| GeoLinks
All Topo Maps V7 allows you to attach one
or more media (pictures, movies, hyperlinks) to any geographic coordinate
annotation. These links may be evaluated by right-mouse-clicking near the
annotation, or image links may be automatically shown as the mouse cursor
hovers near the annotation.
All Topo will automatically display
pictures and annotation information for the annotation that is nearest the
mouse cursor in the Auto GeoLink viewer. To enable the GeoLink/Attribute
viewer, click on the menu option 'View: GeoLinks, Attributes' or press the
shortcut key Shift-Ctrl-G.
Hovering the mouse cursor near a picture:
automatically displays the image
associated with the coordinate:
To manually connect media and links to an
existing annotation, right-click near the annotation and select 'Edit
Annotation'; the 'Edit Coordinate' dialog will be shown. Select the
'GeoLinks' tab:
Enter the address of the target in the
'GeoLink' box. To display a picture, include the full address to the
picture. If the media is stored on an accessible location, you can use the
'Browse for file' button to find the picture.
To enter a web address, use the form
'http:\\www.igage.com\index.html' To send email to an address when the
link is evaluated use the form 'mailto:\\gripes@igage.com'.

Attaching GeoLinks
The All Topo Auto GeoLink tool
automatically attaches JPEG images taken with digital cameras to GPS track
points or waypoints.
The Auto GeoLink wizard tool requires
that:
- your GPS record a time/date stamp with
track points or waypoints
- your .JPG images contain a recognizable
time/date stamp
Recording
a GPS Track While Taking Pictures
- Turn your GPS on and allow it to
acquire satellites, wait for the Estimated Position Error (EPE) to
drop below 20 - 30 feet.
- Estimate the time you will spend taking
pictures and choose a track point spacing that will not overflow the
track buffer on your GPS. Clear any track points from your GPS and
enable track recording.
- Select the display page on your GPS
that shows date and time. (You don’t need to set the clock on your
camera.) Take a picture of the GPS that shows the GPS date and time.
This picture will be used to correlate the GPS time with your camera's
time. (Don't change the camera's clock after you take the picture of
the GPS's time screen.)
- Now travel with your GPS turned on,
recording track points. Take pictures at your leisure. It is not
necessary to connect your GPS to your camera or computer. Make sure
the GPS is carried nearby the camera and that the GPS has a clear view
of the sky.
- When you are done taking pictures, turn
off the GPS or disable track point logging to insure that the GPS
buffer does not wrap.

Attaching Pictures to the GPS Track
Download all of the pictures from your
camera to a new folder on your computer (see the instructions for your
digital camera), then use the All Topo GPS Tool to download the GPS track
to the same folder. Open the GPS Track log and it will display lines and
track points over the
maps.
The Auto GeoLink wizard can be started
from the 'Tools: Auto GeoLink…' menu selection:
Use the '…' button to the right of the
'Source Image' entry to browse for the folder containing the pictures. Every picture will be listed by the date/time order
extracted from the picture. Click on the picture that you took of the GPS
date/time screen.
Select the nearest matching track point in
the 'Eligible Annotations' grid (the GPS track point that was recorded at
nearly the same time that you took the picture of the GPS.) If you cleared
the track points from your GPS when you started, the correct track point
will be near the top of the list and the minutes and seconds will very
nearly match the time shown on the picture of the GPS. (Press and hold the
shift key, then use the mouse to zoom in to read the GPS time.)
Next enter the track point spacing you
programmed the GPS for (typically 10 seconds.) Check the 'Add Camera with
Link' box to add a camera icon to each annotation point that is linked.
Finally press the 'Attach Matching' button. All Topo will correlate the
images and track points. If you took pictures more often than the track
point spacing, All Topo will attach multiple pictures to a single track
point.
When All Topo finishes attaching images,
close the Auto GeoLink tool to return to the All Topo viewer. Click the
main menu option 'View: View GeoLink, Attributes…' option to display the
Auto GeoLink viewer. You may need to adjust the windows on your screen so
you can see both the map and the GeoLink viewer.
As the mouse cursor hovers near a GeoLinked
point the linked image will be displayed. |
