Vista Data Vision Data management Publishing

& VisualizationProfessional

IntroductionVista Data Vision (VDV) is an “all included” data management and visualization application for storing and handling data from dataloggers and other field devices. VDV includes the well known data base MySQL now owned by Oracle which is capable of storing data from any number of dataloggers for any length of time. VDV has been developed since 1991. Current version is VDV2011.

Key featuresVDV offers storage of data, visualization by graphs, real-time monitoring and data tables, multiple alarm triggers, creation of calculated sensors, fast processing, configurable security access levels, automatic reports and comprehensive web service for projects of any size.

Operators of VDVTypical VDV operators include Government Institutes like Meteorological Offices, Hydrological Institutes and Environmental Agencies, operators of data logging equipment like Water Boards, Forrest and Wildfire Management and working in the geotechnical sector.

ScalabilityMost commonly, projects run on VDV include tens or hundreds of dataloggers each connected to 10 or more sensors. It is not uncommon to have data from thousands of sensors stored and handled in VDV.

Organization of VDVVDV consists of three powerful applications, most com-monly run on a single PC. The db.robot.c monitors arrival of new data and loads into VDV’s database, db.data.browser is used to configure graphs and look, and db.web.browser is running the comprehensive web service.

Security and BackupVDV includes a watchdog data which may be used by independent watchdog application to monitor the operation of VDV. Data may be automatically backed up to a remote server. VDV has the capability to process past data when restarted. VDV leaves the original data intact.

Support to broad range of usersVDV’s data handling capability supports all classes of users:

The SCADA-type user who is responsible for the 1. datalogging network in whole, and needs to know about sensors alarm status, battery problems and communication faults.The Supervisor who is responsible for the operation of 2. the data network and data management, and needs to know if the system is working as expected.Researchers and advanced users who use data for 3. their scientific work, forecasts, prognosis and reports.Public data service offering up-to-date but 4. downsized data service.

Collection of DataData is collected by any software designed to collect data from the field equipment. As an example, the Loggernet application is used to collect data from the range of Campbell Scientific dataloggers. VDV will monitor arrival of new data and load the new data into its database.

Manual InputBesides automatic input of data, VDV supports manual input of data, where user via web interface may add his manual sensor readings when available. These manual sensor readings are treated like any other sensor readings and may be plotted and reported.

Type of SensorsVDV can receive data from a large variety of measurement systems and sensors. This includes

Meteorological sensors for wind speed, wind direction, »temperature, humidity, barometric pressure, solar radiation, evaporation, precipitation, soil temperature and soil volumetric water content Hydrological sensors for flow, water level, stage level, »water temperature, conductivity, dissolved oxygen, pH and turbidityAir Quality sensors for NO, NOx, NO2, dust (2.5ppm & »10ppm), CO2, SO2 and H2S; Geotechnical sensors for strain, pressure, displacement, »settlement, tilt and extension.

Data Presentation and Data AnalysisData may be viewed in VDV as Time series, XY-Graphs, Intensity Plots, Histogram, Data Table and “Wind” Rose for any data. Data from several locations may be combined into single overview. The User Interface is powerful and intuitive. Data may also be viewed as tables and graphs on real-time pages suitable to give overview of status from a great number of field station spread over a large geographical area.

Support to data formatsVDV offers native support to data collected from the Campbell Scientific range of dataloggers. VDV also supports data collected from almost any other type of dataloggers, field device or instrument by its VDV File Converter. VDV also offers support to manually-collect-ed readings.

Data ArchiveVDV store the data in original format with the original timestamp in its MySQL database.

Alarm toolkit - Sensor readingsWhen receiving new data VDV compare each sensor reading to the alarm threshold settings for that sensor. If the sensor reading is outside the alarm threshol then VDV generates an alarm notification, including on-screen warning and email message to one or more recipients. The user may acknowledge alarm message via an alarm overview web page and add description as needed.

Alarm toolkit - Data update notificationThis process monitors data arrival from field stations and issue alarm if data is not updating as expected, indicating loss of communications, datalogger fault or system error.

Web PortalVDV’s built-in web portal is a powerful interface to display monitored data in real-time anywhere in the world, controlled by comprehensive user access control. Besides offering visualization of data, VDV’s web service give access to real-time maps, alarm overview and acknowledgement of alarms, maintenance of user groups and more. The web service may be localized and customized based on configuration of VDV’s web service’s usernames and passwords.

Access ControlVDV’s Access Control for web-based users is powerful and flexible. It allows each user to have tailor-made access rights, including access to some or all data, language, logos, access to alarm service, downloads and more. The Access Control allows for creation of the typical three levels of user access:

Guests: Only browsing data from a seleced of field stations »Users: Guests + access to alarms, quick reports, »download of dataAdmin: Users + Creation and maintaining of User »Access, groups and more.

Validation toolkitSometimes a single sensor reading or few consecutive readings include noise or spikes so the sensor reading is clearly out of range. These errors can be cleared out by running a data validation. All changes to data are logged.

Report toolkitThe report toolkit is used to create reports as Microsoft Word documents, including sensor readings in tables with calculated average, minimum and maximum values, as well as associated data like graphs, list of alarms and more. Any number of different reports may be config-ured, and the reports are generated automatically and sent to a group of recipients as emails. Reports may also be generated as text files.

Other ToolkitsVDV offers several toolkits that add value to the data. The toolkits are:

Wind Energy - Comparison of Wind Turbine performance »to Wind Turbine profileGMap - Display of sensor data on Google Map »VDV File Converter - Converting most data into standard »VDV data profile for import to VDVDisplacement Graphs - Used for Geotechnical »Inclinometer Sensors

About VDVVDV is developed by Vista Engineering in Reykjavik, Iceland. VDV has been in use since 1991 and has been upgraded on regular basis. VDV is in widespread use around the world among Government Institutes, Environmental Agencies, Universities, Consultants and Contractors. Besides Meteorological and Hydrological projects, VDV is commonly used in Environmental and Geotechnical projects.

who are we?

SQL QueriesVDV supports SQL queries for retrieval of data for user-specific reports, forecast, prognosis and data handling.

Data DownloadsSensor readings can be downloaded for analysis in other software programs.

Virual VariablesVDV offers creation of new calculated sensors, where the new virtual sensor is calculated using User defined formula with reference to any sensor in the system. This is useful for creating results based on multiple sensors, which are perhaps not all connected to the same datalogger. These new calculated results are calculated on the fly, may be plotted as any other sensor readings, and associated with the VDV alarm service and reports.

Logging of VDV actionsVDV has built-in logging feature of all its handling, including alarms, validation and user modifications.

NotesVDV incorporates Notes, where staff members may write notes about individual field stations or individual sensors and add photographs. This is useful for maintenance purposes, as the maintenance history will become easily accessible to all involved.

Web CamVDV offers support to pictures uploaded from web cams. These pictures may be associated with field stations and data, and when data is viewed as trend lines then corresponding pictures will be on display.

Multiple LanguagesVDV allows for multiple language service for its web interface. Support for English, Spanish and German is built-in. A built-in utility makes it easy to create localized version of the VDV web interface.
