Transportation Tracks

October 8, 2017

Since acquiring an improved GPS, I have been surveying highways, train routes, bike paths and hiking trails, merely by carrying the GPS while driving, riding or walking the route. The GPS is set to take a latitude and longitude reading at intervals of 0.1 mile for highways and 0.02 mile for trails, which is adequate for most mapping applications. For more recent surveys, intervals of 0.02 miles are used in all cases. Some bike and hiking paths were surveyed manually, with appropriately spaced waypoints. In some cases, additional points were inserted into highway tracks near tight curves.

On each trip, I recorded points of interest, particularly the beginning and end of the route and stations (for railroads) or interchanges (for highways), as waypoints. These are embedded into the tracks at the proper locations with suitable comments.

Latitude and longitude are given to the nearest 0.000001 degree, which is less than one foot, but the measurements were obviously not that accurate. Since freeway interchanges can be rather large, the coordinates of interchanges are even less accurate.

After much processing, the results were packed into simple database tables in .DBF (dBase) format. Tables in this format can be imported into most database applications. The fields are as follows:

     name       type       width   decimal  description
     ---------  ---------  ------  -------  -----------------------------------------
     SERIAL     Numeric    3 or 4     0     record number (1 is first)
     LATITUDE   Numeric     11        6     latitude in degrees (north is positive)
     LONGITUDE  Numeric     11        6     longitude in degrees (east is positive)
     ELEVATION  Numeric      5        0     elevation in feet
     DISTANCE   Numeric      6        2     distance in miles from beginning of track
     COMMENT    Character   64              comment for embedded waypoint

Generally, each table is in south-to-north or west-to-east order, even if the route was driven or ridden in the opposite direction. There are two exceptions.One exception is California Highway 54, whose eastbound and westbound lanes between I-5 and I-805 are separated by the Sweetwater River. The westbound lanes in this area were surveyed separately. However, the points are listed in west-to-east order even in this case. Highway I-8 has some widely separated eastbound and westbound lanes in the mountains, so the westbound lanes are listed separately east of E. Willows Rd. A table for a hiking trail generally starts at the trailhead.

County highways are incompletely signed in some places. They often bear several street names, and it is not always clear where the names change. In some cases, it is not even clear where a county highway begins or ends.

California Highway 188 was surveyed in both directions, and then the points were merged.

Points listed as "US-MEXICO BORDER" are actually some distance north of the border.

Tracks are available for the following routes:

\ The term "hiking trails" includes equestrian and mountain biking trails and dirt roads that are not open to motor vehicle use (except for emergency and maintenance vehicles).
