Not significantly. All this shows is that the data to be imported is likely incomplete, i.e. there are a significant number of schools not included. It does not give any indication if the items in your data set actually exist in reality or not. Since you cannot tell this reliably from imagery alone this requires on-the-ground evaluation. If you don't evaluate the data in advance regarding this you will likely end up with a significant number of phantom schools that only exist as the result of a bookkeeping error of some sort. Experience from past imports tells that this kind of error is very persistent and significantly affects the map usability in the long term or in other words incorrect information in the database is much more harmful than missing information. On a general note: Usually this kind of assessment should be made very early in the planning stages of an import. From someone like you who has already proposed a significant number of imports here in the past i would expect this to happen naturally meanwhile. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Imports mailing list [email protected] https://lists.openstreetmap.org/listinfo/imports
