DJ BonsaiNope, sorry.<a href="https://bildung.social/tags/DXO" class="mention hashtag" rel="nofollow noopener" target="_blank">#DXO</a> <a href="https://bildung.social/tags/PhotoLab8" class="mention hashtag" rel="nofollow noopener" target="_blank">#PhotoLab8</a> kommt mir optisch zwar sehr entgegen und macht aus meinen RAWs sogar bessere Bilder als <a href="https://bildung.social/tags/Lightroom" class="mention hashtag" rel="nofollow noopener" target="_blank">#Lightroom</a>. Auch den Preis hätte ich bezahlt.Aber die hohen Upgrade-Preise, fehlende hauseigene Goodies wie <a href="https://bildung.social/tags/HDR" class="mention hashtag" rel="nofollow noopener" target="_blank">#HDR</a>, Pano, Karten und <a href="https://bildung.social/tags/Geotagging" class="mention hashtag" rel="nofollow noopener" target="_blank">#Geotagging</a> bringen mich halt nicht weiter. Schade ums tolle Denoise und so, aber ich arbeite mich jetzt doch mal durch die etwas irre Lernkurve von <a href="https://photog.social/@darktable" class="u-url mention" rel="nofollow noopener" target="_blank">@darktable</a> . Bis Ende August brauche ich eine LR-Alternative…

Terence Eden’s BlogReverse Geocoding is Hard<a href="https://shkspr.mobi/blog/2025/04/reverse-geocoding-is-hard/" rel="nofollow noopener" translate="no" target="_blank">https://shkspr.mobi/blog/2025/04/reverse-geocoding-is-hard/</a>My wife and I run <a href="https://openbenches.org/" rel="nofollow noopener" target="_blank">OpenBenches</a> - a crowd-sourced database of nearly 40,000 memorial benches. Every bench is geo-tagged with a latitude and longitude. But how do you go from a string of digits to something human readable?How do I turn <code>-33.755780,150.603769</code> into "42 Wallaby Way, Sydney, Australia"?Luckily, that's a (somewhat) solved problem. Services like <a href="https://opencagedata.com/" rel="nofollow noopener" target="_blank">OpenCage</a>, <a href="https://stadiamaps.com/" rel="nofollow noopener" target="_blank">StadiaMaps</a>, <a href="https://nominatim.openstreetmap.org" rel="nofollow noopener" target="_blank">OpenStreetMap</a>, and <a href="https://geocode.earth/" rel="nofollow noopener" target="_blank">Geocode.Earth</a> all provide APIs which transform co-ordinates into addresses. Done! Let's go home.Except… Not everywhere has an address. <a href="https://openbenches.org/bench/35905" rel="nofollow noopener" target="_blank">Some benches are in parks</a>. They typically don't have a street number, but might have an interesting feature nearby to help with location. For example a statue or prominent landmark.And… Not every address is relevant. <a href="https://openbenches.org/bench/26061" rel="nofollow noopener" target="_blank">Some benches are on streets</a>. But we probably don't want to imply that the bench is inside or belongs to a specific nearby house.Let's step back a bit. Why do we want to display a human-readable address?We have two use-cases."As a visitor to the site, I want to:"<ol><li>Read a (rough) textual representation of where the bench is.</li><li>Click on a component of the address to see all benches within that area.</li></ol>The first is easy to explain:The second is harder. Suppose a bench is in Wellington, New Zealand. We want to create a URl like <a href="https://openbenches.org/location/New%20Zealand/Wellington/" rel="nofollow noopener" target="_blank">openbenches.org/location/New Zealand/Wellington/</a>. That way, users can click on the word "Wellington" and find all the benches nearby. A user can also manually edit that URl to increase or decrease precision.Both of these are problems of precision.Let's take a look at <a href="https://nominatim.openstreetmap.org/reverse?lat=51.476845&lon=-0.295296&format=jsonv2" rel="nofollow noopener" target="_blank">how one of the reverse geocoding services</a> deals with transforming <code>51.476845,-0.295296</code> into an address:<blockquote>Royal Botanic Gardens, Kew, Sandycombe Road, Kew, London Borough of Richmond upon Thames, London, Greater London, England, TW9 2EN, United Kingdom</blockquote>That is too much address!Yes, it is technically accurate. But it contains far too much detail for humans, the postcode is irrelevant, and the weird-subdivisions are nothing that a local person would use.Looking at the full API response, we can see:<pre><code>{ "place_id": 258770727, "licence": "Data © OpenStreetMap contributors, ODbL 1.0. http://osm.org/copyright", "name": "Royal Botanic Gardens, Kew", "display_name": "Royal Botanic Gardens, Kew, Elizabeth Cottages, Kew, London Borough of Richmond upon Thames, London, Greater London, England, TW9 3NJ, United Kingdom", "address": { "leisure": "Royal Botanic Gardens, Kew", "road": "Elizabeth Cottages", "suburb": "Kew", "city_district": "London Borough of Richmond upon Thames", "ISO3166-2-lvl8": "GB-RIC", "city": "London", "state_district": "Greater London", "state": "England", "ISO3166-2-lvl4": "GB-ENG", "postcode": "TW9 3NJ", "country": "United Kingdom", "country_code": "gb" }}</code></pre>Aha! Perhaps I can build a better address using just those components!Except… Not every country has states. And not all states are used when giving addresses. Not every location is in a city. Some places have villages, prefectures, municipalities, and hamlets.New York, New York is a valid address, but <a href="https://blog.opencagedata.com/post/99059889253/good-looking-addresses-solving-the-berlin-berlin" rel="nofollow noopener" target="_blank">Berlin, Berlin</a> is not!There's an <a href="https://github.com/OpenCageData/address-formatting" rel="nofollow noopener" target="_blank">address formatter by OpenCage</a> which is pretty sensible about stripping off irrelevant details. But, to go back to my first point, not every map location on OpenBenches is a street address and - even if it is on a street - it probably shouldn't have a house number.Well, there's kind of a solution to that! Most mapping provider have a POI function - we can find nearby things of interest and use them as a location.Here's a <a href="https://openbenches.org/bench/36734" rel="nofollow noopener" target="_blank">bench in Cook County, Illinois, USA</a>. The POI address is:<pre><code>{… "name": "Central Park", "coarse_location": "Des Plaines, IL, USA",…}</code></pre>I assume there's only one Central Park in Des Plaines. Do people know that "Il" is Illinois? Would "Cook County" be useful?On the subject of localisation, not everywhere speaks English. Do I want to display addresses like "原爆の子の像, 広島, 日本"? How about "原爆の子の像, Hiroshima, Japan"?We're an international site, but most benches are in Anglophone countries.Of course, just because something is physically near a POI, that doesn't mean it is logically close to it.Consider a bench situated <a href="https://www.openstreetmap.org/query?lat=50.580682&lon=-3.467831" rel="nofollow noopener" target="_blank">at the edge of this park</a>The nearest POI is "Gay's Creamery" - across the river. Is that what you'd expect? Is there any way to easily say "if a point is inside an amenity* then use that as the address?I don't want the users of our site to have to select from a list of POIs or addresses, this should be as automated as possible.The PlanFor each bench:<ol><li>Use StadiaMaps to get the nearest POI.</li><li>Get the data in English.</li><li>Concatenate the name and coarse location.</li><li>Save the "address".</li><li>Wait for complaints?</li></ol>Thoughts?<a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/geolocation/" target="_blank">#geolocation</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/geotagging/" target="_blank">#geotagging</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/openbenches/" target="_blank">#OpenBenches</a>

Jon SullivanI've just finished geotagging my photos from November and December using <a href="https://mastodon.nz/tags/darktable" class="mention hashtag" rel="nofollow noopener" target="_blank">#darktable</a>. I use the "apply GPX track file" button with tracks from my Garmin GPS, or otherwise the Cyclemeter app on my iPhone, to accurately geolocate my photos. I get much better locations this way. My bigger cameras don't have internal GPS, but I also do this with all my iPhone and Nikon W300 photos. They can otherwise be off by 100 m or so. That difference matters for my nature observations.<a href="https://mastodon.nz/tags/photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#photography</a> <a href="https://mastodon.nz/tags/geotagging" class="mention hashtag" rel="nofollow noopener" target="_blank">#geotagging</a>

Tuomas Väisänen 📼🧟‍♂️I wonder why <a href="https://vis.social/tags/Twitter" class="mention hashtag" rel="nofollow noopener" target="_blank">#Twitter</a> was so popular in <a href="https://vis.social/tags/Turkey" class="mention hashtag" rel="nofollow noopener" target="_blank">#Turkey</a> in 2012-2015 especially in terms of <a href="https://vis.social/tags/geotagging" class="mention hashtag" rel="nofollow noopener" target="_blank">#geotagging</a> posts?We're working on extracting different types of regional <a href="https://vis.social/tags/mobility" class="mention hashtag" rel="nofollow noopener" target="_blank">#mobility</a> from the data, and Turkey is over-represented in the data. The amount is approximately 2–3 times the content from Italy, France, and Spain combined.

JL Johnson :veri_mast:I am looking for a lightweight -preferably <a href="https://vmst.io/tags/opensource" class="mention hashtag" rel="nofollow noopener" target="_blank">#opensource</a>- PC tool for mass <a href="https://vmst.io/tags/geotagging" class="mention hashtag" rel="nofollow noopener" target="_blank">#geotagging</a> photos, maybe other exif updates. I don't use light room anymore. My notes show I used to really be into Microsoft Pro Photo Tools. But that hasn't been updated in 15 years. v2 was released in 2008.

Jon SullivanHere's a friendly reminder of the usefulness of geotagging photos using GPS tracks, even in this age of GPS in cameras and phones.These photos are from a weekend run with my Nikon Coolpix W300, a compact waterproof camera with a GPS. The 1st map is where the camera thought it was. The 2nd map is after geotagging with a continuous GPS track.The difference can be 100 m in some cases. That's important for nature observations. I see the same with my iPhone photos.<a href="https://mastodon.nz/tags/geotagging" class="mention hashtag" rel="nofollow noopener" target="_blank">#geotagging</a> <a href="https://mastodon.nz/tags/photos" class="mention hashtag" rel="nofollow noopener" target="_blank">#photos</a> <a href="https://mastodon.nz/tags/map" class="mention hashtag" rel="nofollow noopener" target="_blank">#map</a>

Jon SullivanA friendly reminder not to blindly trust locations that smart phones add to photos.All these were taken in our house, yet their locations from my iPhone 13 span about 1 km.It's probably because I took photos inside before my phone had figured out where I was. The same easily happens under a forest canopy.This is important when making nature observations for platforms like <a href="https://mastodon.nz/tags/iNaturalist" class="mention hashtag" rel="nofollow noopener" target="_blank">#iNaturalist</a>. I geotag my photos from a GPS track, including my iPhone photos.<a href="https://mastodon.nz/tags/geotagging" class="mention hashtag" rel="nofollow noopener" target="_blank">#geotagging</a> <a href="https://mastodon.nz/tags/SmartPhone" class="mention hashtag" rel="nofollow noopener" target="_blank">#SmartPhone</a> <a href="https://mastodon.nz/tags/photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#photography</a>

Alex WildIf you are interested in *where* I took a particular photograph on my website www.alexanderwild.com, click on “photo details” and you’ll get EXIF data and a little navigable map at the bottom. I have been automatically geotagging my photos since about 2014, and am working through the older ones to add that information. <a href="https://mastodon.online/tags/insects" class="mention hashtag" rel="nofollow noopener" target="_blank">#insects</a> <a href="https://mastodon.online/tags/geotagging" class="mention hashtag" rel="nofollow noopener" target="_blank">#geotagging</a> <a href="https://mastodon.online/tags/exif" class="mention hashtag" rel="nofollow noopener" target="_blank">#exif</a> <a href="https://mastodon.online/tags/smugmug" class="mention hashtag" rel="nofollow noopener" target="_blank">#smugmug</a>
