Security Key Network Compatibility

The security keys we now use are network compatible. This implies that a user is not required to have the security attached to his computer and can access a key (license) across a local network and even via terminal services. Please note however that each security key tracks its use and ensures that only one user can access it at a time. So, multiple users can access the same security key the only restriction is that one user must finish using GPSeismic with the key before another will be granted access to it.

Each key has a hard limit of one license; however, we do have clients with multiple licenses (keys) who place all of their keys on a single server. Their office staff with local IPs and remote staff via terminal services regularly access licenses (as long as one is available) from the server.

License Restrictions

1) For local users where the key is connected directly to the workstation or where the key is accessed from a server via a local area network, each license (key) allows multiple instances of any combination of the GPSeismic applications for the same user. Regardless of which applications are running, this user would consume one license.

2) For remote users via terminal services, a single instance of any GPSeismic application will consume one license (key).

Software Installation

Note that GPSeismic does not need to be installed on the server. The software that must be installed on the server is the security key driver and server software. This installer is available as a single executable which can be downloaded from our FTP site via:

ftp://ftp.gpseismic.com/security/

Download and run the sole file in this folder (Sentinel_Keys_Protection_Installer.exe) on the server. Once this is complete, you can then attach as many GPSeismic USB security keys to the server as you like. Then on each workstation which has GPSeismic installed, you will need to modify a small XML file in the GPSeismic installation folder (typically C:\Program Files\GPSeismic) called sntlconfig.xml. In this file, between the ContactServer tags you will need to replace localhost with the local IP address of your server. This will tell that installation of GPSeismic to look for a key (license) on the system with the entered IP address.

GPArc Installation

GPSeismic requirements -You should first download and install GPSeismic software. If you have not done that already, go to the download page now.

ESRI library requirements - Once GPSeismic has been installed, you must install ESRI's 'ArcGis Engine Runtime 9.2' for Windows. If you currently have ArcView, ArcEditor or ArcInfo 9.2 installed on your system, neither this step nor any steps below are necessary (except for Service Packs) and you should be able to start using GPArc immediately. If not, download the ArcGis Engine and install. You should choose the 'typical' installation and follow all the prompts. For trouble-free operation, you should be using the Service Pack that GPArc was compiled with. For GPArc 2008.0 and later, that is Service Pack 5.

You need to purchase the ESRI runtime license by contacting your regional ESRI office. At the time of this writing, the cost was 500 US. You can use ESRI's regional US office page or international page to help assist you in finding a contact number. Again, make it clear that you want to purchase the 'ArcGis Engine Runtime' 9.2 libraries for Windows. Once you purchase the 'ArcGis Engine Runtime', you will be sent an authorization number with the format 'ECPn' where 'n' represents a nine digit number. Once the ArcGis Runtime libraries are installed and you have your authorization number, run a program called 'SoftwareAuthorization.exe' located in the '/ArcGis/bin/' folder. The Software Authorization program will assist you in obtaining an authorization code that allows you to register the software on your system. Once the ESRI libraries are registered, GPArc should run.

Vibe System Support

Formats supported - GPSQL can import Pelton, Sercel and Tigenav vibe data, either in batch or a file at a time. The resulting field structure of the table of the imported data is the same as the Postplot table for the first dozen fields.

Computing the COG - GPSQL creates and/or appends a table with records consisting of the position average of all records for each station in the vibe data table. The table contains the averaged coordinates and values which indicate how many points went into deriving the average and the RMS of the individual distances from each point to the resulting COG. If desired, averaging can be accomplished by first averaging the individual coordinates of each vibe and then averaging those to finally compute the COG.

GPSQL/QuikMap connection - With the parent and averaged table discussed above, you are in a good position to look at the vibe data visually. You do this by writing queries that represent the imported vibe data and the averaged data Select the imported vibe data query as the first layer and the averaged data query as the second layer and send this to QuikMap using the two layer utility. Once the data is displayed, go to the File menu and select 'Compare/Offsets'. Zoom in and prepare to be enlightened.

When you compare points as above, if there are multiple matches, QuikMap can construct a special DXF layer which is comprised of pointers to duplicate groups that fail to meet some user criteria. Click the pointer and a text box shows what the problem is.

GPSQL Duplicate Manager - There is a utility in GPSQL for managing duplicates. This utility can be used to isolate duplicates in a query and see just the points that make up each duplicate group along with a computed center of gravity (COG). It is also possible to see a point with the same station name from another query as well as a template of intended relative vibe locations. It is possible to delete, modify or add points.

Summary Of Vibe Data Processing Tools

1) import utilities for Pelton, Sercel and TigerNav in GPSQL 2) ability to create table of averaged data in GPSQL
3) ability of QuikMap to add template overlays
4) ability of QuikMap to add diagnostic DXF layer for multiple comparisons
5) duplicate managing utility in GPSQL

Canadian users have the ability to purchase an option From Dynamic Survey Solutions which provides access to the Alberta and Saskatchewan Dominion Land Survey (DLS) systems, as well as the British Columbia Petroleum and National Gas grid system (PNG). The DLS/PNG township option for GPSeismic allows the user to determine from within various applications which section/unit a point is contained in or which corner a point is nearest to. Also, maps can be created for any region which depict the sections/units, and where applicable, road allowance and legal divisions.After purchasing the DLS/PNG option from Dynamic Survey Solutions, you must obtain the desired data for Alberta, Saskatchewan or BC. For Alberta, the data is free from AltaLis:
