Embodiment Construction

[0033] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0034] The method provided by the invention can use computer software technology to realize the process. see figure 1 , figure 2 and image 3 Since querying the latitude and longitude information of neighborhood committees using inverse geocoding belongs to the data preparation stage, the embodiment takes a process of sampling and evaluating results as an example to specifically illustrate the process of the present invention.

[0035] Step 1: Import the experimental data jwhsampling.shp and area.shp in sequence on the software interface to realize the sp...

Abstract

The invention discloses a spatial sampling method for social survey data. Firstly, samples are obtained through layered spatial sampling; then, a spatial point pattern analysis method is used to judge equilibrium of sampling result distribution according to a parameter calculation result; and if spatial equilibrium requirements are not met, re-sampling is carried out until a sampling result meeting the spatial equilibrium is obtained. Spatial sampling, spatial equilibrium evaluation and social survey are organically combined, thereby realizing effective cohesion between non-spatial data and spatialization technology. The traditional sampling method is improved, and a good auxiliary support is provided for social survey. Through visualizing the sampling result, a more intuitive visualized result is provided, and more accurate judgment can be obtained through spatial equilibrium evaluation.

Description

technical field [0001] The invention belongs to the field of spatial humanities and sociology, and relates to a spatial sampling method, in particular to a spatial sampling method of social survey data. Background technique [0002] Geographic Information System (GIS) technology is widely used in natural science fields such as modern surveying and mapping, national defense and military affairs, and field data collection, and is gradually applied in sociological fields such as social investigation, history, and culture. GIS has the capabilities of data synthesis, geographic simulation and spatial analysis. In the process of social survey and data analysis, using GIS technology to assist traditional sampling method is an important research topic of spatial sociology. [0003] Sampling is a preliminary means of social surveys. Through scientific sampling methods, the samples to be investigated are determined to make the samples more scientific, accurate and representative, so ...
