5. Geospatial scientists spend 80% of their time preparing data;
Descartes Labs eliminates the dominant source of friction.
– Data analysts spend 80% of their time simply finding and preparing data.
– Many satellite images are difficult to access; not "online"; must be requested
and downloaded.
– One satellite constellation may not be adequate; e.g., resolution, frequency,
sensor band.
– Archives contain raw, unprocessed images; lots of clouds, not registered or
calibrated.
– Machine learning requires clean and reproducible datasets, often in
combination with supercomputing capability.
6. Our geospatial analysis platform
A growing archive of analysis-ready images,
with historical records for back-testing
models.
Robust pipeline for continuous updating as
new images become available.
Multiple satellite image datasets integrated
into a single system.
Cloud-based data and services, ready-to-use
for data science teams anywhere.
Elastic computing model—scaling compute
resources quickly and only when needed.

10. GeoVisual search
t-SNE visualization of image chips
Divide the earth's surface
into (billions of) small,
overlapping images
Extract a "visual feature
vector" from each image
using a convolutional
neural network
Search for neighbors in this
feature space using either
direct search or locality-
sensitive hashing
