When there are more than n (currently 1024) results in an area, it shows only
the first n results. You can choose which n these are (random sample, most
recently updated...). This is a non-authoritative view.<br>
<br>
Once the view is zoomed in far enough to show all results in an area, it shows
an authoritative view.<br>
<br>
Non authoritative views are shown with circles, authoritative views show the
actual OS Locator bounding boxes. This is partly to do with making a clear and
obvious distinction between views where you're seeing everything and views
where there are some thing you're not seeing . It's also to do with the way the
two different types of geometry behave at different scales. If I showed the
boxes at low zoomlevels, they would just end up being tiny subpixel dots.<br>

<br>
Yeah that annoys me too.<br>
<br>
I tend to do the shift-drag-box more though.<br>
<br>
Previously you weren't able to select non-authoritative points at all, but last
night I changed it so that you can make selections that appear to be persistent
across the authoritative-non-authoritative boundary, as I found it stupid that
you couldn't see details of a match without first zooming right the way in and
possibly losing track of which result you were interested in.<br>
<br>
It would be nice if I could maybe hijack the doubleclick event and pass it to
the map. I'll have to think about this.<br>
<br>
> Are there any differences between what you've done & ITO?<br>
<br>
My algorithm does fuzzy matching to find streets with smallish errors and AFAIK
theirs doesn't.<br>
<br>
I keep a history of match state change events, which will probably be useful
for some fun features in the future.<br>
<br>
Theirs supports not:name=, I haven't got round to that yet (I'm slightly more
interested in being able to tag the actual OSL entry as being incorrect).<br>
<br>
They've got tiles which are very good for use in-editor. Mine, you've still got
to pan around in a separate window.<br>

(the first thing I've got to do though is fix a really stupid replication bug
of mine)<br>
