Deprecating Landsat 8
Planet is deprecating the Landsat-8 item types on Wednesday, May 22, 2024 with plans to formally end-of-life the item types on Wednesday, July 31, 2024. For more information and tips on migrating, see the Public Dataset Deprecation and Migration Plan.
Landsat 8 standard terrain-corrected scenes in path/row framing. This data set includes imagery from Landsat 8 satellite operated by USGS.
Products Overview¶
The Geometric Processing Subsystem (GPS) creates L1 geometrically corrected imagery (L1G) from L1R products. The geometrically corrected products can be systematic terrain corrected (L1Gt) or precision terrain-corrected products (L1T). The GPS generates a satellite model, prepares a resampling grid, and resamples the data to create an L1Gt or L1T product. The GPS performs sophisticated satellite geometric correction to create the image according to the map projection and orientation specified for the L1 standard product.
Landsat 8 data is packed into zip files by band. All data is passed through in the original provider’s format, so please visit USGS for more details.

Data available from the U.S. Geological Survey. See USGS Visual Identity System Guidance for further details.
Item Properties¶
| Property Name | Description | Type |
|---|---|---|
| _permissions | Assets available for the item which the authenticated user has permission to download. | array |
| geometry | Geographic boundary of the item's footprint, formatted as a GeoJSON polygon. | json |
| id | Globally unique item identifier. | string |
| acquired | Timestamp representing the date and time of acquisition (in UTC). | datetime |
| anomalous_pixels | Ratio of pixels that may have errors. Represented spatially in the UDM. | double |
| cloud_cover | Ratio of the pixels covered by clouds. | double |
| collection | Landsat collection number. | integer |
| columns | Number of columns in the image. | integer |
| data_type | The processing level of the product. | string |
| epsg_code | Ortho tile grid cell that the item is located in (not used if Scene). | integer |
| gsd | Ground sample distance - the distance between pixel centers as measured on the ground in meters. | double |
| instrument | Name of the satellite instrument used to collect the image. | string |
| item_type | Name of the item type. | string |
| origin_x | ULX coordinate of the extent of the data. The coordinate references the top left corner of the top left pixel. | double |
| origin_y | ULY coordinate of the extent of the data. The coordinate references the top left corner of the top left pixel. | double |
| pixel_resolution | Pixel resolution of the imagery in meters. | double |
| processed | Timestamp that the item was processed. | datetime |
| product_id | Unique identifier of the product. | string |
| provider | Name of the item provider (e.g. “planetscope”, ”rapideye”). | string |
| published | Timestamp that the item was published to the Planet API. | datetime |
| quality_category | Planet image quality metric: Standard or Test. To qualify for "standard" image quality an image must meet a variety of quality standards, for example: PAN motion blur less than 1.15 pixels, compression bits per pixel less than 3. If the image does not meet these criteria it is considered "test" quality. | string |
| rows | Number of rows in the image. | integer |
| satellite_id | Globally unique satellite identifier. | string |
| sun_azimuth | The angle of the sun, as seen by the observer, measured clockwise from the north (0 - 360). | double |
| sun_elevation | The angle of the sun above the horizon (0 - 90). | double |
| updated | Timestamp that the item record was last updated. | datetime |
| usable_data | Percentage of pixels that are usable, subtracting cloud cover and black fill. | double |
| view_angle | The satellite's across-track, off-nadir viewing angle. Positive numbers denote east, negative numbers denote west (-25 - +25). | double |
| wrs_path | Nearest WRS (Worldwide Reference System) path to the line-of-sight scene center. | integer |
| wrs_row | Nearest WRS (Worldwide Reference System) Row to the line-of-sight scene center. | integer |
