Pléiades Primary (Download)

Description

A data block that provides non-rectified, unprojected high resolution 12-bit Pléiades images. Available since 2012, these images are acquired by the twin constellation Pléiades 1A and 1B on a daily basis anywhere on the globe. These images are optimal for users familiar with remote sensing processing methods who want to apply their own production techniques (orthorectification or 3D modelling).

See this block on the marketplace.

Dataset information

How it works

This block returns the RPC information encoded in the GeoTIFF file. To get the RPC data, use this code to return a dictionary with all the necessary information:

import rasterio as rio

tif_path = ""

with rio.open(tif_path) as src:
    rpc_dict = src.tags(ns="RPC")

For more information about geometric processing with RPCs, see the following online resources:

• Pléiades User Guide
• RPC Domain Metadata
• GIS StackExchange
• GDAL Documentation pages: RPC Georeferencing and gdalwarp

Compatibility

Don't combine primary data with processing blocks. The primary geometric processing level is the closest to the natural image acquired by the sensor. It's not orthorectified, while processing blocks expect orthorectified products.

Limitations

AOI size: The AOI must be larger than 0.1 km².

Geometric filter: The output image is clipped to the AOI bounding box, so the image gaps will be padded with zeros until the bounding box is covered. Depending on the AOI shape and irregularity, the final output image might be larger and the credit consumption will slightly increase.
