Remote Sensing and Computer Vision: TorchGeo Data Loading
Making sense of huge amounts of remote sensing data is a job that many companies are working hard to solve. TorchGeo aims to fill the gap between deep learning and remote sensing.

Mapping Drought from Space – Part 2
In Part 1 of this series, we used satellite imagery to understand the impact of recent droughts on crop growth in the Canadian province of Alberta. In Part 2, we continue and extend our previous analysis, taking a more detailed view of specific areas in the province. But first it is worth mentioning why I’m …
Mapping Drought from Space – Part 1
2023 has been a landmark year for extreme weather around the world. Globally, there’s been deadly tropical cyclones and hurricanes, devastating floods, deadly cold snaps, record breaking ocean heat, and more. Here in Canada, a combination of severe heat waves and scarce precipitation have led to the worst wildfire season on record. Over 18.5 million …
Searching for Sasquatch
Recently we’ve been hearing reports about sightings of Sasquatch in and around Prince George, British Columbia. Being a geospatial company and because Prince George is home — one of them anyway — we thought we could lend a hand in confirming these reports.
STACLint: Validate your STAC
STACLint is an online validation tool for STACs. With it, you are able to validate STAC catalogs, collections, and items by supplying either a URL or JSON. The tool will crawl nested catalogs and report any errors it finds as it crawls through.
COG—Huh! What is it good for?
Cloud Optimized GeoTIFF (COG) are geotiff files, like satellite imagery, that have been processed in a manner that makes it easy to consume for internet processing applications (read cloud). It is the brainchild of some very smart people at very smart organizations (Amazon, Planet, MapBox, ESRI, USGS and the landsat-pds mailing list) and is supported by major processing software such as ESRI, Rasterio, Geoserver, QGIS and GDAL.
Image Be Gone
Images have been the currency of remote sensing since we started looking down at our Earth with sensors. Whether we were looking at stereo pairs for classifying stands of forest, or using LandSat images for the measuring our changing landscape the image has been an infrastructural necessity. Indeed, how on Earth would one do remote sensing without an image?
Data is Opinionated
Geospatial data in particular is opinionated. Now, opinion isn’t always a great thing. Opinion doesn’t mean you know better, it just means you have a particular view of the world and feel comfortable in maintaining that perspective.
The Great Space Race (Part 2 of 2)
This is the 2nd part in a series on the commercial satellite imagery sector. It’s a wild ride, but you can catch part 1 here. Some might argue that no one ever wanted the image; it is more of a by-product, a means to an end. Imagery consumers want to
The Great Space Race (Part 1 of 2)
TerraBella just arrived. Google’s rebranded (previously Skybox) remote sensing constellation is still in very active development with planned launches over the next few years. Their focus is on platform and information delivery rather than delivery of imagery. That’s amazing, but not because of the enormity of the problem, but […]
