Mobile Mapping with ProMark3

The ProMark3 system is also designed to log GIS features in

a job file.

GIS features can be of the following types: points, lines, areas

and grids. Grid features are Magellan’s specific features de-

tailed in Logging GIS Data on a Preset Grid Feature on

page 134.

ProMark3 provides in real-time the length of the line you are

logging or the surface area of the area you are logging.

You don’t need an external antenna or any other accessories

to collect GIS jobs. You just need to hold the unit at 45° from

horizontal, not too close to you, and make sure you constantly

have an open view of the sky.

If however you want your GIS surveys to benefit from the RTK

precision level, you will have to use an external antenna and

set the RTK surveying method as explained in

RTK Setup on

page 34.

When you start a new GIS job, ProMark3 asks you to:

1. Choose a feature library for the job.

A feature library lists all the possible feature types you will

see in the field. It also provides all the possible attributes

for each feature type and all the possible values for each

attribute.

After you have chosen a feature library, you will only be

able to log features that comply with those prompted in

this library. You will not be able to add an extra feature

type or an extra attribute to an existing feature. So choos

ing a library implies that you know the type of job you

want to do.

2. Choose between Real-Time and Post-Processing.

GIS features can be logged in Real-Time or Post-Process-

ing mode.

In Real-Time mode, any logged feature is georeferenced

using the real-time position determined by the ProMark3.

In Post-Processing mode, it is also the real-time position

that is associated with each logged feature but you have

the possibility to improve the accuracy of this real-time

solution through post-processing. This can be achieved

using MobileMapper Office.
