If the user does not need to use high-definition images, the system provides an off-line map downloading function, and if the working area is far away and has no network signals, the working personnel can download the image map of the working area for standby in advance.
(1) And preparing raster data. Raster data (a topographic map, a geological map and a high-precision remote sensing image map) related to an investigation region are manufactured into a map slice (uniform format. tpk) through ArcMap and are imported into the system, and the raster data part in a data service module is served by the data serving as investigation reference data.
(2) Vector data preparation. The vector data (point and line surfaces) related to the investigation region are converted into kml/kmz through a tool and are imported into the system, and the data serve the vector data part in a data service module to serve as investigation reference data.
When the system needs to call the mobile terminal online map, the online map adopts two coordinate systems: the first is the national bureau of testing coordinate system (GCJ02), and the second is the Baidu coordinate system (BD 09). The coordinate system of the used data and the submitted result data generally adopts a WGS84 coordinate system, which has a deviation in position, in order to solve the problem, coordinate conversion is required to be performed to ensure the accuracy of data service, and the system needs to perform coordinate conversion when external data is imported, convert the data of the WGS84 coordinate system into GCJ02 or BD09, so as to solve the problem that the coordinates of the external data and the online map data are not matched. As shown in fig. 1:
the wgs84_ to _ gcj02, wgs84_ to _ bd09 methods are called as follows: the conversion method comprises the following steps:
(3) and downloading the offline map. The field investigation is hard, the investigation place is often not provided with a network, the online map cannot be loaded, and if the staff does not prepare the offline map (high-definition image map) of the working area, the user can download the offline map in the working range in the next day in advance, so that the information acquisition of the geological disaster point can be carried out when the user arrives at the area without the network.
Step 2: the geological survey information mainly comprises: and acquiring basic information (acquired by using a standardized template), multimedia information (photos and sound recordings) and point sketch (pictures) of the point.
(1) And (4) preparing for collection. Before formal collection is started, a worker needs to enter a system through a user name and a password, the system can manage a plurality of projects at the same time, the worker needs to create a new project name at first and then enters a first page of the project to operate, the first page takes a map and external data as backgrounds (an online map, the external data and an offline map), and the user can select different data types to perform map switching, map layer loading (a loaded map layer is superposed on the online map and transparency setting) and kml data import according to own needs.
(2) And collecting data according to the standardized template. The collected data are stored in an Sqlite database of the android system, and the database is a database with a standardized template, so that technicians are helped to reduce workload to a certain extent, and the result quality is improved. According to the method, 11 geological disaster information acquisition templates are formed according to geological disaster investigation standards in different fields and different degrees, the configurable form is realized, the form can be reused in geological disaster investigation projects of different types, the problem that an information acquisition system of the geological disaster investigation project of a mobile terminal needs customized development at present is solved, and the usability of the system is greatly improved. The specific flow is shown in FIG. 2;
(3) and (5) multimedia data acquisition. When information acquisition is carried out on a geological disaster point, the photographing and recording functions can be started, and the system numbers the photos and the records according to the roll call and the acquisition date of the geological disaster point. Although the function is simple to realize, the time for the workers to arrange photos in the field is greatly saved.
(4) The drawing board is used. Clicking the drawing board function, the system provides a painting brush function, a contour map of the collected points or a high-definition image map is used as a background, the rough range of the points is sketched, the rough range of the points and surrounding ground objects can form one of geological disaster results, namely a plane sketch, the system numbers the points according to the roll names and dates of the changed points, and workers do not need to sketch the plane sketch on site.
(5) And recording the track. And clicking a track recording function, recording the investigation route of the worker by the system, clicking an ending record, generating the investigation route, and exporting for later use in a format of a coordinate text file.
Similarly to data import, coordinate conversion is also required for exporting coordinate data, and data in a GCJ02 or BD09 coordinate system is converted into data in a WGS84 coordinate system, so that the accuracy of the exported data is unchanged and the exported data can be directly used. The derivation flow is shown in fig. 3.
The gcj02_ to _ wgs84, bd09_ to _ wgs84 methods are called as follows: the conversion method comprises the following steps:
(6) and (4) working cooperatively. When the system works in the field, the situation that a plurality of people investigate a geological disaster point at the same time may occur, after the acquisition of workers is completed, the workers click 'cooperative work', one member is selected, and the acquired information is combined to the member terminal.
And step 3: after the survey is finished, the survey results mainly comprise: standardized Excel forms, word cards, multimedia photos/recordings, sketches on a flat surface, survey tracks.
(1) And standard template data collected by field can be exported by clicking the function of 'collecting point result export'. The data is obtained by copying under a terminal-specified folder or network sharing (such as qq, WeChat, mail and the like). The exported data result generates Excel and word according to the fixed format in the specification, and workers do not need to spend time for sorting.
(2) Multimedia files are exported by clicking the functions of photo management, sound recording management and sketch management, and the part of data is also obtained by copying or network sharing (such as qq, WeChat, mail and the like) under a terminal-specified folder. The data are classified and numbered according to the disaster site and the date, and workers do not need to spend time for sorting.
(3) And (3) exporting the generated data in a format of a coordinate text by clicking a track recording function, and copying or sharing the data through a network (such as qq, WeChat, mail and the like) under a terminal specified folder to obtain the data, wherein the text coordinate data is general data of each large GIS platform. The staff leads the coordinate text into a professional GIS platform to generate a corresponding vector data line (survey line/track).
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
