This map is where I live, so it will be interesting what the database querying reveals.
Problems encountered with the map I created several small samples of the data and worked with the smallest one most of the time, until I had my auditing procedures working correctly. Using the code snippet provided in Project Details, I changed the k size and created samples called sampleK10.osm, sampleK25.osm, sampleK35.osm and sampleK100.osm. Once I had sampleK100.osm working correctly I progressively moved up in size. The problems I came across are listed below.
