Produce Map Tile

With the development of map tile technology, SuperMap iDesktop keeps on developing and optimizing the production of map tiles and production efficiency. At present, iDesktop supports two functions to generate map tiles including Generate Map Tiles (Single-task) and Generate Map Tiles (Multi-task).

Generate Map Tiles (Single-task)

The Single-task feature could create one task on one computer to create map tiles.

Creating one task to produce map tiles is a traditional method that couldn’t utilize computer resources very well and applies to data in small size. For a big amount of data, the multi-task function is a good choice.

Generate Map Tiles (Multi-task)

In the era of big data, using one task to generate map tiles for a map with several scales (China map, for example) will be very time-consuming, which makes users unhappy.

How we can improve the generation efficiency of map tiles challenges us. To solve the problem, SuperMap iDesktop develops the feature multi-task which can use computer resources properly. You are allowed to create multiple tasks on one computer or multiple computers.

If you want to use multiple computers to generate map tiles, you should specify a shared directory that each computer can access. The multi-task function will divide a tile generation task into several child tasks and configure them into the shared directory. During the generating procedure, all computers will call child tasks from the shared directory and generating map tiles, which greatly improve the generation efficiency.

The efficiency of map tile generation will be affected by some factors including your computer performance, tile storage types, original data size, and storage position (local or remote folder). We have given some suggestions in the article Efficiency Comparisons of Multiple Tasks. You can refer to get a proper method to generate your map tiles.
