Buyer's Guide
How to choose a satellite imagery provider
There's no single "best" provider — only the best fit for what you're trying to see, how often, and how you'll use the result. This guide walks through the criteria that matter, the difference between commercial and open data, and a simple process for narrowing the field.
Start here
Start with your use case, not the satellite
The most common mistake is shopping for the highest resolution available. Detail is only one variable — and often not the deciding one. Before comparing providers, get specific about the job: What do you need to detect, how large an area, how often, and how quickly?
Mapping a city block for inspection is a different problem from monitoring a 10,000 km² region for change every week, or confirming activity at a port through cloud cover. Each points toward a different sensor, resolution, and revisit profile — and therefore a different provider. Once the use case is clear, the criteria below sort themselves out quickly.
What to weigh
The criteria that matter
Seven dimensions to compare across providers. Rank them by your use case — rarely will one provider top every list.
Resolution
How much detail each pixel holds — from 15 cm very-high-resolution optical down to 10 m open data. Sharper isn't always better: wide-area monitoring rarely needs sub-meter detail, while infrastructure inspection does. Higher resolution also means higher cost and smaller coverage per scene.
Revisit rate
How often a provider re-images the same place. Large constellations can revisit daily or several times a day — essential for change detection and time-sensitive work, less so for a one-off map. Tasking a new capture is faster with operators that fly more satellites.
Sensor type
Optical looks like a photo; SAR (radar) sees through cloud and darkness; hyperspectral reads the materials in a scene; thermal senses heat. The right sensor often matters more than the sharpest resolution — no amount of optical detail helps if your target is under persistent cloud.
Coverage & revisit history
Geographic reach plus the depth of the archive. Some providers excel in specific regions; others offer truly global collection. A deep historical archive matters whenever you need to look backward — measuring change, establishing a baseline, or investigating a past event.
Licensing & usage rights
How you're allowed to use the imagery — internal analysis only, redistribution, derivative products, or public display. Commercial licenses vary widely between operators, and the terms can matter as much as the price. Open data is typically free to use with attribution.
Pricing & access
How the data is priced and how easy it is to buy. Working with operators directly can mean contracts, minimum orders, and sales cycles. Aggregating platforms let you buy from many providers at once — often per km², with transparent pricing and no commitment.
APIs & integrations
How cleanly imagery flows into your tools and workflows. Modern providers and platforms expose APIs so you can search, order, and stream data directly into your GIS, analytics pipeline, or application — instead of managing one-off file deliveries.
Two categories
Commercial vs. free & open imagery
Before comparing individual providers, decide which category your project needs. Many workflows use both — open data for broad context, commercial for the detail.
The process
How to evaluate, step by step
Define the target and the area
Name what you need to detect and how large an area it covers. This sets your minimum resolution and rules out sensors that can't resolve it — or scenes too small to be economical.
Decide how often you need it
One-time capture, or recurring monitoring? Frequency determines whether you need a high-revisit constellation or a single tasked image, and it drives cost more than most buyers expect.
Match the sensor to the conditions
Cloud, darkness, or material detection change everything. Choose SAR for all-weather reliability, hyperspectral for composition, thermal for heat — optical only when conditions cooperate.
Check archive vs. tasking
If the moment you care about has passed, you need archive depth. If it's in the future, you need tasking and a realistic capture window. Many providers offer both; some lean heavily one way.
Confirm licensing and delivery
Make sure the usage rights cover how you'll use the imagery, and that it arrives in a format and pipeline your team can actually work with — ideally via API.
Compare on one platform
Rather than running separate procurement with each operator, compare providers side by side in one place. SkyWatch lets you search, preview, price, and order across providers without individual contracts.
Compare every provider in one place
