Order catalog data

Overview

Catalog data are archive geospatial data that have been captured in the past.

You can also place an order using the API.

Step 1. Choose a catalog collection

1. Open the console and go to Catalog.
2. To see all scenes that intersect with a specific area, define an AOI. The minimum AOI size is 0.1 km².
3. If you want to specify a date, maximum cloud coverage, or search for specific collections, click Filters to set up search parameters.

Step 2. Request access

If you want to order the chosen collection for the first time, and it is restricted, you need to request access to it. For more information on access requests, see Restrictions.

An email from the Customer Success team usually takes up to 3 days. You can review your access request status on the Access requests page.

Step 3. Accept a EULA

If you want to order the chosen collection for the first time, you need to accept its end-user license agreement (EULA). For more information on license agreements, see EULAs.

Step 4. Add a collection to the cart

1. Select a collection. Note asset delivery time, 10 minutes or up to 24 hours.
2. Analyze the low resolution scene preview to evaluate the overall cloud cover. You will only be charged for the segment that intersects with your AOI, not the whole scene.
3. Choose an image type, one or several, and click Add to Cart.
4. Click Checkout. You won't be charged at this step.
5. Check the order summary and click Order for [the amount of] Credits.

If you have enough credits, then the stated amount will be deducted from your balance. If the order fails, the credits will be returned to your balance.

Analytic and display types of images

TripleSat collection

Images from TripleSat are only delivered in analytic configuration. They differ in bit depths, 8 or 16 bits. These images aren't orthorectified or atmospherically corrected.

TripleSat analytic images are:

• Georectified — put into the WGS84 coordinate system.
• Radiometrically corrected — radiometric issues, such as stripe noise, are eliminated through basic preprocessing.
• Sensor corrected — sensor noise, modifications, and lens distortion are removed from them.

Analytic TripleSat images provide a geolocation accuracy of under 20 m CE90 at nadir. The CE90 standard implies that at least 90% of the points captured will fall within <20 m from the targeted point.

If you order a TripleSat analytic image, you will receive 2 files:

• A 4-band multispectral image that includes RGB and NIR bands.
• A panchromatic image that combines all three RGB bands to provide a better spatial resolution.

Pléiades Neo, Pléiades, and SPOT collections

Images in these datasets are orthorectified, which means sensor motion and terrain distortions are removed from them. Both analytic and display images are corrected for systematic atmospheric effects — for example, bluish effects — but display images also have a true color curve applied to optimize the visual quality of an image.

Analytic images have a more stable contrast and can be used to extract physical properties, such as radiance or reflectance — for example, in vegetation health monitoring. Also, they're more suitable for time series analysis. Display images look better visually and can be used to extract features — for example, in car detection or infrastructure monitoring.

If you order an analytic image, you will receive 2 files:

• A 4-band multispectral image that includes RGB and NIR bands.
• A panchromatic image that combines all three RGB bands to provide a better spatial resolution.

In a display image, panchromatic and multispectral images are combined into one.
