I briefly worked on collecting orthoimagery a couple of years ago. It started from [this](https://github.com/diegoripley/canada-orthoimagery). Current data processing pipeline is being defined, but you can preview some of the datasets from the process. I briefly worked on collecting orthoimagery a couple of years ago. It started from [this](https://github.com/diegoripley/canada-orthoimagery). Current data processing pipeline is being defined, but you can preview some of the datasets from the process.
Here is a table of some of the resulting datasets. ## Development Environment
While a key goal is to utilize open source as much as possible, We utilize the proprietary software [MapTiler Engine Pro](https://www.maptiler.com/engine/pricing) as it is superior to current open source solutions. A limitation is that we are limited to 8 CPU cores for rendering of the map tiles.
## Specifications of Tile Packages
The specifications for the tile packages are defined in this code.

## The Plan
# The Plan The plan is to include the original dataset, for example, the orthoimagery files from [Vancouver](https://opendata.vancouver.ca/explore/dataset/orthophoto-imagery-2022/information/) are provided in MrSID and ECW file formats, which are proprietary and require special drivers being used. I am looking into using formats such as [Cloud Optimized GeoTIFFs](https://cogeo.org/), but I have to make sure that there is no degradation of visual quality in the process. I hope to experiment with multispectral data in the future.

Look through https://github.com/dataforcanada/process-statcan-data.
Look through our [process-statcan-data](https://github.com/dataforcanada/process-statcan-data) repo for the datasets processed. There is still lots of work to do to make it ready for systems.
