Preliminary research topic: give the latitude and longitude range (rectangular or circular) quickly from the large quantities of latitude and longitude in batches to remove information points. The method currently taken from the database can be resolved, but the amount of information is limited. A lot of data appears

A map of the German version latitude and Longitude view tutorial : 1, first open the map website of the High German to you want to see latitude and longitude of the location of the right button, and then click " this is where ." 2, click " more ", and then click " Share ". 3, copy and open the " shared address .

According to the current location of the coordinate point is also latitude and longitude, find the database near 5 km or 10 km near the implementation of all information, after looking for information, it is my sophomore school, is to find the string length, math forgot, did not think math is so useful, math ah really use too much. Use what cosine, angle, radian all forget, but by looking for data, or reali

the South Pole, we can draw many large circles perpendicular to the earth's equator in the north and south directions. This is called the "longitude circle". The line segments that constitute these circles are called the meridian lines. In the year 1884, the international regulation adopted the longitude line of the Greenwich Observatory in the suburbs of London as the starting point for calculating the

Turn 　 How are these longitude determined? The earth is constantly spinning around its axis (the earth's axis is an imaginary line through both the north and the South Poles and the center of the Earth), and the Earth's waist draws a large circle perpendicular to its axis, so that every point on the circle is equal to the north and South poles, and this circle is called "the equator". At the north and south sides of the equator, many circles parallel
