Maps JavaScript API 提供兩種地圖導入方式:光柵與向量。系統預設會載入光柵地圖,並以像素為基礎的光柵圖片圖塊格線載入地圖,這些圖塊是由 Google 地圖平台伺服器端產生,然後提供給您的網路應用程式。向量地圖則是由向量圖塊組成,這些圖塊會在載入時使用 WebGL (一種網路技術,可讓瀏覽器存取使用者裝置上的 GPU,以算繪 2D 和 3D 圖像) 在用戶端繪製。建議使用向量地圖類型,因為這類地圖的視覺保真度較高,且可控制地圖的傾斜度和方位,提供最佳使用者體驗。進一步瞭解向量地圖功能。
如要設定地圖的算繪類型,請指定 renderingType 地圖選項,或在相關聯的地圖 ID 上設定選項。renderingType選項會覆寫透過設定地圖 ID 進行的任何算繪類型設定。
指定 renderingType 選項
使用 renderingType 選項,為地圖指定光柵或向量算繪類型 (不需地圖 ID)。如果是使用 div 元素和 JavaScript 載入的地圖,預設的算繪類型為 google.maps.RenderingType.RASTER。請按照下列步驟設定選項:renderingType

The raster map is loaded by default, and loads the map as a grid of\npixel-based raster image tiles, which are generated by Google Maps Platform\nserver-side, then served to your web app. The vector map is a composed of\nvector-based tiles, which are drawn at load time on the client-side using\nWebGL, a web technology that allows the browser to access the GPU on the user's\ndevice to render 2D and 3D graphics. The vector map type is recommended for the\nbest user experience, as it provides improved visual fidelity as well as the\nability to control tilt and heading on the map.\n[Learn more about vector map features.](/maps/documentation/javascript/vector-map)\n\nSet the rendering type for a map either by specifying the `renderingType` map\noption, or by setting the option on an associated map ID. The `renderingType`\noption overrides any rendering type settings made by configuring a map ID.\n\nSpecify the `renderingType` option\n----------------------------------\n\nUse the `renderingType` option to specify either the raster or vector\nrendering type for your map (no map ID required). For maps loaded using a `div`\nelement and JavaScript, the default rendering type is\n`google.maps.RenderingType.RASTER`. Take these steps to set the `renderingType`\noption:\n\n1. Load the `RenderingType` library; this can be done when loading the Maps\n library:\n\n const { Map, RenderingType } = await google.maps.importLibrary(\"maps\");\n\n2. When initializing the map, use the `renderingType` option to specify either\n `RenderingType.VECTOR` or `RenderingType.RASTER`:\n\n map = new Map(\n document.getElementById('map'),\n {\n zoom: 4,\n center: position,\n renderingType: RenderingType.VECTOR,\n }\n );\n\nWhen the vector map rendering type is set, you must set the options for the\nneeded features.\n\n- To enable tilt, set the `tiltInteractionEnabled` map option to `true` or call `map.setTiltInteractionEnabled(true)`.\n- To enable panning, set the `headingInteractionEnabled` map option to `true` or call `map.setHeadingInteractionEnabled(true)`.\n\nFor maps loaded using the `\u003cgmp-map\u003e` element, the default rendering type is\n`google.maps.RenderingType.VECTOR`, with tilt and heading control enabled. To\nset the rendering type by using the `\u003cgmp-map\u003e` element, use the\n`rendering-type` attribute.\n\nUse a map ID to set rendering type\n----------------------------------\n\nYou can also specify the rendering type by using a map ID. To create a new map\nID, follow the steps in [Using Cloud-based Map Styling - Get a map ID](/maps/documentation/javascript/styling#creating-map-ids).\nBe sure to set the Map type to **JavaScript** , and select an option (**Vector**\nor **Raster** ). Check **Tilt** and **Rotation** to enable tilt and rotation\non the map. Doing so will allow you to programmatically adjust these values, and\nalso lets users adjust tilt and heading directly on the map. If the use of tilt\nor heading will adversely affect your app, leave **Tilt** and **Rotation** un-\nchecked so users will not be able to adjust tilt and rotation.\n\nNext, update your map initialization code with the map ID you created. You can\nfind your map IDs on the\n[Maps\nManagement](https://console.cloud.google.com/google/maps-apis/studio/maps) page. Provide a map ID when you instantiate the map using the\n`mapId` property as shown here: \n\n```javascript\nmap = new google.maps.Map(document.getElementById('map'), {\n center: {lat: -34.397, lng: 150.644},\n zoom: 8,\n mapId: '\u003cvar translate=\"no\"\u003eMAP_ID\u003c/var\u003e'\n});\n```\n| **Important:** It is recommended to associate your map ID and API key with the same Google Cloud console project."]]
