COORDINATES MENU

DELETE

First point #, Last point #
Enter the point numbers of the first and last points to be deleted. When points are deleted, the file size (# records) remains as is. Therefore, the last point number may not be the actual last point, but will be the maximum number of points that the file once contained.

LIST or LIST UNUSED

First point #, Last point #
Enter the point numbers of the first and last points to be listed. These fields will appear with default values for listing the entire file, and may be edited. The desired points are listed to the screen, and you can scroll both vertically and horizontally to view all the data. To edit the coordinates or description for a point, double tap on the point. Press the X in the corner when done.

ENTER

A coordinate point requires a point number, a northing and an easting. Elevations and descriptions are optional.
Enter coordinates screen

Pt:
Enter the point number of the coordinates to be entered or edited. If the point already exists, its current values are displayed. If the point is numbered higher than the current highest point number, the program will ask if you wish to extend the file to include the new point.

N:, E:
Enter a northing and easting for the point. A point with northing and easting of zero is an unassigned point.

H:
Enter an elevation for the point. An elevation of -9999 is considered to be unassigned.

De:
Enter up to 20 characters to describe the point (any characters, including spaces).

Press Store to store the point and the cursor returns to the “Pt:” field and displays the next sequential point number. Enter another point or press the Menu key to return to the main menu. Press the Assume button to use coordinates of 10000, 10000. This is useful when starting a job where you have no coordinates established yet.

MOVE

The Move option moves points from another coordinate file to the current file. The points are not deleted from their old location.

Move from file:
Select the file from which the points will be moved. If the file does not exist, a message will indicate that the file cannot be opened.

First point #, Last point #
Enter the point numbers of the first and last points to be moved.

Re-number as Point #
Enter the point number in the current file where the first of the relocated points will be moved to.

– If a point is already used, and point protect is on, the program will ask if you wish to write over it: Press Yes or No, accordingly. If No is selected, the program will request a different point number.

– If the point number is outside the file, the program will ask if you wish to extend the file: press Yes or No, accordingly.

DESCRIPTIONS

The program comes with a pre-defined list of about 100 point descriptions, stored in a file called ‘\Program Files\FieldWorks\descr.txt’ You use this function to customize that list of descriptions to suit your type of surveying. For example, you may never encounter a BANYAN TREE, so you could delete that one and add some types of trees you need.

First, press the down arrow on the edit box, then select a description to work with, using the up or down scroll arrows on the edit box, or the wheel on the side of the palm-size PC to scroll up or down the list of stored descriptions. Once one has been selected, it may be modified or deleted.
Enter descriptions screen

Add De
Enter a new description into the edit box, or edit a previous description, then press Add De to add it to the list. If you edit a previous description, it will also exist in the list unedited.

Del De
Select the description to delete, then press Del De.

Store
Stores the changes you have made and returns to the main menu. The list is sorted alphabetically.

Menu
Returns to the main menu without storing your changes.

Import
Imports an entire description list from an ASCII file you have created named \My Documents\mydescr.txt with one description per line. This allows you to import custom description lists easily from other programs. If the first line of your mydescr.txt file is NO SORT (uppercase) the descriptions will not be sorted.

CAD code
Use this button to define how to automatically plot lines, curves and symbols in CAD programs such as PocketCAD or AutoCAD based on the point description. This is used in creating DXF files as well as plot-as-you-go using the Fieldworks addin for PocketCAD on the next page. The selected description is displayed in the top box. The default values are to plot point numbers as block, layer PT, size 10, no line, and no symbol. To change the default settings used for all points with descriptions that have no CADcode assigned, edit the CAD code for a blank description. CAD codes are stored in a file \Program Files\Fieldworks\DeCode.txt
CADcodes screen

Point Numbers as:
Choose how to plot point numbers, elevations, and descriptions, either Text, Block or None. Point Blocks are created in Softdesk format of POINT, ELEV, DESC. We chose this since most software (AutoDesk, Carlson, Microsurvey) has a way to convert these blocks.

Layer:
Choose a layer for points.Size:Enter the size for the point numbers in drawing units (i.e. 10′ at a scale of 1″=100′ will be 0.1 inches high)

Draw:
Choose whether to connect consecutive points with this description with a line (3d), 2d line, or the second and third points of a 3 point arc, or none. The program remembers and draws up to 5 different lines at a time in a first-in-first-out stack.

Layer:
Choose a layer for the line or arc (if used.)

Symbol:
Enter the name of the Symbol (Block) to be drawn at each point. This can be used for things like Tree symbols. For plot-as-you-go with PocketCAD, the block needs to be defined first by creating it or inserting it once into the drawing. The block must be saved in the \My Documents folder.

Size:
Enter the size for the symbol in drawing units (i.e. 10′ at a scale of 1″=100′ will be 0.1 inches high)

Layer:
Choose a layer for the symbol.

Fieldworks Addins for PocketCAD

Included with Fieldworks are custom programs called Addins for PocketCAD to pick points by pointing at them in your CAD drawing, to Plot-as-you-go based on the descriptions, Show your position with an X on the drawing, Center the drawing about your current position, and to bring a Fieldworks Plot by point numbers into a CAD drawing. To use them you must have PocketCAD installed, which is available from XYZworks. This adds the power of an AutoCAD compatible drawing system to view and edit your drawing while still in the field. You can exchange drawings with any system that stores in DWG or DXF format, including Autodesk, Softdesk, Carlson, Eagle point, Maptech and MicroSurvey. The Addins provide some powerful functions which work by having the CAD program and Fieldworks both running and sending messages to each other, and changing from one to the other by a single button press. This is where the multi-tasking advantages of Windows CE become useful, since you can use the full screen for the CAD drawing and another full screen for data entry and review. The first step is from Fieldworks you press the CAD button in Collect, Stakeout, COGO or the Coordinates-Enter screen to switch to the CAD drawing. Then pick one of the Fieldworks addin buttons described below, which activates the link between the programs.
sample CAD drawing

To load an Addin, in PocketCAD hit Tools, Addins… and pick FieldworksAdd. You will probably want to check the box after it has loaded to make it automatically load whenever you open a drawing. (do not do this with FieldworksPlt.) You probably want object snap (the magnet button) set to endpoint of lines and insertion point of text before you use this. It adds 4 buttons to the PocketCAD menu:

1.) Stakeout (XYZworks logo)
Pick stakeout point:
You put the stylus down, and keep it down and you can see the cursor snapping to objects (if you turned on object snap) until you get the one you like, then you lift it and you are back to Fieldworks with Coordinates and staking data. You can also use this in COGO or Coordinates-Enter. To store the picked CAD coordinates in Fieldworks, for example to pick your occupied or backsight points from CAD, first enter an un-used point number where you want to store. When it prompts you for the coordinates, press the get-CAD button to switch to the CAD drawing to pick the point and pop back into Fieldworks. This command keeps running until you pick a different CAD function.

2.) Plot-as-you-go (the button says IN on our logo.)
After pressing this button, it pops over to Fieldworks, and any new points you store in Fieldworks will be plotted in the CAD drawing based on description CADcodes explained on the previous page. Press the CAD button in Fieldworks whenever you want to take a look at the drawing or do any CAD functions such as editing or adding lines or text. You can use this 2 ways: (a) is the default with the Fieldworks screen visible and drawing being done in the background, or a new method (b) with the CAD drawing visible and the Fieldworks screen working in the background (mainly designed for GPS and robots, great for recon with a handheld GPS.) For (b) you hit CAD to return to the drawing and use the Show Position or Zoom centered button so you see an X, then to make it track your position on the drawing use the 1st function key (F1) for Measure and the 3rd key (F3) for Sideshot to store points (and draw lines if used.) While the X is tracking your position, you can use the Pan function if you go off the screen, or many other CAD functions. Many creative options are possible while viewing the drawing, for example set AutoSS to take a shot every 2 seconds, hit F1, and you will see the shots (and lines if used) appear on the drawing in real time. Press the Plot-as-you-go button to switch to Fieldworks to enter descriptions, stop the AutoSS or to see the Status of your instrument. To turn off Plot-as-you-go, press the Stakeout Addin button.

3.) Show position
This button triggers a measurement as if you hit the Measure button, computes your coordinates and then displays an X at your current position on the drawing. Make sure Fieldworks is in either Collect or Stakeout and receiving data from your instrument or this function will not display anything.  It will then track your position if you hit the F1 – Measure function button. You can change the size of the X displayed in PocketCAD using the Tools-Options-Point Size field, if you don’t do this you will only see a dot. You may want to delete the single point entity used for this function before you save the drawing, but don’t delete it sooner or this function will not display anything until you open another drawing. To stop the updating X, press one of the other addin icons.

4.) Zoom centered
This button works like Show position, and then zooms the drawing to be centered about your current location on the drawing. This is useful if you can’t see where you are, or you are off the currently displayed window.

To load the Plot file Addin, in PocketCAD hit Tools, Addins… and pick FieldworksPlt. You should not check the box that loads this one every time you open a drawing. It adds a Plot button to the menu, which prompts you to select a job (FWK) file and a plot (PLT) file. Then it brings the points, lines and curves in the plot file into the CAD drawing. The point# text goes on the PT layer and lines and curves go on layer 0.

TO ASCII

Transfers the current coordinate file to a generic ASCII file with each line containing: Point number, northing, easting, elevation, descriptor separated by commas or spaces. This file can then be read and used by most other surveying and CAD software. If you have Laser Atlanta and the CadZone software, select CadZone in the Options function and you get a ASCII file with special features discussed below.

File name:
Enter a filename to store the ASCII file. The program will add an extension of .ASC if you don’t enter one.

First pt:
Enter the first number of range of points to transfer.

Last pt:
Enter the last of a range of points to transfer.  Press OK and the data will be seperated by commas, or press No commas and the data will be seperated by only spaces.

Laser Atlanta – CadZone special features
There are 3 special commands that you can put into your point descriptions. If a description begins with any of these characters, here is how it is interpreted:
L name, description -This means line space name comma description. If the name is NCURB then it defines a curve.
P name, description -This means polyline space name comma description.
V name, corner point -This means vehicle space name comma corner point which must be either RR, LR, RF or LF to describe which corner of the vehicle, such as V HONDA, RF

FROM ASCII

Reads a file where each line contains point number, northing, easting, elevation, descriptor separated by commas. This lets you bring in coordinate data from most other surveying and CAD software.

From ASCII file:
Select the ASCII file to transfer from. All the points in the ASCII file will be read and stored into the current coordinate file.

ASCII file have elevations? Press Yes or No.

Point protect? Press Yes or No to protect points in the existing file. Note that if you bring points into a file which already contains points and you have point protect on, you may get tired of hitting Yes to overwrite existing points. If you get into this situation, press Cancel to cancel the entire operation.

FLD TO ASCII

Transfers the current field data file to an ASCII text file. The ASCII file is created in SMI, TDS, or generic format, see the Options function. SMI and TDS format take up roughly twice the space as the original FieldWorks format field data file, so make sure you have enough free space in memory for 2x the number of records.

This file may then be sent to your desktop PC using ActiveSynch for further processing, printing and adjustments by most surveying software.

File name: Enter a filename to store the ASCII file. The program will add an extension of .ASC if you don’t enter one.

For generic format, each line contains:
Ref. point, From point, To point, HI, HT, HA, ZA, SD, Point Description.

SMI format (also called SMI Raw Data File) contains:
for each new setup:
From point, N,E,H, Description

then for each shot:
HI, HT, Point Description
Ref. point, From point, To point, Back Azimuth, AR, ZA, SD.

TDS format contains:
for each new setup:
From point, N,E,H, Description
From point, Ref.point, Ref. Bearing
HI, HT

then for each shot:
From point, To point, AR, ZA, SD, Point Description

SDR format is used on the Sokkia and Lietz SDR series and contains:
for each new setup:
02 From point, N,E,H, HI, Description
07 From point, Ref.point, Ref. Bearing
03 HT

then for each shot:
09 From point, To point, SD, ZA, HA, Point Description

ROTATE

Rotate is used to perform one or more of the following functions on a group of point numbers within a coordinate file:
Rotation – make a computed bearing agree with a know bearing.
Translation – add/subtract a value from coordinates and/or elevations.
Scaling – apply a scale factor to coordinates.
Rotate coordinates

Rotate coordinates screen

About Pt:
Enter the point number to rotate about or to use as a basis for translation, and press Tab. The existing coordinates for that point are displayed. To keep those values, press Tab with no entry, or enter new coordinates and/or elevation. The difference between the old and new values will be added to all specified points. Or you can enter a point# to translate to later.

2nd Pt:
Enter a second point number to define the line to be rotated, and press Tab. If translating or scaling only, any point may be used. The existing bearing of the line appears in the bearing field.

Bearing:
Enter the angle of rotation or the desired bearing and press Tab. To recall a bearing between 2 points, enter the point numbers separated by a comma. Enter 0 then press AR if translating or scaling only.

Trans pt:
Enter a point number to translate to, and press Tab. The existing coordinates for that point are displayed. To keep those values, press Tab with no entry, or enter new coordinates and/or elevation. This field may be left blank for no translation or if you are entering coordinates.

Scale:
Enter a number to use as a scale factor (multiplier) and press Tab. For example, to convert from metres to feet, use a scale of 3.280833333. Use the default value of 1.0 if no scale factor is required.

First:   Last:
Enter the first and last point numbers to which the rotation, translation and/or scaling is to be applied and press Rotate when ready to perform the computation.
-OR- Press Sets to rotate a list of points defined in the Plot function. Make sure you don’t include a point more than once in the set, or it will get rotated twice.

TO DXF

Transfers the current coordinate file to a DXF file (drawing exchange file) This file can then be transferred to your desktop PC and imported into most any CAD software.
Coordinates to DXF screen

File name:
Enter a filename to store the DXF file. The program will add an extension of .DXF if you don’t enter one.

Check the Send Elevations or Send Descriptions boxes to include elevation labels or descriptions with the points on the drawing.Check the Auto linework box to create linework that is generated automatically from your point descriptions. See CADcodes for more information on how points and lines will appear in the DXF file.

First pt:   Last pt:
Enter the first and last point numbers of the range of points to transfer.

If you are using CADcodes with symbols, you will need to define each Symbol Block in the BLOCKS section of the block.DXF file. To define blocks for DXF, you should make a drawing containing all the usual symbols you use, and then DXFOUT the file. Then using Notepad or a word processor, you need to find and cut the blocks section starting with:

0
SECTION
2
BLOCKS
And all text up to and ending with:
0
ENDSEC

Then paste this text replacing our default block file in: \Program Files\Fieldworks\block.dxf The text in this file is automatically placed at the start of all DXF files.

TO RS232

Transfers a range of coordinates from the current file to the serial port, formatted for a Geodimeter 600 instrument Area or Job file, or a generic ASCII file if you have any other instrument chosen. If you select No Elevations in the Options function, the file will not contain elevations. Before entering this function, make sure you get the instrument connected and waiting to receive a file.

Area file? hit Yes
Job file hit No
(Geodimeter only)

First pt: Enter the first number of the range of points to transfer.
Last pt: Enter the last of a range of points to transfer.

Area File name:
Enter a filename for the area file. (Geodimeter only)

FROM RS232

Reads an Area or Job file from a Geodimeter 600 instrument, or a generic ASCII file from the serial port if you have any other instrument chosen. This can be used to send a coordinate file directly between 2 data collectors or other computers/instruments that have the ability to send/receive ASCII files, start the receiving one first, then start the sending one within 1 minute. Make sure the Baud rate and settings match on both ends. These questions will appear if you are using a Geodimeter instrument.

Area file? hit Yes
Job file hit No

Area File name:
Enter a filename for the area file. All the points in the selected area file will be read and stored into the current coordinate file. Note that if you bring points into a file which already contains points, you must be careful since there is no point protect option here. Make sure your instrument is connected.

TO CAD

Transfers a range of points to PocketCAD. (Not on the desktop version.) Make sure you have turned on the plot-as-you-go function in CAD (see page 50) before running this or nothing will show up. Normally if you keep the plot-as-you-go function on as you create points you will not need this function, but if you have points that didn’t make it into a drawing yet, this is one way to get them there.

First pt: Enter the first number of the range of points to transfer.
Last pt: Enter the last of a range of points to transfer.

AVERAGE

This function is used to average a series of coordinates and display the standard error. It is useful with GPS systems since you can set Fieldworks to record a shot at a given time interval like every 10 seconds, (see AutoSS under Tools-Baud Rate) leave it there for a while, then after collecting any number of shots on the point, use this function to find the average. This makes even a cheap handheld GPS get you a fairly accurate position. It can also be used with RTK systems to get a more accurate autonomous position for the base which can improve your RTK accuracy. You may also want to use the Plot function to visually see the spread of points.

First point #
Enter the first point number.
Last point #
Enter the last point number in the group of points to be averaged. The program then displays the RMS standard error of the points both horizontal and vertical, then press OK.

Save as point#:
Enter a point number to save the averaged coordinates.

Delete original points?
Press Yes to delete the original points (from first to last) or press No to keep them in the file.

FILE – OUTPUT

This function is used to send a file of commands out the serial port, especially for custom GPS applications like changing the elevation mask, starting/stopping logging of static data, or nearly any other function on the GPS. The file should have an extension of .CMD and contain one command per line, and is normally created on your desktop computer using notepad or a word processor, and then copied to the mobile device \My Documents folder.  The only prompt is to select the file to be sent, then Press OK to start Output.
