##AlTiS : software is a radar altimetry data visualisation and processing software developed to create time-series of water levels over inland water bodies (e.g., lakes, reservoirs, rivers, floodplains and wetlands). AlTiS is software developed by CTOH as part of its activities as a National Observation Service. AlTiS is free software, and it is released as open source under the CeCill License, and is available for download free of charge. AlTiS is working under python3 environment (Anaconda distribution) and tested for GNU/Linux, Windows (10 and next). The AlTiS 1.4 (2020/11) has now identifier IDDN.FR.010.0121234.000.R.X.2020.041.30000 ###AlTiS software is developed for: - **Research** : Analysis tool allowing altimetry data studies over small area like rivers, lakes, flood areas in order to create water time series. - **Training** : Education tools to manipulate radar altimetry data and evaluate their potential to monitor water bodies. ###Download AlTiS AlTiS software available on [GitLab](https://gitlab.com/ctoh/altis) repository. ###Altimetric data working under AlTiS Software AlTiS accepts CTOH altimetry products (Level 2 GDR supplied by the CTOH). CTOH GDR data are specifically conditioned for optimized the data size by making a geographical selection and includes the right altimetry parameters for hydrological studies. The altimetry products available for AlTiS processing are the [following](https://gitlab.com/ctoh/altis/-/blob/main/README.md?ref_type=heads#altimetric-data). **To get altimetry products, you have to be logged on the CTOH Catalog and you will find into the *Download Tab* the request form.**
