???? No mistake, the vector slices are calculated using PostGIS. Before that, prepare a data: A GIS data table (point data of 1 million in this case, coordinates: 4326), and add X, y fields to the table to facilitate subsequent data filtering. The SQL uses theST_ASMVT and St_asmvtgeom.???? Creating a vector slice in this article is simple, using one of the following SQL to run the results like. Then write a vector slice of the HTTP service (refer to Go-vtile-example, this example, the vector til

Title: Given n building, the initial height of 0, each time can change the height of a building, for each change in height from the origin can be seen several buildingsRecord the slope of the connection between the roof and the origin of each building. The building is visible when and only the slope of all buildings in the current polygon is less than this building.Divide n buildings into √ (0.5*N*LOGN) blocks to maintain a monotonically ascending subsequence in each piece (note not LCS) For exa

In the Metro interface, we can see a lot of tiles and we'll loop through the information we've already browsed, as shown in the following illustration:If you want to clear the personal information in the tile, you can do the following:1. Under the Metro interface, press the keyboard "WIN" + "C" key combination to run the Super button. 2. Select "Settings". 3. In "Settings", select "Tile". 4. Click "Remove" under "Magnetic paste". 5. There will be a "c

Use Win+q key combination to enter the local application search, touch screen users with their fingers from the right side of the screen to the middle of the pull out the Super button select the "Search" Magnifier icon, in the search box input "gpedit.msc", click Search results; 2. Select "User Configuration" → "admin templates" → "Start menu and taskbar" → "clear the history of tile notice when exiting the system"; 3. Select "Enabled" in the open window and press "OK" or "app

need funds to continue development. If you use a software and like it very much, why don't you share a reasonable fee from the money it saves to developers? In this way, they may be more motivated to make the software more perfect. But it is an open-source world, and money doesn't mean everything: "I think many people prefer programming rather than money, and they need to be careful when dealing with money relationships in volunteer projects," Cox said.
