2.6. Vector layer styles

Styles describe a way of rendering for geodata and are one of the resources of NGW. Style is added to a map to display geodata.

2.6.1. Formats

By now NextGIS Web supports two rendering libraries: “Mapserver” и “QGIS”. You can write Mapserver style yourself as a text or import from QGIS styles, it has few settings. QGIS style you can only download from QGIS styles, it has much more settings.

2.6.2. Creation of style

Style is related to a single layer so there is no item “Style” in the main resources list. To create a style you need to open layer properties of the layer you want create style for. In actions pane “Create resource” click “MapServer style” or “QGIS style” (see Pic. 2.53.).

Pic. 2.53. Layer properties window.

In opened window you can import a QML style from QGIS or enter the style manually.

2.6.2.1. QGIS style

After the selection of “QGIS style” create resource dialog will open and will look like Pic. 2.54..

../../_images/ngweb_window_create_resource_eng.png

Pic. 2.54. Create resource dialog for QGIS style.

On the “Resource” tab enter the display name.

Field “Keyname” is optional.

You can also add resource description and metadata on the corresponding tabs.

Switch from “Resource” tab to “QGIS style” tab and in the “QML file” field click “Select a file” button or drag a file to this field (see in Pic. 2.55.).

To add a layer with QGIS style to a web-map navigate to home page (see in Pic. 2.4.) and select the web-map in child resources. To edit a web-map click pencil icon near it or click the web-map and in actions pane “Action” select “Update”. In “Update resource” layer select “Layers” tab (see in Pic. 2.57.).

../../_images/ngweb_select_styles_web_map_pic_eng.png

Pic. 2.57. “Layers” tab.

Here you can do the following actions:

  1. Add layer
  2. Add group
  3. Remove

Click “Add layer” and in opened window select a layer with QGIS style, then click “OK”. After that click “Save” (see in Pic. 2.58.).

2.6.2.2. MapServer layer

To create MapServer style open layer properties of the layer you want create style for (see in Pic. 2.53.). In actions pane “Create resource” click “MapServer style” (see in Pic. 2.54.).

Create resource dialog will open and will look like Pic. 2.60..

../../_images/ngweb_window_create_resource_mapserver_pic_eng.png

Pic. 2.60. Create resource dialog for MapServer style.

On the “Resource” tab enter the display name.

Field “Keyname” is optional.

You can also add resource description and metadata on the corresponding tabs.

Switch from “Resource” tab to “MapServer style” tab and click “Import QGIS style” or write a style manually (see in Pic. 2.61.).

../../_images/ngweb_create_resource_mapsrev_eng.png

Pic. 2.61. “MapServer style” tab.

Click “Import QGIS style” button and in opened window select a file or drag a file in opened field:

../../_images/ngweb_select_and_download_file_eng.png

Pic. 2.62. Selection of a file with QGIS style.

Warning

File to upload should be created in NextGIS QGIS and saved on the PC.

After the import click “OK” and then, after “Import QGIS style” window will close, click “Create”. When the process of creation will finish, the window of the file with MapServer style will open.

To add a layer with MapServer style to a web-map navigate to home page (see in admin_control_panel`) and select the web-map in child resources. To edit a web-map click pencil icon near it or click the web-map and in actions pane “Action” select “Update”. In “Update resource” layer select “Layers” tab (see in Pic. 2.57.).

Here you can do the following actions:

  1. Add layer
  2. Add group
  3. Remove

Click “Add layer” and in opened window select a layer with MapServer style, then click “OK”. After that click “Save” (see in Pic. 2.58.).

In actions pane “Web map” of web-map properties window select “Display”. The map will open, layers tree will be on the left of it. To hide/display a layer place a tick near the layer (see in Pic. 2.59.).

QML style will be converted to internal system format during import. Currently only basic geometry renderer settings are imported. If a style has a selection by query the empty option should be placed at the end (it is placed first after import from QGIS).

Warning

If you created a vector layer but MapServer style is absent in Create resource section check if you have installed nextgis_mapserver package. You can check this using “Package versions” (see in Pic. 2.4.) in Control panel (see item 1 in Pic. 2.2. and Pic. 2.3.).

You can create or edit a style of the layer using a manual input of a text or a code, or by editing an existing text/code (see details in ngw_mapstyles).

2.6.3. Map style tags

To change a style or to create a new one it is recommended you take a code of some existing style and then modify it, so there is no need to start creating a style from scratch.

2.6.3.1. Common tags

  • <color red=”255” green=”170” blue=”127”/> - the color of a fill or a line
  • <outlinecolor red=”106” green=”106” blue=”106”/> - outline color
  • <width>0.5</width> - a width of a line or an outline of the polygon.
  • <outlinewidth>3</outlinewidth> - outline width
  • <minscaledenom>1</minscaledenom> - do not display a feature if the map scale is larger than value
  • <maxscaledenom>100000</maxscaledenom> - do not display a feature is the map scale is less than value

2.6.3.2. Markers

../../_images/mapstyle_hatch_demo.png

Pic. 2.63. A demo for different hatches.

  • <symbol>std:circle</symbol> - marker type
  • std:rectangle - rectangle
  • std:circle - circle
  • std:diamond - diamong
  • std:triangle - triangle with peak at the top
  • std:triangle-equilateral - triangle with peak at the bottom
  • std:star - five-pointed star
  • std:pentagon - pentagon
  • std:arrow - arrow (by default is top oriented. Rotation could be set using a tag <angle>45</angle>)
  • std:cross - +
  • std:xcross - x
  • std:line - short line
  • std:hatch - long line texture

These markers could be used to draw a line, to fill a polygon or to display points. Also they may be combined to a complex symbol:

       <class>
           <expression>"industrial"</expression>
           <!-- Industrial areas -->
           <style> <!-- hatch with a right slope -->
               <color red="255" green="50" blue="50"/>
               <width>1.4</width>
               <symbol>std:hatch</symbol>
               <gap>10</gap>
               <size>5</size>
               <angle>45</angle>
           </style>
           <style> <!-- hatch with a left slope-->
               <color red="255" green="50" blue="50"/>
               <width>1.4</width>
               <symbol>std:hatch</symbol>
               <gap>10</gap>
               <size>5</size>
               <angle>-45</angle>
           </style>
           <style> <!-- Outline -->
               <outlinecolor red="255" green="50" blue="50"/>
               <width>0.5</width>
           </style>
</class>
  • <size>2</size> - marker size in pixels

2.6.3.3. Line features

  • <gap>10</gap> - a step size for dashed line (used with <symbol>std:circle</symbol>)
  • <width>8</width> - width of line in pixels
  • <classitem>PLACE</classitem> - filter by attribute PLACE. Also see example in #Filtering. The following operators are supported:
    • attribute name
    • !=
    • >=
    • <=
    • <
    • >
    • =* - case insensitive string comparison.
    • =
    • lt - less than
    • gt - greater than
    • ge - greater or equal
    • le - less or equal
    • eq - equal
    • ne - not equal
    • and - AND
    • && - AND
    • or - OR
    • || - OR
  • <linejoin>round</linejoin> - line draw at corners
  • <linecap>round</linecap> - line draw at the beginning and at the end
../../_images/admin_mapstyles_linecap.png

Pic. 2.64. <linecap>butt</linecap> / <linecap>round</linecap> / <linecap>square</linecap>

  • <pattern>2.5 4.5</pattern> - dash template
  • <angle> - marker rotation angle. Hatch could also be rotated.

2.6.3.4. Labels

  • <labelitem>a_hsnmbr</labelitem> - attribute name for labelling.

  • <minscaledenom>100</minscaledenom> - do not show a label if a scale is larger than 1:1000

  • <maxscaledenom>100000</maxscaledenom> - do not show a label if a scale is smaller than1:100000

  • LABELCACHE [on|off] - specifies whether labels should be drawn as the features for this layer are drawn, or whether they should be cached and drawn after all layers have been drawn. Default is on. Label overlap removal, auto placement etc… are only available when the label cache is active.

  • <position>ur</position> - label offset direction.

    • ur - ↗ up and right (recommended).
    • ul - ↖
    • uc - ↑
    • cl - ←
    • cc - centered
    • cr - →
    • ll - ↙
    • lc - ↓
    • lr - ↘
    • auto
  • <Maxoverlapangle> - ?

2.6.3.5. Some other useful tags

  • MAXGEOWIDTH - Maximum width, in the map’s geographic units, at which this LAYER is drawn. If MAXSCALEDENOM is also specified then MAXSCALEDENOM will be used instead.
  • MINGEOWIDTH - Minimum width, in the map’s geographic units, at which this LAYER is drawn. If MINSCALEDENOM is also specified then MINSCALEDENOM will be used instead.
  • OFFSITE - Sets the color index to treat as transparent for raster layers.
  • OPACITY [integer|alpha] - opacity of the layer
  • SIZEUNITS [feet|inches|kilometers|meters|miles|nauticalmiles|pixels] - Sets the unit of CLASS object SIZE values (default is pixels). Useful for simulating buffering.
  • SYMBOLSCALEDENOM [double] - The scale at which symbols and/or text appear full size. This allows for dynamic scaling of objects based on the scale of the map. If not set then this layer will always appear at the same size. Scaling only takes place within the limits of MINSIZE and MAXSIZE as described above. Scale is given as the denominator of the actual scale fraction, for example for a map at a scale of 1:24,000 use 24000.
  • TYPE [chart|circle|line|point|polygon|raster|query] - Specifies how the data should be drawn. Need not be the same as the feature geometry type. For example polygons or polylines may be drawn as a point layer.
