Digital image data processing is mainly to input digital image data into a computer to complete the conversion of a continuous spatially distributed image model into a discrete digital model so that the computer can identify, process, and store the processing process of digital image information. Geographic information system (GIS) is a computer system that integrates multiple forms of information expression, and it integrates functions such as collection, processing, transmission, storage, management, analysis, expression, and query retrieval, which can quickly discover the spatial distribution of things and their attributes and can express the results accurately and vividly in various intuitive forms. Therefore, on the basis of summarizing and analyzing previous research works, this paper expounded the research status and significance of processing methods for digital image data, elaborated the development background, current status, and future challenges of the GIS technology, introduced the methods and principles of permutation matrix algorithm and subimage averaging method, constructed the processing model for digital image data based on GIS, analyzed the data structure and its database establishment for digital image, proposed the processing methods for digital image data based on GIS, performed the enhancement processing and calculation classification of digital image data, and finally conducted a case analysis and its result discussion. The study results show that the proposed processing methods for digital image data based on GIS can perform analogue-to-digital conversion of continuous images, complete the steps of sampling, layering, and quantization, and then encode the obtained discrete digital signal into the computer to form an in-plane collection of pixels; this processing method can also organically combine spatial information and image data and identify, process, and store digital image data from both spatial and attribute aspects. The study results of this paper provide a reference for further research on the processing methods for digital image data based on GIS.

Identification Phase

Data is the central element of a geographic information system (GIS) and its cost is often high because of the substantial investment that allows its production. However, these data are often restricted to a service or a category of users. This has highlighted the need to propose and optimize the means of enriching spatial information relevant to a larger number of users. In this chapter, a data enrichment approach that integrates recent advances in machine learning; more precisely, the use of deep learning to optimize the enrichment of GDBs is proposed, specifically, during the topic identification phase. The evaluation of the approach was completed showing its performance.

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. The acronym GIS is sometimes used for geographic information science (GIS science) to refer to the academic discipline that studies geographic information systems and is a large domain within the broader academic discipline of geoinformatics. GIS can provide the airport management staff with visual pavement information and powerful analysis tool. Meanwhile, the spatial information managed by GIS can ensure the accumulation of valid attribute data of airport. Based on the principle and general implementation process of GIS and the characteristics of airport pavement management, this paper describes the implementation process of GIS in Airport planning and design. To organize the spatial entities effectively, some layers are set according to the characteristics of spatial entities. The spatial database is established, and then the function design of the GIS software is presented including map exploring, map locating, spatial query, rendering style of map and output of map. Finally, in this paper, an overview of locating airports using GIS studied.

This paper puts forward the composition of geospatial information and its definition. The author designed and implemented the attendance management system based on Micro-cellular and the geographic information system (GIS) technology. The function of the geographic information system (GIS) was achieved by transforming Japan Geographical Survey Institute's Digital Map 2,500 base plate data into G-XML data. The function of location information system was accomplished according to micro-cellular mobile terminal-in the GIS's Real-time positioning and tracks. At last, the attendance management system based on micro-cellular and GIS technology was implemented by comparing the work schedule with the mobile tracks of its related mobile handheld terminals.
