Abstract: The Earth Deformation Section of the New Zealand Geological Survey (NZGS) is involved in the analysis of geodetic data to monitor earth deformation. The data used include existing survey control data and that collected from networks designed to monitor geological structures such as active faults and volcanoes. To facilitate the safe storage and efficient handling of data a geodetic database has been established on the NZGS VAX computer system. The database comprises a definition of the formats in which data are to be stored, and software to process the data as well as the data themselves. The data is stored on computer files which can be classified in two ways. Firstly they may be divided according to the network and the survey from which the data arise. Secondly they can be divided according to the data type (such as distance or horizontal angle data types) and then subdivided according to the specific storage format. Different formats are required for each data type to allow for variations in instrumentation or observational procedures used to acquire the data. The software is broadly divided into two groups. Firstly there are programs to create and modify individual data files, and secondly there are programs which use data from several data files for deformation analyses. The data files are designed so that the analysis programs can use any file of a given data type without regard to the specific format of the data
