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
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
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",
"position": [
25.07938,
121.23484
],
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,

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
https://api.tomtom.com/search/2/poiSearch/桃園國際機場.json?countrySet=TWN&limit=2&key=API_KEY
也是通過考驗：

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...

在POI搜尋上，主要不是位置精準度問題
而是在中文語意搜尋上有分高下(事實上資料庫專長也不同)，如有需要可以稍加比較。
