Embodiment 1

[0057] This embodiment discloses a method for producing maps based on adaptive scale measurement and calculation, including the following steps:

[0058] Step 1: Read and symbolize one or more map data layers to be plotted;

[0059] Step 2: Create a framing range layer, and the framing range layer includes multiple drawing ranges;

[0060] Step 3: Set the size of the graph outline, and calculate a scale suitable for the size of the graph outline for each graph output range according to the multiple graph output ranges and the graph outline size;

[0061] Step 4: Based on the multiple drawing ranges and scales, perform framing and pre-drawing the picture to be confirmed by the user, and perform step 5 after the user confirms;

[0062] Step 5: Perform framing and outputting based on the plurality of outputting ranges, scales and symbolized map data.

[0063] In the step 2, the framing range layer is a line layer or a surface layer, and the drawing range is a polygon element or...

Abstract

The invention discloses a map dividing discharging method and system based on adaptive scale measuring and calculating. The method comprises the following steps: reading map data layers of one or moreto-be-discharged maps, and implementing symbolization; establishing a dividing range map layer, wherein the dividing range map layer comprises a plurality of map discharging ranges; setting a map border size, and calculating a scale corresponding to each map discharging range in accordance with the plurality of map discharging ranges and the map border size; and in accordance with the plurality of map discharging ranges, the scales and the map data obtained from symbolization, implementing map dividing discharging. According to the method and the system provided by the invention, rapid dividing discharging of a plurality of irregular charting areas can be achieved.

Description

technical field [0001] The invention belongs to the technical field of map drawing, and in particular relates to a method and system for map framing and drawing based on self-adaptive scale measurement and calculation. Background technique [0002] With the continuous advancement of technology, geographic information software such as ArcGIS has increasingly powerful functions in spatial data organization and spatial analysis, but there are still shortcomings in map making. The Data Driven Pages function in ArcGIS provides a convenient and quick tool for making map books. Based on ArcGIS, there are many application examples for framing map data of an area. For example, Luo Yanbin et al. used data-driven tools to compile standard framing maps for forest land protection and utilization planning; Wei Qiang et al. used data-driven tools combined with third-party plug-ins to complete automatic mapping of irregular map spots such as forest land. [0003] However, in the existing ...
