Problems solved by technology
For field data survey and collection, staff often need to carry remote sensing images and corresponding office data to the field for data collection and editing; during data collection, since the screens of existing handheld mobile GIS terminals are mostly small, interactive methods It is relatively simple, and it is very difficult for field personnel to operate and collect GIS data on the screen with their fingers; if a mobile GIS terminal with a single interactive mode or cannot provide a complete collection and editing process module will directly affect the efficiency of data collection

The invention belongs to the technical field of geographic information methods, and discloses a GIS data acquisition method, which comprises the following steps of: creating an initial node, touchinga screen by a finger, and continuing drawing if the finger is within the range of the initial node; otherwise, judging whether the finger immediately leaves the screen after touching the screen, if so, drawing a node at the finger clicking position, and otherwise, storing the drawn node and rendering the current screen data; when drawing is continued, displaying, by the mobile terminal, a magnifier for assistance at the upper left corner of the screen within the range of the finger pressing node, if the other finger presses the screen simultaneously, drawing a single node, otherwise, drawing continuous nodes; when a node, a single node or a continuous node is drawn, starting an auxiliary tool used for adjusting the node; and when drawing of each node is completed, generating a geometric object according to the drawn node and displaying the geometric object on a screen. According to the method, the data acquisition process is more flexible and efficient, and various drawing modes included in the acquisition module can be randomly switched in the data acquisition process.
Description
technical field [0001] The present invention generally relates to the technical field of geographic information methods, in particular to a GIS data collection method. Background technique [0002] With the continuous development of mobile geographic information method GIS, the GIS data rendering, collection and editing platform based on the large amount of mobile terminal data is often used in field data survey and collection work. For field data survey and collection, staff often need to carry remote sensing images and corresponding office data to the field for data collection and editing; during data collection, since the screens of existing handheld mobile GIS terminals are mostly small, interactive methods It is relatively simple, and it is very difficult for field personnel to operate and collect GIS data on the screen with their fingers; if a mobile GIS terminal with a single interactive mode or cannot provide a complete set of collection and editing process modules i...
