Hi,

I am trying to use Azure Map for geocoding cities and it looks like I am doing something wrong because the result is not really the one wanted.

Can you please help in getting a more accurate result?

I tried those two :

  • Tokyo (東京）

https://atlas.microsoft.com/search/address/json?api-version=1.0&query=%E6%9D%B1%E4%BA%AC&subscription-key=＜key＞

This works even it looks like a space is also added.

{"summary":{"query":"东 京","queryType":"NON_NEAR","queryTime":7,"numResults":3,"offset":0,"totalResults":3,"fuzzyLevel":1},"results":[{"type":"Geography","id":"TbOmYMFBz7Hm8q_lxc-oCA","score":1,"entityType":"Municipality","matchConfidence":{"score":1},"address":{"municipality":"Tokyo","countrySubdivision":"Kanto","countrySubdivisionName":"Kanto","countryCode":"JP","country":"Japan","countryCodeISO3":"JPN","freeformAddress":"Tokyo, Kanto"},"position":{"lat":35.68696,"lon":139.74946},"viewport":{"topLeftPoint":{"lat":37.14388,"lon":138.37411},"btmRightPoint":{"lat":34.89988,"lon":140.87509}},"boundingBox":{"topLeftPoint":{"lat":37.14388,"lon":138.37411},"btmRightPoint":{"lat":34.89988,"lon":140.87509}},"dataSources":{"geometry":{"id":"00005858-5800-1200-0000-00007d30cf7f"}}},{"type":"Cross Street","id":"RLcuh7f4vyzt6tP2jvxoyQ","score":0.8436848116464776,"matchConfidence":{"score":0.8436848116464776},"address":{"streetName":"Jingji 7th Road & Bade East Road","municipalitySubdivision":"Renwu District","municipality":"Kaohsiung City","countrySubdivision":"Kaohsiung City","countrySubdivisionName":"Kaohsiung City","postalCode":"814","countryCode":"TW","country":"Taiwan","countryCodeISO3":"TWN","freeformAddress":"Jingji 7th Road & Bade East Road, Renwu District, Kaohsiung City 814","localName":"Renwu District"},"position":{"lat":22.68506,"lon":120.34094},"viewport":{"topLeftPoint":{"lat":22.68596,"lon":120.33997},"btmRightPoint":{"lat":22.68416,"lon":120.34191}}},{"type":"Cross Street","id":"V-K9YrxqigrEdeIIjxcGHg","score":0.8453314176137078,"matchConfidence":{"score":0.8453314176137078},"address":{"streetName":"Jingji 6th Road & Bade East Road","municipalitySubdivision":"Renwu District","municipality":"Kaohsiung City","countrySubdivision":"Kaohsiung City","countrySubdivisionName":"Kaohsiung City","postalCode":"814","countryCode":"TW","country":"Taiwan","countryCodeISO3":"TWN","freeformAddress":"Jingji 6th Road & Bade East Road, Renwu District, Kaohsiung City 814","localName":"Renwu District"},"position":{"lat":22.68556,"lon":120.342},"viewport":{"topLeftPoint":{"lat":22.68646,"lon":120.34103},"btmRightPoint":{"lat":22.68466,"lon":120.34297}}}]}
  • Yokohama（横浜）

https://atlas.microsoft.com/search/address/json?api-version=1.0&query=%E6%A8%AA%E6%B5%9C&subscription-key=＜key＞

This result is as following, space in the query, city is found in HongKong and not Japan:

    Hi Fred,

    Can you please try our V2 Geocoder? V1 does not have good coverage for Asia and you are likely to get better results from V2. V2 has the version number as a date. See https://learn.microsoft.com/en-us/rest/api/maps/search/get-geocoding?view=rest-maps-2024-04-01&tabs=HTTP for the sample calls and parameter details.

    Also, you will get better answers if you give more context. For example, "Yokohama" vs "Yokohama, Japan". If you can give the city and country, the Geocoder will have greater information to narrow down the options.

    Sincerely,

    IoTGirl
