1. Experiment description
When editing geographic data, you often encounter individual or large numbers of holes in polygon data. Considering the number and distribution of holes in the actual situation, you can fill the hole areas one by one or in large batches quickly. Filling methods: ① Fill one by one : manually merge and fill each hole; ② Batch filling : draw a sketch surface that can cover all graphics areas to achieve fusion. Through experimental exercises, readers should be able to deeply understand the processing methods of the two methods and master the method of filling surface voids.
2. Experimental data
Open the software and load 0102.rarthe vector linear data in the experimental supporting data. You can see that there are many broken tooth polygons in the surface data, as shown in the following figure:
