User Interface¶

The Gisquick clients are designed with a goal to put together minimal set of functions for useful generic responsive web and mobile friendly mapping application.

The major part of the clients User Interface (UI) is occupied by map canvas (1). On the left side is located content management tools (2) which is possible to hide by button on its right side (3). Corners of map canvas are filled by (from left-bottom corner, clockwise) by map scale (4), tools (5), user menu (6) and zoom tools (7). In the bottom part is located statusbar showing current scale, projection and map coordinates of the cursor (8).

Figure 1: Gisquick user interface description.

Content management tools¶

Basic project metadata - project description - is accessible by question-mark, see figure below.

Figure 2: Project description.

Content management widget is split into three major tabs:

Base Layers
Overlay Layers
Legend

Figure 3: Content tabs.

Base Layers tab allows switching base layers in map canvas. The list of base layers is defined by publication process as described in Project publishing section.

Figure 4: Switching between base layers.

Overlay Layers tab allows switching between topics (layer groups), see Project publishing section, or controlling overlay layers one by one.

Figure 5: Topics and layers switcher.

Figure 6: Switching between topics.

In Layers mode the overlay layers can be switch on/off one by one.

Figure 7: Switch on/off overlay layers.

Tip

It is also possible to switch on/off group of layers .

Explain legend.

Attribute data¶

In Layers mode attribute data can be accessed by . Attribute table is displayed in bottom part, see figure below.

Figure 8: Layer attribute table.

Attribute table allows filtering data based on simple queries, see figures below.

Figure 9: Choose operator for attribute filter.

Figure 10: Define filter and refresh attribute table view.

Tip

By default, attribute table shows only few rows. The number of displayed rows can be controlled in status bar by Rows by page. Attributes can be also filter by map canvas Filter to visible area.

Every row in attribute table has Zoom to button which enables zooming and centering related features in map canvas, see figure below.

Figure 11: Zoom into selected feature.

Note

Attribute filter can be disabled by . Table view must be refreshed.

Explain info panel.

Zoom tools¶

Zoom tools enables controlling map view.

Geolocation
Zoom in/out
Zoom to extent

Figure 12: Geolocation in action.

Tip

Zooming and panning is also possible by middle mouse button.

Tools¶

Two basic tools are available:

Identify , and
Measurement

Identify¶

By default, features are identified in all visible layers (in the example below in Schools and District layers).

Figure 13: Identify schools and district layer.

This settings can be changed in Identification combo box.

Figure 14: Change layer priority for identification.

Measurement¶

Three measurement modes are available:

Location (point coordinates)
Distance
Area

Figure 15: Measurement tools.

Figure 16: Location measurement example. Menu highlighted in red box.

Location menu allows:

Zoom to location
Change spatial reference system. By default two system are supported: QGIS project system and WGS-84 (EPSG:4326) known as “GPS coordinates”.

Figure 17: Location menu.

Figure 18: Distance measurement example. Menu highlighted in red box.

Distance menu allows:

Zoom to distance
Change units. Currently two systems are supported: international (EU) and imperial (UK, US)

Figure 19: Distance menu.

Figure 20: Area measurement example. Menu highlighted in red box.

Area menu allows:

Zoom to distance
Change units. Currently two systems are supported: international (EU) and imperial (UK, US)

Figure 21: Area menu.

Note

Currently no snapping to features is supported by measurement tools.

Print tool¶

The main idea is, that once print is activated in Gisquick, it means that before project publication is defined map composer in QGIS Desktop, it will download raw print output from QGIS Server using GetPrint request and will allow interactive visualization of map content directly in this template. One can zoom, pan and rotate map and see exactly how the result will look like. To get the better idea, see video below.

Important

Print tool in Gisquick is not accessible in Guest session, only log in users can use this tool.

User menu¶

User menu allows to:

Log out current user
Open user profile page
Enter/Leave Full Screen mode
Display attributions
Show Help (this document)
Show Project About (see Project publishing section)

Figure 22: Map attributions displayed.

User profile page¶

User page (My profile in User menu) allows managing published projects, and uploading new projects.

Figure 24: User profile menu.

In My Projects tab user can browse published projects including basic metadata. Project can open by clicking on its name.

Figure 25: List of published projects.

Tip

Project data are available also via WMS service, see WMS service link.

Action allows deleting project or updating table templates (see Table templates section for details).

Figure 26: Project actions menu.

In Upload Project tab new projects can be uploaded. Note that existing project will be automatically overriden. Projects can be uploaded in zip or tag.gz formats.

Note

See project size limits in Configuration section.

Figure 27: Upload project tab.

My account tab shows information about user account, see User management section.

Figure 28: Account information.

Another two menu items allows showing help page (this documenation) and log out the user.
