View GeoTIFFs and orthomosaics on a map
Upload a GeoTIFF, orthomosaic, or elevation model and view it on an interactive map in your browser. No GIS software needed. Share with clients via a branded link.
No credit card required
How it works
Upload your GeoTIFF
Drag and drop your GeoTIFF, orthomosaic, DEM, or DSM. Swyvl detects the file type and coordinate system automatically.
View on an interactive map
Your raster is georeferenced and overlaid on an OpenStreetMap base layer. Zoom to full resolution. Pan to explore the full extent.
Share with clients
Generate a branded share link. Your client opens it in their browser and sees the same interactive map — no GIS software required.
Supported formats
| Format | Description |
|---|---|
| GeoTIFF | Standard georeferenced raster format used across GIS and remote sensing |
| Cloud Optimized GeoTIFF (COG) | Optimized for web viewing — loads only the visible portion for faster display |
| Orthomosaic | Georeferenced composite image from drone or aerial photography |
| DEM / DSM | Digital elevation and surface models for terrain analysis and visualisation |
What you see
Interactive Leaflet map
Your GeoTIFF is displayed on a zoomable, pannable map with smooth tile-based rendering.
Georeferenced overlay
The raster is placed at its real-world coordinates, overlaid on an OpenStreetMap base layer for context.
Zoom to full resolution
Zoom in to see every pixel of your orthomosaic. COG support means only the visible tiles are loaded.
OpenStreetMap base layer
Roads, buildings, and terrain for geographic context beneath your raster data.
Cloud Optimized GeoTIFF support
A Cloud Optimized GeoTIFF (COG) is structured so that only the portion visible at the current zoom level is loaded from storage. This means your browser doesn't need to download a multi-gigabyte file before displaying it.
Progressive loading
See a low-resolution overview instantly, then load detail as you zoom in — just like a web map.
Less bandwidth
Only the tiles you're viewing are fetched. A 10 GB orthomosaic loads as fast as a small image at overview zoom.
No full download
Clients view the raster without downloading the full file. They can still download it if they need the raw data.
Share with clients
Generate a branded share link for any GeoTIFF or session. Your client opens it in their browser and sees the interactive map — no GIS software or account required. Learn more about sharing GeoTIFFs online.
Branded delivery
Add your logo and brand colours. Paid plans remove "Powered by Swyvl" for a fully white-labelled experience.
Password protection
Restrict access with a password. Only people with the link and password can view your deliverables.
Download tracking
See who viewed and downloaded your files. Full audit trail with timestamps, IP addresses, and location data.
Frequently asked questions
Can I view GeoTIFF files in a browser?
Yes. Swyvl renders GeoTIFF files on an interactive Leaflet map directly in your browser. Your raster is georeferenced and overlaid on an OpenStreetMap base layer — no GIS software required.
What is a Cloud Optimized GeoTIFF?
A Cloud Optimized GeoTIFF (COG) is a GeoTIFF file structured so that only the portion visible at the current zoom level is loaded, rather than downloading the entire file. This means faster loading and less bandwidth, especially for large orthomosaics and elevation models. Swyvl supports COGs natively.
Do I need GIS software to view orthomosaics?
No. Swyvl displays orthomosaics on an interactive map in your browser. You can zoom to full resolution, pan around the site, and share a link with clients who can view the same map without any software or account.
What coordinate systems are supported?
Swyvl auto-detects the coordinate reference system (CRS) embedded in your GeoTIFF and reprojects it for display on the web map. Common CRS projections like WGS 84, UTM zones, and state plane coordinate systems are all supported.
