| Sep 11, 2021 at 20:09 | comment | added | Babel | OK, then please edit the question accordingly to make that clear. | |
| Sep 11, 2021 at 20:03 | comment | added | David Kan | Nope. Once again, I am curious as to why there is no available official worldwide datasets in the resolution of OSM or at least in a generalisation less than 1:1000000. I know it is possible to get data out of OSM but this process is hardly the most effective way if a ready dataset is available, and, once again, the source of data in OSM is not always clear | |
| Sep 11, 2021 at 20:00 | comment | added | Babel | OK, so OSM is still too much generalized?? Don't think even more detailed data makes any sense... By the way: the red line on your updated image is exactly wht OSM offers: openstreetmap.org/way/380082889#map=15/43.1497/42.9229 - so your question is how you get this kind of detailed border out of OSM in a file? | |
| Sep 11, 2021 at 19:53 | comment | added | David Kan | @Babel, yes, exactly, sorry for the misuse of names. What my aim is is to get data in even a lesser generalization (more vertices), but not from OSM. Let's say I would like to have a full downloadable dataset or an API. | |

| Sep 11, 2021 at 19:47 | comment | added | Babel | Ok, so here you have data that you can download in different generalizations (simpifications), see: gislounge.com/generalization-gis - Generalization is not the same as resolution. OpenStreetMap data really has a high degree of details (many vertices), see: openstreetmap.org/way/150816844#map=16/49.4895/6.2918 | |

| Sep 11, 2021 at 19:34 | comment | added | David Kan | Take a look at this page: gisco-services.ec.europa.eu/distribution/v2/countries/… You can select a country and see it on a map. Zoom in then. You will see that the borders on the map are much more complicated. You can also see that the data is provided in different resolutions (e. g 01m,03m,60m etc.). | |
| Sep 11, 2021 at 19:34 | comment | added | Babel | By the way: do we speak about raster or vector data? You need a basemap (background map) or actual data? Sorry, your question is very broad, please revise it (edit) to add more details - otherwise, it risks to be closed. | |
| Sep 11, 2021 at 19:32 | comment | added | Babel | I guess that the precision of your measurement is not high enough that such precise border data would make any sense. I would re-assess the basic concepts of your very research question and accept the fact that a plane flying exactly along a border might not be located 100% correctly on one or the other side of the border. OSM data is precise enough in most cases, I assume. However, I don't understand what you meanr by "limited to 1:1 mio": vector data by definition has no resulution/scale and can be used with any scale. | |
| Sep 11, 2021 at 19:29 | comment | added | David Kan | 1:1million is not 1 meter as far as I understand, sorry, might have confused you in that comment before. This resolution is actuallt quite a simplified version of the actual border I can see on the map. | |
| Sep 11, 2021 at 19:28 | comment | added | David Kan | I am doing an app that needs to convert airspace borders from coordinates published in official aeronautical data to actual polygons. The thing is, more often than not, those coordinates might contain a "along country border" note. So I was wondering if I could get some highres data. | |
| Sep 11, 2021 at 19:26 | comment | added | Babel | So you need a precision of less than 1 meter - worldwide? Seems a quite unrealistic task. Not everywhere in the world borders are delimited to such a precision, undelmited parts of the frontier exist in many areas of the world and neighboring countries might have conflicting datasets. | |
| Sep 11, 2021 at 19:25 | comment | added | Babel | OpenStreetMap contains for some areas also publicly available and open government data (OGD), so some of the data in OpenStreetMap in fact has an "official" source. However, be aware that even "official" borders can change: between Switzerland and Italy, the border in some regions is defined as the ridge of a glacier - and with changing climate, the borders regularly changes, too. So you should definitely state more precisely: 1. what borders you nedd and 2. for what you need it. | |
| Sep 11, 2021 at 19:23 | comment | added | David Kan | I generally need the whole world for a project I am doing. I have stumbled upon Eurostat and NOAA and Worldbank sources, but all are limited to 1:1m | |
