Baidu map api obtains latitude and longitude and city names, and map api obtains latitude and longitudeTo integrate Baidu API positioning, follow these steps: 1. Register a developer2: Apply for key3: Download the jar package4: Code integration first look at the effect:1: it is best to apply for a registered developer in advance. The review takes 1 or 2 days.2: I used Android Studio to apply for the key, so

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 to be slower. If the generation of text files based on the index to find should be able t

How are these cable cables determined? The earth is constantly rotating around the Earth's axis (the Earth's axis is a hypothetical line through the earth's north and south poles and the Earth's Center), draw a large circle perpendicular to the Earth's axis in the waist, so that every point in the circle is equal to the distance between the north and south poles. This circle is called the "Equator ". On the north and south sides of the Equator, draw many circles parallel to the equator, which ar

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 to the equator are drawn, that is, "weft ring

This circle is called the "Equator ". On the north and south sides of the Equator, draw many circles parallel to the equator, which are "latitude circles". The line segments that constitute these circles are called weft wires. We set the equator to zero
