Pozyx GeoTIFF Viewer
Visualize and validate your GeoTIFF files directly in the browser.
This free online GeoTIFF viewer lets you quickly check how your map or floorplan aligns on a global map without the need for GIS software.
Why We Built This Tool
At Pozyx, we work every day with digital floorplans, high-precision maps, and georeferenced imagery to power real-time location systems (RTLS) and asset tracking solutions.
When we looked for simple tools to preview and validate GeoTIFFs online, we couldn’t find one that worked the way we wanted. Most available viewers were limited, inaccurate, or didn’t support rotation and correct scaling. Other options like QGIS are powerful, but require a full installation and some setup before you can properly display a GeoTIFF on a global map. Even then, we found that the image quality or coordinate accuracy sometimes wasn’t ideal for quick validation.
We built this lightweight web-based tool to make it fast and easy to view a GeoTIFF correctly positioned on a map. For very large files or professional geospatial processing, we still recommend using QGIS or similar GIS tools, but for quick checks, this viewer provides an instant and accurate alternative.
Sample GeoTIFFs to Test
What This Viewer Supports
- Standard GeoTIFF files (RGB or RGBA raster data)
- Embedded coordinate reference systems (CRS), including EPSG:4326, EPSG:3857, and UTM projections
- 16-bit and 8-bit imagery, with automatic color stretching for visualization
- Rotation and affine transforms, using GeoTransform or ModelTransformation metadata
- NoData transparency and adjustable opacity
- Large files, automatically downscaled for browser rendering, note that it may take a long time to load.
What it Does Not Support
- Cloud Optimized GeoTIFF streaming (COG) (local file upload only)
- Scientific rasters with more than four bands
- Advanced rendering or symbology (as provided by desktop GIS software)
These limitations keep the viewer lightweight and fast for practical use cases such as validating building floorplans, aerial imagery, or satellite layers before importing them into the Pozyx Platform.
How This Connects to The Pozyx Platform
The same technology used here powers the Pozyx Mapping Service, which allows users to:
- Upload and georeference image floorplans or high-resolution aerial photographs of industrial sites, warehouses, or construction areas for use in asset and vehicle tracking
- Upload GeoTIFFs directly to align detailed map imagery with real-world coordinates
- Visualize indoor and outdoor maps together in a unified coordinate system
- Manage multi-floor and 3D floorplans for complex environments
- Overlay real-time location data from UWB, BLE, or GPS trackers
- Define zones, geofences, and areas of interest to support location-aware workflows
This viewer demonstrates the core of Pozyx’s geospatial data handling, which brings together maps, location tracking, and context to provide accurate visibility across all levels of your operation.
