自我挑戰組

30天探索物聯網時代的地圖應用系列 第 6

Day06 POI

前一天提到的Geocoding,是指從門牌中換算坐標
而在昨天測試的服務中也看到,這些服務不只門牌,也包含了地標POI

於是今天就來測試看看POI

選手1

首先登場的選手是Google,用的API跟昨天一樣(很方便)
基本題搜尋桃園國際機場

https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=桃園國際機場&inputtype=textquery&fields=formatted_address,name,rating,opening_hours,geometry&key=API_KEY

嗯,難不倒:

{
    "candidates": [
        {
            "formatted_address": "33758台灣桃園市大園區航站南路9號",
            "geometry": {
                "location": {
                    "lat": 25.0796514,
                    "lng": 121.234217
                },
                "viewport": {
                    "northeast": {
                        "lat": 25.10275,
                        "lng": 121.2624304
                    },
                    "southwest": {
                        "lat": 25.05372919999999,
                        "lng": 121.2032256
                    }
                }
            },
            "name": "臺灣桃園國際機場",
            "rating": 4.1
        }
    ],
    "status": "OK"
}

第二題,搜尋臺北市政府

https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=臺北市政府&inputtype=textquery&fields=formatted_address,name,rating,opening_hours,geometry&key=API_KEY

結果:

{
    "candidates": [
        {
            "formatted_address": "11008台灣台北市信義區市府路1號",
            "geometry": {
                "location": {
                    "lat": 25.0375417,
                    "lng": 121.5644327
                },
                "viewport": {
                    "northeast": {
                        "lat": 25.03888107989272,
                        "lng": 121.5664671
                    },
                    "southwest": {
                        "lat": 25.03618142010728,
                        "lng": 121.5625935
                    }
                }
            },
            "name": "臺北市政府",
            "opening_hours": {
                "open_now": false
            },
            "rating": 3.8
        }
    ],
    "status": "OK"
}

也沒問題,

再給一點變化,變成台北市政府

https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=台北市政府&inputtype=textquery&fields=formatted_address,name,rating,opening_hours,geometry&key=API_KEY

結果:

{
    "candidates": [
        {
            "formatted_address": "11008台灣台北市信義區市府路1號",
            "geometry": {
                "location": {
                    "lat": 25.0375417,
                    "lng": 121.5644327
                },
                "viewport": {
                    "northeast": {
                        "lat": 25.03888107989272,
                        "lng": 121.5664671
                    },
                    "southwest": {
                        "lat": 25.03618142010728,
                        "lng": 121.5625935
                    }
                }
            },
            "name": "臺北市政府",
            "opening_hours": {
                "open_now": false
            },
            "rating": 3.8
        }
    ],
    "status": "OK"
}

可以看得出來,資料庫存的是臺北市政府,但Google在語意網搜尋上很強,easy

選手2

緊接著,第二個選手
先測試第一題:

https://places.cit.api.here.com/places/v1/autosuggest?at=23,121
&q=桃園國際機場&app_id=APP_ID&app_code=APP_CODE

結果也是沒問題,資料庫存的不一樣,但是沒啥問題:

{
    "results": [
        {
            "title": "Taiwan Taoyuan International Airport (臺灣桃園國際機場)",
            "highlightedTitle": "Taiwan Taoyuan International Airport (臺灣桃園國際機場)",
            "vicinity": "9, 航站南路, 大園區, 桃園市",
            "highlightedVicinity": "9, 航站南路, 大園區, 桃園市",

            ],
            
            略

第二題,測試臺北市政府

https://places.cit.api.here.com/places/v1/autosuggest?at=23,121
&q=臺北市政府&app_id=APP_ID&app_code=APP_CODE

結果如下:

{
    "results": [
        {
            "title": "政府 near Taipei City, Taiwan",
            "highlightedTitle": "<b>政府</b> near Taipei City, Taiwan",
            "category": "government-community-facility",
            "position": [
                25.03737,
                121.56355
            ],
            "href": "https://places.cit.api.here.com/places/v1/autosuggest/search;context=Zmxvdy1pZD00OWZjMThiYy0zNTlmLTUxYWItODVhMi1mY2ZmNDUyNTQyNjZfMTU2OTE2MDM5NDM2NV85MjA1XzM1MjgmcmFuaz0wJmF0PTIzLjAlMkMxMjEuMA?filters=lon%3A121.56355%2Ccategory%3Agovernment-community-facility%2Cvi%3Aautosuggest%2Clat%3A25.03737&app_id=APP_ID&app_code=APP_ID",

        },

            "highlightedVicinity": "96, 延平南路, 光復里, 台北市",

                25.04388,
                121.50982

略..

其實上面回應給了很多位置,但第一個建議的位置是差不多的(但可以看得出來中文搜尋還是有差)

接下來,直接上場地三位選手

                }
            }
        },

值得注意的事,細看資料發現不僅提供搜尋,還提供了其他資訊(如出入口等,我們過幾天討論)

一樣再測試臺北市政府

https://api.tomtom.com/search/2/poiSearch/臺北市政府.json?countrySet=TWN&limit=4&key=2GKtkrIduHYwsYmAIZjqeRc0f7YEIbYk

結果發現,語意搜尋上也是沒有那麼準,但至少有找到...
