SPOT 6/7 is composed of two twin satellites orbiting the Earth 180° apart. The satellites deliver 1.5 m optical imagery and offer a daily revisit capability to any point on the globe.
SPOT 6/7 data with its high spatial resolution is suitable for a range of remote sensing applications such as vegetation monitoring, precise mapping, risk and disaster management.
|Spatial resolution||1.5 m for panchromatic band and 6 m for all other bands|
|Sensor||Multispectral Imager, 5 bands: panchromatic, Blue, Red, Green and Near-Infrared band|
|Revisit time||Up to a daily revisit of any point on the globe.|
A data acquisition must be tasked, data is not acquired systematically.
|Data availability||Since September 2012|
|Measurement||Top of the atmosphere (TOA) reflectance|
|Common usage/purpose||vegetation monitoring, risk and disaster management, urban and mapping applications, civil engineering|
The SPOT products are released under the license available here.
The process of purchasing of SPOT data in Sentinel Hub goes as follows:
- Check the pricing and conditions. If you would like to buy bigger area send us an e-mail and we will prepare a custom offer.
- Go to the "Billing" section in your SH Dashboard and buy the Airbus SPOT plan.
- Once the payment is processed, we will send you a confirmation and you will be able to proceed with ordering the data.
To order SPOT data, please use our Third Party Import Data API.
SH uses the following settings when ordering SPOT data:
|Provider's parameter / tool||The values used by SH for ordering|
|crs||UTM zone corresponding to user defined bounds|
|processing level||SENSOR or ALBUM|
Note: If you would need any other SPOT product, please contact us.
Once your order is successfully finished the ordered data will be available in one of your BYOC collections and ready to be used. To access the data you will need the id of this collection.
Accessing of the SPOT data is similar to accessing any other BYOC data. All processing and filtering options listed there can be used. However, the settings specific for accessing of SPOT data are listed below.
|https://services.sentinel-hub.com/||Contains the data purchased by individual user|
Use the id of the BYOC collection into which your SPOT data was delivered as a value of parameter
input.data.dataFilter.collectionId in the
process API requests. See BYOC data access for more information.
This chapter will explain the bands and data which can be set in the evalscript input object:
Any string listed in the column Name can be an element of the
input.bands array in your evalscript.
|B0||Blue, 454-519 nm||6m|
|B1||Green, 527-587 nm||6m|
|B2||Red, 624-694 nm||6m|
|B3||Near Infrared, 756-880 nm||6m|
|PAN||Panchromatic, 455-744 nm||1.5m|
|dataMask||The mask of data/no data pixels (more).||N/A**|
The data values for each band in your custom script are presented in the units as specified here. In case more than one unit is available for a given band, you may optionally set the value of
input.units in your evalscript
setup function to one of the values in the
Sentinel Hub Units column. Doing so will present data in that unit. The Sentinel Hub
units parameter combines the physical quantity and corresponding units of measurement values. As such, some names more closely resemble physical quantities, others resemble units of measurement.
Source Format specifies how and with what precision the digital numbers (
DN) from which the unit is derived are encoded. Bands requested in
DN units contain the pixel values which are the result of ordering and preprocessing the data as explained in the chapter Ordering SPOT data. Note that resampling may produce interpolated values.
DN is also used whenever a band is derived computationally (like dataMask); such bands can be identified by having
DN units and
N/A source format.
For SPOT bands,
DN are the default and only unit. Reflectance values can be obtained for optical and panchromatic bands using the simple formula:
reflectance = DN / 10000.
Typical Range indicates what values are common for a given band and unit, however outliers can be expected.
|Band||Physical Quantity (units)||Sentinel Hub Units||Source Format||Typical Range|
|Optical and panchromatic bands||Scaled reflectance (unitless)||DN||UINT16||0 - 4000 |
Highly reflective pixels can have values above 10000.
|dataMask||N/A||DN||N/A||0 - no data|
1 - data
All mosaicking types are supported.
