Yahoo is worse for the detail. In some places with many curves and meanderings I have been very rough with the trace. all of that work is marked source=landsat ABS data is imported. Where this corresponds to the river I have started using the ABS data to make the river more accurate. Neither of these are a field survey of any description, and the way still needs the ABS source attributed, so that in future when someone does follow the river with a GPS the river can be updated - it won't be marked source=survey so we will know it needs a field check. If the ABS tag is gone - how do I know to use this for an improvement on landsat ???
