General Questions
Q1: What does GIS stand for?
A1: Geographic Information Systems (GIS).
It is a computer mapping system that is used to
display and analyze geographic information and
spatial databases.
back to topic
Q2: When did
the new digital GIS mapping requirement go into
effect?
A2: The requirement was included in the
new state regulations that were adopted on November
4, 2004.
back to topic
Q3: Where can I find
this regulation?
A3: All of the relevant laws and regulations
with regard to construction permit applications
can be found on the Division
of Water Supply's Statutory Authority webpage.
The relevant passage regarding GIS submissions
can be found under the New
Jersey Safe Drinking Water Act rules (Pdf Format)
under N.J.A.C. 7:10-11.5(c)6 (page 37).

Q4: What does the
Department plan on using the data for?
A4: Paper maps have become obsolete when
organizing and analyzing spatial data. The Department
has planned numerous analyses of and uses for the
digital data such as long term planning, disaster
response, master plan development, and updating
its water service area layer.

Q5: Does the Department
have a security policy in place to keep this information
confidential?
A5: Yes. Only a very limited number of
individuals in the Water Supply program have access
to the detailed data on water system components.
If more information is necessary please contact
the Water Supply's security expert at 609-292-5550.

Q6: Is there funding
available?
A6: Currently, there is none.

Metadata Questions
Q1: What is metadata? Can you provide more information regarding metadata?
A1: The Department's Bureau of Geographic
Information Systems (BGIS) website is a valuable
tool for all questions regarding metadata (http://www.nj.gov/dep/gis/metastan.htm).
The site also includes a FAQ on metadata (http://www.nj.gov/dep/gis/faqmeta.htm).
There are also FREE metadata tools available on the following site: http://sco.wisc.edu/wisclinc/metatool/.
back to topic
Q2: How do I know I've included all of the relevant information in the metadata?
A2: The BGIS provides a generic metadata
checklist (http://www.nj.gov/dep/gis/metahelp.htm - 5th bullet point) that can help you determine
if all of your information has been included.

Format Questions
Q1: Where are
the DEP Mapping and Digital Data Standards located?
A1: They can be found on the Department's
Bureau of Geographic Information Systems (BGIS)
website: http://www.nj.gov/dep/gis/njdepstandards06.pdf (Pdf Format)
back to topic
Q2: Does the
Department have a base map?
A2: No. However one possible method would
be to use the 2002 Orthophoto tiles (Aerials) (http://njgin.nj.gov/OIT_IW/index.jsp)
in combination with Roads (TIGER) (http://www.nj.gov/dep/gis/tgr2000shp.html)
to create a digital data set for your water system.
back to topic
Q3: Does
the Department have a template that we can use?
A3: Not at this time. The Department accepts
several different formats. One such suggestion
would be to submit the following:
- Point
- Sources (Wells and Intakes), Storage Tanks,
Treatment Plants, Interconnections, and Pump
Stations
- Polyline
- Distribution System Pipes
- Polygon -
Water Service Area
Each of the above should be
labeled in the attributes tables (i.e. Wells, storage
tank names, size of mains, etc.). Also metadata
file should accompany each of the above listed
submissions.
back to topic
Q4: Are hydrants
and valves necessary to include as part of the
distribution system?
A4: No, at this time the distribution system
is only considered pipes, interconnections and
pump stations.
back to topic
Q5: Do I need
include pipe sizes and materials of pipe?
A5: The Department asks that you provide
as much information as possible. The pipe size
is critical for any distribution mains (no service
connections). Regarding the material of the pipe,
if the information is not readily available, the
Department is not requiring systems to provide
that information at this time.
back to topic
Q6: Are CAD files
acceptable?
A6: Yes. The acceptable formats can be
found in section 6.0 and 6.1 of the Department's "Mapping
and Digital Data Standards" (Pages 11-12).
back to topic
Q7: Our CAD drawings
include curb lines and trees, should we include
them as part of the submission?
A7: The only five required items for existing
and proposed areas are as follows:
- Distribution
System (pipes and pump stations)
- Sources (wells,
intakes, interconnections)
- Storage Tanks
- Treatment Plants
- Service area - defined in N.J.A.C.
7:10-11.5(c)6 as the geographical area within
which a water system operates for the provision
of water.
The
BWSWP would prefer that extraneous information
be removed prior to submittal, however it is not
required. If that type of additional information
(such as curb lines, trees, etc.) is included,
it must be documented within the metadata.
back to topic
Q8: Is it acceptable
to digitize our old paper maps?
A8: Yes, as long as the new electronic
submission is in an acceptable format. These formats
can be found in section 6.0 and 6.1 of the Department's "Mapping
and Digital Data Standards" (Pages 11-12).
Be sure the mapping meets the 1:12000 scale requirements.

Submission Questions
Q1: I included
my system's sources and storage in my submission
but I received a deficiency letter that said these
required items were missing. Why?
A1: Metadata is vital to the Department
understanding what you are submitting. The Department
will not make assumptions on what information is
included within the submission. Describing in the
metadata what is being submitted helps the Department
identify if all of the required items are included.
back to topic
Q2: I have already
had my permit approved, do I still need to submit
GIS?
A2: Yes. All water systems are required
to submit GIS as noted in N.J.A.C. 7:10-11.5(c)6
(page 37). Failure to respond may result in revocation
of permits, deficiencies with future applications
and possibly enforcement action.
back to topic
Q3: I've fixed
my deficiencies and resubmitted my GIS digital
data. How long will it take the Department to respond?
A3: The Department is trying to respond
to all re-submissions as soon as possible. If you
have any questions, feel free to contact the GIS
reviewer who issued the deficiency letter.
back to topic
Q4: When and
how will I be notified if my GIS submission is
approved?
A4: The Department will send out approval
letters to notify the water systems that their
GIS submission has been accepted.
