地理信息系统（GIS）涉及空间数据的收集、管理、显示和分析。为了利用GIS，需要有适当的硬件、软件和训练有素的人员。然而，与数据收集的成本相比，自动化项目的这一部分的成本很小，而数据收集的成本非常昂贵。此外，不同应用程序所需的数据的准确性和质量通常也不尽相同。本文全面概述了在数据收集过程中遇到的不同类型的错误。概述了在数据收集的主要和次要方法中遇到的不同错误。
Geographic Information Systems (GIS) are concerned with the collection, management, display, and analysis of spatial data. In order to utilize GIS, one needs to have appropriate hardware, software, and trained personnel. However, the cost of this portion of an automation project is small compared to that of data collection, which is very expensive. Moreover, the accuracy and quality of data required for different applications is not usually homogeneous. In this paper, a comprehensive outline of the different types of errors encountered in the process of data collection is presented. An overview of different errors encountered in the primary and secondary methods of data collection is explained.
