Add style

Description	Adds a vector style.
Endpoint	/path/{pathId}/pointCloud/style
Method	POST

Access Level Rules

Minimum Access Level	edit+

Processing Units

Minimum processing units	2

Parameters

Name	Description	Required	Default
pathId	The id of the vector layer.	true
name	The name of the style to add.	true
parameters	The parameters JSON for the style. See details below.	true
default	Boolean whether the style should be used as the default styling of the timestamp.	true
method	The method of the style, should be 'v2' to use the most recent styling framework.	true
dryRun	Boolean whether to to only check the validity of the style without instead of creating it.	false	Default false.

The parameters JSON should follow the following schema:

{    //required
    "alphaMultiplier": 1,//A float between 0 and 1
    "radius":numberMapping, //A mapping that assigns a float
    "width":numberMapping, //A mapping that assigns a float
    "fill": colorMapping/iconMapping/patternMapping , //A mapping that assigns a hex color, pattern or icon
    //optional
    "popOver":{"color": colorMapping, "text":stringMapping}, //A mapping that assigns a string    
    "dashedLine":[number, number], //An array containing 2 numbers
    "borderColor":colorMapping, //A mapping that assigns a hex color
    "elevation":numberMapping, //A mapping that assings a value
}

Aside from the alphaMultiplier which should be a float, all properties in the parameters should be mappings. These mappings should be objects. There are a couple of mapping types you can use. All of these types are listed in the table below.

A mapping outputs a specific target based on the rules of the mapping in question. Targets can be of type string, number, color pattern or string. See below for documentation on how to define targets.

seededRandom

//Sent an expression to a seeded random color, this mapping can only be used to assign hex colors
{
    "type": "seededRandom", //should be seededRandom
    "expressionObject": {"expression":"2*property1+1", "properties":["myProperty"]} , //An expression to use as seed to create a random hex color
}

Expressions

Mappings can use expressions. An expressionObject is an object that consists of a properties and an expression.

expressionObject = {"expression":expression, "properties":properties, "values":values,

The properties should be an array of strings. Each element in the array should be the name of a property of the features within the layer that you are styling.

For example if your layer contains features with properties "constructionMaterial", "Height", and "housingType" then your properties array can be:

properties = ["housingType", "constructionMaterial","Height"]

The values should be an array of strings. Each element in the array should be any string value you want to use in the expression.

For example if your layer contains features with properties "constructionMaterial", "Height", and "housingType" then your values array can be:

values = ["flat", "concrete"]

The expression should be a string that can be interpreted as a formula or logical expression outputting either a number or boolean.

You can use the values of the properties array by referencing them as "property1", "property2",... and the values as "value1", "value2"...

For example:

expression="property1==value1 && property3>5"

Here property1 refers to the first element in the properties array which is in this case "housingType", the second to "Height" and value1 refers to the string "flat". That is to say the expression results in true for all features with housing type "flat" and altitude higher than 3 and false otherwise.

The expression can contain standard operators such as:

*,+,-,/, round(_), floor(_), ceil(_),),(

and logical operators such as:

&&, ||, not, ==,<=,<,>,>=,!=

An expressionObject can simply assign the value of a property:

expressionObject = {"expression":"property1", "properties":["housingType"]:, "values": []}

Or an expression can also simply be a number:

expressionObject={"expression":"1", "properties":[], "values": []}

Or boolean:

expressionObject ={"expression":"true", "properties":[], "values": []}

An expression can also be used to apply more complicated logic. For example finding the population density based on the properties "surfaceArea" and "population":

expressionObject = {"expression:"property2/property1", "properties":["surfaceArea", "population"], "values": []}

We can also make a more complicated logical expression:

expressionObject = {"expression":"property2!= 2 and property1 > 5", "properties":["surfaceArea", "population"], "values": []}

Target

A target is an object that can be of type color, pattern, icon, number or string. It signifies the value that is being assigned by the mapping.

In case of a colorMapping the target should be of type color, in case of a patternMapping of type pattern etc.

target = {type:"color/pattern/icon/number", "color":null, "pattern":null, "icon":null, "number":null}

Type color

In case of type color the target needs to contain a hex color:

target = {"type":"color", "color":"#99f53f"}

Type number

In case of type number the target needs to contain a number:

target = {"type":"number", "number":3.2}
