Features
The primary part of a feature code is called a feature. Features
generally describe what an object is. Two types of features are used
in Survey Pro: points and lines, which are described below.
When assigning a feature to data that was collected in Survey Pro,
only features of the same type are available for selection. For
example, if selecting a feature to describe a point in a job, only the
point features are displayed. Likewise, if selecting a feature to
describe a polyline, only the line features in the feature file are
displayed.
• Point Features
A point feature consists of a single independent point.
Examples of a point feature would be objects such as a tree, a
utility pedestal, or a fire hydrant.
• Line Features
A line feature consists of two or more points that define a linear object,
such as a fence or a waterline. In Survey Pro, these are stored as
polylines, but line features can also be used to describe alignments.
Attributes
A feature, by itself, would not be useful in describing a point or line
with much detail since a feature only helps describe what the stored
point is. Attributes are used to help describe the details of the object.
Attributes are either typed in from the keyboard or selected from a
pull-down menu and fall into the following three categories.
• String Attributes
A string attribute consists of a title and a field where the user can type
any characters from the data collector’s keypad up to a specified
maximum length. An example of a string attribute is an attribute titled
Notes where the user would type anything to describe a feature.
• Value Attributes
A value attribute accepts only numbers from the keypad. These
attributes are setup to accept numbers that fall in a specified range.
Some examples of a numeric attribute would be the height of a tree or a
utility pole’s ID number.
