Getting to know LandView Home
We will cover the following functions of LandView
Learning these major functions provides a basis
for discovering other LandView options on your
own.

Getting to Know MARPLOT
From LandView Home, click
The MARPLOT Program will open.

Marplot Navigational Tools
The Arrow Tool is used to move the Focus Point
, and to select objects.
The Hand Tool is used to make adjustments to your
map display
Clicking on the map with the Zoom-In or Zoom-Out
Tools will change the scale of the map by a
factor of 2, and the click point becomes the
center of the new display.
The Tape Measure Tool measures distance and
compass degrees, displayed at the bottom of the
screen.
In addition, clicking and dragging with the
Zoom-In Tool opens a new map window that zooms to
the dragged area.

Use the Zoom-In Tool, click and drag around
Arizona.
A new window will open zoomed-in to the dragged
area around Arizona.
9
Use the Zoom-In Tool, click and drag around
Maricopa County.
The use of multiple layers shows too much detail
at this level to be useful. However, we can
adjust the layers to our liking.

and roads. This process of Hiding and Showing
Layers is used repeatedly to achieve the optimal
look for your specific
project. Please note that the MARPLOT mapping
software is designed and best suited for creating
large scale maps. A large scale map shows a great
amount of detail for a small area
