8.4 Digitizing and Editing Tools Figure 14: GRASS Edit Dialog 8.4.2. Category Tab This tab allows you to set the way in which the category will be assigned to each new feature and/or assign a category to a feature. • Mode: what category should be attached to geometry – Next not used - next category not yet used in vector file – Manual entry - define the category in the ’Category’-entry field – No category - digitize geometry without entering any category • Category - a number (ID) attached to digitized feature • Field (layer) - feature (attribute table) identification Tip 28 CREATING ADDITIONAL ’LAYERS’ WITH QGIS If you like to add more layers to your dataset, just add a new number in the ’Field (layer)’ entry box and press return. In the Table tab you can create your new table connected to your new layer. 8.4.3. Settings Tab This tab allows you to set the snapping in screen pixels. This is the threshold in pixels in which new points or line ends are snapped to existing nodes. This helps prevent gaps or dangles between QGIS 0.8 User Guide 55

The default is set to 10 pixels. 8.4.4. Symbology Tab This tab allows you to view and set symbology and color settings for various geometry types and their topological status (e.g. closed / opened boundary). 8.4.5. Table Tab This tab provides information about the database table for a given ’layer’. Here you can add, modify or create new database tables for the current layer. QGIS 0.8 User Guide 56
