Recently, when I made a map, I thought about the color scheme and thought it was hard to see the color. So I learned from Google and opened the maps. google. com or local. google. com, the figure inside is really pretty nice.

Brief Preface
There are some fatal steps to make the Google map working. First of all, add a reference of Google Maps API in the head element:
Second, make the code run while page loading:
As you see, the last sentence code is most important. to initialize the object Map need two parameters, one is a HTML element which used to be a DIV, the other parame
| 24 | [PNG data]
5 | 15 | 25 | [PNG data]
This table is easy to query for a particular tile: for example, the query level is 8, the column number is 116, the row number is 192 of the tile data:
SQLite>SELECTfromWHERE=8and=116 and=192; [PNG data]
Tile_data is a binary stream file that can be easily read from the Mbtiles database, whether it's a desktop app or Android or iOS app.
Here is a demo program I made with Delphi:
