What Are Cloud Optimized Point Clouds and GeoTIFFs?
And Why Should You Care?
If you’ve ever worked with massive geospatial datasets—think LiDAR scans or satellite imagery—you know they can be heavy, slow, and hard to handle. Downloading gigabytes of data just to extract a tiny area of interest can be frustrating. That’s where Cloud Optimized formats come in—designed to make working with big spatial data smoother, smarter, and faster.
Two of the most exciting developments in this space are:
Let’s break down what these are and why they’re game-changers.
Cloud Optimized GeoTIFF (COG): Fast Access to Raster Data
A GeoTIFF is a common format for storing raster geospatial data—think of it like a regular image file, but with built-in geographic metadata. But traditional GeoTIFFs are big and clunky. If you want to access a small region, you usually need to download the whole file first.
Cloud Optimized GeoTIFFs solve this by reorganizing the internal structure of the file to enable:
✅ Byte-range access – Tools can request only the portion of the file needed, directly over HTTP.
✅ Tiling and overviews – Pre-generated lower-res versions make zooming fast and efficient.
✅ Cloud-native workflows – Stream data straight into your applications without downloads.
Cloud Optimized Point Cloud (COPC): Smarter LiDAR in the Cloud
LiDAR and other 3D sensors generate point clouds—millions or billions of XYZ points with attributes like intensity or classification. Traditional LAS/LAZ files aren't optimized for cloud access, making them difficult to scale in web-based or distributed processing environments.
Cloud Optimized Point Clouds (COPC) are the solution. They’re built on LAZ but add a spatial hierarchy that enables:
✅ Spatial indexing – Quickly access just the points you need.
✅ Multi-resolution support – Start with low detail, stream more as needed.

✅ No backend server required – Just a smart client and a cloud storage bucket.
✅ Compatibility – Supported by tools like PDAL, Potree, Cesium, and Entwine.
Real-World Example: Detekt.it and Detekt 2.0
A great example of these formats in action is Detekt.it, a geospatial AI company transforming how mobile mapping data is used in urban and infrastructure settings. With the launch of Detekt 2.0, they’ve fully embraced COG and COPC to turbocharge their workflows.
By leveraging these cloud-optimized formats, Detekt is able to:
Whether it’s detecting road damages, extracting street markings, or analyzing infrastructure conditions, cloud optimization helps Detekt.it move from raw data to actionable insights at scale.
Why This Matters
COG and COPC are key building blocks for the future of cloud-native geospatial infrastructure. They:
Whether you're working in urban planning, autonomous driving, environmental monitoring, or digital twins—these formats let you focus on insights, not infrastructure.
Final Thoughts
Both COG and COPC are open standards, gaining traction fast in the geospatial community. Tools like GDAL, QGIS, PDAL, and Cesium already support them, and companies like Detekt.it are showing what’s possible when you combine smart formats with intelligent workflows.
If your current workflow still relies on downloading bulky files and running local scripts, it might be time to upgrade. The cloud has changed how we think about access and performance—and now, thanks to formats like COG and COPC, geospatial data is finally catching up.
