OpenStreetMap
Great effort by others of having roads down; Unfortunately most seem to be from sat images, and as a result, are all offset by a rather large amount, and still need to be surveyed.
Never mind that, they were there, close, and Unnamed.
I think I have named almost 300 roads today, and Horsham is finally worth looking at!
Solved heaps of errors and warnings, still plenty left to go through, unfortunately not sure how to solve some of them :(
If someone a bit more experienced can look at some of the warnings/issues in this area would be great!

Looks good Emmertex!
I'm not sure which errors and warnings you're referring to. What tool are you using to see errors?

Great stuff Emmertex, It's terrific to see another mapper actually going out and surveying accurate data. Horsham now looks good enough that the various routable OSM maps should be useful for tourists to travel to or through the city.
I've started to "desk check" your data against other sources (googlemaps whereis etc, etc...) also Bing maps allow you to easily switch from OSM data to commercial mapping data. As well the tool
http://tools.geofabrik.de/mc/ is excellent for spotting missing roads or naming errors.
Just to get you started.....
Is it Selkrik Drive or Selkirk Drive?
Is there an Ashwim Close (and/or Ashwin walk) off Selkirk Drive.
Have Jos and Bradburys Lanes been unnamed or deleted (now car parks??)
I've had a look at the keep right errors for Horsham and it's now not too bad at all.
Most of the errors appear to be from the "tracers" tracing driveways or serviceways etc straight across roads without any connections or tracing in really short driveways leading to nothing (and they may also be misaligned as well - only you could tell). Do you want me to try to fix a few of these things. I've done heaps of error fixing in the Canberra area and it's a good way of killing off a few winter nights.

Using JOSM.
Just minor warnings I don't know why they are there, or what it's complaining about.
The warnings are, Crossed ways (when going over a river/channel). Road is tagged bridge=yes for that seciton.
Way End Node near other highway.
Relation Type is Unknown

nm7s9:
Looks like I made typo's.
Selkirk Drive I just corrected.
Yes there is a Ashwin Walk and Ashwin Close.
As for Jos and Bradbury, I don't know of them. Could you let me know their location and I'll check them out.
Happy for you to help me on the area :)
As for missalignment, the majority of the city is offset, following satellite images is no good for this region, and the offset is not constant either.
I will get to aligning everything once I survey it all.

Between Darlot and Firebrace, just south of the Dimboola Road, Baillie Street Junction (according to Google maps)

nm7s9: On Jos I think there is a sign, but I think 4 entrances to the car park as shown on OSM is wrong as well, there is only 3. I need to survey this one. It is more accurate on OSM than on google.
This also applied to Bradbury Lane, it only enters on one side.
This same innacuracy is seen on the block south again.
Leave all those with me, I will go survey it.

> Crossed ways (when going over a river/channel).
Tagging bridge=yes is not enough. You have to set the layer tag to tell which way is on top of another. layer=0 is implicit set when no layer is given. bridg alone is not enough because you can have bridges over bridges. But bridge=yes and layer=1 suits best in most cases.
Way End Node near other highway.
Maybe it is a short driveway having its end node very near to the street. This will generate a warning like this one. But sometimes it is a not connected street where it should be connected but you missed the cennecting street when clicking.
Relation Type is Unknown
This can be ignored if you aren't working with bus routes or other complicated relations. There are hundreds of relation types in use but Josm only knows a few.
