An Area Layer displays polygonal areas at an GeoAnalytics Map. The color can be controlled by a measure. The geometry is specified by a location ID that is looked up in a location service.
Dimensions / Measures
|Dimension||required||The ID Dimension represents an identity of the the area. It can also be used as the Location ID.|
|Location ID||default:||The Location ID of the area.|
|Color Value||default:||The measure that controls color.|
|Map ID||default:<the most recent map of the sheet>||Specify this value when there is more than one map on a sheet to tell which map to display the layer on. See Map Id in Map Settings of the Map to get the right one.|
|Max no. of Objects||default:1000||To display more than a thousand object increase this value. There will be a warning if there are more objects to display.|
|In Resolution Limit||default:0||The map will not be displayed when zoomed further in than this value. Check "Map.Debug.Show debug info" to see current resolution. The resolution is defined as meters per pixel, i.e. the number of meters each pixel covers.|
|Out Resolution Limit||default:99999999||The map will not be displayed when zoomed further out than this value. Check "Map.Debug.Show debug info" to see current resolution. The resolution is defined as meters per pixel, i.e. the number of meters each pixel covers.|
|Restrict Drill Down||default:||When the dimension is a drill down group it is possible to restrict the layer to be active only for a single level or multiple levels. This makes it easy to create different layers that are active in the different levels of the drill down. The top level is number 0. Multiple levels can be specified separated with comma. This property is ignored if the dimension is not a drill down group.|
|Include in Auto Zoom||default:Yes||Determines if the layer should be included when calculating area to zoom to when automatically zooming to selections.|
|Draw Order||default:Checked||Defines how the layer should be drawn compared to other layers, which ones should be drawn on top of each other.|
|Draw Order Category||default:<Layer specific>||The layers are by default drawn after the base map and the base map labels in the order Geodata Layers, Area Layers, Heatmap Layers, Line Layers, Bubble Layers. To make this layer draw in another category, adjust this value. This property is only visible when "Draw Order" is set to "Custom".|
|Draw Order Adjustment||default:0||Increasing this value makes the layer draw later, i.e. be more visible in the category. Allowed values are in the range -10 to 10. If you want the layer to be on top of other layers in the same category increase this value, if you want it to be overdrawn by other layers in the category decrease it. This property is only visible when "Draw Order" is set to "Custom".|
Location information is either specified as longitude, latitude pairs, as identities that are looked up in an external service or as sense geometries. When the term "Location ID" is used below it means it can be a sense geometry or an identity looked up else where. When it starts with a "[" it is assumed to be a geometry in a string ([long,lat] is a point, [[long1,lat1],[long2,lat2],...] is a line, [[[long1,lat1],[long2,lat2],...]] is a multi-line or a polygon with multiple rings, [[[[long1,lat1],[long2,lat2],...]]] is a multi-polygon but also accepted as a multi-line). The external service can be something as simple as a geometry file or a more complex server based service. The server based services provide a syntax for specifying more information on identities to minimize false hits. For instance containing areas and types of features can be specified. The following is the city Hamburg in Germany:
Hamburg,DEand this is Hamburg in Sweden:
Hamburg,SEIf you actually wanted the first order administrative area in Germany named Hamburg you also need to specify a type:
Hamburg:AADM1,DEYou can also specify multiple areas when needed. For instance in USA there are many Hamburg. To get the one in Arkansas specify:
Hamburg,AR,USSee Location Service Specification for more information on syntax to use. When there are unresolved names a warning is displayed in the upper left corner of the map.
|Location Service Type||default:Geometry service||The type of service used for location ID lookup.|
|Source Key Attribute||optional||The attribute in a geometry file to use as the location ID. This field is only visible when a file based geometry service is selected.|
|Advanced Location||default:false||The advanced location toggle controls whether to use Advanced Loction, in essence whether to use Location ID Suffix or to use Country and Type.|
|Country||default:any||The Country dropdown can be used to narrow down a lookup of a location id. Using Country is a simplified way of using Location ID Suffix (see below).|
|Type||default:any||The Type dropdown can be used to narrow down a lookup of a location id. Using Country is a simplified way of using Location ID Suffix (see below).|
|Location ID Suffix||default:||
The specified string is appended to all IDs.
This is a convenient way to specify more information to server based location services such as country code or type.
The alternative is to use an expression in the measure that appends extra information.
With the following suffix all items are specified to be cities in Sweden:
:P*,SESee Location Service Specification for more information on syntax to use.
This provides an easy fix for incorrect location IDs. To change them to something else use a syntax like:
"value1":"remapped value1", "value2":"remapped value2", ...
|Geometry Attribute||default:the_geom||The name of the attribute that contains the geometry (without name space). This field is only visible when Location Service Type is GML/WFS.|
|Reverse Coordinates||default:unchecked||Coordinates are expected in order latitude, longitude or Y, X. Check when coordinates comes in the other order. This field is only visible when Location Service Type is GML/WFS.|
|Color legend||default:Checked||Controls if visibility of the parts in the right side of the legend should be in Auto or Custom.|
|Show Colors||default:Checked||Turn on/off the color bar. This option is only visible when "Color legend" is Custom.|
|Show Color Min/Max Values||default:Checked||Turn on/off the text labels for color values. This option is only visible when "Color legend" is Custom.|
|Show Color Title||default:Checked||Turn on/off the label at the right side of the legend. This option is only visible when "Color legend" is Custom.|
|Show Icon Title||default:Checked||Turn on/off the label at the left side of the legend.|
|Show Icon||default:Checked||Turn on/off the area icon.|
|Colors Colors||default:Auto||In Auto the colors are mapped to values based on if there is a color measure and its type. The second measure after the location controls color. When set to Custom more options are displayed, see below.|
|Colors drop down||default:By Measure||Choose between "Single Color" "By Dimension", "By Measure" and "By Expression". "By Measure" is only displayed when there is a color measure. "By Expression" requires for technical reasons that there is at least one measure. Additional options are displayed for the particular choices.|
|Colors Transparency||default:0||A slider that controls transparency of objects from no transparency to invisible.|
|Outline Color||default:#aaaaaa||Determines outline color of features. If the field is empty the default value is used. All valid CSS colors can be used.|
|Show Label||default:unchecked||When checked, the label defined by the expression is displayed at each object.|
|Label||default:||An expression that is displayed as a label next to each object. Only visible when "Show Label" is checked.|
|Out Resolution Limit||default:99999999||The label will not be displayed when zoomed further out than this value. Check "Map.Debug.Show debug info" to see current resolution. The resolution is defined as meters per pixel, i.e. the number of meters each pixel covers. Only visible when "Show Label" is checked.|
Appearance: Info Bubble
|Show Info Bubble||default:Checked||When checked, a pop-up is displayed when hovering above the object.|
When set to Auto, the dimension and measures are displayed in the pop-up.
When Custom, an expression defines what should be displayed.
HTML tags can be used for formatting. For instance assuming there is a field [City Name]:
|Format Numbers||default:Checked||When checked, numeric values are rounded and displayed with suffixes such as k, M, G etc. Only visible when "Show Info Bubble" is checked.|
|Auto-Format Numbers||default:Checked||When Checked all numbers are formatted. When Unchecked, it is possible to specify which numbers should be formatted. Specify 1 for first number, 2 for second etc. Separate with comma. This option is only available when "Format Numbers" is checked.|
