5. Access geoserver from udig
Udig is an open-source desktop GIS software. Based on Java and eclipse platforms, You can edit and view SHP format map files. Its address is http://udig.refractions.net. Because you already have a Java environment, you can download the installation package and install it directly.

Let's take modifying a path as an example. Select the tasimania_roads_type layer and use the path editing tool on the toolbar. If you zoom in on the map, we will find that there is a road that overlaps with the water surface. You can correct it by modifying the position of a node.

If you want to cancel editing, you can use the rollback changes on the toolbar. After the modification is complete, Click Commit Changes on the toolbar. This is a typical transaction processing operation.

Then, open mapbuilder and the map has been modified.

Select the water layer in the source image, select all the water surfaces in the area selection tool box on the toolbar, copy and paste them to the new image. Select the roads layer, select all roads, and do the same.
