This driver can connect to Planet Labs Scenes API. GDAL/OGR must be built with Curl support in order for the PLScenes driver to be compiled.
The driver supports read-only operations to list scenes and their metadata as a vector layer per scene type ("ortho" for example). It can also access raster scenes.
PLScenes:[options]
Additionnal optional parameters can be specified after the ':' sign. Currently the following one is supported :
Name | Type | Description |
---|---|---|
id | String | Scene unique identifier. |
acquired | DateTime | The time that image was taken in UTC. |
camera.bit_depth | Integer | Bit depth with which the image was taken onboard the satellite. Currently 8 or 12. |
camera.color_mode | String | The color mode of the image as taken by the satellite. Currently "RGB" or "Monochromatic". |
camera.exposure_time | Integer | The exposure time in microseconds. |
camera.gain | Integer | The analog gain with which the image was taken. |
camera.tdi_pulses | Integer | The number of pulses used for time delay and integration on the CCD. Currently 0 (if TDI was not used), 4, 6, or 12. |
cloud_cover.estimated | Real | The estimated percentage of the image covered by clouds. Decimal 0-100. |
data.products.analytic.full | String | URL to download scene GeoTIFF of the "analytic" product. |
data.products.visual.full | String | URL to download scene GeoTIFF of the "visual" product. |
file_size | Integer | The size of the full image in bytes. |
image_statistics.gsd | Real | The ground sample distance (distance between pixel centers measured on the ground) of the image in meters. |
image_statistics.image_quality | String | Image quality category for scene. One of 'test', 'standard', or 'target'. |
image_statistics.snr | Real | The estimated signal to noise ratio. Decimal > 0. Values greater than or equal to 50 are considered excellent quality. Values less than 50 and greater than or equal to 20 are considered adequate quality. Values less than 20 are considered poor quality. |
links.full | String | URL to download scene GeoTIFF (same content as data.products.visual.full currently) |
links.self | String | URL to scene information |
links.square_thumbnail | String | URL to image thumbnail |
links.thumbnail | String | Link to image square thumbnail |
sat.alt | Real | The altitude of the satellite when the image was taken in kilometers. |
sat.id | String | A unique identifier for the satellite that captured this image. |
sat.lat | Real | The latitude of the satellite when the image was taken in degrees. |
sat.lng | Real | The longitude of the satellite when the image was taken in degrees. |
sat.off_nadir | Real | The angle off nadir in degrees at which the image was taken. |
strip_id | Real | A unique float identifier for the set of images taken sequentially be the same satellite. |
sun.altitude | Real | The altitude (angle above horizon) of the sun from the imaged location at the time of capture in degrees. |
sun.azimuth | Real | The azimuth (angle clockwise from north) of the sun from the imaged location at the time of capture in degrees. |
sun.local_time_of_day | Real | The local sun time at the imaged location at the time of capture (0-24). |

Scenes and their thumbnails can be accessed as raster datasets, provided that the scene ID is specified with the 'scene' parameter / SCENE open option. The product type (visual, analytic or thumb) can be specified with the 'product_type' parameter / PRODUCT_TYPE open option. The scene id is the content of the value of the 'id' field of the features of the 'ortho' vector layer
This functionality is a conveniency wrapper of the API for fetching the scene GeoTIFF
