Display Of Professional Marine Geology Maps Based On Mobile APP

In recent years,the rapid development of mobile Internet technology has made it widely used in all walks of life,further optimizing the way people work and live.Mobile GIS technology is a combination of geographic information system technology and mobile Internet technology,so that GIS no longer only exists on the PC or various professional devices,but can be combined with more other functions for mobile terminal devices such as mobile phones The above use not only enriches the usage scenarios but also lowers the usage threshold.This topic is derived from a part of the project of marine geological multivariate data fusion processing and sharing products.It is to combine literature and periodicals,news and other text materials in the project with image data obtained by geological survey survey calculation in the same APP to form shared resources.The APP is mainly divided into three parts: news periodical information viewing,map data viewing,and personal settings.All information is displayed in the form of a list on the news journal information viewing page,and supports pull-down refresh,pull-up loading and more functions;on the map data viewing page,it displays the image data obtained from the GIS server,and can also be displayed on the mobile The image data data in the downloaded offline map package is displayed,and it also supports zooming in and zooming out of the image data,as well as distance measurement and area measurement for manually selected points in the image data;the main support on the personal settings page is User account management functions,such as logging out and changing login passwords.In order to complete the functional development of the marine geology professional map display based on the mobile APP,this article elaborated from the related development status,related technology,module design,implementation process,functional testing and other aspects.This APP uses the Android platform as a development platform,using ArcGIS for Server and ArcGIS Runtime SDK for Android to implement map-related functions;using the ListView framework that comes with Android to implement related functions of news and journal informationpages;Information is stored;use Tomcat and Socket communication to realize data interaction between client and server.
