WorldView is a world map graphic user interface (GUI). The application runs on Windows based operating systems, and acts as a client to the SCADA host computer.
- Provides a single world coordinates based graphical view of the system, arranged schematically or geographically as defined by the user.
- Able to accommodate a coordinate space of up to 1 billion by 1 billion world units.
- Graphics based and capable of importing DWG or DXF file formats.
- Can be implemented in a multi-layered structure.
- Can resolve the world map coordinates for Lat/Lon by establishing the latitude and longitude limits of the map.
- Supports an unlimited number of graphical layers which can be de-cluttered either automatically(based on zoom level) or manually by the operator.
- Allows the ability to override the automatic decluttering and manually turn a layer
either on or off regardless of the current zoom level.
- A user-extensible library of ready-to-use symbols, colors and text styles are provided.
- Methods of navigation within the WorldView map.
- The operator is able to specify the number of alarm lines for the unacknowledged alarms to be displayed in alarm banner at the bottom of any display.
- Bitmaps (image file) support. The supported bitmap file types includes GIF, JPG, and BMP.
- For any analog point on the WorldView map, the user is able to select displaying the values of Avg, Min, Max, Min Time, and Max Time for Current and Previous: 15 Min., Hour, Day, and either Week or Month. These values are automatically recorded for all analog points within the system and available for display on the WorldView map.
- The user has the ability to create any number of views within the WorldView map. The views may be accessed via a scrollable list box or via pushbutton (poke points) on the WorldView map. For ease of navigation in the views list box, it is possible to organize the views in a hierarchical system of folders. Both the folders and the views themselves can be preserved when the map is re-imported from an updated DWG/DXF file.
- The user has the ability to operate the WorldView map on substation computing platforms for substation automation application.

- World Map Display. This consists of a high-resolution vector drawing of the owner's system, with the current analog values and status of devices superimposed on the drawing. The map allows the operator to select displayed objects in order to issue or inhibit controls, acknowledge or block alarms, or modify operating parameters (such as limits).
- Alarm Display. This display shows a user-Customizable list of alarms that are in the system. The operator has the ability to acknowledge and/or block alarms and to control the operation of the audible alarm.
- Operator Summary Display. This display shows operations messages that have been logged by the system.
- Tabular Data Display. This display lists each station’s status and analog points. This is an operating display in the sense that from this display, the operator can perform point operations such as control, tag, alarm acknowledge or block, as well as modify operating limits and reset transition counts.
Full Graphics Editor
- A full graphics editor is provided as an integral part of the database and display building tools. Access to the editing capabilities is available at all local and remote consoles is password-protected.
- A copy of the WorldView map and supporting libraries reside on each workstation console, such that when viewed in live mode, only dynamic data such as point values and alarms are retrieved from the host server in order to minimize network traffic and make feasible dial-up connections even with large displays.
- Allows the reservation of the WorldView map and associated resources so that only the user implementing the reservation can edit those resources. If another user attempts to edit a reserved WorldView map, they will be notified that it is reserved and the username and workstation of the user holding the reservation.
- Allows the publishing and updating of the WorldView map and associated resources. When the WorldView map is published or at a user settable time interval, all client workstations are notified that a new WorldView map is available.
- Allows the user to create any number of layers and displays of the WorldView map. The editor allows the user to assign zoom levels to each layer for automatic decluttering. The editor also allows the user to specify an image file for any display that is to be used as a background for the display. The image file formats that can be used for this include JPG, GIF and BMP.
- Contains easy-to-use tools for re-layering, re-coloring and re-styling (text) as well as duplication (copy/cut and paste), stretch and re-size. It includes a Find and Replace function that finds all instances of a text string anywhere on the WorldView map, and allows automatic replacement by another text string.
- Provides topological support. It performs consistency checks between the graphical display and the topology database. Connectivity is dynamically calculated based on topology and current status of breakers and switches, and displayed with user-defined color-coding.
- The Survalent system includes drawing tools as part of a full graphics editor to allow the user to add to and/or modify the drawings that were imported via DWG/DXF file. The editor supports at least 99 undo and redo editing changes.
- Includes an initial ready-to-use set of such libraries. On import of a DWG/DXF file, the colors, text styles and symbols that are contained in the DWG/DXF file are imported into the libraries, where they may be customized or just used as is.
- Provides the capability to display a telemetered or calculated analog value in the form of a numeric string, horizontal or vertical bar graph (the length of a bar graph reflects the value of the analog point), or in an analog gauge. Both numeric strings and bar graphs are color-coded to reflect any violation of alarm limits. Analog gauges have the capability to represent a meter or dial type gauge. The user-definable properties of gauges include: angle start, angle length, dial color, dial direction, label properties, limits properties, major/minor divisions, needle properties, and the radius.
- The WorldView map supports a system of “post-it” notes that allows operators to add and remove note icons on any display. Clicking on a note icon causes a pop-up window to appear to show free-form notes on any topic.The notes can be entered and modified in this window.
- Supports notes that are specific to database points. These notes are accessible from a pushbutton in the point dialog box that appears when the point is selected. When a point has some notes, the pushbutton icon in the dialog box is highlighted.
- Point-specific notes are also accessible from the alarms display. When a point-related alarm is selected, a pushbutton in the tool bar is highlighted if there are notes for the selected point. Clicking on this pushbutton brings up the point’s notes.
- WorldView provides the ability to store and view any data value from the database in a trend graphical format. The system can bring up pixel-resolution trend graphs of historical data. Sample rates as low as 1 second are supported.
- Trend graphs can be displayed in separate windows that can be moved, re-sized and minimized to an icon. The trend graph window includes tools that allow the user to configure and customize the graph display.
- The trend graph window has the ability to plot ten (10) points from the historical database. The trend graph displays can be interactive allowing the operator to quickly adjust the time frame, duration and resolution of the graph.
- In cases where there are more samples in the dataset than can be displayed in the graph window, it is possible to scroll back in time. It is also possible to see the numeric values and time-stamp of the traces at any time position in the graph by manipulating a time cursor inside the trend graph.
- The user is able to display trend comparison graphs from left to right, for at least ten (10) comparison trends. In trend comparison graphs, the time origin at the extreme left of the graph is a fixed time of the day; however it may be a different day for each trend. The purpose of this is to allow the user to observe the build-up of the current day’s trace, e.g. a load curve, against that of other days in the past, typically the days that contained the last week peak or the current month peak, etc. The trend comparison graph has an option to set a start time and day of the week so that the trend graph is automatically launched.
