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.
- Enter x, y (point) values by left clicking on the location where a point or vertex should be added. For line or polygon features, continue left-clicking to add additional vertices, then right-click to finish editing the feature.
- 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.
