| 55 | | When using imagery, keep in mind that imagery may be offset. That is, due to complexities in processing satellite imagery, features on imagery may not be at the same location as they are in the real world. For reference, check existing features on the map and compare them with the imagery or download GPS tracks. To download GPS tracks from OpenStreetMap, check the "Raw GPS" box in the download dialog. If you observe an offset in the imagery, you can correct for it by selecting the "New offset" item in the "Imagery" menu. |
