Happy Halloween! A new release of UCR-Star is now available with new location-aware features. 1) Go to my location. 2) Search for any location on the map. 3) Download a subset of the data in any country, state, or province. You might need to refresh your browser.

On Tuesday Nov 1, I will give a 90-minute tutorial along with @TomalMajumder on reproducible experiments with @UCRStar and #Spider at the #SpatialAPI workshop collocated with @SIGSPATIAL_GIS. See you in Seattle. https://t.co/Xa5vaFuRIz

UCR-Star and Spider will be down today 10:00 AM - 1:00 PM Pacific Time (17:00-20:00 UTC) for maintenance.

[ucrstar @ucrstar]

@aocalderon1978 @birdmapper We apologize for the brief downtime. There was an issue with #OpenLayer that was fixed. You might need to refresh the page to load the updates.

[ucrstar @ucrstar]

@NASAClimate That's the power of visualization!

[ucrstar @ucrstar]

@j_igarashi @mikel @Google @openstreetmap Now that @Microsoft released a building dataset in Africa, we can compare. It seems that Google dataset has a higher coverage but lower accuracy. However, you can use the confidence parameter in @Google's to prioritize quality. https://t.co/Us7U1bOMEV https://t.co/YvA2KK0MsB

[ucrstar @ucrstar]

@Antidius36 @undertheraedar Check also the newest addition to UCR-Star, the Google building dataset in Africa with more than 500 million buildings overall. The coverage is much higher than the Microsoft building dataset but the quality is a different story.

Check out our newest dataset, 516 million buildings in Africa extracted from satellite imagery by @GoogleAI team. This dataset has a higher coverage than the Microsoft building dataset. We'll let the community judge the quality. #Africa #OpenData #GIS

[ucrstar @ucrstar]

@Antidius36 @undertheraedar Right! The datasets for Tanzania, Keyna, and Uganda are now available on UCR-Star as well. https://t.co/fUK1807rhr

[ucrstar @ucrstar]

@undertheraedar Check out the most recent addition, ML Buildings dataset which covers most of the world. Some parts are still not covered, e.g., Nigeria, Germany, France, and UK. https://t.co/7JzTUfkKUS

[ucrstar @ucrstar]

@Antidius36 @undertheraedar The new ML Buildings dataset covers most of the world. However, big parts of Europe are also still not covered, e.g., Germany, UK, and France. You can explore and download all these datasets at UCR-Star. https://t.co/7JzTUfkKUS

[ucrstar @ucrstar]

@xettasoft You can explore and download these datasets, and hundreds of others, at UCR-Star. https://t.co/fUK1807rhr
Nigeria buildings are not available from @Microsoft but you can find some data from @openstreetmap, also at UCR https://t.co/WhoU64irvo

[ucrstar @ucrstar]

@thepowerofgis @giswqs There are some buildings in the OpenStreetMap dataset. Check it out and download from UCR-Star. https://t.co/hlFhsC9dB2

[ucrstar @ucrstar]

@samapriyaroy Awesome work! Thanks for sharing. You can also explore and download all the Microsoft Building datasets at UCR-Star in many standard formats including Shapefile, KML, GeoJSON, and CSV. https://t.co/RXwL3bv4zO

[ucrstar @ucrstar]

@OurRadiantEarth @giswqs @Microsoft Thanks for sharing this helpful tutorial. You can also download this dataset (and hundreds others) in full or in part from UCR-Star in any standard geospatial file format including KML, Shapefile, CSV, and GeoJSON. https://t.co/RX3HwI9d8q
