Google Places API를 이용한 주변 지역 정보 검색

Open API/Google|2016.11.22 16:39



간만에 구글 API를 보던 중 재미난 샘플이 있어서 살짝 들여다 봤습니다.. 맛만..;;

화면 ui 및 기능 정리가 잘되어있어서 활용 범위가 클것같습니다.

Google Places 대신 자체 디비를 사용해서 쓰게되도 멋질것 같다는 생각이 듭니다.

( 메인은 Google Places 인데...어째 딴 생각이 드네요.)



아직 자세히 보지는 못해서 조만간 뜯어보고 싶네요.

복합적인 기능이다 보니 좀 단순화시켜서 개별 샘플화 하기!!

당장 하고 싶지만 일은 해야 하니까요 ㅠㅠ


보면 볼수록 구글의 방대한 데이터는..후덜덜하네요


Test Url : http://www.uhoon.co.kr/test/2253.html



대략 적인 기능은 


지역명 자동완성 기능 - Autocomplete

좌표 이동시 getBounds() 를 이용하여 화면내에 위치한 마커만 표시

PlacesService 로 지역정보 검색 등등.....
