| Stillgelegte Bahnstrecke Elze–Löhne bei Fischbeck (Weser) – Episode 3 | I have not used JOSM very much. But on your jpeg it gives the angle of the way. If you noted the angle of the rail line you only have to add or subtract 90 degrees. I like you low tech solution of a set square on the screen. I was thinking of laying a sheet of paper over the screen and tracing map with a different coloured felt pens to create a simple walking map. Happy Mapping |

| Meandering streams | I noticed a few ago that a parish boundary followed the route of boggy bit in the field that I remembered from 1952 .and realised the river line had probably been moved when they had constructed the lock. It is easier was easier to build the lock on dry land then divert the water through it. I noticed similar situation when the A14 road Cambs UK 2015 2021 was built. New bridges across the new A14 were built adjacent to the old roads together with the linking roads and over night the road was sent over the new bridge causing little or no delay. This old Roman road was once straight but now kinks a little. see osm.org/?mlat=52.2923&mlon=-0.1490#map=15/52.2923/-0.1490 I have mapped a lot of footpaths in the last almost ten years. When I walk the path again I’ll re-check against my GPX and Bing and maybe edit them. I can inspect the date of the mapping to see when if and when I edited before. I use the Potlatch editor to do this. I’m don’t know if older Satellite or Ariel are available. You could ask in the Help Forum. Happy Mapping Andy |

| Survey discovered gas leak. | Thanks Jedrzej , Yes we can, we can also see other interesting things, such at buildings, old and new, farm machinery, different crops and wildlife. .We can talk to other walkers get fresh air, vitamin D and exercise. Win win win win! |
|
| Survey discovered gas leak. | Thanks Bernard, I remember seeing an asphalt path and kerb that had been lifted locally by water burst, damage was quite surprising . Gas explosion/fire I don’t want to see. |

| How to map partially overgrown building? | I posted a question that points to your interesting question. see https://help.openstreetmap.org/questions/82606/mapping-under-ground-or-earth-covered-building |

| Aerial imagery offset comparison (Harford County, MD USA) | Using all available GPX traces, in an editor, will allow us to check and adjust imagery. Several traces will give a fairly accurate result. Even if an area is on OSM it may be useful to upload GPX data because the area has been mapped by a mapper who has been fooled by misaligned imagery, you see it and you believe your own eyes :-) so upload those traces. If your device seemingly off sets your position a similar amount on the map several times, that bit of map may have been created from off line imagery. Happy mapping |

| Most cellphone GPS traces will pollute OSM | I have seen a few very poor quality traces, it is good idea to inspect them before uploading to OSM. GPS Prune is a good open source ( no ads and free) tiny, java based PC app that will display a GPX over OSM . You can then decide if it will add anything useful to OSM. It also makes it easy to trim, or prune, any rouge points or private info in the trace. The time of each point can be geolocated and matched to a sound recording or a Jpeg, just set the time on the camera first ideally, although it is possible to adjust and correct afterwards. see https://activityworkshop.net/software/gpsprune/ |

| Come usare la cartografia IGM come layer imagery in iD | I like the map style and i think maps with a white backgound are the best, It is similar style to GB Ordinance Survey maps and the USSR military maps. I think the military realised the importance of clear maps that can be read in poor light conditions White backgrounds are easier to read and also use less ink to print. I regret that most of the OSM map renderings have too much filled in with colour which reduces clarity, perhaps when my eyes young it was less of a problem. BUT unless the licence suits OSM terms We cannot use it. |

| Amusement park modifications | My Aunt and Cousins lived in Northumberland road on the edge of the park when i was ten years old … 1957 .. Heaven! I have added edited a bit in the area after walking it the area either alone or with Kettering Ramblers ( HI all ). Northamptonshire and the Nene have some great footpaths. I was concerned for Wickstead Park when i ran short of income due to covid. Visit it it’s great. |

| My OSM User Journey | You are correct it is mainly for mappers, that is editors of the map. It works for me. Sharing a link with a marker works for me, using a Win 10 or Linux desktops PCs I would not want to edit on a phone or tablet much other than just nodes. |

| Addons für garmin etrex 30 | I like the etrex 30 it lasts well on batteries, i use LIDL Tronic ones. I trimmed down a phone screen protector. I also use the ankle section of an old sock sewn into a pouch with a draw cord to either hang from my neck or protect it in a bag or pocket. It also works well wit free map scans using garmin custom maps and osm downloads. |

| 不懂就问 | I use the diaries to learn of others mapping experiences and methods and to share my own. see osm.org/user/andy%20mackey/diary/ |

| Geoglyph of Two Coiled Snakes | Did you map them from an aerial provider if so which one. Or a survey? Way: Small Spiral (826794673) Version #2 Man_made=Geoglyph cleanup Edited 21 days ago by c tito young · Changeset #99481058 |

| Pole Mapping | To be safe and to avoid electrocution use non conductive poles, carbon fiber is conductive, a number of uses of carbon fiber fishing poles have died when getting too close to overhead high voltage cables. |

| Three years with OSM. | Hi John I have been adding footpaths in the Huntingdon Cambs area, since I started mapping almost ten years ago. Some of the paths were recorded on garmin gpses some on and android phones. I enjoy being out often and exploring something new is very good. I do shorter walks and surveys alone but longer ones have been with a few pals or have been on group walks of the many ramblers groups that are based within up to forty or so miles of home. This web site may yield some rights of way https://www.rowmaps.com/kmls/ the other source is to look at the county councils interactive maps of rights of way which from time to time show footpath creations or changes. I like Ordnance Survey maps and usually carry one. If I see a farmer who look about to say “ ask are you lost “ I’ll try and beat him to it and ask “where have i gone wrong? “ they have always been fine in my experience. Th only problem with Ord Survey is that changes to rights of way take some time to be added or moved, often years! to be updated, I have in the past emailed Ord Surv and informed them of changes that Councils have made with landowners to paths. I tell then have look at openstreetmap that’s where they are now. Happy mapping Andy |

| Where's the nearest payphone? | I spend a lot of time rambling, that’s walking in the countryside, recording footpaths and mapping them. I haven’t seen a working red phone box for quite a while. The older ones are so heavy, i believe they have cast iron frames and it isn’t economic to remove them. Often ownership is transferred or sold for a small amount to the village. They then become put and take book exchanges or are used to house a defibrillator and remain a familiar landmark in the village. I have mapped five or six of them. Happy Mapping |

| Unknown Heroes of OpenStreetMap | Yes i agree. How is the song writing coming along ) … no pressure though. Happy Mapping. |

| Viel Spaß noch | i have seen similar edits, Contact them, First be kind to them and complement some of their work before you explain how you mapped the area and that you surveyed the area with GPS and made GPXes and compared them to the aerial, and explain that it isn’t always aligned correctly, send the a link to the wiki about relevant stuff. With luck you may get a good response. Happy Mapping |

| Blurry map on mobile devices | Me again! You may get some feed back from the Q&A forum, i don’t think the diary section is read that much.. Although i enjoy some of the contributors entries. Andy |
