![]() ![]() Opening your Browser Dev Tools while you interact with an APEX Map will give you a very good idea of the process behind rendering a map. Check the two images below to see those two use cases: Not bad, right! However, there are some specific types of maps, where Raster formats are used and that is when satellite or aerial imagery is displayed. Rendering on end-user’s device requires more powerful hardware.High-resolution display on all zoom levels without increasing the file size.Smaller size - lower server space requirement.Here are some of the benefits of using Vector tiles and these are the reasons why APEX now supports it in the latest version: What format can the tile be? It could be a Raster format (like PNG) or a Vector format (like PBF).Just open the Browser Dev Tools on the Network tab and check for yourself. So you can imagine how many calls your application does for a single move of the map. Each tile is delivered using a seperate call. That's why when you zoom or drag, the browser makes a number of requests to a server to get the new set of tiles. First of all, the rendered maps are a collection of tiles and each zoom level is presented using a seperate set of tiles.All the types of maps currently supported in Oracle APEX are great for being presented using vectors. ![]() They eliminate the blur that you usually see for a second before the map is reloaded after zoom-in, zoom-out or drag. Why is this good news? Because vector tiles are faster to render, smaller in size, contain lots of information, not just graphical. The Map region can now use Vector Layers for improved display quality, especially on high pixel density displays. ![]()
