With the select duplicates tool you can quickly locate duplicate geometries through the attribute table.

The system requirements are the same as those required for gvSIG 1.10.

This extension should be installed on the version of gvSIG for which it has been developed. This is indicated in the Downloads table for the extension. This version must be properly installed on your PC using the following steps:

WINDOWS:

Download the EXE file from the Download Site on the web and then run the file. If the installer does not automatically find the directory where the correct version of the application was installed then this must be entered manually. For example, for gvSIG 1.10 on Windows XP the installation directory might be C:/Program Files/gvSIG_1.10

LINUX:

Download the BIN file from the Download Site on the web and then run the file. If the installer does not automatically find the directory where the correct version of the application was installed then this must be entered manually. For example, for gvSIG 1.10 on Ubuntu 9.10, the directory might be /home/user/gvSIG_1.10

The Locate Duplicates tool can be used to quickly locate duplicate geometries in a layer's attribute table.

We try to incorporate new functionality demanded by the Department of Health and Environment of the City of Munich.

This particular feature, aims to select the rows containing a particular repeat value, this value to be considered for comparison is obtained from the pre-selection column.

This extension of gvSIG is an independent and uses the core to perform its functionality without changing the core code, but they develop and improve it.

To establish an overview of situations where this component from the rest of gvSIG, we need to select the duplicate records depending on the previously selected column.

This plugin will add a unique extension of gvSIG with this functionality, therefore, provides the plugin code stays in the background image within gvSIG, without going into FMAP.

It is a new feature that it aims to select the features repeated in the table as the value that a particular column and previously selected.

• Extensions provided by this plugin:
