Line Layer

A Line Layer displays lines from a start point to an end point at an GeoAnalytics Map. Line width and color can be controlled by measures. The positions for start and end can be specified either as location ids (common names such as country codes, state codes, city names, postal codes etc) or latitude, longitude values.

ID

An identity of the the line.

From, To, Width Value

When location IDs are used for start and end point (see Location Options), measures are specified in the following order:
  • Location ID for start point
  • Location ID for end point
  • Measure that controls line width (optional)
When location IDs are used for the entire (poly)line (see Location Options), measures are specified in the following order (it is also possible to specify the location id in the dimension):
  • Location ID for line
  • Measure that controls line width (optional)
If coordinates are used for start and end point measures are specified in this order:
  • Latitude for start point
  • Longitude for start point
  • Latitude for end point
  • Longitude for end point
  • Measure that controls line width (optional)

Layer Options

Parameters for Layer Options
PropertyUseDescription
Map IDdefault:<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.
Maximum Number of Objectsdefault:1000 To display more than a thousand object increase this value. There will be a warning if there are more objects to display.
Calculation Conditionrequired To limit when the layer is shown you can enter a caluclation condition as an expression. The layer is calculated/shown only when the expression is fulfilled.
Calculation Condition Messagerequired A custom error message that will be displayed in the layers legend if the calculation condition is not fulfilled. Only visible if a calculation condition has been entered.
Zoom Limitdefault:Min 0, Max 160000 The layer will not be displayed when zoomed further in/out than these values. To set a limit to the current scale, drag the upper or lower limit towards the other and it will snap to the current scale.
Restrict Drill Downdefault:0-16 When the dimension is a drill down group it is possible to restrict the layer to be active only for a a range of 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. The range selected specifies at what levels the layer should be visible.
Include in Auto Zoomdefault:Yes Determines if the layer should be included when calculating area to zoom to when automatically zooming to selections.
Draw Orderdefault:Auto Defines how the layer should be drawn compared to other layers, which ones should be drawn on top of each other.
Draw Order Categorydefault:<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 Adjustmentdefault: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 Options

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,DE
and this is Hamburg in Sweden:
Hamburg,SE
If you actually wanted the first order administrative area in Germany named Hamburg you also need to specify a type:
Hamburg:AADM1,DE
You can also specify multiple areas when needed. For instance in USA there are many Hamburg. To get the one in Arkansas specify:
Hamburg,AR,US
See 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.
Parameters for Location Options
PropertyUseDescription
Location Sourcedefault:Auto Where location information comes from.
  • Auto - Automatic determination of location source based on available measures and their types.
  • Latitude, Longitude measures - Latitude and longitude values are provided in first two measures. For lines also the third and fourth measures are used as end point. This option is only available for point geometries (including start and end points for lines).
  • Dimension - The dimension is the location id. This option is only available for point geometries (not lines or areas).
  • Measure - The first measure is the location id. For lines there are two measure alternatives; One for a single location id for the entire polyline and one for using the first measure for the start point and the second for the end point.
Location Servicedefault:different for different types of geometries URL to the location service. Either a server based service or a file as specified in "Location Service Type". An expression is accepted which makes it possible to change source dynamically. This can be used for switching file in different drill down levels for instance. Note that when a file is loaded, it is always loaded via the GeoAnalytics server (as a proxy) to avoid javascript restrictions on cross-origin loading.
Location Service Typedefault:Geometry service The type of service used for location ID lookup.
Source Key Attributeoptional 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 Locationdefault: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.
Countrydefault: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).
Typedefault: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 Suffixdefault: 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*,SE
See Location Service Specification for more information on syntax to use.
Manual Remapdefault: 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 Attributedefault: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 Coordinatesdefault: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.
