Measurement results FreeMarker template error (DEBUG mode; use RETHROW in production!): The following has evaluated to null or missing: ==> resource.content.area [in template "area.ftl" at line 22, column 46] ---- Tip: It's the step after the last dot that caused this error, not those before it. ---- Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)?? ---- ---- FTL stack trace ("~" means nesting-related): - Failed at: #if resource.content.area != -1 [in template "area.ftl" at line 22, column 41] ---- Java stack trace (for programmers): ---- freemarker.core.InvalidReferenceException: [...

highlightImage

Description:
Generates highlight image according to query result or highlight target set.

Image parameters:
Center: {"x": 0.0 ,"y": -3.19 }
Scale: 0.00000000169016
View bounds:

Left bottom: {"x": -180.0 , "y":-183.19 }
Right top: {"x": 180.0 , "y":176.81}

Size:

Width: 256
Height: 256

Highlight target set ID *		The highlighted target set resource to be mapped, which is the ID of the highlightTargetSet resource. When the Query result parameter has value, this parameter can not use.
Query result *		The query result resource to be mapped, which is the ID of the queryResult resource. When the Highlighted target set ID parameter has value, this parameter can not use.
Center		Specifies the center point of the map to display.
Scale		Specifies the scale of the map to display.
Width		Specifies the width of the user display window, which is the width of the generated picture. It needs to be used together with the Height parameter.
Height		Specifies the height of the user display window, which is the height of the generated picture. It needs to be used together with the Width parameter.
Output formats		Specifies the output format used to return map picture information.
Target projection		Coordinate reference system of the map. When the coordinate system set by this parameter is different from the original coordinate system of the map, the system will perform dynamic projection and return the map image after dynamic projection.
