modules

spymicmac contains the following modules, organized roughly by what they are used for.

photogrammetry software

The following modules are used for interfacing with different photogrammetric processing software. In spite of the name, spymicmac can also be used to help prepare files for using Ames Stereo Pipeline, especially for processing panoramic camera images.

• spymicmac.micmac: for running mm3d commands and reading/writing XML files used by MicMac.

• spymicmac.register: for finding GCPs to register images to reference datasets

• spymicmac.orientation: for reading MicMac orientation directories and transforming coordinate systems

• spymicmac.asp: for preparing camera files for ASP.

declassified images

The following modules are primarily used for working with declassified datasets:

• spymicmac.preprocessing: for pre-processing KH-9 Hexagon mapping camera and declassified panoramic camera files.

• spymicmac.declass: for various metadata information about declassified datasets

reference data

The following modules are used for preparing/accessing reference datasets:

• spymicmac.data: for accessing reference datasets, including USGS footprints, Copernicus 30m DSM tiles, and the Polar Geospatial Center DEMs, ArcticDEM and REMA.

• spymicmac.ee_tools: (in progress) for accessing reference images and datasets using Google Earth Engine.

image processing

The following modules are primarily used for image processing, resampling, and feature matching:

• spymicmac.image: for radiometric processing and image mosaicking

• spymicmac.resample: for resampling images

• spymicmac.matching: for matching templates or keypoints between images
