Editing a Layer
MapWindow supports basic capabilities for editing spatial data. Before performing any edits, always make a backup of the dataset the user is about to edit. Key files to copy when backing up a shapefile include any files ending in .prj, .dbf, .shp, and .shx.
To edit an existing layer, highlight the layer in the legend.
- Add features by clicking on the 
[Add Shape] icon and moving the cursor to the point to be added.
- Enter x, y (point) values by left clicking on the location where a point or vertex should be added.
- To move a point, click on [Move Vertex] 
icon, then select the point to be moved by left-clicking on it, then drag the selected point to the correct location and release the mouse button.
- To delete a shape from the shapefile, first click the 
Select icon from the toolbar. Next, select one or more shapes to be deleted with the mouse. They will change colour to indicate they’re selected now, click the 
Delete Shape button. The user will be asked if the user is sure; after answering [Yes] the shape(s) will be deleted.
- If the shapefile being created is a Polygon or a line, the user can add or remove a vertex from the existing shapefile using the 
[Add Vertex] or 
[Remove Vertex] buttons.
