As an early application of GIS industry, the land industry has saved a lot of resources, including data and functional resources. Through the construction of land information, resources have been sorted out, but because of the different GIS platform used in various provinces and cities, there is still a problem of inconsistent function interface and inconsistency of data format. For example a province uses is a platform, b format data, B province uses is the C platform, a format data; C Province may use the B platform, c format data ... 　　In turn, it leads to low service sharing and repeated construction in the same level or across the level of the land sector. In the "Land and Resources information" 10 ...

There are often misconceptions about the relationship between big data and cloud computing. 　　And they will be mixed up to say, do one sentence of a straightforward explanation is: cloud computing is the virtualization of hardware resources, large data is the efficient processing of massive data. Although the above sentence explanation is not very appropriate, but can help you to understand the difference between the two. In addition, if you do a more vivid explanation, cloud computing is equivalent to our computer and operating system, will be a lot of hardware resources virtualization after the allocation of use, in the field of cloud computing is now the boss of Amazon, can ...
