新加坡及其他地区的 twitter4j 地理流经纬度

Question

虽然它可能看起来与twitter4j geo streaming latitude/longitude for Hongkong 的问题相同，但事实并非如此。

我已经修改了 twitter4j 的流式示例代码并生成了这个：https://www.dropbox.com/s/gj75fghtqy5jajf/tweity.zip?dl=0

可以编译：

$ javac -classpath twitter4j-core-4.0.4.jar:twitter4j-media-support-4.0.4.jar:twitter4j-async-4.0.4.jar:twitter4j-examples-4.0.4.jar:twitter4j-stream-4.0.4.jar PrintFilterLocationStream.java

然后运行：

java -cp .:twitter4j-core-4.0.4.jar:twitter4j-media-support-4.0.4.jar:twitter4j-async-4.0.4.jar:twitter4j-examples-4.0.4.jar:twitter4j-stream-4.0.4.jar PrintFilterLocationStream "{{-126.562500,30.448674},{-61.171875,44.087585}}"

如果我得到正确的边界框，它工作得非常好，请参阅Can't get location filters to work using Twitter4J

但是对于新加坡，我已经从http://isithackday.com/geoplanet-explorer/index.php?woeid=24703045 查到了位置，但不知何故它抱怨它无效。

我也尝试过更大的盒子（"{{1,103},{2,104}}" 新加坡），但仍然无效。

我根据http://isithackday.com/geoplanet-explorer/index.php?start=malaysia 尝试在马来西亚使用"{{0.66364, 98.935059},{7.58378, 119.448433}}"，但它也无效。同样，印度尼西亚的"{{ -11.00485, 94.969833},{6.07573, 141.021805}}" 也不起作用 (http://isithackday.com/geoplanet-explorer/index.php?start=indonesia)。

• 新加坡的纬度/经度值应该是多少？

• 但是马来西亚或印度尼西亚呢？

• 是否有国家/城市的边界框列表？看起来很容易成为静态列表？

Answer 1

twitter4j 需要的坐标与http://isithackday.com/geoplanet-explorer/index.php?start=singapore 上显示的顺序相反...

新加坡是"{{103.618248,1.1158},{104.40847, 1.47062}}"

对于马来西亚，它是"{{98.935059,0.66364},{119.448433,7.58378}}"

对于印度尼西亚，它是"{{94.969833,-11.00485},{141.021805,6.07573}}"

除此之外，如果 http://isithackday.com/geoplanet-explorer/index.php 显示其他位置：

Bounding Box:
NE numA, numB
SW numC, numD

twitter4jFilterQuery.locations 期望：

{{numD,numC},{numB,numA}}
