NO, the predictive capability is protected by the licence file and configuration files which are supplied separately to the software.

Is the POLPRED program sold as a single user or is it a site license?
POLPRED is sold either for installation onto a single PC or for network installation. Additional copies of the software plus the same model grid can also be purchased for a smaller charge. One licence file is supplied each time you order a licence, this can then be copied onto all machines that have POLPRED installed. Only one licence file needs to be purchased regardless of how many machines it is used on.

Is model licensed for a site/company?
POLPRED can be installed onto a PC owned by the company at any of their premises. Additional copies of the software can be purchased for installation onto other sites.

How intuitive is the program?
We think the program is easy to use having a simple to use graphical interface (if you are familiar with the usual Microsoft Windows features), it has a complete help system and user manual detailing all the features.

Can the POLPRED program be embedded into other programs, if so is there a different cost?
We have a Dynamic Link Library (DLL) for software developers, which can be incorporated into your own software that requires offshore tidal predictions. We usually operate a royalty based system for the use of the DLL. Contact the Applications Group for more information.

What are the output/export options from POLPRED for both text and graphics? And how configurable are the outputs?
Graphs, plots and maps can all be sent direct to the printer. Text outputs can be stored as ASCII text files. Units of output can be specified (metres, feet, knots) as well as decimal places. Directions are always degrees from North (°True).

What formats (if any) can be imported into POLPRED as overlays to POLPRED graphics, eg platform outlines, pipelines etc?
User specified areas and point locations with labels can be defined by the user in simply formatted text files and plotted as another layer over the maps.

What is the datum used in POLPRED?
The latitude/longitude co-ordinates used in POLPRED are geographic co-ordinates and not geodetic (eg Not ED50, WGS84 etc). The reference datum is either an 'undisturbed sea surface parallel to the geoid' which we approximate to Mean Sea Level or Lowest Astronomical Tide (LAT).
