“Ellipsoid” (no geoid used) and “EGM84” (global

earth geoid model) are the two default options. Other

geoids may be prompted in this field after you have

downloaded them to the receiver from the Internet via

the link found on the MobileMapper Software CD.

4. Tap OK.

5. The program now asks you to define the properties of the

layer. The table below summarizes the different properties

you should define for the layer, according to its type.

For more information on layer properties and how to define

attributes, see Layer Properties on page 16.

6. Tap OK when you are finished with the properties of the

layer. A message then asks you whether you want to add a

new layer.

7. Add as many layers as necessary, using the above

procedure.

Very Important! As long as you do not log a feature through a

given layer, you can still add new attributes to the layer but

once a feature has been logged, no more changes, apart from

those linked to the appearance you give to the features on the

screen, are allowed in the layer.

Adding Layers into

a DXF Job

The procedure is quite similar to attaching a layer to a Map

job. Among the similarities are first the prior necessity to

define a coordinate system for the job and second, the

availability of the same viewing options and attributes for the

features you will log through a given layer (see Adding

Existing Layers to a Map Job on page 19 for the details).

But unlike Map jobs, DXF jobs cannot use or re-use layers

that are external to the job. With DXF jobs, you can only

create one or more new layers within the job, right after

defining the coordinate system. Another difference lies in the

absence of an assumed feature geometry in a layer, which
