FAQ
Do you support EWKB (SRID embedded)?
Yes. If your WKB includes an SRID, we detect and show it. For non-4326 SRIDs, Auto PRJ mode omits the .prj to avoid writing the wrong CRS.
Is my data uploaded?
No — everything runs locally in your browser.
Why is there a Polygon-only toggle?
Shapefiles can store points/lines/polygons. If you only want polygons, enable the filter. If your WKB is not a polygon, you must disable it.
Can I open the output in QGIS?
Yes. Download the .zip and open it directly in QGIS.
Want to order satellite data for your polygons?
ClearSKY uses data fusion to deliver cloud-free imagery and robust time series at scale. Upload your polygons and place orders in minutes.
