I had a quick glance through the files.
*Nodes*: Quite a bit of very useful and mostly new POI's. Schools,
colleges, hospitals, religious places, hotels, neighborhoods. The pois look
like they can be uploaded into osm and are worth the effort. You can use
the following filter in josm to filter these nodes:
*user:anonymous AND type:node -child*
*Polygons*: Big water bodies, residential areas, parks. This is good data
to merge. The josm filter is:
*user:anonymous type:way -highway=* -railway=* -untagged**
*Ways*: A lot of main and residential roads have been traced from the yahoo
imagery. I could notice slight alignment issues with the bing imagery.
Apart from road shapes, there is no extra information, very few name tags.
I think its best not to import these unless the existing data has nothing.
Merging these will be painful.
I can create seperate osm files with only that data which is useful to
merge. This will make it easier to merge on a city to city basis.
