If you find an issue with the data in Northwest Topos, please post about it here so I can correct it!

I don't know if this is an error, or expected behavior, but with City Navigator on the 60csx I don't see the Topo data.  If I turn off the CN on the unit, it shows up.

In version 0.3 at about 47 20.036  122 01.425 is listed "Washington Air Museum".  One, it's in the middle of the woods east of Lake Sawyer between a couple of trails.  Two, I can't find any such museum listed in Washington (which may be more my poor search skills...).

Glad to see that the forums are working; they'd been so quiet lately that I was starting to wonder! Smiley

That POI came from the Bureau of Transportation Statistics.  Here is a web site that describes this landing pad: http://www.city-data.com/airports/Washington-Air-Museum-Heliport-Black-Diamond-Washington.html.

Obviously this information is wrong, but so far I haven't tracked down what the location should be (if it exists at all).

Well, that listing is about 23 1/2 years old - there are only small trees and shrubs in the area - yea, it could have existed back then.  Maybe plans changed and the area has reverted to normal.

On-the-ground recon trumps the "official" data!  I'll pull the waypoint from the database.

The Ken Blais discussed in this article is the listed owner of that apparently defunct or incorrectly-located museum/heliport. Kind of interesting:

some roads on south side of Grand Ridge, Issaquah are coming as almost white (not showing the outside lines). do, it looks like they are not there.

.

trying this for first time. so, may not get the attached 'mark-up' image.

Hi Jon - Looks like you picked up some old trails from previous editions:

Shadow of the Sentinels Trail 623
Baker River Trail
Monte Cristo Trail
Weden Creek (Gothic Basin) Trail 724 (the northern part of the trail is wrong - there's a discontinuity at about N47 59.996 W121 26.459; the part south of there is right)

NW Trails 1.55 has the right versions.

Rockport State Park:
A trail is indicated as ending at about N48 29.446 W121 37.184. According to my track log, that's where it joins the road.

Forest Road Nf-37 needs to be moved a bit to the WNW in the vicinity of the Skyline Divide Trail. Right now, the trail crosses the road, instead of starting from it. Based on looking at GPSVisualizer's rendering, the trail's in the right place.

Not so much an error as a suggestion: the pedestrian/bike bridge on the Old Cascade Highway at N47 43.552 W121 08.549 should be specified as a pedestrian/bike-only bridge.

There's been no regression; rather Northwest Topos is not yet up-to-date with the current trail data.  It won't be until it's out of beta, which I am defining as completely revamped with updated contours and trail data matching the current release of Northwest Trails.

I've adjusted it so it meets the road now, but that is not matching your coordinates.  Unfortunately, the aerials of the area are of no use (no visibility through the tree canopy) so I can't verify where things should lie.  I need more data! Smiley

This was a case where the GIS road data wasn't a good match with reality.  I've edited it to match the aerials.

I'll add this info to the POI.

Thanks a ton!

My pleasure, Jon. I guess I figured you'd picked up old trails since part of the Weden Creek/Gothic Basin Trail is new.

Looks like I'll have to get up to Rockport again and take a quick turn around the old camping area.

Spotted a discrepency I believe...

At N46 48.860 W119 54.790 there is a label that indicates Skagit Wildlife Refuge. Skagit is a bit NW of that location. It should probably be BLM Land.

Good catch!  No idea how that might have happened; probably had multiple polys selected when applying a name to the proper one.

Hi Jon - There's a POI for the summit of Mt. St. Helens at 6818. It's apparently something around 8363, though the USGS topo has it at 8333.

I've corrected this and you'll see the change in the next release.
