GPSeismic Version 2007.4 Release Notes Highlights include a new automatic offset method in QuikMap, the support of error elllipse data from systems that provide that information, a new super-fast gridding technique, and a number of GPArc performance and capability enhancements. General 1) You now have the option of using either of two gridding techniques. Gridding is used whenever you create a DEM or contours. Its the process that takes irregularly spaced points and creates a uniformly spaced grid of points. Up to this release, the method of gridding has been triangulation. The technique which has been added uses a distance weighting approach and is called 'proximity'. This new technique is approximately twenty times faster than triangulation and is the default technique in release 2007.4. Other than speed, the biggest difference between the two is that triangulation will compute all data between points regardless of the distance that separates them. Proximity will compute data near points but will not stretch the process to create data between points with a large distance between them. Because of the addition of this gridding method, any options to create a DEM or create contours using Surfer has been removed from GPSeismic. Note - To change techniques, start Project Manager and select the second checkbox under options. 2) You can now elect to add three error ellipse fields to the project database when a new project is created. When available from the raw data, QuikView will populate these fields with the semi-major and semi-minor axis dimensions of each ellipse along with the major axis azimuth. In GPSQL you can now elect to send error ellipse information for display in QuikMap. This was requested by Glyn Barnes of WesternGeco. 3) You can now clear the list of points displayed in the Cogo utility as a result of the user right clicking on points. Affects QuikMap, QuikView and QuikLoad. The 'Clear point list' item is located in the File menu of the Cogo dialog. This was requested by Brian Marsh. 4) Serial Comms support has been extended to 16 ports. This new functionality is available in QuikLoad, QuikView, GPNav and GPLocator. 5) The Multiple Map utility was modified in the following ways: a - now includes the ability to create SHP circular polygons. The user must specify the radius of the polygon. Associated with this is the fact that circular polygons no longer include a small circle at the center. Previously, a 1 map unit center circle was drawn. b - Also added a confirmation message to selection of another applications settings. That is, if you have started the application from GPSQL and elect to use GPArc's settings from the Preferences menu, you are first prompted with the fact that all current settings will be erased. c - When you open or save a parameter file, the title bar will display the name. Every time you open or save a parameter file, a list at the top right of the dialog will be updated. Up to 10 will be listed. Double clicking on any one will instantly display the 'file open' dialog initialized with the current name of the file. This 'most recently used list' is available no matter what application starts the utility. d - If you use the 'Lucky' button to automatically create 8 map layers, you are now asked if you want to create GPArc style files for each layer. If you say yes, you are prompted for a folder. If you do this, note item 11 of GPArc enhancements below. GPArc can now retrieve all styles for a folder. This means that you can now jumpstart your mapping capabilities. e - Finally, rearranged the interface so the dialog is sizeable and the status of file writings can be viewed in its entirety. The user interface now makes all controls for a particular selection (DXF or SHP) invisible so the user has fewer controls staring at him at any one time. These changes were made in response to several requests from Justin Brown of Maverick Surveys. 6) Added column headers as the first record of any CSV made from the modern spreadsheet. 7) Increased custom report builder from 20 to 60 columns maximum. Items 6 and 7 were requested by Tony Maultsby of Conoco Phillips QuikView 1) Added support for MapTech MXF files. This is a separate File menu item on the Generic ASCII Import dialog. There is no configuration necessary for this type of file. Simply select the file for import using the 'Import MXF FIle...' menu item. The file description can be obtained at the www.matech.com website. Note that all double quotes are removed from fields during import. Color and code are placed in the receiver serial number and type fields. This was requested by Justin Brown of Maverick Surveys 2) When available from the raw data, QuikView will now populate three error ellipse fields in the project database. These three fields represent the semi-major and semi-minor axes of each ellipse along with the major axis azimuth. 3) With the addition of proximity gridding (see #1 General topic), QuikView no longer uses Surfer to generate contours via the Charts page of the Reports dialog. Now, pressing the Contours button will create a shape contour map which will be immediately loaded under your data. QuikMap 1) A new automatic offset technique has been added. Survey companies are often provided rules by which a point is to be offset. For example, if a point must be offset, the first acceptable location might be 100 meters (or feet) offline and 0 meters inline. Failing that the point is to be offset 200 meters offline and 0 meters inline. These rules could continue for a number of possible offset locations. In fact, some rules sent to our offices showed several dozen possible locations. The offset guidelines we saw were laid out graphically somewhat like the numbers on a bingo card and thus the name 'bingo card' automatic offset routine. With the requirements above in mind, QuikMap was modified to include this method. The additions include a graphic tool to allow the user to create a small template file which is used by the automatic offset process. You can take a look at this automatic offset method in action at: http://www.gpseismic.com/bingo.htm This was suggested by Steve Overmeer of Wolf Survey & Mapping. 2) You can now elect to send error ellipse information for display in QuikMap from GPSQL. The ellipse layer is a DXF layer in QuikMap which can be saved as a DXF or SHP file. See item 2 of GPSQL for more information. 3) Fixed a problem where appending addbacks to initial layer after performing the compare offsets operation would cause a crash. Thanks to Kevin Pomaski of CGGVeritas for spotting this. 4) Exclusion zone holes are now rendered with transparency. This was requested by Steve Overmeer of Wolf Survey & Mapping. QuikLoad 1) You can now create Garmin WPT (aka PCX5) files from the Utility menu. This was requested by Travis Cundiff or Erickson Contract Surveying, Inc. 2) When creating Trimble DC files, special characters like slashes are removed from the Job name as these could cause a "The system cannot find the path specified." error in the Trimble program, Data Transfer. This was suggested by Cliff Wittig. 3) Added an option to create Lowrance USR files in a special batch mode where each file will contain as many complete lines as possible but not exceed a user specified number of points. This was requested by Aaron Totten of CGGVeritas GPSQL 1) Added an option on the Updates dialog so that you could insert the delimited item of one field into another. For example, suppose you had a NMEA depth record in a field of one of your tables. You could use this to extract the actual depth value of the NMEA record and place it in another field for use. This was requested by Travis Cundiff or Erickson Contract Surveying, Inc. 2) You can now elect to send error ellipse information for display in QuikMap. When the field selection dialog is displayed, a new option is available in which you opt to send ellipse information using an entered multiplier. The multiplier is used in determining the size of the ellipse. For example, if you enter 1000, an ellipse with a semi-major axis of 0.5 will be displayed as one with a semi-major axis of 500 map units. There is also the ability to specify the color and whether to create a hatched, filled or hollow ellipse. The ellipse layer is a DXF layer in QuikMap which can be saved as a DXF or SHP file. 3) For Sercel vibe data import, you are now prompted for the full year on the preliminary dialog. Also fixed a problem in which the survey time field would display date one day greater than the actual Julian Day that was imported. This was spotted by Brian Marsh 4) The default link query specified prior to launching the Duplicate Manager is now remembered. GPArc Note that to use this version of GPArc, it is necessary to be using ArcGis Engine 9.2 Service Pack 4. 1) Added another line renderer which refers to a gallery of over 80 styles. These styles are essentially combinations of two or more line renderers that provide a certain look. For example, some styles provide a simple line with borders while some provide lines with hashing that resemble railroads. There are two areas of concern. The first is that as composite line styles, they render slower, however 90% of the styles are almost as quick as simple line rendering. For the worse styles, a special message is issued confirming their use. The second item is that a few styles don't necessarily look like what the style does in the selector control, most notably, 'high occupancy lane' and similar styles. However, as with the slow rendering styles, this is a small percentage of the styles available. 2) Added left, center and right justification options to the legend builder. Also added ability to select any legend symbol or text for more precise positioning and sizing. Finally, the legend is now a registered PNG file rather than a JPG. The PNG is clearer and smaller in size. 3) Added ability to specify line labels in three different ways. One per name, one per shape and one per part. For example, if you had created a SHP line with one line between each pair of points and specified one label per shape, then you will have exactly that, however, if you specify one label per name and the name in the underlying database is always the same (say 'pipeline') then you only get one label along the entire length of the line despite the fact that its made of many individual line shapes. 4) Added code to map opening routine that appears to speed up that process greatly. Also added an option on the Miscellaneous settings dialog that allows user to load the bottom layer last. Normally, a map consisting of a large image will have that image set as the bottom layer. When a map file is saved and then re-opened, the last layer is loaded first, then the next layer is loaded and placed on top of the first layer and so on. However, if the bottom layer is a large image, as each layer is loaded and the map redrawn, the time taken to do so is great. By checking the new option, all layers except the bottom layer are loaded. Then the bottom layer is loaded and then placed at the bottom of all the other. In this manner, the redrawing time during map loading is reduced. Bottom line is that if you have a large image as your bottom layer, and your map opens slowly, you might want to try this option. 5) The Close Map File menu item was accidentally hidden in Version 2007.3. I have placed it back in the File menu. 6) When you are defining what is to be labeled, if you try to specify an SQL expression for a string field that involves the MOD operator, you are warned that this type of expression requires a numeric field. The same warning is given if you are inappropriately trying to assign a string expression for a numeric field. Note that if you manually write an expression that is inappropriate for the field type, you will notice labels for all layers disappear. 7) Reworked the 'add all layers in a folder' routine. All layers are now added approximately 20 time faster than before. Used a combination of map draw and layer draw suppression to realize the gain. 8) Added the ability to dictate the size and color of the halos that surround text and symbols that you draw on the map. Also, if you look closely at the toolbar, to the right of the binocular icon, you will see that there is now an icon that looks like a black pointer (also circled in attached graphic). When you select this, you are now able to draw a stretchy box around multiple text elements and drag them around, or do the same with a single text element. There is no need to hold down the shift when using this tool. You can also delete the selected text elements using this tool but there is no prompt if you use the delete key so be careful. Note that to edit selected text and all text in the current view, you need to use the 'Edit' menu selection items as before. 9) Added the ability to add halos to normal layer labels. Color and size can be specified. We want to thank Jon Wright with Exterra Surveys for working with us to implement items 3 through 9. 10) Modified point, line and text/symbol dialogs so that all possible font characters appear in a list box rather than a single selection combo box. This allows the user to view a number of characters at one time rather than just one. Also modified these dialogs so that if you are selecting font characters, the appropriate controls are accordingly enabled or disabled. 11) The text/symbol drawing and editing menu items have been reduced in number. Specifically, the 'move single selected text' item is gone. The user should use the selection tool in the tool bar. This selection tool allows the user to simply drag a text or symbol element where they want. It is also used to select a number of elements at one time by drawing a stretchy box around them. 12) When saving a map file, the units are now included in the file and utilized when opened. 13) There is now a 'Retrieve All Styles' Layer menu item. When selected, you are prompted for a folder. All styles files that have the same name as a layer and whose layer type is the same (i.e., line, point, polygon,...) are assigned. This can be used effectively if you are consistent in your layer naming between projects. Items 10 - 13 were suggested by Justin Brown of Maverick Surveys. GPNav 1) Added an option to keep the vehicle in the center of the map, that is, the map moves around the map-centered vehicle. 2) The script button on the Log Settings dialog was accidentally disabled. This has been fixed. 3) Added a button in the toolbar and in the Target menu that instantly toggles the sign of the logging increment. 4) In 'Auto' and 'Zero InLine' log modes, there is an option at the bottom of the Log Settings dialog to go through the all of the mechanics of logging but not to actually log. However, GPNav would still prompt you for a log file. This has been changed so that if you are in one of these log modes and have elected not to log, when you press the log button, it simply confirms that you want to initiate the log mode with no actual file logging. Items 1-4 were requested by Jan Quaak of CggVeritas GPLocator 1) Added a Layer menu item called 'Make Point Layer From ASCII File'. When selected, you are prompted for a coordinate file to input, a filename for the point SHP file to create, and finally presented with the standard ASCII Import Specifications dialog so that you may configure for the specific format of the input file. A point SHP file is created and added to the map display. Project Manager 1) Added ability to specify the default folder for QuikLoad, QuikView and QuikMap when creating a new project. You will also notice the first dialog of creating a new project has been redesigned to show all field adding capabilities. QuikCon 1) Added a 'Save DCO' tool button to the DCO Editor. The existing 'Save' tool button always prompts for saving the same or new DCO. The new tool button saves the edited DCO without prompt. After saving, the tool button becomes disabled and it becomes enabled again after an edit in the editor. The existing tool buttons have been given new icons but operate as before. Make sure you hover the cursor over the tool button to display its tooltip. This was requested by Jan Quaak of CggVeritas.
