BG-Map Surveying Tip

Mapping Non-Plant Objects with the BG-Map Total Station Interface and GPS Interface

Updated 3/9/16

 This document explains how to use BG-Map for the automated mapping of non-plant objects. 



About Non-Plant Objects

BG-Map allows you to map certain objects other than plants using the Total Station Interface or GPS Interface. These "Non-Plant Objects" (NPO's) are entered into the palmtop computer or GPS data collector using codes to identify the type of object plus a specific ID number for each object.

When the field data is converted, the non-plant objects are automatically inserted into the basemap.


Entering Non-Plant Objects into the Palmtop Computer or GPS Data Collector

The following 3-letter codes are used to identify non-plant objects:

         ART     Artwork, sculpture, etc.
         BED     Bed outlines
         BEN     Benches (BG-Map 2016a or later)
         ELE     Electrical boxes, outlets, etc.
         FEN     Points along a fence line
         HYD     Fire hydrants
         IRR     Irrigation devices
         LAM     Lampposts
         MAN     Manholes
         MAR     Ground markers, monuments
         NPO     General symbol for non-plant objects
         PAT     Points along a path
         POL     Utility poles
         ROA     Points along a road
         SPI     Spigots
         TEL     Telephone
         UNA     Unaccessioned Plants
         VAL     Valves

Each NPO is entered into using the following format:

Code * ID Number

So, for example, to enter a hydrant and have it identified on the map as hydrant number 12345, key in the following into the palmtop or data collector as the plant "Accession Number":


To enter manhole number NW27, key in:


NPO's are always entered as "Single Plants".


Placing Non-Plant Objects into the BaseMap


If you are accessing your basemap through a network: Before Proceeding, make certain that your basemap is not opened in "read-only" mode. That would prevent you from being able to save your symbols.

It is also a good idea to print out the raw field data containing the NPO's before proceeding. This will provide you with a backup of their locations should something go wrong.


Determining the Layers on Which the Symbols Will Be Inserted

Click Tools/Options/NPO Layers to determine which layers the NPO symbols will be inserted on. Otherwise, all symbols will be inserted on the NPO layer by default

Uploading the Data

Upload the field data containing the NPO's - click Field Data/Upload. Print it out as a backup.

Make certain that your basemap is open with read-write rights and that AutoCAD is at the Command prompt.

Convert the field data - Click Field Data/Convert. The NPO symbols will be automatically inserted into the basemap. You will be prompted to save the basemap.
