Road Atlas of BCGIS Innovations Ltd. Will deliver to our clients the Road Atlas of BC by a number of ways, one of which is the data in an FDM dispatch ready format.
FDM
uses a 4 column naming schema: Prefix, Name, Type, Suffix, hereafter referred
to as (PNTS).
For
all of BC, the incoming name schema is commonly the Telus
MSAG format: Name and Vector. Also, and
this is critical for FDM users to understand, the MSAG has a legacy issue of a
relatively short character length limit.
This has lead Telus to use both standard
abbreviations and conventions to generally shorten names, and if more length shortening
is required, non-standard abbreviations.
Given
these two very different designs, GIS Innovations uses several internal
techniques to get these two ideas to work together within an FMD system. The method used for each street name is
recorded into an extra field NAME_SOURC.

NAME_SOURC |
REMARK |
|
over-ride |
The PNTS rules are
ignored an a specially entered PNTS is used.
Typically used where the name is too long resulting in the MSAG name
as a custom string shortening. Also
used if the MGAS name varies with our name and neither are being changed (eg “ |

gisi_name |
Informal names
assigned by GIS Innovations, such as “unnamed FSR”, or “service road”. |
|
numeric |
The road is a
numbered (St, Ave, etc). These can be
delivered either as with an standard suffix (ST, ND, RD, TH) attached (our
default), or not. We need client
specific requests if a client does NOT want the numeric suffixes attached. |
|
gisi_strct |
The name is a GIS
Innovations special name, typically a name with a “structure” added. In these cases the entire PNTS is put into
the Name field. Eg.

The
Telus MSAG has some naming conventions that are
typically applied. These typically apply
to “key” words. In order of precedence, we understand these rules to
be:
|
NAME_SOURC |
REMARK |
|
autoOneWd |
If the Name
only has one word (whether the Type is present or not), do not abbreviate the
Name. Eg. |
|
autoPreFix |
If the “first”
word is a directional (C, N, S, E, W, NE, NW, SE, SW), OR the fully spelt out
form (eg: NORTH) and the PNTS does not already have a directional Prefix, then move the
leading directional key word out of the Name and place it’s directional code
into the Prefix field. Note: this can be over-ruled by
the GIS Innovations setting up an over-ride. |
|
auto1stWd |
If the “first”
word is one of the following key word
abbreviations, then keep the abbreviated key
word. (MT, MTN, PR, PT, ST, HWY, FT), see full key table. |
|
auto1stWd |
If the “first”
word is one of the following key words,
then NO NOT abbreviate the key word. (CREEK,

If the key word appears, abbreviate it. |
