### Menu Bar

#### 1. File Menu

TerraView uses the concept of Project to save the state of a working session. The project file is saved in XML format and keeps information about number of layers added, layer style, layers classification (Legend). Another xml file keep information about the datasources used. This two files can be saved by demand and when the application is closed.
Click on File > Save Project, Save Project as or create a New Project. The project name informed here is the name of the xml file that keep information about the project.
Click on File > Open Project or File > Recent Projects to open an existing project (*.xml).
Click on File > Restart System to restart the application if some user configurations have being changed.
Click on File > Exit to close the TerraView Application

#### 2. Project Menu

Click on Project > Add Layer... to add layers to the project and choose the layer type:

- Vector File... to choose one file of Esri shapefile , MapInfo, GeoJSON, GML, or KML format (only available if the corresponding plugin is loaded).

- Raster File ... to choose one file of image format. To choose more than one press Ctrl+ Click filename (only available if the corresponding plugin is loaded).

- Tabular File... to select a tabular file such as CSV, txt, dbf format.

- From Data Sources... to select a datasource from where to pick up the data. See the Data Source Selector and Dataset Selector interface.

- Query Dataset... creates a layer defining a restriction clause on an existing layer.

Also it is possible to use Project > Add Folder Layer... and drag some layers into this folder to organize better the Layer Explorer. If a folder is removed, all layers inside are also removed.
Click on Project > Remove Layer(s) to remove the selected layers.
Click on Project > Rename Layer... to rename the selected layer.
Click on Project > Properties... to see Title, Author, Location and Description of a project.
Hints: To display something go to Layer Explorer and select some layer(s). To draw the selected layers go to the Map Display and choose Draw. To save the project go to File Menu.

#### 3. View Menu

Click on View Menu to set or unset items which will compose the Main Window.

- Data Table
- Layer Explorer
- Map Display
- Style Explorer

- Full Screen

- Tool bars

Usually the default settings are only Map Display, Layer Explorer and Tool bars to keep the drawing area as big as possible. The other options can be set and unset when necessary.

#### 4. Layer Menu

The tools in this menu reflect operations on a selected layer. The tools are:
Operations tools:

- Classification...

- Histogram...

- Pie/Bar Chart...

- Scatter...

- Query...

Visualization tools:

- Fit Layer: Will expand the selected layer over the map display area.

- Fit Selected Objects: Will fit all selected objects over the map display area.

- Pan to Selected Objects: Will pan over the selected objects.

Shows/Hide components associated with selected layer.

- Show table

- Style Explorer

Selection tool:

- Remove Selection: Will remove any selection at the map display and show all the objects displayed with the original Style (color, mark, etc).

Spatial Reference System Tool:

- Inform SRS...

Property tool:

- Properties: Will show layer properties, including the SRID.

#### 5. Map Display Menu

The tools in this menu reflect operations over the datasets presented on the map display or selected in the layer explorer. These tools are grouped according with the functionality as described bellow:
Drawing tools:

- Draw: All layers with box-checked in the Layer Explorer will be draw at the Map Display.

- Stop Drawing: Stops the drawing of layers.

Selection and information tools:

- Info: Show information about the objects pointed over the layers selected and box-checked.

- Remove Selection: Remove selection and show the objects with the original color and style.

- Selection: Allows to highlight objects pointed by the cursor, or objects that intercepts the cursor-area.

NOTE: The selection tool is valid over the selected and box-checked layers. If the associated Table, or some graphics like Histogram are visible, the same objects will be also highlighted (brushing).
Visualization and navigation tools on the layer:

- Zoom Extent

- Zoom In

- Zoom Out

- Next Extent

- Set Unknown SRS: Allows to set the map display SRID to unknown. It is used to draw layers without SRID (0).

Right-Clicking over any point over the map display shows the same Map menu as a context menu.
NOTE: Some tools/actions affect only the selected and box-checked layers, others affect all box-checked layers and others affect only the map display.

#### 7. Plugins Menu

From here a component called Manage Plugins... allows you to add, remove, load or unload plugins. See the session How to Load/Unload Plugins for more details. Also see how to use them at Using available Plugins session.
