Q. I have
installed my digitizing tablet and the Wintab driver,
but Didger does not work with the
Connectivity between the digitizing tablet and the
Wintab driver often requires certain information that
can only be obtained from the tablet manufacturer. If
you have installed both the driver and tablet, but the
puck on the tablet does not act as a mouse on your
screen, you can be assured that the driver is not
properly installed. Please contact your tablet
manufacturer for proper settings for both the tablet and
the driver. In our experience, tablet manufacturers can
quickly and easily get you up and running with your
Q. What are
the communication parameters needed by Didger for my
A. Didger does not require any specific
communication parameters. Didger requires only that you
use a 32bit Wintab driver that can be obtained from your
tablet manufacturer. Please consult our manufacturer
list for contact information.
Didger support stream mode digitizing? Is it possible to
trace a contour line by just keeping a button on the
puck pressed while following the line with the
Didger does support stream mode digitizing. When
digitizing in stream mode, it is important to set the
vertex tolerance setting. This setting sets the minimum
spacing for vertices along a polygon or polyline. When
you have set a vertex tolerance value and you are
digitizing a polygon or polyline, no two adjacent
vertices along the object can be closer together than
the specified length (but they can be farther apart than
the specified length).
Q. I cannot
seem to select the objects on my map. I can select them
from the data attribute view, but not the plot view.
What am I doing wrong?
A. Make sure that you have the layer set to
editable. In order to select the objects from the plot
view, the layer on which the objects reside must be set
to editable using the View | Layer Manager
Q. When Iím
importing a vector file with an underlying coordinate
system, and I try to change to a new coordinate system
in the import dialog box, my map doesnít look right at
all. What am I doing wrong?
A. Do not change the coordinate system
of a vector file when importing. Didger reads the
projection information from the file itself. Let Didger
import the file with the existing projection system.
Then, to change the projection, use the View | Change
Projection command and select the projection and datum
you wish to apply to your map.

all the polygons are created, only some of them. How can
I get all the marked polygons to become "closed"
endpoints of your lines are probably not within the snap
tolerance value and therefore are not snapped to each
other. They must be snapped for the operation to
succeed. Increase the snap tolerance from the File |
Project Settings | Tolerance tab so that the lines are
snapped. Then perform the operation again.
Q. How do
I import a second vector file into Didger that has a
different projection than the first file I imported? I
want the projection system of the first file I
Import the first file and accept the projection
information displayed in the Define Import Options
dialog box. Then use File | Import Vector to import the
second file. Check the Apply Datum Conversion check box
and click OK. The second file will be transformed to the
projection of the first.
Q. I have
a map that is larger than my tablet. Is it possible to
digitize the objects into one
the steps below for digitizing from a map larger than
- Divide the map into enough
sections so that each will fit on the digitizing
tablet. For each section, define between 3 and 256
- Place the first section of
the map on the tablet and go to File | New | Tablet
Digitizing. Calibrate the tablet according to the
instructions for calibration.
- Digitize all the objects
on that portion of the map. Save the work in a PJT
file using File | SaveAs.
- Go to View | Project
Limits and change the X and Y limits to reflect the
dimensions of the entire project area.
- Move the map so the next
section is on the tablet. Go to Digitize | Tablet
Calibration and click the Next button to go to Step
- Clear the existing
calibration points by clicking the Delete Point
button. Type in the calibration points for this
section of the map and complete the calibration of the
- Digitize all objects on
this section of the map and save the file.
- Continue in this manner
until you've completed the project.
Q. How do
I convert my Universal Transverse Mercator (UTM) data to
A. Didger 3 can convert data between 23
different coordinate systems, including UTM and
Lat./Long. To use Didger to convert UTM data to Lat/Long
data, please follow the steps below.
- Import the data file using
File | New | Import Data.
- Select the appropriate
delimiters so that your data are separated into the
fields you wish.
- Click the Import button
and the Define Import Options dialog opens.
- Set the Coordinate Space
Type to Projected and change the Map Projection
Category to UTM.
- Then you will need to set
the System to the zone in which your UTM coordinates
are located and click OK. Your data will display in
the plot window.
- Next, go to View | Change
Projection and change the Map Projection Category to
World/Continental. The System should then report
- Click OK and the data will
appear in Lat/Long.
- Go to File | Export and
select DAT as the file type. Once exported your UTM
data will be in Lat/Long.
Q. I am
having a problem printing ("Out of global memory" error,
only a portion of the map prints,
A. You may
be able to work around the problem by changing some of
the printer settings. Different printer drivers have
different settings, but here is a list of the most
- Turn off print
- Change the print mode to
"raster" or "bitmap" to reduce the printer memory
- Change the printer driver
to use the computer's memory instead of the printer's
- PostScript drivers often
require more memory than non-PostScript drivers for
the same printer. Change drivers if possible and test
the print results.
- Check for other compatible
printer drivers in your printer documentation. For
example, the HP LaserJet 4 driver could be used with
the LaserJet 5 printer.
- Enable the Page Protect
mode if available.
- Verify the version of your
printer driver and possibly update it. For example,
the HP DesignJet 750C driver version 4.33 requires 80%
less memory than version 4.11
- Turn off View | Auto
Redraw to free up additional memory.
- Resample the bitmaps in a
graphics program (Corel Draw, Paint Shop Pro,
PhotoShop) to reduce the number of pixels and color
depth in the bitmaps.
If the remedies above do not
help, please contact technical support with the exact
nature of the problem, your operating system (i.e.
Windows 98), the printer model, and the print driver
Q. How can
I digitize a graph that has a non-linear X axis, but has
intervals of linearity?
A. Didger 3 was not designed to easily handle
non-linear axes. You have two options when it comes to
digitizing non-linear axes:
- You can digitize it into
one PJT file. You will have to digitize a section with
a linear portion of the X axis, then change the
project limits (to reflect the entire project), move
the map, recalibrate the tablet, and digitize another
section that has a linear portion of the X axis. This
file will make a linear X axis, ranging across the
entire X axis min/max values, and your digitized
objects will be spread across it.
- You can digitize the
profile into a number of PJT files - each one
containing a section of the profile that has a linear
Q. How can
I resample my well log in a raster project? The option
is grayed out.
The Tools | Resample Polylines command is not available
with raster projects. If you have a raster project,
export the polyline(s) to a vector file format (like DXF
or GSB), then import the vector file back into Didger
into a vector project and perform the
Q. How can
I export the Data Attributes table to a data
A. In Didger
3, bring up the Data Attributes table and activate that
window. Then go to File | Export Data Table.

Q. When I
am digitizing a line on-screen and then mess up, how can
I reverse the line a little and then go on (so I don't
have to stop and then redigitize the line all over
Didger 3, if you are digitizing a line, and then decide
you want to redigitize the last little bit, simply
right-click repeatedly (with the left mouse button still
held down) until your line is back where you want it to
be, then continue digitizing in the normal fashion. Each
time you right-click, the digitized line will back up to
the next vertice on the polyline.
imported a georeferenced bitmap into a vector file. The
vector file I want to overlay it with is in a different
projection. I want to change the projection of the
bitmap, but the View | Change Projection menu has
changed to View | Projection Settings. How can I change
the projection of my bitmap?
A. You cannot change the projection of a
bitmap imported into a vector project. To change the
projection of your bitmap, import it into a raster
project, specifying the georeference information. Once
the bitmap is imported, go to Image | Convert Image
Projection to convert the image projection to that of
the vector file. Once the projection is converted,
export it again as a GeoTIFF.
Alternatively, you can import
the vector file into a new vector project and use the
View | Change Projection command to change the vector
file projection to that of the bitmap. Once the vector
file is changed, you can use File | Import Bitmap | Into
Vector Project and import the georeferenced
Q. I have
a bitmap imported into my project and when I use the
Create Surfer Base Map command, the bitmap image isnít
transferred into Surfer. What is
Create Surfer Base Map command only supports bitmaps
that are imported into a vector project. If you have a
bitmap imported into a raster project, it will not be
exported into Surfer. If this is the case, export the
bitmap as a GeoTIFF and import it into a vector project
and use the Create Surfer Base Map command.
Create Surfer Base Map command is grayed out. I have
Surfer installed, what is wrong?
A. There could be a couple reasons why
this command is grayed out. Make sure you have Surfer 7
installed on your computer. This command will not work
with Surfer 6. This command will also be grayed out if
you have a raster project which only contains a
calibrated bitmap and no digitized objects. In this
case, the command will be grayed out since there are no
objects to export to Surfer.
Q. I have
a bitmap imported into my project. I want to warp it,
but the command Image | Warp Image is grayed out. What
Image | Warp Image command is only available in raster
projects where the image has been calibrated with linear
axes, and no objects have yet been digitized on the
image. Make sure you have imported the image into a
raster project and go to Image | Calibrate Image. Make
sure your image is calibrated with linear axes (not
logarithmic). If there are any digitized objects on the
image, delete them prior to using this
Q. I have
a bitmap imported into my project. I want to change the
projection, but the command Image | Convert Image
Projection is grayed out. What is wrong?
The Image | Convert
Image Projection command is only available in raster
projects where the image has been calibrated with a
projection, and no objects have yet been digitized on
the image. Make sure you have imported the image into a
raster project. Go to Image | Calibrate Image and make
sure that there is a projection specified in Step One.
If there are any digitized objects on the image, delete
them prior to using this command.
Q. I drew
a polyline on my raster project and when I select it, I
can't edit the coordinates in the Coordinate
can only edit the coordinates in the Coordinate Manager
of objects imported into a vector project. In a raster
project, you can view the coordinates in the Coordinate
Manager, but you cannot edit them.
Q. How can
I save the coordinates in the Coordinate
is not a Save option for the Coordinate Manager, but you
can simply select the object you want to save the
coordinates for and go to File | Export, in the Export
dialog, check the check box in the lower left for
Selected objects only, and export it as a Golden
Software Data (*.dat) file.
Q. I drew
a polyline on my raster project and when I select it,
the File | Export LAS File is grayed
A. To export
a polyline to an LAS file, the polyline must be
resampled (Tools | Resample). Polylines cannot be
resampled in a raster project. To overcome
- Export the polyline to a
- Go to File | New | Import
Vector and import the DXF file into a vector
- Select the polyline and go
to Tools | Resample and resample the polyline.
- Select the polyline and
use the File | Export LAS File command.
calibrated my raster image in a raster project, exported
it with georeferencing information. When I try to import
it into a vector file I get an error that it is not
A. The reason why you are getting the "The selected
bitmap has not been properly georeferenced" error
message is because the raster image is not rectified. If
you are georeferencing an image in a raster project for
use in a vector project, you have to use the Image |
Warp Image command in the raster project prior to
exporting it as a GeoTIFF.
Q. How can
I change the number of decimal places in my Graticule or
decimal places for the graticule or grid is controlled
under the Numeric Display Format found by going to File
| Project Settings under the General tab. If a graticule
or grid is already created, you must change the Numeric
Display Format, then recreate the graticule or

to select all the polylines and points in my project. I
go to Edit | Criteria Select and choose to select Object
Type (Polyline) And Object Type (Point), but
nothing gets selected. What is
And condition is designed so that the second
criteria is a subset of the first criteria. To select
using two separate criteria, use the Or
condition. For example, choose to select Object Type
(Polyline) Or Object Type (Point).
Q. I have
calibrated my bitmap in a raster project. I want to
overlay a vector and data file on top of it, but these
commands under the File menu are grayed out. How can I
A. If you
have a bitmap in a raster project, you cannot import any
additional files into the raster project. To overlay a
vector or data file on top of a bitmap, export the
calibrated bitmap from the raster project as a GeoTIFF.
Import this GeoTIFF into a vector project. Once the
bitmap is imported into the vector project, you can
overlay vector and data files on top of it.
Q. I try
to select an object in my project, but whenever I click
on it, another nearby object gets selected instead. How
can I select the object I want?
A. Sometimes it is difficult to select
objects that are near to each other. If you click on an
object to select it and another object gets selected
instead, hold the Ctrl key down while clicking. The Ctrl
key will allow you to scroll through the selection boxes
until the correct object gets selected. Alternatively,
you can also select the object in the Data Attribute
Q. I have
a map in Transverse Mercator projection. I go to Tools |
Coordinate Conversion and specify a Georeference
operation. I enter in my new coordinates in meters,
choose Affine as my georeference method and click OK. My
map looks very bad now! What am I doing
A. If your
project has an associated map projection, the values you
enter under the Georeference operation must be in units
of latitude and longitude.
Q. When I
export my file as a WMF to insert into Word, the WMF
file has really low resolution. How can I make it look
3 is a step toward the phasing out of the Windows
Metafile format [*.WMF]. This is in response to
Microsoft Windows (along with numerous applications)
doing the same thing. Essentially, the WMF format is
'outdated' in comparison to the EMF format. To export a
high resolution metafile, export to an Enhanced Metafile
Q. All the
projection information is lost when I import my
georeferenced bitmap into a raster or vector project
using an ESRI World file. What am I doing
can import TIFF files with ESRI World file [*.TFW]
georeference information, but the projection information
is lost because the ESRI World file does not contain
projection information. You can remedy this by setting
the projection parameters of your image in Didger and
exporting the image as a GeoTIFF. To do this, follow
these three steps:
- Import the file into a
raster project, using the georeference information
from the ESRI World File.
- Go to Image | Calibrate
Image and specify the projection parameters. Click
Next until you finish the calibration process without
changing anything else.
- Go to File | Export and
export the file as a TIFF file saving the spatial
reference information in GeoTIFF Format.
Q. I am
trying to use my GPS unit to digitize on top of my
raster image. I have the image imported into a raster
project, but the Enable GPS command is grayed out. I
have checked all communication settings and can find no
GPS Digitizing feature is only available with vector
projects. Georeference your raster image, export it as a
GeoTIFF, and then import it into a vector project. Once
the image is loaded into a vector project, the Enable
GPS command will be active.
Q. How can
I export my file as a GeoTIFF?
A. To export as a GeoTIFF file, follow
- Go to File | Export and
choose to Save as Type: Tagged Image (TIFF) (*.tif).
Type in a file name and click Save.
- The Tagged Image (TIFF)
Export dialog will pop up.
- In the bottom section,
choose the radio button next to Save spatial reference
information in and then check the check box next to
GeoTIFF format. Click OK.
- The file will be exported
in GeoTIFF format.
Q. My map
is projected in the Mercator projection and I want to
export it to a BLN file with units in Lat/Long. How can
I do this?
Projected maps can only be exported in Lat/Long
coordinates if the project is a raster project. If your
map is in a raster project, simply go to File | Export,
choose BLN as the file type, enter the file name, and
click Save. The Export Options dialog pops up. Click on
the Projection Options tab and choose to export in
Lat/Long (dec. deg) and click OK. The BLN file will
contain the coordinates of your project in Lat/Long
If you are in a vector
project, the only way to export in Lat/Long coordinates
is if your projection is set to Unprojected Lat/Long. Go
to View | Change Projection and set the Category to
World/Continental Projections and set the System to
Unprojected Lat/Long and click OK. Then go to File |
Export and export the file. If your vector project is in
any projection other than Unprojected Lat/Long your file
cannot be exported in Lat/Long (dec. deg)
Q. My map
is projected and I export it in units of feet. When I
import it into MapViewer, it looks a little distorted
and it doesnít overlay with my MapViewer maps. What is
MapViewer, and possibly other applications, only imports
projected maps with units in meters. There is not an
option to specify input data units. Therefore, the map
coordinates in feet are being viewed by MapViewer as
meters and causes shapes to be distorted and for it not
to line up correctly with the MapViewer maps. We suggest
you export from Didger using meters if you are going to
use the projected map in MapViewer.
Didger work with Windows 2000 and Windows XP?
All Golden Sftware
products work with Windows 2000 and Windows XP. There
have been no problems reported.
Q. Why does the
Warp Image command flip my image upside down when it is
calibrated with a descending axis?
A. The Warp
Image command is not intended to be used with a
descending axis. If you want to warp your image, the
image must be calibrated with ascending axes (the Y axis
increasing upwards and the X axis increasing to the
