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
).
Content management tools¶
Basic project metadata - project description - is accessible by question-mark, see figure below.
Content management widget is split into three major tabs:
Base Layers
Overlay Layers
Legend
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.
Overlay Layers
tab allows switching between topics (layer groups),
see Project publishing section, or
controlling overlay layers one by one.
In Layers
mode the overlay layers can be switch on/off one by one.
Todo
Explain legend.
Attribute data¶
In Layers
mode attribute data can be accessed by
. Attribute table is displayed in bottom part, see
figure below.
Attribute table allows filtering data based on simple queries, see figures below.
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.
Todo
Explain info panel.
Zoom tools¶
Zoom tools enables controlling map view.
Tip
Zooming and panning is also possible by middle mouse button.
Tools¶
Two basic tools are available:
Identify¶
By default, features are identified in all visible layers (in the example below in Schools and District layers).
This settings can be changed in Identification
combo box.
Measurement¶
Three measurement modes are available:
Location (point coordinates)
Distance
Area
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”.
Distance menu allows:
Zoom to distance
Change units. Currently two systems are supported: international (EU) and imperial (UK, US)
Area menu allows:
Zoom to distance
Change units. Currently two systems are supported: international (EU) and imperial (UK, US)
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.
