Program to convert tds raw to maptech field file

This scale factor is calculated as the average of the scale factors at the occupied and foresights points. In order to calculate the state plane scale factors, the traverse coordinates must be in state plane coordinates. When this option is selected, the program will prompt for the state plane zone to use.

Select either Zone 27 or Typically this adjustment is small and adjusts the elevation more than the horizontal. This reference closing point is used to calculate the closure. If you do not specify this option the command will use the starting coordinate as the reference closing point. After you select OK for the first dialog box, the Traverse Points dialog box appears. Enter the starting and ending point numbers.

The command reads the raw file to set the defaults for these point numbers, which are used to calculate the closure. The difference between the ending point and the reference closing point is the closure error. The sum of the traverse distances from the starting to the ending point is used as the total distance traversed. After you pick OK for the second dialog box, the program starts processing the raw file from the top record down. The result is displayed in the standard report viewer, which you can use to save, print, or draw the report.

Stadia Processing Method: Processes Stadia surveying notes. Stadia sighting depends on two horizontal cross-hairs, known as stadia hairs, within the telescope. These hairs are parallel to the horizontal cross-hair and are equally spaced above and below it. The distance between the two stadia hairs is known as the intercept.

The distance from the instrument to the rod is times the intercept. For example, an intercept of 3. For entering in stadia notes, you would enter the horizontal angle, the distance entered as the intercept X and the vertical angle.

This process command applies an angle balance to the traverse lines when calculating the coordinates. This command displays the same dialog box as No Adjust. The angle balance takes the angular error divided by the number of traverse lines and adjusts the angle of each traverse line by that amount.

The angular error is the difference between the angle balance shot and a reference angle. If no AB record is found in the raw file, then the command prompts for which traverse shot to use as the angle balance shot. The angle from the angle balance shot is calculated as the angle from the occupied point to the foresight point. The reference angle can be specified as a bearing, as an azimuth, or by two point numbers in the dialog box shown.

The angle balance report shows the unadjusted points, the unadjusted closure, the angular error, the adjusted points, and the adjusted closure. Typically, but not always, applying the angle balance correction improves the traverse closure. These process commands apply the selected rule of Compass, Crandall, or Transit, to the traverse lines when calculating the coordinates.

The dialog box is the same for all three methods. The reference closing point is used to calculate the closure.

After the command adjusts the traverse, it also recalculates the sideshots. The closure error is calculated as the difference between the closing shot and a reference point. If no CL record is found in the raw file, then the command prompts for which traverse shot to use as the closing shot. The foresight point is used as the closing coordinate. The reference point can be specified by point number or by entering the northing, easting, and elevation.

The process results report shows the unadjusted points, closure error, adjustments to each traverse point, and adjusted points. From the raw file data, this command makes initial calculations for the coordinate points in the traverse. This data, along with the control point coordinates and angle and distance measurements, is stored to a data file with the same name as the current RW5 file using a. LSQ extension for example, survey. The constraints of the command are:. The coordinates of the starting and the ending points must be known.

The command begins with a dialog box where you specify the reference closing coordinates and any scale factors to apply to the distance measurements. The Reference Closing Point is the last point in the traverse, whose coordinates must be known.

If an angle balance shot is used in the traverse, the Reference Angle Balance Angle must also be specified, either as a value or as the angle between known points. Since angles and distances have errors of different magnitudes, they are normalized using weights, based on the accuracy and confidence with which these quantities have been measured.

Below is the dialog box for specifying the estimated measurement errors. For example, for a "5-second" instrument, this error would be 5. The command calculates the weights for each distance and angle measurement using these measurement errors. The control points, points to adjust, distance, and angle measurements with weights are reported. This command edits the points, measurements, and weights stored in the. LSQ file associated with the current RW5 file, using the dialog box shown.

You can edit, add, or remove the control points. You can also adjust points, angle measurements, or distance measurements. The command does not check that the editing is valid, so you need to make sure that you keep a good set of least-squares data and don't delete a needed control point.

The first two, Control and Adjust Points use the first Edit Point dialog box, the other two observation settings have their own. This command applies a least-squares adjustment to the data stored in the. LSQ file associated with the current.

After the adjustment, the rest of the raw file is processed to recalculate the sideshots. You can choose to draw standard error ellipses around the adjusted points. The ellipse axes are multiplied by Ellipse Scale Factor to make the ellipse larger for easier viewing. The least-squares process report shows the input data and the results. For each point, the amount adjusted and the standard error in X and Y are reported. The Reference Standard Deviation is based on the sum of the residuals and the initial estimated standard errors.

The Chi-Squares test is a goodness-of-fit test that checks the reference standard deviation with the least squares model. If this test fails, there may be a blunder in the measurement data or the initial estimated standard errors were too low or too high.

The following is a sample Least Squares Data report. The Tools menu of the Raw Editor contains commands to help you manage points and angles in the raw file. The residuals are the difference between the measurement and the final average. Has anyone else felt this pain? Message 2 of The software itself is free.

Regards Laurie Comerford ctbailey bailey-associates. Message 3 of We've been commenting out these errant CONT lines for years, but we can't take it anymore. Message 4 of Craig, Wow, was just getting ready to post this. Is this what is happening to you? At point the line should end and thru are just single shots, but stringer is placing a CONT PW before point Are we ending or coding wrong?

Jeff Jeff Civil 3D Preview file. Message 5 of Each method has its pluses, minuses, and work arounds. I can only hope things will change for the better As for the continue command, think of it as this: A Begin command is a Pen Down command.

The End command is Pen Up. If a Figure is continued, for example a top of curb is continued after a hydrant is shot, the Continue command puts the Pen Down drawing from the last Pen Up. Message 6 of I'm sure this will help NOT! I do it all of the time from either the onboard exporters or Leica X-Change. In all seriousness though, I do hope you find a solution.

All of these instrument companies are going the "use our tools and nothing else" idea. I feel Carlson will dwindle into nothing in terms of data collection, communication and the drivers one day because of this. A fellow surveyor friend of mine is having issues with Carlson and a Topcon robot. Needless to say he's being talked into buying all Topcon because it works better, just as Leica to Leica does.

Again, companies like Carlson will suffer from this. At least TDS is owned by Trimble. So if you have Trimble you're in luck I guess. Sorry to rant on but this does relate to problems with interelating RAW data output into your favorite flavor from whatever hardware. Good Luck, Mark Driver. Message 7 of You hit it right on the head when you said "SDR coding. And, like you show, when connecting shots that should be in the same figure, the descriptions must match.

Your example if running the top of curb, and the jumping to a hydrant and then back to the top curb is perfect. Basically, when the conversion software converts a reduced-to-coordinates "raw file" it must slip the "BEG, "CONT", and "END" commands in as line notes prior or after the shots are taken.

But here's the problem: The TDS boys programed their conversion software to automatically slip in that "CONT" command when the crew cheif goes back to a previously used shot description.

But - if the crew chief is running the Data Collector and is adding the linework commands to the RAW stack as note lines instead of incorporating them into the shots, then the conversion software should not add those "CONT" commands, because the chief will add those in manually. In other words TDS, and it appears stringer connect, should be able to decide which method the crew chief is collecting data: A Commands-in-shots or B Commands-as-notes The conversion software shouldn't use both methods in creating the FBK.

But I would graciously and humbly accept a patch to their ForesightDXM that corrects this minor flaw. I still haven't seen stringer connect personally, but I hope they email me a copy so that I can test it here.

One week ago, one of the partitions suddenly turned into RAW format. While I cannot access any data stored in it. So you might wonder why that happens? Usually, there are 4 main reasons. The partition table of the drive is corrupted due to virus and malware attack, or the MBR of this hard drive is damaged.
