Importing boundaries (admin_level=8) into existing boundaries (admin_level=7) | @Lejun I didn’t find any easy way to disconnect borders effectively. The biggest problem are rivers that are connected with a border for 30 kilometers and hundreds of nodes. The “dumb” and slow way is clicking every node, and then shortcut “g”. You can select the border, click “g” and then it unglues all the nodes. You will have to glue the ending nodes again. It will give you a warning that a lot of nodes are one on top of the other, but I guess if you change the border, that isn’t a problem? But I have a feeling we need a new plugin that can unglue two ways, and move the nodes slightly. Maybe it exists and I didn’t find it. Another tip is finding where a border is connected to a forest or river. I select the forest, and move it a lot (like 50 kilometers). Then it’s obvious where the border stretches across the land. You remember where the connection is, and undo (Ctrl-Z) to return it to the original place, and unglue. When you are done with unglueing, you upload the new state, close the OSM layer, wait for a few minutes for overpass to catch up, and download again. If the forest or river is still there, you have some more unglueing to do (or you didn’t wait enough for overpass to catch up). |

Some thoughts on highway=service vs highway=track | I treat tracks as service roads for farmer and forestry vehicles. Everything else is highway=service or something else. If it goes to a settlement, it’s highway=unclassified + surface=unpaved. The general rule for highways is to map road usage with the highway=* tag, and map the road surface with the surface=* tag. So don’t just put the highway=track tag just because it’s unpaved. That’s what surface=* is for. |

Dealing with incorrect tags in Africa | Highways are just the highest step in road clasification. That tag shouldn’t describe physical properties of a road, that’s the job for specialized tags. |

Starting with OSM Mapping: Mapping my hometown, Jorhat | Great job! Keep it up, and create some competition with the surrounding towns. Is there a rule about languages in India? It would be great if you used the name:as and name:en tags. There are probably people who know only Assamese, and if you use name:en, applications know what label to show the tourists. |

Android OSM apps | OsmAnd for recording gps, audio and photos and looking at offline maps, Vespucci for OSM editing. Some like OSMtracker for recording gps, audio, photos as well as various features from a list of buttons. For addresses there is Keypad-Mapper. |

My first entry. | And before realignmenting roads, know that Bing background might be misaligned. In Potlatch click GPS, and then align the background to GPS traces made by other people. Hold space and drag background. |

Back to mapping thanks to Vespucci | Best field editor ever. There’s so much stuff I would have never mapped without it. Do they have a “donate” button somewhere? |
