vector maps
- rename, copy, move and delete GRASS maps including reprojection
  between different projects
- drag and drop maps for copying and moving
- searching and filtering maps using regular expressions
- display map in current project
- show metadata of maps

Note that projects are called *locations* at some places and in old
documentation.

## NOTES

Some operations (copying, renaming, deleting) are by default enabled
only within the current mapset. To allow changing data outside of your
current mapset, you need to press *Unlock* button in Data Catalog
toolbar.

### WARNING

When renaming, copying or deleting maps outside of Data Catalog, you
need to reload the current mapset or entire database, because it is
currently not synchronized.
