Digital elevation models, orthophotos, and differencing results to analyze the effect of land cover type on 3D deformation recovery from synthetically deformed high-resolution satellite optical imagery

Synthetic earthquake deformation was imposed on high resolution (~0.5 m/pixel)orthoimagery and digital elevation models (DEMs) for two regions of the Garlock fault in the east and west. This repository contains the input and result rasters for the analysis, further described in Hanagan et al. (2025): "Effect of land cover type on 3D deformation recovery from synthetically deformed high-resolution satellite optical imagery." [doi coming soon with full suggested citation] DEMs and orthophotos were derived from high-resolution WorldView-1 and WorldView-2 ((C)2019,2020,2022,2023 Maxar) satellite imagery. Files in the data release with accompanying descriptions: -Region {East or West} -Orthos.zip Contains orthophotos for sub-pixel correlation. Rasters are labeled by date (YYmonDDHHMMSS), region (East or West), and (if applicable) whether they have been deformed: YYmonDDHHMMSSGarlock{Region}{Deformed}OrthoEPSG4326.tif -Modeled.zip Contains the modeled displacements as described in the main text. Rasters are labeled by region and component of measured displacement (east-west = EW; north-south = NS; up-down = UD): {Region}d{component}_EPSG4326.tif -DEMs.zip Contains DEMs for sub-pixel correlation and differencing. Rasters are labeled by date (YYmonDDHHMMSS), region (East/West), and (if applicable) whether they have been deformed: YYmonDDHHMMSSGarlock{Region}{Deformed}DEMEPSG4326.tif -MicmacResultsPostProcessed.zip -Stacked Contains the stacked orthophoto displacement results as described in the main text and the summed correlation score. The summed correlation raster is labeled CorrelStackedEPSG4326.tif. Rasters are labeled by component of measured displacement (east-west = EW; north-south = NS; up-down = UD): {component}DispStackedEPSG4326.tif -StackedFiltered Contains the stacked, bilaterally denoised, and bandpass filtered orthophoto displacement results.

Displacement rasters are labeled by component of measured displacement (east-west = EW; north-south = NS; up-down = UD): {component}micmacEPSG4326.tif -DEM Contains the displacement results and correlation scores from sub-pixel correlation and DEM differencing of DEM pairs as described in the main text.
