before I intersect 2 feature classes of different scales (e.g. 1:200,000 soil map and 1:25,000 land use map), should I rescale them like how u would resample raster datasets to the same resolution before overlaying them together? If yes, how do I do so in ArcGIS? (I have ArcGIS10.1).
If the data is georeferenced, you do not need to rescale anything. However, you should be aware that your data sources have different spatial resolution and use a tolerance (20-50 m) to avoid sliver polygons due to this difference.
