What's New in White Mtn Hiker NE
4.1.0
May 11, 2026
v. 4.1.0 -- 11 May 2026 • IMPROVED -- Trail accuracy has been further improved using planimetric NAIP 1 m resolution images above treeline. The accuracy of the new segment of the Ammonoosuc Ravine Trail has been improved. • IMPROVED -- Formatting in the time table has been improved. • FIXED -- A visual glitch in light mode in the Calculate Pace screen has been fixed. v. 4.0.0 -- 17 January 2026 • All major trails, where possible, have been located to within 1-2 m accuracy using texture shaded 1 m resolution LiDAR data and 1 m satellite imagery. I estimate that about 60% of the trail length for well used trails has been relocated to that resolution. The original source of digitized trails has been change from USFS to Open Street Map as I have verified that the latter, in general, have 5-10 m accuracy whereas the USFS digitized trails have lesser accuracy and in a several cases are off by 50 m or more. You can see my report on trail accuracy in the White Mountains at: https://www.rickallmendinger.net/reports. • You can now show trail names directly on the map at zoom levels 13 and higher. Trail names are turned on by default but you can turn them off in Settings. • You can now generate hiking time tables for individual trails as well as custom hikes. Time tables for individual trals will show time and distance to the intersections with all other trails, to huts and shelters and to all summits within 30 m of the trail. You can now reverse direction for any time table generated by the app. Don't forget that you can also export a text file of a more detailed time table to share with hiking friends or reading into a spreadsheet. • The core of the area -- the Presidential Range east to the ME-NH border -- is now available with rendered LiDAR topography to zoom level 17 (about 1.2 m/pixel). Elsewhere in the region the zoom level is limited to 16 (about 2.4 m/pixel).
