GPSeismic Version 2007.2 Release Notes Highlights include GPArc's new page layout capabilitieswhich include dragging multiple maps onto the page, QuikMap ability to handle XZO files of any complexity, and both QuikMap and GPSQL's ability to create SHP contour line files. General The angular format, angular precision, and distance precision values are now persistent in the coordinate conversion calculator. This was requested by Pablo Verrazi and Gordon Crook of WesternGeco QuikMap 1) There has been several changes to XZO exclusion zone actions. This includes the combination of several utilities into one dialog called the XZO toolbox. In each case, the user specifies and input XZO file and an output XZO file: Simplify Polygons - This is a new feature. Expanding or contracting complex polygons often leads to spurious edge effects. Spline smoothing can also lead to undesirable results depending upon the vertices' proximities. This routine is aimed at removing some of these undesireable qualities. It is not a panacea for all problems, but will generally improve most polygons. Existing items which have been moved from the Search menu to this dialog include: Combine Polygons, Reduce Rectangles, Round Rectangles, Convert Rectangles, and Convert Circles. 2) There is now a 'Static XZO Import' item. This imports XZO files of any size and complexity. You can delete zones from an XZO file imported in this manner but not add to it. 3) You can now lasso an area via the polygon capture tool and delete all exclusion zones inside or outside the capture polygon. 4) The right-click polygon capture menu now only displays applicable items for the current action. 5) The fold analysis dignostic graphs now have Copy and Save buttons so that the offset distribution, azimuth distribution, and midpoint scatter charts can be easily saved or pasted into reports. This was requested by Lisa D'Ambrosia of Lockhart Geophysical. 6) The automatic offsets parameters now include maximum inline and maximum crossline values. This was requested by Steve Overmeer of Destiny 7) The XZO Manager now allows you to export all vertices to a coordinate file. This was requested by Brian Marsh. 8) You can now specify different symbol sizes for primary, hit, secondary, and addback points. You do this by specifying percentage of what is currently selected as the number of pixels. For example, if you select 50% for hit points and have selected 10 pixels in the dropdown, the hit points will be rendered at 5 pixels. This was requested by Brian Marsh. 9) In the XZO tools dialog, you can now elect to compute the intersections between polygons. This was requested by Scott Van Meter of ConocoPhillips 10)The polygon capture group rotate feature now maintains a list of all points which you have right-clicked on. When the group rotate dialog is shown all those points are presented in a list. Any point name can then be dragged and dropped on either coordinate field to populate them. This was requested by Brian Marsh QuikView 1) Added a 'Export To CSV' capability to the Zupt processing interface. Requested by Jim McCarty of PGS Onshore. 2) Added the ability to insert GPS Week and GPS seconds in week from the edit menu in the Zupt processing interface. This only places the current time in the spreadsheet and was added as a convenience. The same action can be performed using the 'change selected cells to' item in the Edit menu. 3) Added another flavor of the SurvCe RW5 Generic ASCII import. You configure for a SurvCe RW5 file as normal. The new 'convert/import' utility is called 'SurvCe (Nobert)'. It is almost identical to the SurvCe Carlson flavor but uses the 'PN' field for the station and the trailing Code for the Descriptor. Finally, if you understand what I just said, please explain it to me. All I know is we have a happy user out there somewhere. 4)A Miscellaneous/Processing Settings option has been added which allows the currently selected preplot Qld file to be used to automatically create a crooked file and then to have that crooked file selected for inline azimuths. This was requested by Brian Marsh GPSQL 1) The ASCII Import utility was failing to import delimited files in which the delimited items were not in sequence. For example, if you configured a field and said it was the fifth delimited item in each record, it would not be correctly imported unless it was the fifth item in the list of fields to import. This has been fixed. 2) Added the ability to make SHP contours from a query. You are first prompted with the name of the SHP file to create. On the field selection dialog, you need to specify easting, northing and z-field. The latter is typically the height, but remember that you can use any field to represent 'z'. Some interesting plots can be made using precision, dop, etc. On the field selection dialog, you also enter the contour interval. You can leave this at 0 for automatic. The second item entered is the number of grid nodes. This is an important value and requires some explanation. Behind the scenes, the routine must first create a digital elevation model (DEM)) from the points from the query. The evenly spaced DEM is then used to create the contours. The best case scenario is that the points in your query exhibit good spatial separation, that is, the entire area to be contoured is neither narrow (in any direction) or bunched up (e.g., many points in one area and devoid of points in another). The grid node value is used to evenly divide up the spatial extents of your data. For example with a value of 100, the 'behind the scenes' DEM consists of 100 grid nodes in the greatest extents direction (NS or EW) and the lesser extents direction gets proportionately less grid nodes. For example, if the extents of a prospect is 50,000 meters in the east/west direction and 10,000 meters in the north/south direction, and you enter 100 grid nodes, the underlying DEM has 100x20 grid nodes. 3) Added an option to list only the single nearest point when using the 'two query' proximity tests. This could be useful in a situation where you have a query that defines hazard points and you need to find the one nearest survey point to each. In this example, what you would do is to run the 'two query' proximity routine (2D or 3D) and select the hazard points for the first query and survey points for the second. On the small dialog that comes up first that allows you to select the two queries, the first is on the left, the second is on the right. When you get to the field selection dialog, you want to enter a large threshold value and check the 'nearest only' check box which is a new option on this dialog. Note that if there is no point within the threshold then no record is written. This means that you want a fairly large threshold if this option is utilized. One final note. When the first field selection dialog comes up, you might want to replace 'Station (value)' with Station (text) if your hazard points have a distinctive alphanumeric name but values of zero. It will aid in the identification of the hazard. This was requested by Rob Irwin of Bearpaw Surveys. 4) Corrected a problem in which modifying a query with a table join would require you to click on the two tables forming the join, thus populating the field list boxes. You no longer have to do this as it will be done for you automatically. Spotted by Peter Parker. 5) Changed the 'Modifications' menu item, 'Append Table To Table (w/Mapping)' so that it honors any table join (left, right, inner). Note that the join fields are listed on the left side of the dialog automatically as it is loaded. The user selects a table (to append to) on the right side as normal. You also Map as normal. This was requested by Alan Stanton of WesternGeco. 6) When you create a SHP line that is continuous from a query, there is now a check box on the field selection dialog that says 'shortest route'. It is important to understand that this routine starts at one point in the query and returns to that same point. This is also referred to as the 'traveling salesman' problem in which a salesman travels from city to city and returns to the point from which e started. Therefore, it is NOT to be used to find the shortest line from one point on a track to the last point on that track. It can be used successfully for two adjacent tracks where the surveyor is to end up at where he started, or any similar route. This was requested by Steve Overmeer of Destiny Resources. 7) Added ability to specify the table to add the 'IsSurveyed' field to. The de- fault is 'Preplot'. Any other selected table must have a 'Station (Text)' and a 'Station (value)' field. This was requested by Esteban Trujillo of Global Geophysical. 8) Added a prompt for height units when importing Opus files. To facilitate this, the table structure for Opus files was changed to include a 'Units' field. If you need to add this because you already have a table with Opus stations, you will need to add a 16 character string field. So the new table structure is Station, Latitude, Longitude, Height, Units. This was requested by Les Merriam of STI. Project Manager 1) Added ability to add contours to the geoid extents utility. They are rendered in ramp colors and there is now a text box to indicate the range of the geoid values of the model 2) Added a utility to create a line SHP file from a grid definition file. You are prompted for the grid definition file and then the SHP file to create. 3) When modifying geodetic settings for the current project, you can now modify the number of bin digits. QuikCon 1) If you tried to create a QCC file and did not check the box which allows a comment to be attached, then no records were written. This has been fixed. Spotted by Jose Luis Camargo. GPArc 1) From the Layers menu, you can now save and retrieve styles. For example, you might invest a great deal of time in rendering a layer exactly how you want it. You can now select that layer and elect to 'Save Style File' in order to save those parameters to a file. You can open another layer(or map), select a layer and then from the Layer menu, 'Retrieve A Style For The Selected Layer'. This will instantly set all rendering parameters for that layer. This was requested by Justin Brown of Maverick Surveys. 2) Completly revamped the Page Print control. There is now a selection tool that can be used to select the map frame and resize, cut, copy and paste. For example, you could create any number of map depictions on the page so you could cut a number of small maps from one page. When the map frame is selected, it reveals 'handles' for easy moving and resizing. This new method obviated the need for the slide bars. This was requested by Justin Brown of Maverick Surveys. 3) The SHP point import routine generated an error if the number of imported records was extremely large. There is now no restriction. 4) The Multiple Map utility was not writing the query correctly when trying to automatically configure the interface for odd and even tracks.
