3D map of the Czech Republic, made from 12.5cm/px imagery (2017)
- aaronharnly 4y agoVery cool map, but wow that is a lot of advertising cookies to individually choose!
- ssl232 4y agoDidn't see any, which I assume is due to my use of the Easylist Annoyances list in uBO. In my experience it blocks most cookie popups.
- Toutouxc 4y ago3D map of my home country made available by our local map provider Mapy.cz (those guys rock). Some more info: https://www.melowntech.com/post/2017/08/11/mapycz-country-wide-3D-model.html https://www.melowntech.com/post/2017/08/11/mapycz-country-wi...
- gus_massa 4y agoNice! (Note: It takes forever to load, but it's worth the wait.) The not yet loaded tiles give a interesting "thirteen floor" effect :) I found a glitch https://imgur.com/a/6Oh3AQn https://imgur.com/a/6Oh3AQn https://en.mapy.cz/zakladni?m3d=1&height=1100&yaw=234&pitch=-18&l=0&x=13.7045910&y=50.5620148&z=16&base=ophoto https://en.mapy.cz/zakladni?m3d=1&height=1100&yaw=234&pitch=... It looks like a quarry. Is the wall too vertical just in the border between tiles? Did they dug that part just between photos?
- yreg 4y agoMapy.cz are very good outside of Czech Republic as well.
- Jamie9912 4y agoI was wondering why it kept working as I passed the German border
- inglor_cz 4y agoI prefer them to Google Maps. I even like the look better.
- sorenjan 4y agoThey're probably my favorite OSM map style, especially the outdoor variant.
- Daniel_sk 4y agoPerfect for offline hiking maps in Slovakia. Google Maps are basically unusable outside of car roads.
- andrewshadura 4y agoNot for offline (unless you pre-cache), but https://Freemap.sk https://Freemap.sk (which is also OSM-based) is even better for online use.
- yfbvbv 4y agoThanks, the Strava heatmaps look very helpful for finding common off-trail routes in the mountains.
- c7DJTLrn 4y agoVery nice. Now I can look at Prague and think about how much I miss it :) went in April and had such a great time.
- dvh 4y agoAnd the practical application of data like these: https://prehrada.hrach.eu/en.html https://prehrada.hrach.eu/en.html
- sorenjan 4y agoThis looks very useful and would bring electricity prices way down. The best time to start building would have been years ago, the second best is today!
- yojo 4y agoI assume you’re joking, but in case you’re not - the plan would put the capital city (Prague/Praha) under 200m of water.
- kfajdsl 4y agoWouldn't this put Prague underwater?
- UltraViolence 4y agoAwesome. Breathtaking. But the imagery isn't from satellite data, is it? Must be from airplanes.
- lucgommans 4y agoIndeed, something like 25cm or better is typically shot from airplanes. I don't remember what the physical limit is for image quality given a reasonably sized spy satellite (iirc it's around the 20cm mark), but commercially at least, the high quality imagery is all airplanes. Governments often commission such planes to fly ~yearly at something like 10 cm, as well as commissioning height maps[1], but the very good stuff is not released to the public for privacy reasons. I think the best I've ever seen is 15cm. The point clouds from those height maps alone, though, I already find to be quite interesting/revealing. You can see the contours of e.g. a tree exactly, even without having any imagery laid onto them: https://snipboard.io/tPsRBo.jpg https://snipboard.io/tPsRBo.jpg [1] For those that can read Dutch, how the Actueel Hoogtebestand Nederland is made: https://www.ahn.nl/ahn-the-making-of https://www.ahn.nl/ahn-the-making-of

- isoprophlex 4y agoDoesn't PDOK provide 8 cm resolution photos of The Netherlands?
- lucgommans 4y agoRecently at an OSM meetup with the local government in Aachen (Germany), they mentioned that some imagery they shot was deemed too invasive and only used internally. I thought that was 10cm, but now checking what is available, looks like I was wrong! Probably it was 5-7cm then? Or maybe this was rather about the imagery available from different angles, so you can see into gardens from different directions? In iD I see that indeed the PDOK imagery is now labeled 7.5cm, but checking that against the Belgian and German 10cm: PDOK 7.5cm: https://snipboard.io/fbWqYM.jpg https://snipboard.io/fbWqYM.jpg AIV Flanders 10cm: https://snipboard.io/Ahn4lJ.jpg https://snipboard.io/Ahn4lJ.jpg NRW (Germany) 10cm: https://snipboard.io/RpT3vA.jpg https://snipboard.io/RpT3vA.jpg PDOK's looks awful, much worse than 10. Maybe some regions are available in a higher resolution?
- lucgommans 4y agoImpression for those that don't want to wait for the application to load: https://lucgommans.nl/tmp/prague3d.html https://lucgommans.nl/tmp/prague3d.html (5MB, 10s mp4 of a square in Prague) A bit choppy because of the basically nonexistent GPU, and I just made it with xdotool (moving the mouse straight/consistently) while recording the screen, but I'm quite impressed with the level of detail of this 3d map!
- photochemsyn 4y agoWhy don't map sites ever publish 3D as topo lines overlaid on a flat 2D map? It's computationally much cheaper, and it's not too hard to learn to read a topo map, as long as the elevations are printed in a reasonably dense manner.
- jeffalyanak 4y agoWhy sacrifice accessibility and usability to save on a bit of computation?
- jeffalyanak 4y agoDon't get me wrong, I think it would be super cool to _also_ include a topographical map feature for those who wanted/needed it, but I don't expect most people would be able to use it in lieu of a simple, visual 3D view.
- asutekku 4y agoBecause for a layperson, an actual 3D map is much easier (and prettier) to read than a topo line map.
- torstenvl 4y agoLiterally none of these are "actual 3D maps," they are topo maps. The only additional information they provide is the 3D extension of objects that were already discoverable in 2D. "Can this map help me find the town hall of Whittier, Alaska?" If not, it isn't a 3D map.
- infinityio 4y ago> Can this map help me find the town hall of Whittier, Alaska? For those who (like me) who didn't get the reference and were curious about this - the town appears to be mainly consolidated into a single 14-story building [0] [0] https://en.wikipedia.org/wiki/Begich_Towers https://en.wikipedia.org/wiki/Begich_Towers

- zokier 4y agoAnyone with MSFS, how does its terrain compare? Both are based on conceptually similar tech?
- ponyous 4y agoDidn't play for some time but pretty similar. MSFS spawns individual meshes for trees/buildings when you get closer so still a bit better imo, but keep in mind in game you are always pretty high so they didn't focus on first person view details.
- dividuum 4y agoThe raw terrain texture and height data is probably a bit lower res in most cases. Some places have photogrammetry, in which case it looks pretty good and looks similar. Outside those areas, which is limited to mostly major cities, any structure you see is auto-generated using some AI algorithm. It looks at the satellite images, open street map metadata and more and guesses what kind of structure matches best. Cities generated that way look ok, unless you fly too close :)
- ralusek 4y agoThis is a very pleasant 3d space to navigate on mobile. I was intuitively able to pan, zoom, rotate about the vertical axis as well as tilt. Put two fingers on the screen and move them vertically to tilt, move them tangent to the original contact center point of the place between two fingers to rotate, pinch them to zoom.
- cycrutchfield 4y agoIt’s missing Královec
- smcl 4y agoFor the non-Czechs: this is a running joke about Kaliningrad electing to be annexed by Czech Republic after the occupied territories in Ukraine "voted" to join Russia. There were a bunch of memes and tweets going around, adverts for holidaying by the Czech seaside, or joining the new Czech Navy to serve aboard the aircraft carrier "Karel Gott". A few companies played along, it was actually pretty funny :)
- folli 4y agoVery nice! Obligatory and shameless self promotion everytime the topic of 3D maps comes up: I recently created a web app to visualize GPS tracking files in a 3D terrain. You can upload your GPX or FIT files and it generates the 3D Terrain using Babylon.js It's called https://cubetrek.com https://cubetrek.com
- reaperducer 4y agoI recently created a web app to visualize GPS tracking files Off topic, but since you work with GPS tracking files, perhaps you can recommend a GPS tracking device for me. Until last year, I used one I got around 2005 that was about half the size of a pack of cigarettes. You turned it on, and it would start logging waypoints at 10 minute intervals to a standard text tracking file on a microSD card. I could unload that text file into my computer and plot the route on a map in a bunch of mapping applications. It was great because when I was going on an adventure off the grid, or traveling overseas or something, I'd clip it to my backpack and then when I got home look at all the fun places I'd been. I recently tried to find a replacement on Amazon, and nothing is suitable. They are all: - Built with a big magnet for clamping to the underside a car - Just a stripped-down Android phone, so large, fragile, and complicated - Require a subscription - Require cellular connectivity - A watch - A piece of software I don't want connected. I don't want to subscribe to anything. I don't want it to drain my phone's battery. I don't want to stalk my ex-girlfriend. I just want something simple that I can turn on and turn off. I know it's possible, because I had one. I just want to find another one.
- baggsie 4y agoGarmin Etrex.
- reaperducer 4y agoDiscontinued, according to https://www.garmin.com/en-US/p/6403 https://www.garmin.com/en-US/p/6403 The only available Garmin alternative is $200. The one I'm replacing was $30. But I'm willing to go to $75. Also, it's a bit large because it has a screen, but that's not a deal-breaker. The one I'm replacing didn't even have a screen, just a light for power and a light to indicate it was connected to the satellites.
- yread 4y agomy only gripe with mapy.cz is that it's difficult to figure out the altitude of a place. You have to count the contour lines which can get tricky. Id love m seeing it (next to wgs84) when i long tap a location on a map

- 101008 4y agoAwesome - since I was a kid I always dreamt with something like this but for the cities I know, because I thought that would make it easy for videogames to use them to set stories. Playing GTA (or other videogames) on my own city would be an incredible experience.
- TDiblik 4y agoI like to use mapy.cz when looking at czech republic, because they're veeery recent. Only problem I have with them, is that they are intentionally uncompatible with leaflet. They have their own api/map library and for some reason prohibit usage with other map libraries, because (as per their docs, api.mapy.cz) they believe that accessing their maps directlly is some kind of abuse? Other than that, it's a good product.
- ChrisMarshallNY 4y agoThat's cool! However, this road looks like it might give a rough ride: https://en.mapy.cz/zakladni?m3d=1&height=138&yaw=234&pitch=-23&l=0&x=13.7509428&y=50.5238407&z=20&base=ophoto https://en.mapy.cz/zakladni?m3d=1&height=138&yaw=234&pitch=-...
- TheRealPomax 4y agoMight be cool, won't know, because of that full page "we are tracking you, do you consent, or do you want to go through a click adventure that'll probably take half an hour before we pretend that analytics and tracking cookies are essential site functionality and we refuse to give you the option to turn those off" notice. If you can't write your site code to do the right thing when DNT is turned on and without needing sessions to serve restful data, your site isn't done, and your code has bugs that need fixing.

- adenozine 4y agoOr just don’t use it? These sorts of comments always ignore the bidirectional relationship between websites and web users. They don’t owe you anything, you’re just another customer with a choice to make.
- TheRealPomax 4y agoYes, that's implicit to the complaint: "too much tracking and profiling being requested: won't use." And then you post a comment letting others know, in the hopes that they do better on their own websites because they see people voice the fact that they'll bounce on unreasonable tracking modals. They don't owe me anything, I don't owe them anything, and when someone with whom we have no debt relationship one way or the other goes "give me your personal data or I won't show you anything, not even a preview to justify handing over your data" should be called out as making an unreasonable request before, as you suggest, moving on.
- adenozine 4y agoI suppose I could understand this complaint more if this was an unusual sight to behold, but surely you see this pattern a million times a day like the rest of society? I guess it just seems like it's a little overly pedantic, like those people that insist every intersection be replaced with a roundabout because it's more efficient for traffic. It misses the point. I think the law requiring websites to show the stupid things at every turn was a bad one. It should have been required of browsers to come up with some kind of one-time-per-user configuration standard of data collection and just be done with it. To me, that's better to do it once or twice per computer or whatever the case is, than with every little single-purpose website that someone browses to. Anyhow, I misread your original complaint anyways, I should've read more carefully before typing. That's my mistake.

- wwilim 4y agoIt also has a route planner which can plan a walk around a given spot that takes roughly the specified time or is roughly the specified distance
- BonitaPersona 4y agoI remember back in 2010 when I did my ERASMUS stay in Prague, and mapy.cz and their startpage (can't remember the URL or name) was leagues ahead of anything I had seen up until them. Way ahead of Google. And, at the same time, the interface was straightforward, clear and concise. It felt effortless, in no insecure need to "feel cool". Its only preoccupation was being extremely useful in the most honest way. I felt enamoured with it. And it even had great naps for my own country, which isn't exactly close by.
