I've been looking at some of the recent changes to rendering of T@H, and<br>
have some comments.<br>
<br>
Looking at the US at zoom 4 shows 3 distinctly rendered zones:<br>
East, Southwest, and Northwest. Looking a bit closer, it seems like the<br>
east is further subdivided into northeast and southeast.<br>
<br>
Of these, it seems that the southwest is the oldest (zoom 8 tiles last<br>
rendered in January), then the northwest and southeast (zoom 8 tiles<br>
rendered in early March), and finally the east (zoom 8 tiles rendered in<br>
the last week or so.<br>
<br>
I have the following observations:<br>
<br>
1. rail is overemphasized in the oldest zone, but completely absent in<br>
the newer ones. This is unfortunate.<br>

2. State borders are missing or absent in all but the oldest.<br>
</blockquote><div><br>I think state borders are there, they are just drowned out by secondary roads.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
3. secondary roads are overemphasized in the newest zone. It makes<br>
whole areas into orange blobs.<br>

They were about right in the middle-aged one.<br>
</blockquote><div><br>Agree, although someone commented recently that many secondary roads imported by TIGER should more realistically be tagged as tertiary.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
4. primary roads are underemphasized in the middle-aged zones, but about<br>
right in the newest zone.<br>
</blockquote><div><br>Agreed.<br><br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br>
What do others think?<br>
