Making or Using a Survey Plan Using Delph Nav

24 CHAPTER 1: Using DelphNav™ (Survey Control Panel) 2004.06.28

Importing Coordinates in Latitude and Longitude

When importing coordinates in Lat/Long format, the following formats are supported:

• Decimal Degrees, DD.DDDDDD (e.g., 57.234567, 03.005678)

• Degrees Decimal Minutes, DD.MMDDD (e.g., 57.14074, 03.003407)

• Degrees Minutes Seconds, DDMMSS.SS (e.g., 571404.44, 030020.44)

Note: No spaces are allowed. Positive longitudes are east, negative are west. Positive

latitudes are north, negative are south.

To import lines or points from an ASCII file into DelphNav

1. Click the Import objects from an ASCII file button (icon shown to the

right).

The system displays an Open dialog box.

2. Browse for and select the ASCII text file to be imported; click

Open to

import it.

The system displays the ASCII importation setup dialog box (Figure 13).

In the example shown in Figure 13, the ASCII file only has Eastings and Northings,

and they are correctly arranged (Eastings first, then Northings) according to the default

import option of DelphNav. However, the default Positions, Descriptions, and Units

can be modified to accommodate different layouts or units (e.g., Latitude and Longi-

tude in decimal degrees).
