# RPCM - Rational Polynomial Camera Model Python implementation of the Rational Polynomial Camera (RPC) model for optical satellite images. [Carlo de Franchis](mailto:carlo.de-franchis@ens-paris-saclay.fr), Gabriele Facciolo, Enric Meinhardt-Llopis (Centre Borelli, ENS Paris-Saclay, Université Paris-Saclay) 2013-21 `rpcm` is a Python library and command line tool for geolocating satellite images with RPCs. Its main source code repository is https://github.com/centreborelli/rpcm. # Installation To install `rpcm` from PyPI: pip install rpcm Alternatively, to install `rpcm` from sources: git clone https://github.com/centreborelli/rpcm.git cd rpcm pip install -e . # Usage `rpcm` is a Python library that can be imported into other applications. A Jupyter notebook tutorial covering the main features of the library is included (TODO). `rpcm` also comes with a Command Line Interface (CLI). The `rpcm` CLI has an extensive help that can be printed with the `-h` and `--help` switches. $ rpcm -h usage: rpcm [-h] {projection, localization, crop, footprint, angle} ... Some CLI usage examples can be found in `tests/tests.sh`. There are several subcommands, `projection`, `localization`, `crop`, `footprint`, `angle`, each of which has its own help. ## Projection $ rpcm projection -h usage: rpcm projection [-h] [--lon LON] [--lat LAT] [-z Z] [--points POINTS] [--crop CROP] [--svg SVG] img positional arguments: img path or url to a GeoTIFF image file with RPC metadata optional arguments: -h, --help show this help message and exit --lon LON longitude --lat LAT latitude -z Z altitude, in meters --points POINTS path to a 2/3 columns txt file: lon lat [z] --crop CROP path to a tif crop previously produced by rpcm. Image coordinates are computed with respect to this crop. --svg SVG path to an svg file where to plot projected points. ## Localization $ rpcm localization -h usage: rpcm localization [-h] [-x X] [-y Y] [-z Z] [--points POINTS] [--crop CROP] img positional arguments: img path or url to a GeoTIFF image file with RPC metadata optional arguments: -h, --help show this help message and exit -x X horizontal pixel coordinate (i.e. column index) -y Y vertical pixel coordinate (i.e. row index) -z Z altitude, in meters --points POINTS path to a 3 columns txt file: x y z --crop CROP path to a tif crop previously produced by rpcm. Image coordinates are interpreted with respect to this crop. ## Crop $ rpcm crop -h usage: rpcm crop [-h] [-z Z] img aoi crop positional arguments: img path to a GeoTIFF image file with RPC metadata aoi path to geojson file defining the area of interest (AOI) crop path to the output cropped tif image optional arguments: -h, --help show this help message and exit -z Z altitude of the crop center ## Footprint $ rpcm footprint -h usage: rpcm footprint [-h] [-z Z] img positional arguments: img path or url to a GeoTIFF image file with RPC metadata optional arguments: -h, --help show this help message and exit -z Z altitude, in meters ## Angle $ rpcm angle -h usage: rpcm angle [-h] [--lon LON] [--lat LAT] [-z Z] img1 img2 positional arguments: img1 path to a GeoTIFF image file with RPC metadata img2 path to a GeoTIFF image file with RPC metadata optional arguments: -h, --help show this help message and exit --lon LON longitude --lat LAT latitude -z Z altitude # Common issues _Warning_: A `rasterio` issue on Ubuntu causes the need for this environment variable (more info on [rasterio's github](https://github.com/mapbox/rasterio/issues/942)): export CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
