Spatial Datalyst has engineered the Viewer using 32 bit technology therefore most Windows OS can be used, however the only operating systems that have been tested are Windows 7, Windows 8, Windows 8.1 and virtual OS on Macs. The size of the databases was a major concern in making this decision. The databases are large but all of them can be viewed, filtered and exported in the 32 bit environment. Additionally, by using 32-bit OS's the product can be used on most of the existing machines in use today.
SDL requires 2 GB of RAM.
Any storage medium can be used as the requirements are quite small.
Yes, SDL Network Viewer allows the user to customize file attributes and allows for exporting to Pipe-Delimited, CSV and KML. Other types may be added in the future but these types address most user needs.
Yes, the user can see every column and every row in the database unlike some data viewers where the data is paged, SDL shows all columns and all rows. This sometimes requires the use of almost 2 Gb to do so but experience has shown that when users can see all of the data it allows for a better user experience. If the number of rows or columns is greater than the screen size can accommodate then vertical and horizontal sliders can be used to see the unshown data.
The following is taken from Wikipedia: Keyhole Markup Language (KML) is an XML notation for expressing geographic annotation and visualization within Internet-based, two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer. It was created by Keyhole, Inc, which was acquired by Google in 2004. KML became an international standard of the Open Geospatial Consortium in 2008. Google Earth was the first program able to view and graphically edit KML files. Other projects such as Marble have also started to develop KML support.
A standard database is one in which the Viewer has knowledge of the Column Structure and data types prior to importing. This applies to almost all of the databases. The SDL Network Viewer goes one step further however and gives the user the option to import a non-standard database which means that the Viewer does not know the column structure and data types. In the case of the latter a Field Mapper must be used to teach the viewer where the appropriate fields are so that proper exporting can be accomplished.
The Roll Your Own filter allows the user to build a filter expression instead of using the manual filter provided. The user can learn how to build the expression by watching the Status Strip of the Filter Palette during a filtering operation. The Status Strip shows the filter expression being used and it can be copied to the Clipboard for future needs. The Filter Expression is Plain Text but must be formatted correctly to be used in the RYO box. The format is easily learned after several filtering operations. The expert user can build a dictionary of frequently used filter expressions and use them instead of the more time-consuming manual process. The RYO option takes precedence over any other selectors that may be in effect at the time.
The RYO capability only allows a single expression but the levels in the expression are essentially unlimited. In other words, the filter expression itself has as many clauses, operators and values that can be imagined.
This is what is known as a nonstandard database or a Generic Database. The Viewer can be used to view any type of plain text CSV file or any Excel file. The Generic Database Importer also allows the user to select an Excel file and then further select which tab within the Excel file to import.
The database can be simple sorted just by clicking the column header. Clicking the column header a second time will reverse the sort order. In some cases however it is preferable to be able to sort on multiple columns. The Customer Sorter feature allows for this.
A Link List database is an industry standard database that conforms to a Path Loss export type. Path Loss is used by many of the Telecom Path Design Specialists and this feature allows for projects that have been previously defined using another tool to be easily imported into the SDL Network Viewer.
The KML Options selectors have been developed so that the user has maximum flexibility over how the data is displayed in a KML file. The Symbology Editor (as it is sometimes called) is extensive to allow for as many as 36 different options for Site-Only databases (no paths). But if Path Databases are used then the path color can also be customized allowing for 216 different choices. The number of options was arbitrary but chosen to allow for even the most extensive customization to be achieved.
There is no industry standard for what the SDL Network Viewer does and that is part of its appeal. But when the tool is used insteadof traditional design methods experience has shown that 60% of the time required to design greenfield networks can be saved by knowing where current users are installed and where the property owners are located. Additionally, since the viewer shows which frequencies are in use it keeps design iterations and possibly even Field Survey efforts to a minimum.
The 3D option in the KML Options page provides a way for the user to see in the KML Export where the Radiation Centers are located on a structure and then drops a 'fence' between structures so the line of the path can be followed in the KML depiction. This is a very powerful option in that it shows potential obstructions or other environmental obstacles that should be considered during the path design process.
There are actually three different database types in the Field Mapper. There are:
Full Paths (Non Half Paths)
Sites-Only databases do not have paths in them. There are two different Sites and Paths databases which SDL refers to as Half Paths and Non Half Paths (or Full Paths). The distinction can be complicated to explain. The difference between the two has to do with the structure of the database itself. Half Paths are databases that display either a Go or Return path per row of the database. In other words, a row in the Half Path database only has one direction of transmission described by the dataset. The Non Half Paths databases describe both the Go and the Return Paths on a single row. While the distinction may seem unnecessary it comes into play when the Site Balloons are selected. In Half Path databases there are only Site A Site Balloon options to select from. In Non Half Paths both the Site A and Site B Balloons have to be selected.
Almost all of the databases that SDL Network Viewer can access are standard databases. This is a good thing because the default options for exporting are preselected and requires no additional user input, although the user can change the defaults if he wants to. Nonstandard databases do not have any preselected options and therefore require the user to specify these selectors in order for the exported file to show the relevant path and site information.
This is a feature of how the FCC designed the database. Clearly the emphasis is on TX sites and in Fixed-Point-to-Point communications every RX site is also a TX site so the geolocation data is in the database but not necessarily where one might think it deserves to be. It is not known why it was done this way.
This is a complex question in that there are two types and Sites and Paths databases. One type has Go/Return data on a per line basis and the other has Go/Return and Return/Go on a per record basis. The Site B data is used when there are both types of paths per record.
See answer to 25 above. An example of a Go/Return-Return/Go database is a link list. An example of a Go/Return database is pretty much anything from the FCC. One is not necessarily better than another except in the area of expectations. Most users probably think that all databases are Go/Return-Return/Go.
