Problems solved by technology

The inventors have found that the screens of handheld mobile terminals (i.e. mobile GIS platforms) are usually relatively small. If the geometric objects are drawn by clicking, various problems affecting the efficiency of data collection will be encountered, and it usually takes several minutes to complete the drawing. Operational efficiency is relatively low, and may not be accurate

Embodiment Construction

[0063] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0064] figure 2 Be the flow chart of an embodiment of the data collection method that this application is used for mobile GIS platform, this method comprises the following steps:

[0065] Step S10, obtaining the track drawn on the touch screen of the mobile GIS platform;

[0066] The field personnel slide their fingers on the touch screen of the handheld mobile GIS platform and make graffiti actions (Actions) to form a track, and step S10 acquires the track. In the point-and-click data collection mode of the related technology, field personnel are required to click nodes (such as each vertex of a geometric object) with their fingers instead of sliding graffiti. The touch screen of the mobile GIS platfo...

Abstract

The invention provides a method for data collection of a mobile GIS (Geographic Information System) platform. The method comprises the steps of obtaining a track sliding across a touch screen of the mobile GIS platform; sampling continuous nodes on the track; generating a geometric object according to the continuous nodes; inputting the geometric object in a GIS. The invention also provides a device for the data collection of the mobile GIS platform. The device comprises an obtaining module used for obtaining the track sliding across the touch screen of the mobile GIS platform, a sampling module used for sampling the continuous nodes on the track, a generating module used for generating the geometric object according to the continuous nodes and an inputting module used for inputting the geometric object in the GIS. According to the method and the device, provided by the embodiment of the invention, data can be more flexibly collected by an outdoor worker.

Description

technical field [0001] This application relates to the technical field of geographic information systems, in particular, to a data acquisition method and device for a mobile GIS platform. Background technique [0002] figure 1 A schematic diagram showing a point-and-click data collection mode according to the related art. The mobile GIS (Geography Information System, geographic information system) platform is used for field data collection. In the mobile GIS platform of the related art, when the mobile GIS platform is used for outdoor work, every time the field personnel click on the screen, a node in the geometric object is added. This mode is called the click-type data collection mode. [0003] The existing business process of data collection in the field is generally to bring the data of the office to the field for surveying and mapping. For example, if it is found that a ground feature patch (polygon surface object, usually hundreds of points) processed by the office i...
