Creating a map in Farm Trac Plus
|
 |
Your Farm Works Software includes a CD with
USGS Road and Waterway data for an area representing one to five states.
Farm Trac Plus can read the data from this CD to create GPS referenced road,
waterway and other maps. With these maps, you can use the "Get from
the Web" feature in Trac Plus to download free; GPS referenced imagery
from the Internet. With the roads and waterways & images, a map of your
farm can be created. This map will be GPS referenced. When you take the
time to carefully draw your fields, Trac Plus can give you a very accurate
estimate of the size of each field!
Loading USGS Road & Waterway Maps (known as Quads)
U.S. Geological Survey maps (USGS Quads) are geo-referenced
maps of roads, waterways, railroads and other significant features. Quads
CDs typically contain map data for a one to five state area and a CD for
your area is included with Trac Plus. To load the maps for your farm into
Trac Plus:
- Select Map Setup from the File menu. The Map Setup
box will appear.
Insert the USGS Quads CD into your CD drive and select the Drive
from the drop-down list.
- Select the States to Import from the list to load maps with
county boundaries.
- Select Import United States Map to load a map of all US state
boundaries.
- Select Activate USGS Quads Map. This will make the quads layer,
which is used for selecting the area of your farm, your active layer
once it is imported.
- Click OK to load the selected maps. You will see a map of
the United States on the screen with county boundaries for the states
from step #3.
|
- Use the Zoom
tool
to zoom in on the area where your farm is located. You will now see
a series of yellow squares. Each yellow square represents a quad, which
is an area that you can import road and waterway data for.
- Using the Pointer
Tool,
select the quads to import. Hold downthe Ctrl key on your keyboard
to select multiple quads or click and drag to rubber band a section.
Selected quads will have a gray crosshatch pattern.

- Right click with your mouse and select Import Quads from the
menu. The Import USGS Quads box will appear.
- Select the type of data you wish to Import. Each data type will be
loaded to a separate layer.
a.
Roads and Trails: Includes streets, highways and roads.
b. Waterways: Includes lakes, rivers and creeks.
c. Railroads: Includes major railroads that have been mapped.
d. Misc. Transportation: Includes features such as major pipelines
and high overhead power lines.
- If your quads border a state boundary, they may be available on more
than one CD. In that case, you will need to select the CD # from which
you are loading the quads. The CD # is written on the front of the CD.
- Click OK to load the quads for your area.

- In the Import USGS Quads box select your CD-ROM Drive Letter
from the drop-down list and click OK. Depending on the number
of quads selected and the speed of your computer, it may take several
minutes to import the quads. Each type of data (roads, waterways, etc.)
for each quad will be loaded onto a separate layer.
- After the quads have been loaded, switch to the Layers tab
as shown on the right.
- Select the Layer Management button. The Layer Management
box will appear. Available Layers and Displayed Layers will be
listed.

- Available layers (which includes the newly imported road and waterway
layers) are listed under the project name in folders. Click on a Plus
+ sign to view the contents.
- Remove the US Quad Layer from the Displayed Layers list and add the
Main Farming Layer to the Displayed Layers list. The Main Farming
Layer is the layer where you will draw your field boundaries. This is
also the layer that will be used for field records. Items may be removed
from the Displayed Layers by double clicking on them. To add an item
to the Displayed Layers list, double click on the item in the
Available Layers. Items may also be added or removed by clicking
on them and using the arrows between the lists. The bottom arrow will
remove all items from the display.
- Select the Done button in Layer Management to display the selected
layers. Trac Plus will automatically color the roads red, the waterways
blue, the railroads black and the misc. transportation green.

Deleting Extra Roads & Waterways
You may find that the quads give you more data than you need. The following
steps will help you to delete data from the USGS Quad maps that you will
not need, such as roads and waterways that are not on your farm..
- Select the Layer Management button
to go to Layer Management and use the Remove All button
to remove all layers from display.
- Click and drag the Roads folder from the Available Layers to
the Displayed Layers. The result is that all roads will be displayed.
- Select the Done button and the layers will be displayed. If
all maps are not visible, select the
Zoom
All button (located in the lower left corner of the map screen).
- The Layers tab on the left will list the layers that are displayed.
The top layer (known as the Active Layer) is the layer you will
be working with. Use the
Pointer
Tool to click and drag to select any lines on the Active Layer that
you would like to delete. Multiple areas may be selected by using the
Ctrl key on your keyboard and clicking and dragging. Selected
lines will have dotted lines and will be flashing.
- Right-click and select Delete and the lines will be deleted.
- Select the next layer that you wish to work with (in the Layers tab)
and select the Top
button
to make the layer the top/Active Layer so you can delete the extra lines
on this layer.
- Repeat step #6 for each of the layers that are displayed.
- Repeat this entire process for Waterway, Railroad and Misc. Transportation
maps so each map layer contains only the data that you wish to use.

Setting up a Startup Combination of Maps for Display
Each time that you go into your Trac Plus project, the program will display
your maps. By default the program will only display the Main Farming
Layer, which will have your field boundaries and field records. The
following section will show you how to set the program up so it will display
other maps (such as Roads & Waterways) at startup:
- Select the Layer Management button
to go to Layer Management and use the Remove All button
to remove all layers from display.
Select
the layers to be displayed (in the Available Layers section)
and move them to the Displayed Layers area. Make sure that the
Main Farming Layer is listed as the top/Active Layer (in the Displayed
Layers).
- In Layer Management, select Save as Startup from the File
menu. This will cause Trac Plus to load this combination of layers each
time you go into the project.
- Select the Done button and the layers will be displayed.

Calibrating Aerial Photos from the Internet
Trac Plus includes a method to quickly and easily download free, geo-referenced
images from the Internet. To obtain the aerial images, you will need to
know at least one geographic coordinate in your area and have an active
Internet connection. Coordinates may be obtained from the USGS road and
waterway maps that you have loaded into Trac Plus.
Registering a Point
- To begin you will need to obtain at least one set of GPS coordinates
that are to the North and West of your farm. The easiest way to obtain
these coordinates is to use USGS road and waterway maps that have been
loaded into Trac Plus. Select the Layer Management button
to
go to Layer Management and display the road and waterway layer.
- Next switch to the Backdrop Tools and click on the Registration
Points
button.
The Registration Points box will appear.
Click
on a point on your map that represents the Northwest corner of your
farm. The coordinates will appear in the Registration Points box.
- Enter a Description that defines the location in terms you
will understand later: Smith Farm NW, for example.
- Click Record to save the information and click Done to close the Registration
Points box.
|
Downloading and Calibrating the Image
- Select the Calibrate
button from the Backdrop Tools button bar. The Calibrate
Image screen will appear.
- Select the Get From Web
button.
The Enter Coordinates box will appear.
Select
the Saved Location from the drop-down list for the point from step#4
in the previous section: Smith Farm NW, for example. Alternately, you
may enter the coordinates for the point. Be sure to select Approx.
Top Left Corner for the Location of Point option. Click OK
to continue.
- The image will automatically be downloaded from the Internet and will
be calibrated with geo-referencing data. The downloaded image covers
an area approximately 1.2 miles East and South from the selected point.
Note that depending on the download speed of your Internet connection,
this process can take anywhere from a minute to several minutes.
- The map will now be displayed in the Calibrate screen. Select the
Save As
button
to save the image.
- The Save As box will appear. Enter a name for the file (such
as Smith Farm). The program will default to saving the file in the C:\Farmproj\Images\Backdrop
folder/directory.
- Click Save and the image will be saved.
- Select Exit from the File menu to close out of the Calibrate
screen and return to Trac Plus.
|
Loading the Image
- To display the downloaded image in Trac Plus, select the Load
button in the Backdrop
Tools. The Load backdrop box will appear.
- Select the directory in which the calibrated image was saved. This
will normally be the C:\Farmproj\Images\Backdrop folder, which is what
the program will default to.
- Select the file from Step #6 from the previous section.
- Select the Open button to load the image onto the current
Active Layer (likely the Main Farming Layer). The scanned map will appear
on the screen.
- If the image does not cover your entire farm, repeat this process,
for the next area that is needed.
The USGS Roads & Waterways and the imagery are not perfect and there
may be times where the maps do not line up exactly. Normally this is due
to one of the maps being shifted. To fix this and make the maps line up:
- Display the Road & Waterway Layers along with the downloaded
imagery.
- Select the Zoom Tool
and
zoom in on an intersection of two roads or a road and a ditch that is
visible on the imagery.
- Select the Move
button in the Backdrop Tools.
- Position your cursor over the intersection on the image. Then hold
down the left-mouse button until your pointer turns to a hand and drag
the image until your cursor is over the same intersection on the USGS
roads and waterways.
After all of the images are loaded and lined up with the roads and waterways,
you can start drawing and defining your field boundaries on the Main Farming
Layer. Fields will typically be drawn using the Multi-Line tool
(from the Mapping Tools toolbar). With the Multi-Line tool, you
will left-click around the corners of each field to trace the boundary.
When the boundary is completely drawn, you can right-click to stop drawing.
Hint: When drawing a boundary it is very important to not
leave gaps. Gaps can be caused by not stopping a boundary where it was
started. To insure that there are no gaps, turn on the End Point
tool by pressing the <e> key on your keyboard before you click
on the last corner of the field (the same corner where you started drawing).
This will snap the end of the last line to the start of the first line.
Pressing the <e> key again will turn off the End Point tool.
Once a field is drawn, it can be defined by selecting the Define Objects
tool from the Mapping Tools toolbar and clicking inside the boundary.
When this is done, Trac Plus will display the acreage for the field and
will ask for details such as the field name, landlord and other important
information.
