Research And Development Of Field Data Acquisition Based On A New Development Model Using Both Android And Windows System

With the development of mobile GIS,the role of GIS in mobile data acquisition is becoming more and more important.After mobile data acquisition,there is standardized management through database,and output and display results according to specific project requirements.Therefore,the development of field data acquisition system is becoming more and more important.At present,the design of field data acquisition software is very diverse,and different industries have different standards and software to serve it,but these software development modes are similar,generally divided into two categories: one is to meet the consistency with the desktop,choose the mobile devices under Windows system to develop,and then meet the needs of the mobile side;the second is to develop mobile devices under Android or IOS systems for the powerful expansion of mobile devices.But these two development modes have certain disadvantages.The former needs external devices to meet the demand because mobile devices under Windows system generally have some deficiencies in expanding functions,but this is very cumbersome when using mobile devices;while the latter has powerful expanding functions such as GPS positioning,photography,direction sensor of mobile devices.Due to the insufficient hardware conditions of mobile equipment and the limitations of system development,it is difficult to meet or realize many requirements in software development.Desktop is far superior to mobile in development and database construction and management.But because desktop devices are generally not portable,they can not be carried and can not meet the requirements in the work.Therefore,this paper hopes to combine the powerful development advantages of the desktop side to assist and expand the development of the mobile end,hoping to achieve more powerful mobile end software development,and realize the development mode of " More Desktop,Less Mobile ".This paper hopes to discuss how the desktop side can assist the development of mobile terminal in the dual-terminal development mode,and from what aspects can the mobile terminal be "reduced" and "increased" in the development.In the research,first of all,we need to discuss and analyze the development architecture and database construction of the current mobile software model,so as to find out the requirements that can not be achieved or difficult to achieve in the current model and the existing problems,and then put forward the development architecture design of the development model that using both Android and Windows system;after the architecture design,we need to elaborate the development model in detail.The development model that using both Android and Windows system is improved in three aspects: the reduction of workload at the mobile end,the expansion of software functions at the mobile end and the consistency of data.Then,the function design of field data acquisition software is carried out by using the two-terminal development mode,hoping to meet the needs of these three aspects in the two-terminal mode.Finally,the mode is validated by an actual example to ensure that it can achieve "More Desktop,Less Mobile".
