BG-Map Surveying Tip
Mapping Non-Plant Objects with the BG-Map Total Station Interface and GPS Interface
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
MAR Ground markers, monuments
NPO General symbol for non-plant objects
PAT Points along a path
POL Utility poles
ROA Points along a road
UNA Unaccessioned Plants
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.
