Upload Limits
File size limits depend on your plan. Free accounts can upload files up to 50 MB. Pro accounts up to 500 MB. Team and Enterprise accounts up to 2 GB. Files larger than these limits should be uploaded via cloud source connections.
Auto-Detection
GISOwl automatically detects coordinate reference systems (CRS), geometry types, and column mappings. If auto-detection fails, you'll be prompted to select the correct CRS and map columns manually.
