Mantenha tudo organizado com as coleções
Salve e categorize o conteúdo com base nas suas preferências.
Para tornar os marcadores mais acessíveis, ative o processamento de eventos de clique, adicione
texto descritivo para leitores de tela e ajuste a escala do marcador.
Quando um marcador é clicável, ele pode responder ao teclado e ao mouse.
O texto especificado na opção de título pode ser lido por leitores de tela e aparece quando um usuário mantém o ponteiro do mouse sobre o marcador.
Aumentar o tamanho do marcador reduz a precisão necessária para interagir com ele em todos os dispositivos — especialmente, em dispositivos sensíveis ao toque — e melhora a acessibilidade. Os marcadores padrão atendem ao padrão de tamanho mínimo de WCAG AA, mas para desenvolvedores que buscam cumprir com o padrão de tamanho da área de WCAG AAA, o tamanho do marcador deve ser aumentado.
Confira no exemplo a seguir um mapa com cinco marcadores clicáveis e focalizáveis que
incluem texto de título e foram definidos para uma escala de 1,5x:
JavaScript

/* * Always set the map height explicitly to define the size of the div element * that contains the map. */html,map{height:100%;}body{height:100%;margin:0;padding:0;}
Faça o seguinte para navegar pelos marcadores usando o teclado:
Use a tecla Tab para selecionar o primeiro marcador. Se houver vários marcadores
no mesmo mapa, use as teclas de seta para mover entre eles.
Se o marcador for clicável, pressione a tecla Enter para clicar. Se ele tiver uma janela de informações, abra-o clicando ou pressionando a tecla Enter ou a barra de espaço. O foco retorna ao marcador associado quando a janela de informações é fechada.
Pressione "Tab" novamente para passar a outros controles do mapa.
Para melhorar a acessibilidade:
Defina o texto descritivo de um marcador usando a opção Marker3DInteractiveElement.title.
Adicione conteúdo ao espaço header de PopoverElement.
Aumente a escala do marcador usando a propriedade PinElement.scale.

Default markers meet the [WCAG AA minimum\n size](https://www.w3.org/WAI/WCAG22/Understanding/target-size-minimum.html) standard but for developers aiming to comply with the [WCAG AAA\n target](https://www.w3.org/WAI/WCAG21/Understanding/target-size.html) size standard the marker size should be increased.\n\nSee [basic marker\ncustomization](/maps/documentation/javascript/3d/marker-customization) to learn\nhow to change marker scale, add title text, and more.\n\nThe following example shows a map with five clickable, focusable markers that\ninclude title text, and have been set to 1.5x scale:\n\n\nJavaScript \n\n```javascript\nasync function initMap() {\n const { Map3DElement, Marker3DInteractiveElement, PopoverElement } = await google.maps.importLibrary(\"maps3d\");\n const { PinElement } = await google.maps.importLibrary(\"marker\");\n const map = new Map3DElement({\n center: { lat: 34.8405, lng: -111.7909, altitude: 1322.70 }, range: 13279.50, tilt: 67.44, heading: 0.01,\n mode: 'SATELLITE'\n });\n // Set LatLng and title text for the markers.
