Landsat 4-5 TM L1 & L2
The Landsat Thematic Mapper (TM) sensor was carried onboard Landsats 4 and 5. It provides 6 spectral bands and 1 thermal infrared band. Landsat 4–5 TM Collection 2 includes both Level 1 and Level 2 products, supporting long-term global Earth observation from the early 1980s through 2012.
Landsat 4–5 TM Level 1 products provide radiometrically calibrated and orthorectified Top-of-Atmosphere (TOA) reflectance and brightness temperature data. Landsat 4–5 TM Level 2 products provide atmospherically corrected surface reflectance and surface temperature science products derived from Collection 2 Level 1 inputs.

Accessing Data
To access data you need to send a POST request to our process API. The requested data will be returned as the response to your request. Each POST request can be tailored to get you exactly the data you require. To do this requires setting various parameters which depend on the collection you are querying.
For an overview of all API parameters see the API Reference.
Endpoint Locations
| Service | Notes |
|---|---|
| services-uswest2.sentinel-hub.com/api | Global coverage from July 1982 to May 2012 |
Data type identifiers
Use the following values for input.data.type:
| Dataset | Identifier |
|---|---|
| Landsat 4–5 TM Level 1 | landsat-tm-l1 |
| Landsat 4–5 TM Level 2 | landsat-tm-l2 |
Filtering Options
This chapter explains the input.data.dataFilter object of the process API.
mosaickingOrder
Sets the order of overlapping tiles from which the output result is mosaicked. Note that tiles will in most cases come from the same orbit/acquisition. The tiling is done by USGS for easier distribution.
| Value | Description | Notes |
|---|---|---|
| mostRecent | (default) The pixel will be selected from the most recently acquired tile | |
| leastRecent | similar to mostRecent but in reverse order | |
| leastCC | The pixel is selected from the tile with the lowest cloud coverage | Estimated per tile (~31,000 sq. km); local cloud coverage may differ |
maxCloudCoverage
Sets the upper limit for cloud coverage in percent based on the precomputed cloud coverage estimate for each tile as present in the tile metadata.
tiers
| Value | Description |
|---|---|
| TIER_1 | selects Tier 1 products |
| ALL_TIERS | selected by default. selects Tier 1 and Tier 2 products |
Processing Options
