OpenStreetMap (OSM) is greater than the basemap you see on osm.org or in different geospatial companies. The database behind the map is stuffed with crowdsourced spatial information with systemized tagging that interprets into attributes in GIS techniques. For information analysts and cartographers who wish to entry datasets from OSM to be used in QGIS or different comparable purposes, HOT’s export instrument simply bought rather more useful!
In case you are in search of dependable OSM information in varied file codecs which might be simple to obtain in a couple of simple steps and a few minutes, new options have been added to the HOT Export Software! HOT’s developer, Kshitij, has been working for a variety of months on these enhancements, and we wish to ship an enormous because of him!
Watch the Walkthrough that can information you thru all of the options and discover them your self! In case you have any suggestions, get in contact by including a problem to Github or becoming a member of #export-tool Slack channel.
Now we have additionally defined all of the updates under with screenshots.
1. Export OSM Information with three new codecs (FlatGeobuf, CSV, and SQL)
- Flat Geobuf output could be very quick in comparison with shapefile, enabling customers to do spatial operations with spatial indexes. Export Software now offers OSM information in flageobuf format
- CSV output might be helpful for the information analyst and anybody considering utilizing osm tagging information of their analysis/ work/schooling.
- SQL output might be very helpful for programmers/visualizers who wish to run their very own queries and allow spatial evaluation utilizing the highly effective options of PostGIS.
2. Obtain every thing within the Space
The Export instrument updates introduce a brand new function permitting customers to obtain all accessible OSM options throughout the space. You may make the most of this Obtain all OSM information checkbox listed within the Information tab. This may embody all tags within the attributes, permitting you to filter the information you want or create a basemap out of exported options.
3. Get HOT Tasking Supervisor undertaking boundary on export instrument
Now, the Export Software can help Tasking Supervisor Venture ID as enter on to the search bar. The Venture ID needs to be adopted by the tm phrase. When a consumer selects a tasking supervisor undertaking ID as an space of curiosity, OSM information related to that undertaking might be exported.
4. Load particular person OSM options as a boundary
The export instrument additionally now offers you an choice to export information inside particular person OSM relation options. For instance, to deliver this municipality boundary from osm to the export instrument, you possibly can merely kind OSM and its id like the next and export your required options.
5. Get your export space fast data earlier than making an precise export request
The export instrument has a brand new function referred to as information completeness data. Once you create a geom or add within the export instrument, after a few seconds, you will note data simply above the system timestamp. We name it information completeness metrics attainable by varied sources may be discovered as listed right here. It would give a fast peek concerning the space the place you’re planning to export!
6. OSM Oauth2.0 implementation
Now we have carried out oauth2.0 authentication for OSM. This implies it is a massive change when it comes to the best way you login. You will want to sign off first after which log in once more to the export instrument, and every thing else ought to work because it used to! You will notice a banner like the next in your display.
7. New backend for the Export Software: Uncooked Information API (thrilling information for builders), Space threshold has been elevated by 50%
Uncooked Information API (https://ift.tt/SMBNsdp) now serves as a brand new backend to the OSM Export instrument for all the chosen codecs within the connected picture. I.e., GeoJSON, Shapefile, Geopackage, Google Earth KML, Flatgeobuf, and CSV. The world threshold for these codecs has additionally been elevated by 50%. You may entry API documentation right here. Github hyperlink right here and new structure diagram. The brand new API allows you to carry out nation exports, customized exports and likewise information completeness metrics for the Space. Garmin, OSM, and OSMAnd format will not be but accessible by the API and will not be as performant as others.
fAIr, the HOT Tasking Supervisor, and FMTM already use the uncooked information API, SQL, and Mbtiles! This new backend integration gives you quicker outputs for these chosen file codecs.
What extra are you able to anticipate from the export instrument?
We plan to publish one other weblog about information exports on the nation stage and its associated enhancement to HDX datasets. As all the time, we might love to listen to from you and what you consider these new developments! We might additionally welcome contributions from individuals to enhance the Export Software documentation right here.
