Because less data can be hidden on the small vector data set , its copyright is very difficult to obtain protection, and the data is vulnerable to attack, so a new double watermarking algorithm was proposed in this paper.
However, it may play a good role in verification of data integrity.
This article from the airspace and frequency domains discussed in terms of a small amount of data to vector data watermarking method for copyright protection based on vector data.

Data acquisition includes traditional structured data, such as numerical, characters, and semi-structured, unstructured data, such as documents, graphics, images, video, data flow, etc.
Big data has been thought as a data processing technology, mainly referring to large-scale data, data structures, high complexity and the strong correlation of data.
These collected data are divided into structured data, semi-structured and unstructured data, including numeric, character, etc. are structured data, and documents, graphics, images, video, data flow, etc. are semi-structured and unstructured data
Master database can be reconstructed down to the basic data, specialized data and external exchange data, and upward to form a data mart, to form multi-theme oriented data organization model finally
They study elements, time and spatial resolution, accuracy and precision of coordination mechanisms and methods of the data acquisition, in order to realize data organization, dimension reduction, extraction, themed applications for water services data, especially to meet the unstructured, semi-structured massive data processing needs

Studies have shown that: the past 10 years the average annual reduction rate of 0.72% Lixian County arable land, and the reduction since 2002, much faster, In the spatial region, most dramatic change is more economically developed society Liwu Town, Dabaichi Town, Xinxing Town and Liushi Town.
Characteristics analysis of dynamic change of cultivated land resources Time series characteristics analysis of the dynamic change of cultivated land resources From table 1,we can see that the cultivated area in Lixian County has been declining since 2001 began, until 2010, the total reduction of cultivated area of Lixian County was 3428 hm2, and the average reduction was about 343 hm2 annual, with an average annual decrease rate was 0.72%.
The last column data in Table 2 is obtained according to this formula, they can reflect the regional differences of cultivated land use change of each township in Lixian County very visually.
Driving forces analysis of dynamic change of cultivated land resources According to the thoughts and requirements of the principal component analysis, the data from 2001 to 2010 were selected as the base, combined with the collected data, 12 representative index were selected :X1 represents total population (million), X2 represents rural population (million), X3 represents GDP (million), X4 represents per capita GDP (yuan), X5 represents total retail sales of social consumer goods (million), X6 represents fixed asset investment (million yuan) , X7 represents the added value of first industry (million), X8 represents the added value of second industry (million yuan), X9 represents the added value of the third industry (million yuan), X10 represents grain yield(T), X11 represents net income of rural residents (yuan),X12 was the total power of agricultural machinery (10000 kW) [4].
Conclusion (1) During the decades(from 2001 to 2010), the cultivated land-use in Lixian County occurred a large variation, total cultivated area and per capita arable land both showed a decreasing trend, the average annual reduction rate was 0.72%, and the reduction accelerated since 2002

The goals of the automation of design, small size and light weight for the sprung parts are easily realized, and the protection of weight reduction, lower cost and less material reserve has also been gotten in the curtain wall project.
（1） Where [T] is the coordinate conversion matrix.The general stiffness matrix in global coordinate system [K] can be combined by laying each [k]e to corresponding node number.After the equations set between the general stiffness matrix in global coordinate system [K] and load array {R},[K]{q}={R},is established and resolved based on the special final condition, the data of displacement, strain and stress of above model can be easily obtained.
For more detailed,you can see [5]. 1.3 The optimal model of sprung parts 1.3.1 The objective function In order to achieve the goals of energy conservation and weight reduction, the best method is decreasing the volume of sprung parts by analyzed the structure of sprung parts.
The weight reduction in the project is 6258.6kg, and the decreased cost is $6462.
The goals of the automation of design, small size and light weight for the sprung parts are easily realized, and the protection of weight reduction, lower cost and less material reserve has also been gotten in the curtain wall project.

Those data would be used in the farming, salinization management and production prediction in the Northwest Tarim Basin.

Cost reduction, energy conservation and utilization of geothermal resources will reach higher levels.
The energy saving and emission reduction evaluation data as well as economic evaluation data show that the new heating mode is much better than before.

Hence, the accuracy of experimental data that obtained from traditional method is questionable and disputable.
