This repository provides systems-ready orthoimagery data for Canada, optimized for direct use in cloud-native geospatial applications and analysis pipelines. By standardizing diverse aerial and satellite imagery sources, it offers developers a consistent, high-performance visual baseline without the need for complex pre-processing.

Look through our d4c-datapkg-orthoimagery repo for the datasets that are currently being processed and datasets being acquired.
Although we prioritize open-source tools, we currently use MapTiler Engine Pro because it outperforms available open-source alternatives for this specific workflow.
The specifications for the tile packages are defined in this code.
Here is a table of some of the datasets created from the current process.
The objective is to standardize the source datasets used by Data for Canada processes. For instance, Vancouver’s orthoimagery is currently distributed in proprietary formats (MrSID and ECW) that require specialized drivers. We are currently evaluating open alternatives, such as Cloud Optimized GeoTIFFs, while ensuring that the conversion process preserves full visual fidelity. Future iterations will also explore the integration of multispectral data.
