Attributes

Attributes are an important part of a layer since they are

designed to hold specific information (other than position)

that you want to collect for each feature.

There is no limit in the number of attributes you can create

in a layer.

Each attribute is defined by a name (22 characters max.) and

a type.

You may decide to make an attribute a “mandatory”

parameter to describe any feature you will log in the layer.

This means the operator won’t be able to complete the

logging of a feature until the mandatory attribute has properly

been defined. Any type of attribute may be made mandatory.

There are eight different attribute types of attributes, as

summarized below.
