This guide provides instructions for switching from Landsat Collection 1 to Collection 2 data. Collection 2 has been fully available in Earth Engine since 2022 and no Collection 1 data has been produced by the USGS since December 31, 2021. Landsat Collection 1 is deprecated and all users are encouraged to migrate to Collection 2 as soon as possible.
Each Landsat Collection represents a version of the image archive processed with consistent methods and routines. As systems and processing algorithms improve, new collections are generated. In 2020, the USGS began reprocessing the archive to Collection 2. See the article "The 50-year Landsat collection 2 archive" in Remote Sensing of Environment to learn about the rationale behind the collections processing model and the contents and advancements provided by Collection 2.
The following sections describe the changes needed to migrate from Collection 1 to Collection 2 for each Landsat data product, including image and collection IDs, band names, new bands, band value scaling, and bitmask values. The content tabs within each section provide details for specific sensors.
Surface reflectance
OLI
Asset ID
Replace C01 with C02 and SR with L2 in image and collection IDs.
For example, Landsat 8 OLI Tier 1
(Landsat 9 OLI-2 was not included in Collection 1):
| Collection 1 | Collection 2 |
|---|---|
| LANDSAT/LC08/C01/T1_SR | LANDSAT/LC08/C02/T1_L2 |

Update code that selects bands whose names have changed, for example, the near-infrared band:
| Collection 1 | Collection 2 |
|---|---|
image.select('B5') |
image.select('SR_B5') |
Value scaling
Reflectance bands have new scaling factors. Collection 1 used a 0.0001
scale factor. Collection 2 uses a 2.75e-05 scale factor and -0.2 offset.
The thermal band also has new scale and offset factors. The following code
block defines a function to apply Collection 2 surface reflectance and
temperature band scaling factors and maps it over an image collection.
Code Editor (JavaScript)
var applyScaleFactors = function(image) { var opticalBands = image.select('SR_B.').multiply(0.0000275).add(-0.2); var thermalBand = image.select('ST_B10').multiply(0.00341802).add(149.0); return image.addBands(opticalBands, null, true) .addBands(thermalBand, null, true); } var srColScaled = srCol.map(applyScaleFactors)
Colab (Python)
def apply_scale_factors(image): optical_bands = image.select('SR_B.').multiply(0.0000275).add(-0.2) thermal_band = image.select('ST_B6').multiply(0.00341802).add(149.0) return image.addBands(optical_bands, None, True).addBands( thermal_band, None, True ) sr_col_scaled = sr_col.map(apply_scale_factors)
QA masking
Bit codes have changed for the QA bitmask (CFMASK). See the "Bitmask for QA_PIXEL" (Collection 2) and "Bitmask for pixel_qa" (Collection 1) sections in catalog entries for codes.
The following expression creates a cloud and shadow mask for a given image using the Collection 2 QA bitmask codes.
Code Editor (JavaScript)
var qaMask = image.select('QA_PIXEL').bitwiseAnd(parseInt('11111', 2)).eq(0)
Colab (Python)
qa_mask = image.select('QA_PIXEL').bitwiseAnd(int('11111', 2)).eq(0)
Radiometric saturation
Bit codes have changed for the radiometric saturation bitmask. See the "Bitmask for QA_RADSAT" (Collection 2) and "Bitmask for radsat_qa" (Collection 1) sections in catalog entries for codes.
Image properties
In the transition from Collection 1 to Collection 2, some image properties were added and some were removed. Properties for solar geometry were altered. See the following property comparison table to determine whether you need to modify your code to accommodate missing, added, or altered properties (e.g., in filtering or processing). Refer to the Image Properties tab in the product's catalog page for Collection 2 property descriptions.

| Collection 1 | Collection 2 |
|---|---|
| LANDSAT/LC08/C01/T1 | LANDSAT/LC08/C02/T1 |
Band names
Note band name changes and the addition of new bands.

Update code that selects bands whose names have changed, for example, the QA bitmask band:
| Collection 1 | Collection 2 |
|---|---|
image.select('BQA') |
image.select('QA_PIXEL') |
Value scaling
No changes required. Collection 1 and Collection 2 have the same scaling for raw DN reflectance and thermal values.
QA masking
Bit codes have changed for the QA bitmask. See the "Bitmask for QA_PIXEL" (Collection 2) and "Bitmask for BQA" (Collection 1) sections in catalog entries for codes.
The following expression creates a cloud and shadow mask for a given image using the Collection 2 QA bitmask codes.
Code Editor (JavaScript)
var qaMask = image.select('QA_PIXEL').bitwiseAnd(parseInt('11010', 2)).eq(0)
Colab (Python)
qa_mask = image.select('QA_PIXEL').bitwiseAnd(int('11010', 2)).eq(0)
Image properties
In the transition from Collection 1 to Collection 2, some image properties were added and some were removed. No property names were changed. See the following property comparison table to determine whether you need to modify your code to accommodate missing or added properties (e.g., in filtering or processing). Refer to the Image Properties tab in the product's catalog page for Collection 2 property descriptions.

image.select('BQA') |
image.select('QA_PIXEL') |
Value scaling
No changes required. Collection 1 and Collection 2 have the same scaling for raw DN reflectance and thermal values.
QA masking
Bit codes have changed for the QA bitmask. See the "Bitmask for QA_PIXEL" (Collection 2) and "Bitmask for BQA" (Collection 1) sections in catalog entries for codes (TM 5, for example).
The following expression creates a cloud and shadow mask for a given image using the Collection 2 QA bitmask codes.
Code Editor (JavaScript)
var qaMask = image.select('QA_PIXEL').bitwiseAnd(parseInt('11010', 2)).eq(0)
Colab (Python)
qa_mask = image.select('QA_PIXEL').bitwiseAnd(int('11010', 2)).eq(0)
Image properties
In the transition from Collection 1 to Collection 2, some image properties were added and some were removed. No property names were changed. See the following property comparison table to determine whether you need to modify your code to accommodate missing or added properties (e.g., in filtering or processing). Refer to the Image Properties tab in the product's catalog page for Collection 2 property descriptions (TM 5, for example).

Landsat Pre-Collection
The Earth Engine data archive contains Landsat Pre-Collection data. It can be identified by image and collection IDs that lack a collection component.
- Collection 1 / Collection 2:
LANDSAT/[MISSION]/[COLLECTION]/[PRODUCT](e.g.,LANDSAT/LE07/C02/T1) - Pre-Collection:
LANDSAT/[MISSION]_[PRODUCT](e.g.,LANDSAT/LE7_L1T)
If you are using Pre-Collection data, switch to Collection 2 as soon as possible. Use the information about Collection 2 throughout this guide to update your scripts.
Temporal composites
Earth Engine provides computed temporal composites (8-day, 32-day, and annual). There are a series of differences between those generated for Collection 1 and pre-Collection (PC/C1) and Collection 2 (C2). The code used to generate the C2 composites can be viewed on GitHub.
Surface reflectance composites
The C2 composites are generated from the USGS L2 surface reflectance product, whereas PC/C1 composites were made using top-of-atmosphere reflectance.
One collection for all instruments
The PC/C1 composites were separated into a set of temporal index composites for each instruments. This was primarily due to calibration differences between instruments. With C2 surface reflectance data, the inter-calibration is sufficient to combine are instruments together.
Strict filtering
More aggressive filtering for data quality is applied for the C2 composites, including:
- Limiting L7 to the range 1999–2017 due to orbital drift / scene acquisition time.
- Omitting L8 data before May 1, 2013 due to orbit stability issues.
- Omitting data with WRS_ROW ≥ 122 (no nighttime images).
- Omitting any pixels that are QA-flagged as anything other than clear.
- Omitting L4–L7 pixels with ATMOS_OPACITY > 300 (haze).
- Omitting L8–L9 pixels with any QA_AEROSOL issues.
- Omitting any pixels flagged as saturated or which have values that are out of bounds.
Median composites
The PC/C1 composites used a last-on-top compositing. Collection 2 composites use a median compositor.
Naming
The PC/C1 composite paths are in the form of
LANDSAT/INSTRUMENT/C01/T1_PERIOD_INDEX, while the C2 composites are in the form ofLANDSAT/COMPOSITES/C02/T1_L2_PERIOD_INDEX, where INSTRUMENT is one of LT04, LT05, LE07, or LC08 and PERIOD is one of 8DAY, 32DAY, or ANNUAL. As an example, the following table shows asset paths for C2 composites that roughly correspond to C1 LC08 annual composites for each INDEX. Recall that INSTRUMENT is not included in the C2 composites because all relevant data from L4–L9 are included in each composite.Collection 1 Collection 2 LANDSAT/LC08/C01/T1_ANNUAL_BAI LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_BAI LANDSAT/LC08/C01/T1_ANNUAL_EVI LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_EVI LANDSAT/LC08/C01/T1_ANNUAL_GREENEST_TOA LANDSAT/LC08/C01/T1_ANNUAL_NBRT LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_NBR LANDSAT/LC08/C01/T1_ANNUAL_NDSI Not produced because snow pixels are masked during the compositing process LANDSAT/LC08/C01/T1_ANNUAL_NDVI LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_NDVI LANDSAT/LC08/C01/T1_ANNUAL_NDWI LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_NDWI LANDSAT/LC08/C01/T1_ANNUAL_RAW LANDSAT/LC08/C01/T1_ANNUAL_TOA
