:information_source: 3dcitydb-qgis-explorer is in **archive mode** with no significant active development planned. We recommend using the [**3DCityDB Tools for QGIS**](https://github.com/tudelft3d/3DCityDB-Tools-for-QGIS) instead.

# Description

This plugin allows to load stored in a [3D CityDB](https://www.3dcitydb.org/3dcitydb/) in [QGIS](http://www.qgis.org). Is it possible to load the data in a 2D and 3D view.

**Important notice**: this plugin is currently in the development phase. Only **PostgreSQL** is supported and currently only **LOD2** data can be loaded. Pull Requests are welcome!

## Install from ZIP

The plugin can be installed using the _Install from ZIP_ Function in the Plugins Window (_Plugins_>_Installs und manage plugins_).

## 3DCityDB Explorer Widget

- _Databases_: This is a list of the current PostgreSQL connection saved in QGIS.
- _Connect_: Create a connection with the selected Database.
- _Max Features_: The max number of features that will be loaded in QGIS. This is useful if requesting data for a big extent. This limit remains valid also when using zoom or pan function.
- _Add buildings_: Add the Buildings for the current extent.
- _Edit Attributes_: Start the edit modus. The mouse cursor wll change in a cross icon and with a click on building is is possible to edit its attributes. Clicking once again on this button will stop the edit modus.

## How use this plugin

1. Add a new PostgreSQL Database connection. This can be done, for example, in the _Data Source Manager_ under the _PostgreSQL_ block. Use the parameters of your 3DCityDB (hostname, port, user, etc..).
2. Start the plugin Widget from the Database Menu (3DCityDB Explorer > Open Widget)
3. Choose your 3DCityDB from the dropdown menu and click connect. If the connection is successful, you should see the version of the 3DCityDB.
4. With the button _Add buildings_ the LOD2 (the current version of the plugin supports only LOD2) buildings can be loaded in QGIS. The max number of loaded features is controlled by the parameter _Max Features_.
5. With the button _Edit Attributes_ ist it possible to edit the attributes of a specific geometry. Simply click on this button to activate the edit function and click on a geometry. A new Window will open with the current values of the selected geometry. Change the values and click _save_ to store the new values. To exit from the edit function, simply click once again on the _Edit Attributes_ button.
