Apollo PROJECT is a web server application for convenient retrieval of time series data sets from NanometricsTaurus recorders and Store files. It provides options for the user to define complex, re-usable data retrieval tasks, which, when executed, result in the download of complete data sets ready for processing and archive. Apollo PROJECT fully automates this often repetitive and time consuming task, tracking data download progress and building network data files in the format selected by the user. There is no more convenient way to manage large data sets across multiple Taurus units. Benefits ➤ Avoids errors associated with manual downloads,measuring success and reporting completion status ➤ Outputs data directly in the format of choice avoiding additional steps in data handling ➤ Supports multiple concurrent data download projects for efficient data handling and faster turn around times in portable experiments ➤ Removes the tedium from downloading large data sets from multiple instruments Apollo PROJECT: A new conc Designed to meet your data objectives Convenient data access and instrument discovery Apollo PROJECT permits the user to configure complex data recovery projects, each aimed at capturing a specific data set from multiple Taurus or Store files. Projects are defined for a single data request or an ongoing data request, such as constructing a data archive or backup. Defining a number of projects and running them concurrently can greatly simplify data handling, improving turn-around times in portable experiments. Apollo PROJECT accesses data directly over a network from one or more Tauruses, from directories on a network drive or from specific Store files. In portable field experiments, users have the option of copying data from the Taurus media into a network directory or simply connecting each Taurus to the central LAN network. ➤ Archive projects An archive project provides a convenient and simple way to create a continuous data set from multiple Taurus instruments or Store files. A typical project definition includes the list of channels to archive, the archive interval or file length and destination directory structure. Archive projects can be run repetitively without user intervention, archiving the selected data set. ➤ One-time projects A one-time project is a simple and convenient way to download a specific time segment from multiple Taurus units or Store files. ➤ Triggered data A Trigger project automates the task of creating network wide data files from a single list of trigger times. Each of the resulting files contains all data channels for a particular trigger time along with a user defined pre and post event period. ➤ Controlled source A Controlled Source project is used to create combined SEGY files with the correct trace order for individual shot or blast times. When downloading data over a network, the discovery feature automatically notifies Apollo PROJECT of the presence of available Taurus instruments. This greatly simplifies connection issues as users are no longer required to enter IP addresses. Download tracking and data organization Today’s digital networks and portable systems are capable of acquiring huge volumes of high quality data that must be organized into usable data sets for processing and long term archive. Apollo PROJECT simplifies these tasks, organizing the data into user defined data directories and tracking and reporting on the completeness of the data requested. For each project definition, Apollo PROJECT determines what data it expects and continuously updates the user on the progress of the project. When a project is completed, users can be confident that all data has been downloaded, converted to the format of choice and stored in files according to each user’s requirements. cept in data management Familiar web browser interface No special software is required to configure a project definition or monitor progress. Any web browser can be used to connect to the Apollo PROJECT server application. Frequently used projects can be defined, saved and run multiple times or even scheduled to run periodically. Users have the option of running multiple projects in parallel thereby minimizing data download times for efficient field operations. As Apollo PROJECT is a server application, the user need not be continuously connected to the server for projects to run.
