This metadata describes EGMS Ortho, the third product level in the EGMS portfolio. EGMS Ortho is derived from EGMS Calibrated through a resampling procedure onto a 100 m grid, using data from both ascending and descending satellite orbits. This process generates two distinct layers: one representing purely vertical displacements and one representing purely east-west displacements (the subject of this metadata). EGMS Ortho simplifies interpretation for non-expert users by removing the need to account for satellite viewing geometry, offering a more intuitive representation of ground motion. EGMS Ortho is visualised as a vector map of measurement points colour-coded by average velocity (vertical or east-west components) and distributed to users in comma-separated values format. Each point is associated with a time series of displacement, i.e. a plot with values of displacement per acquisition of the satellite. EGMS Ortho is delivered to users on an annual basis, following a five-year moving window update strategy. This means that after the Baseline/first update (2016-2021), the following data periods are available: 2018-2022, 2019-2023 and 2020-2024.

In summary, the process follows these four stages: i) identify all the cells with at least one measurement point per orbit, ii) average the time series per orbit, iii) interpolate ascending and descending time series to a common six-day sampling and iv) estimate the vertical and east-west components following equations weighted on the estimated accuracy of the input measurements.
