spaghetti and US highway junctions

Написано от ceyockey на 5 февруари 2012 на English.

I exposed a couple of junctions I'd made in Delaware to scrutiny and got "gee, borders on vandalism", "I would revert on sight", "love the detail" and "looks ok, but maybe overly complicated" types of responses. My argument about detail mapping of US highway junctions is that markings on the pavement have the force of law in some states (including Delaware) and, therefore, are valid for interpretation through restriction-type relations. The difficulty comes in the actual junction site and the many way-crossings which result from interpretation of pavement markings as legally-enforceable restrictions. --ceyockey

Clear your cache to bring back map functionality

Написано от ceyockey на 25 ноември 2011 на English.

The problems with the map are related to conflict between new functionality and cached material (maybe ... there's not certainty on the 'why'). See http://lists.openstreetmap.org/pipermail/talk/2011-November/060724.html for the response received on the talk mailing list.

Map work based on newspaper focus points (Delaware, United States)

Написано от ceyockey на 26 ноември 2010 на English.

For the last couple of days, I've been using the daily e-mail updates for the Delaware News-Journal as a guide to where to improve mapping in Delaware. The majority of those mentions which are geolocated are crime-related. Example: osm.org/browse/changeset/6459256 .

Equipment and software

Just bought my first GPS unit today, an eTrex Legend H unit from Best Buy for ~$140. To extract data from the unit, I've started using GPSBabel, a free software package for interconversion between GPS data syntaxes. It was also necessary to download the Garmin USB driver from the Garmin site to enable the unit-PC connection. (correction regarding GPSBabel's status as free software based on input from Paul Johnson ... see comments on this thread).
