Show HN: Free GeoJSON editor to visualize, download or convert into many formats
- etagenyeti 7y agoWe aim to provide the best GeoJSON editor out there. Feedback is most welcome!
- nobleach 7y agoIn the editor, I do see Shapefile in the dropdown for downloading. It's unavailable however. (Same for WKT and TopoJSON). Are these paid features?
- hacksOfSumit 7y agoThey will come soon. No paid features planned yet but we will see how much effort the tool is for us in the future. For now, most of these formats will be supported for free.
- MarkyC4 7y agoAs someone who has to edit GeoJSON ~monthly, these would be useful for me: - edit polygons (ie: to add more points). It'd be useful to click one of the points to add a point after it (then click the next point to close it) - import (fwiw: my geojson comes from postgres/postgis ST_AsGeoJSON) - save to gist (or some other share feature). I use this one to show maps to non-tech colleagues for signoff.
- reustle 7y agoThis is really slick! It's missing a few key features, like letting me modify some meta details of an object by clicking, or easily deleting an object. I'd also like a way to more easily create a polygon without zooming in really far to put the final point very close to the original point, instead of ending the drawing. I use http://geojson.io http://geojson.io quite frequently to modify geojson data sets, but there are some annoying bugs especially when working with larger data sets. One key feature they have is being able to swap between multiple tile providers, so you can compare where certain features are positioned on different maps. I recently started a new Geo meetup here in Tokyo, https://GeoTokyo.com https://GeoTokyo.com - I'll share at the next event. Thanks
- mstngl 7y agoAnother feature which geojson.io provides over the tool presented here, is the table view which makes editing / formating / adding information to a large set of features simple and accessible. File management (including open local and hosted files) and the availability of different map layers are appreciated features for daily work as well.
- hacksOfSumit 7y agometa data management is definitely on my list - thanks for your feedback
- m-watson 7y agoThis one is really slick, I wonder how it works with larger data sets. I'll check it out later. Geojson.io is a nice one but I second your comment, anything on the larger side it just crashes for me. I end up just using QGIS with a text editor open for the geojson editing. It ends up being a game of trial and error that gets very tedious.
- hacksOfSumit 7y agoGood point. Performance is a problem on these tools and I need to do some work on that front as well. My email is on geoman.io - send me a data set and let me try. I will make improvements here in the next weeks.
- Eviticous 7y agoI've also been using geojson.io for most of my workloads. The large dataset handling definitely leaves something to be desired. One thing that they do offer though is the option to view satellite map data, which doesn't seem to be available here. I'd love to give this a shot, but most of my workloads are really imagery dependent, so geoman doesn't seem to be an option.
- hacksOfSumit 7y agoThanks for the feedback, consider it done (very soon)
- Waterluvian 7y agoI use GeoJSON all the time in mobile robotics. For indoor robotics, we are using our own local coordinate system. This means that we "lie a little bit" about the GeoJSON spec, treating x and y as linear metres in a flat world. tl;dr: I would love if more tools allowed you to hide the map and just ignore the details of the CRS/Projection. I do so much work on and around Null Island as a result. QGIS has been _very_ good at this. But most online tools always assume use cases are WGS84.
- Darkphibre 7y agoOh, absolutely this! I work on game heatmaps (Halo), player path analysis, etc. Having a flat-world coordinate system with a customer-supplied map is critical.
- etagenyeti 7y agoThank you for the feedback, guys... this is awesome!
- mahesh_rm 7y agoI love this. It could have been really great to have this about 10 years ago, when I was looking for a quick way to manually partition cities' neighborhoods through GEOjson polygons.
- idbehold 7y agoWhy do you allow users to draw circles when they aren't actually a proper GeoJSON geometry. It's just a Point geometry with a custom (unit-less) radius property.
- hacksOfSumit 7y agoThe basis for the editor is my open source drawing plugin for leaflet - Leaflet-Geoman. It supports circles because Leaflet supports circles. GeoJSON is just a format to export Leaflet-Layers - so we made Circles work even though it's custom. You're definitely right about the unit-less part. Something I should be fixing.
- RosanaAnaDana 7y agoThis is kick ass! I can think of some incredible use cases I could put to work today!
- hacksOfSumit 7y agoGo ahead :-)
- stevenzhu 7y agoWould be good if wkt can also be supported as input
- hacksOfSumit 7y agothanks, I put it on the list
- allthetime 7y agoLooks nice! Sexier than geojson.io, but, as others have pointed out, you need to get it up to feature parity before a lot of us would consider using it for serious work. I'll try it out and send some more feedback your way.
- hacksOfSumit 7y agowill do - it's v1 and we will get there
- wesleyfsmith 7y agoThis seems very similar to geojson.io . I'm curious, are you leveraging their source somehow?
- hacksOfSumit 7y agonope. Not at all.
