주변 지역 검색

주변 지역 검색 (신규)은 하나 이상의 장소 유형을 취하여 일치하는 장소의 목록을 반환합니다. 다음 예에서는 장소 유형을 선택하고 지도에서 결과를 확인할 수 있습니다. 마커를 클릭하면 장소에 대한 자세한 내용을 확인할 수 있습니다.

주변 지역 검색(신규)은 지정한 장소 유형(예: restaurant, book_store, bowling_alley)을 기반으로 일련의 장소에 대한 정보를 반환합니다. 이 서비스는 지정된 locationRestriction의 반경 내에서 지정된 장소 유형과 일치하는 장소의 목록을 반환합니다.

주변 지역 검색(신규)을 사용하려면 Google Cloud 프로젝트에서 'Places API(신규)'를 사용 설정해야 합니다. 자세한 내용은 시작하기를 참고하세요.

주변 장소 찾기

지정된 장소 유형, 위치, 반경을 기반으로 장소 목록을 반환하려면 searchNearby()를 호출합니다. 요청을 사용하여 검색 매개변수를 지정한 다음 searchNearby()를 호출하세요. 결과는 Place 객체의 목록으로 반환되며, 이 목록에서 장소 세부정보를 얻을 수 있습니다. 다음 스니펫은 요청 및 searchNearby() 호출의 예를 보여줍니다.

TypeScript

// Get bounds and radius to constrain search.
center = mapElement.center;
let bounds = innerMap.getBounds();
const ne = bounds.getNorthEast();
const sw = bounds.getSouthWest();
const diameter = spherical.computeDistanceBetween(ne, sw);
const radius = Math.min((diameter / 2), 50000); // Radius cannot be more than 50000.

const request = {
    // required parameters
    fields: ['displayName', 'location', 'formattedAddress', 'googleMapsURI'],
    locationRestriction: {
        center,
        radius,
    },
    // optional parameters
    includedPrimaryTypes: [typeSelect.value],
    maxResultCount: 5,
    rankPreference: SearchNearbyRankPreference.POPULARITY,

  • fields 매개변수(필수)를 사용하여 하나 이상의 데이터 필드가 쉼표로 구분된 목록을 지정합니다.
  • locationRestriction 매개변수(필수)를 사용하여 최대 50,000미터의 반경을 지정합니다.
  • includedPrimaryTypes 매개변수를 사용하여 검색할 하나 이상의 장소 유형을 지정합니다.
  • rankPreference 매개변수를 사용하여 POPULARITY 또는 DISTANCESearchNearbyRankPreference를 지정합니다.
  • 매개변수의 전체 목록을 확인합니다.

다음 예에서는 searchNearby()를 사용하여 지도 경계 내에서 선택한 유형의 장소를 쿼리하고 지도를 마커로 채워 결과를 보여줍니다.
