-A **layer** is a styled representation of data of a single type (for example fill, line, or symbol). Layers _can_ be a part of a component, but don’t _have_ to be.
+**图层**是一种类型（例如填充，线或符号）的数据的设计表现。 图层 _可以_ 是组件的一部分，但不_必须_是。
 
-Layers power your map's visualization. Without layers, you cannot see your data. You can create multiple layers from the same data and you can filter data by attributes for styling in a layer. You can also fill the canvas with a color or pattern which will apply across the whole world.

-#### Data sources
+#### 数据源
 
-Add a layer that contains specific shapes (polygons, lines, or points) that cover part of the map. A layer from data comes from custom data that you have added to your Mapbox account. See the [Geospatial data](/studio-manual/overview/geospatial-data/) section for more information on adding custom data.
-
-Each layer needs data to work with, otherwise the style rules would not be applied to anything. (The exception is a background layer &mdash; see the next section for more details). To specify data for the layer, choose a **Data source** from the list of available [tilesets](https://docs.mapbox.com/help/glossary/tileset) used in your map style (_Active sources_), as well as a list of tilesets that are in your account but not used in the current style (_Unused sources_). You can use the search box to find a tileset, or upload a new tileset with the **+ Upload** button.

+每个图层都需要使用数据，否则样式规则将不会应用于任何内容。(例外的是一个背景图层；有关更多细节，请参见下一节)。 要为图层指定数据，请从地图样式中使用的可用[瓦片集](https://docs.mapbox.com/help/glossary/tileset)列表中选择一个“数据源”（_主要 源数据_），以及在你帐户中但未在当前样式中使用的瓦片集列表（_未使用的数据源_）。你可以使用搜索框查找瓦片集，或使用 **+上传** 按钮上传新的瓦片集。

To reduce the number of sources needed, consider combining data before uploading and using filters in the style editor to create different layers from the same source.

+- `透明度`: 控制热力图图层的全局不透明度。
+- `半径`: 设置每个点的半径（以像素为单位）。 随着半径的扩大，热力图将变得更平滑且细节更少。
+- `权重`: 测量每个点对热力图外观的影响。默认情况下，热力图图层的权重为1，这意味着所有点的权重均相等。将权重属性增加到5的效果与在同一位置放置5个点的效果相同。你可以使用 **跨数据范围的样式** 和 **具有数据条件的样式** 选项来基于指定的属性设置点的权重。
 
-- `color`: Defines the heatmap’s color gradient, from a minimum value to a maximum value. You can adjust the density and color of each stop individually, as well as add and delete stops. For inspiration on color choices for your heatmap, try [Color Brewer](http://colorbrewer2.org/).
-- `opacity`: Controls the global opacity of the heatmap layer.
-- `radius`: Sets the radius for each point in pixels. As the radius number increases, the heatmap will get smoother and have less detail.
-- `weight`: Measures how much each individual point contributes to the appearance of your heatmap. Heatmap layers have a weight of one by default, which means that all points are weighted equally. Increasing the weight property to five has the same effect as placing five points in the same location. You can use the **Style across data range** and **Style with data conditions** options to set the weight of your points based on specified properties.
-- `intensity`: A multiplier on top of the weight property. Intensity is primarily used as a convenient way to adjust the appearance of the heatmap based on zoom level.
+- `强度`: 权重属性顶部的乘数。 强度主要用作基于缩放级别调整热图外观的便捷方式。

-##### Rate of change
+##### 变化率
 
-There are several different options for the rate of change:
+对于变化率有几种不同的选择:
 
-**Linear**: By default, the rate of change is `linear`, meaning a difference of one zoom level increment will increase or decrease a value by the same amount.
+**线性的**: 默认情况下，变化率是 `线性`的 ，这意味着一个缩放级别增量的数量将使值增加或减少相同的数量。
 
-**Exponential**: A linear rate of change can be logical for many properties, but since objects in perspective increase in size exponentially as they get closer, the `exponential` option allows ramps to have a different _base_, meaning that you can customize the curve of how much a zoom level increase affects a property change over time. For example, you might visualize the population of counties in a state by proportionally scaling the layer's `Color` property from yellow to red for populations between 0 and 10 million people.
+**指数的**: 线性变化率对于许多属性而言是合乎逻辑的，但是由于透视图中的对象随着距离的增大而呈指数增加，因此`指数`选项允许倾道具有不同的 _基础_ ，这意味着你可以自定义曲线的大小来了解缩放级别的增加会影响属性随时间的变化。 例如，你可以通过将0到1000万人之间的图层的 `颜色` 属性从黄色成比例地缩放到红色来可视化某个州的人口。
 
-**Cubic Bézier**: The `cubic-bezier` option interpolates using the cubic Bézier defined by the given control points. This can be used to create non-linear, non-exponential effects like the to CSS transition properties `ease-in` and `ease-in-out`.
+**贝塞尔曲线**: `贝塞尔曲线` 选项使用给定控制点定义的贝塞尔曲线进行插值。 这可以用来创建非线性，非指数效果，例如CSS过渡属性`ease-in`和`ease-in-out`。 
 
-**Step**: The `step` option produces discrete, stepped results by evaluating a piecewise-constant function defined by stops. This option is helpful if you want complete control over the property values used in defined intervals rather than interpolating values between stops. For example, you might visualize the population of counties in a state by assigning the color yellow to counties with less than 500,000 people, orange for 500,000-1,000,000 people, and red for counties with more than 1,000,000 people.
+**Step**: `step`选项通过计算一个由停止定义的分段常数函数来产生离散的、阶梯式的结果。如果要完全控制在定义的时间间隔中使用的属性值，而不是在节点之间进行插值，则此选项很有用。 例如，你可以通过将黄色分配给少于500,000人的州，将橙色分配给500,000-1,000,000人的州，将红色分配给人口超过100万的州，来形象化一个州的人口。

-#### Style across data range
+#### 跨数据范围的样式
 
-Style properties can be applied based on the value of a tileset field by choosing **Style across data range**. To use **Style across data range**, you must have a numeric data field for which you can create stops. This option is not available for every style property. For example, you can interpolate from data for the color of fill layers, but not for patterns.
+通过选择 **跨数据范围的样式** ，可以基于瓦片集字段的值应用样式属性。要使用**跨数据范围的样式**，必须具有一个数字数据字段，可以为其创建节点。不是每个样式属性都提供此选项。 例如，你可以从数据中插入填充图层的颜色，但不能插入图案。
 
-#### Style with data conditions
+#### 带有数据条件的样式
 
-Add conditional logic to your styles with **Style with data conditions**. Apply a style property to all features in a layer with a given data field value. The value in this field can be a `string`, `number`, or `boolean`. You can also use multiple values in each conditional statement.
+使用 **带数据条件的样式** 将条件逻辑添加到样式中。Add conditional logic to your styles with **Style with data conditions**. 将样式属性应用于具有给定数据字段值的图层中的所有要素。 此字段中的值可以是`字符`, `数字`, or `布尔值`。 
 
-For example, in the Mapbox Basic style, landuse types are styled by `class`. If `class` is equal to `park` or `pitch`, the feature's fill color is green. If the `class` of a feature is equal to `hospital`, the feature's fill color is pink. Another condition is applied if the `class` is equal to `school`, and there is a fallback value for any feature whose `class` field does not match any of the conditions (or does not exist at all).
+例如，在Mapbox Basic样式中，土地类型由`class`设置样式。 如果`class`等于`公园`或`运动场`，则特征的填充颜色为绿色。 如果要素的`class`等于`医院`，则要素的填充颜色为粉红色。 如果`class`等于`学校`，则应用另一个条件，并且其`class`字段与任何条件都不匹配（或根本不存在）的任何要素都有一个备选值。
