Maps procedure
- Set scales
Using the tile pyramid grading rules in the “specification”, the data is relatively straightforward, so the front 13 scale is shown here. The scale can also be set according to the specific situation, the general principle is: the smallest scale to display the full map, the largest scale region content is more abundant. The increments from small scale to the large scale is 2 times. The function to set the display scale is “Range” > “Fixed Scale” in the “Map” tab.
| No. | Scale |
|---|---|
| 1 | 1:591658710.91 |
| 2 | 1:295829355.45 |
| 3 | 1:147914677.73 |

| 13 | 1:144447.93 |
- Adds region elements
The administrative divisions region is one of the necessary elements for a digital map.

- Adds road elements
(1)Adding roads. The roads with different levels need use different symbols to distinguish. It is consistent with actual situation that the roads with high level use wider linear symbols with thicker colors and the roads with low level use finer line symbols with lighter colors. You can click Resources > Line Symbol Library to select the road line symbols provided by system, you can also create it.

- Adds POI points
