FAQ
Do I need to upload my KMZ?
No. Everything runs locally in your browser.
What is KMZ?
KMZ is a ZIP file that contains KML (often doc.kml) plus optional resources.
Which KML file inside the KMZ is used?
doc.kml is preferred; otherwise the first .kml found is used.
Which CRS is used?
KML/KMZ uses WGS84 (EPSG:4326). The download includes a WGS84 .prj.
My KMZ contains points/lines — can I export polygons only?
Yes. Enable polygon-only export to keep just boundaries/AOIs.
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.
