Question

虽然它可能与twitter4j geo streaming latitude/longitude for Hongkong看起来一样，但它不是。

我修改了twitter4j的流媒体示例代码并生成了这个代码：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

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，它的效果非常好，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检查了位置，但不知怎的，它抱怨它无效。

我也试过一个更大的盒子（新加坡"{{1,103},{2,104}}"），但它仍无效。

我已根据http://isithackday.com/geoplanet-explorer/index.php?start=malaysia尝试将"{{0.66364, 98.935059},{7.58378, 119.448433}}"用于Mlaysia，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？
但马来西亚或印度尼西亚呢？
是否有国家/城市的边界框列表？它看起来很容易成为静态列表？

Answer 1

twitter4j所需的坐标顺序与http://isithackday.com/geoplanet-explorer/index.php?start=singapore所示的相反...

对于新加坡，它是"{{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

twitter4j FilterQuery.locations期望：

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

twitter4j geo流媒体纬度/经度新加坡及其他地区
