4.5 Editing<br />

Tip 12 CONCURRENT EDITS<br />

This version of Q<strong>GIS</strong> does not track if somebody else is editing a feature at the same time as you. The last<br />

writer wins.<br />

Tip 13 ZOOM IN BEFORE EDITING<br />

Before editing a layer, you should zoom in to your area of interest first. This avoids waiting while all the vertex<br />

markers are rendered across the entire layer.<br />

To digitize the geometry, left-click on the map area to create the first point of your new feature.<br />

For lines and polygons, keep on left-clicking for each additional point you wish to capture. When<br />

you have finished adding points, right-click anywhere on the map area to confirm you have finished<br />

entering the geometry of that feature.<br />

The attribute window will appear, allowing you to enter the information for the new feature. Figure 6<br />

shows setting attributes for a fictitious new river in England.<br />
