In this work an algorithm of Synthetic Aperture Radar (SAR) data transformation to Hierarchical Data Format 5 (HDF5) is presented. The algorithm consists of the following steps: comparison of metadata and basic radar data within the product structure of the Earth remote sensing system; defining data for recording a SAR image with the identification information, including name, size and address; data conversion according to the specification of the HDF5; recording the attributes and data sets to the target file. An algorithm-based model is developed. The model includes blocks for converting radar data, generating the name and hierarchical structure of the HDF5 file, initializing with basic attributes, SAR image and metadata recording. Modeling was performed for metadata and focused radar image transformation to HDF5 using the MatLab package. After that a specialized software tool Next ESA SAR Toolbox 5.1 was used for image processing. The obtained results confirm correctness of metadata and SAR image recording in the HDF5 format.
Keywords: remote sensing, radar image, data format, HDF5
