Contributing to Mapillary with the Gopro MAX, helmet mount experience. | If the lens covers are not replaceable, it’d get me to consider a cover for the lens covers such as maybe a waterproof housing hoping it minimizes any chance of pickup or distortion. If the (cover over the) lens is plastic, Novus makes a 3 stage plastic polish that would be my go to choice to help minimize visibility of the issue. Using it will grind down very bad scratches but causes smaller scratches, then grind down the smaller ones until you have a relatively clear surface again; all smooth surfaces aren’t technically smooth but look the part when you get close enough. I wouldn’t skimp and use paper towels and such as substitutes in place of their proper polishing cloths (or equivalent) as the average ‘paper’ cloths often start adding their own scratches if enough force is used for Novus to do its work. Before Novus, I used Future Floorwax to make a bad scratch in a multimeter face almost disappear and my sister has had good luck with chap stick rubbed into a cleaned CD/DVD scratch making discs readable again though photography grade optic repairs were not a goal there. If not satisfied with Novus final results, I’d likely consider ‘Fritz glass and acrylic cleaner’ as another option to Novus 1 as it also leaves a thin surface residue (=final scratch filler); not sure which would fill faster. Thanks for the OsmAnd bug report; I observed disappearing view of a live recorded track but don’t think it has been limited to when start is shown on screen. I have found it intermittent and had got it back to working when the start was many screens away but do not recall actions I tried to deal with it. Seems like showing tracks now makes screen scrolling annoyingly laggy but maybe it did that before as I haven’t done much with it. OsmAnd~ 4.3.8 from fdroid here also with no ‘Live updates’ map downloads at present. Thank you for sharing your experience. I’ve considered a 360 cam for this but between resolution limits, battery runtime, mounting, and general workflow, I haven’t brought myself to get one and had a basic action cam or cell phone camera as intended plans instead. Hope my ideas are wrong and it works out as a great experience. |

Running JOSM on X86 without Oracle's JAVA | Another solution is adoptopenjdk that seems to represent itself as a more prominent flow for future java releases and such. |

Hello World | Welcome! There’s a lot to learn because there is a lot you could map but you don’t have to learn how to map it all to get started. Don’t feel intimidated to make that first edit and ask if you have any questions. |

Resurrecting Meet Your Mappers | Nice tool. Somewhat misleading to rank users based on that area alone; leads to ‘new mapper’ title with 1 edit labeled for a user from 2016 with over 4k edits; just need to understand that its entirely based on the selected region and not the user as a whole. |

Easily map individual parking spaces using the terracer plugin in JOSM | Though you can do that, if spaces are evenly divided, the example above requires drawing 12 less lines and does not require all the split operations as gridify does all that work for you. When I do longer or curved parking and notice distortions then I will manually break it up into smaller chunks (=occasional use of step 4+6 but on groups of spaces) then apply gridify to each chunk. This also works with angled spots where cars enter only in one direction. I also sometimes ignore the current ‘paint’ and divide the area as its likely intended figuring after a while it all gets repainted/paved and the next try will likely be better; areas for that are usually bordered by curbs. If it seems less bounded then I may copy the paint as is now. To deal with the missing spaces on the ends I usually map as if they were there so other spaces line up right and delete the fakes after to get more consistent dimensions on the spaces. Adding the single end spaces later would also work but seems like more work to add a 4+ node area after then to delete an area. I will usually add lines/nodes temporarily if helps with alignment then delete when done if they weren’t a further part of the object. One example area I worked on (and need to do a lot more) with angled spaces is osm.org/#map=19/33.64353/-112.22515 but I can find others again if desired. |

Quick update on Maxar imagery | Lost the higher resolution (at least in my area) digitalglobe premium then this was a major saddening moment. Still patiently looking forward to the return though glad you guys fight the bad actors. Any chance work has progressed in trying to get a way we can find approximate imagery age too? Newer lowres + older hires imagery combinations are helpful for mapping. Always wondered if it was possible to get imagery for my handheld garmin gps I use for my on the go osm notes at the moment but gotta say that lazyness kicks in for me as I usually doubt the effort would be justified. Thanks again! |

“JOSM and Java” on German forum | Me using JOSM for hobby meets the licensing. Whether or not my edits are “work”(=difficulty+nonfun rating of the edit), I am not any kind of an employee for anyone doing said edits, nor would any volunteer editor. Mapbox/Telenav/etc. employee at work modifying OSM with JOSM is where the question comes into play. They are at work performing their job and java is needed to do so (sticking to running JOSM in this case obviously); that’s a business use even if their job is modifying a nonprofit’s dataset, whether or not they were to profit from said dataset. I’ve had issues with openjdk8 on FreeBSD for JOSM with Mapillary and Microsoft streetside plugins where research of errors said to upgrade to java11; will do once FreeBSD community gets their ports tree better supporting newer jdk versions as dependencies properly (haven’t looked lately). On Windows the issue I recall was no support to load the autoupdating weblauncher files and had to download/run a single release. Though it would be easy to use chocolatey to also download wget/aria2c/etc. program and make a batch file to download then run josm each time, it is also easy to use chocolatey to download josm, which chocolatey may end up days behind main release of each program but can keep openjdk and josm relatively up to date. josm chocolatey maintainer also seems fast to respond though the only issue I had was an install failed because he points to josm versioned releases and a recent but slightly older release file which had the version in the name was removed from josm servers when the new version came out. Anyone have updates otherwise though for adoptopenjdk efforts? Felt weird not having a webstart type feature in the Windows copy of openjdk. |

Easily map individual parking spaces using the terracer plugin in JOSM | oops, meant to comment here instead of at the source so pasting here too… A plugin called gridify can help make slightly shorter work of that; draw a box (I use building tool), check/change tags, use gridify to split in # of rows ‘and’ columns. I then select the spaces and the general parking area and add both (should I just do spaces only?) to a relation of type=site and site=parking. Seems to work nicely on the slanted parking slots too though you need to start from a paralellogram even if you sloppily make a box and add a couple nodes then delete the excess from the corners or grab 2 of the nodes on one side and slide them to get your slant. |

Updates to DigitalGlobe imagery layers | My understanding was that DigitalGlobe standard was lower resolution while Premium being newer, higher resolution including some nonsatellite sources, and better image postprocessing. Was that correct and will that continue or will the two Maxar choices have different meanings? Will there be a way to get an approximate date of the imagery? In Phoenix, AZ I have always had good results of clear imagery without any major skewing of alignment. DigitalGlobe Premium looked to be aerial clarity though often without any steep angles and at a decent time of day for shadows to help see objects heights without often hiding anything. Though new is often great to have, higher resolution, seasonal variations, and differences in time of day and even slight angles from imagery have been necessary to make some of my edits possible. I can start to watch more for strange distortions from Maxar images in areas I work but if even the premium will be significantly lower resolution than Mapbox (=basically the old DigitalGlobe Premium with slightly different final processing) and Bing while having worse offset out of the box compared to DigitalGlobe and Mapbox aerials that i have known offsets for will make it not be my default go to for editing. Whatever the goals and outcome, thanks for being another usable source for us. |
