Layer Specifications
PLFD File Submission 7 23 June, 2005
8
What's required in the CAD file

• Only the 5 layers (9, 10, 17 28, 40) are
  required, with the drawing entities placed on the
  correct layer.
• The proposed disposition and surrounding
  information must not be split into segments and
  must be georeferenced to the March 2005 ATS.
• Details, key plans or other information do not
  need to be shown in the submission drawing.

PLFD File Submission 8 23 June, 2005

What may be in your drawing file now

• All layers and entities to represent the survey
  are present in the drawing.
• More than one view may be shown in model space.
• Required layers for submission may not be present
  in the drawing or the information may not be on
  the required layers.
• The drawing may not be georeferenced.
• The site may be split into sections.

PLFD File Submission 9 23 June, 2005

PDF File Plan of Record

• The PDF document requirements have not changed.
  We are not trying to change the way you work.
• Create the CAD drawing using your current
  process.
• Create the PDF for submission using your current
  process.

PLFD File Submission 10 23 June, 2005
11
Modifying an Existing Drawing

• Once the PDF is created, the CAD file can be
  modified to meet the CAD submission requirements.
• Ensure the plan is complete, not split into
  segments and is drawn to full scale.
• Ensure the required layers exist. Create layers
  as needed.
• Move or copy the entities to the proper layers
  using the available AutoCAD functions. Audit the
  layers for compliance (e.g. no symbol blocks).
• Georeference the plan.
• If desired, isolate the required layers and write
  the plan to be submitted as a block.
• Prepare the layout view for the PDF creation and
  create the PDF file.
• Create the metadata file using Ddips.

PLFD File Submission 11 23 June, 2005

Plan View to be Continuous in Model Space- do
not split the plan into separate parts

• This is unacceptable for the CAD submission
• Remember to ensure the plan to be submitted (CAD)
  is whole, not segmented.

Plan View in Model Space

• The plan must be joined with no overlap
• The two segments shown in the previous slide have
  been joined into a single plan.

PLFD File Submission 13 23 June, 2005
14
Ensure the Proper Layers Exist

• Make sure the proper layers exist in the drawing.
  Create layers as needed to conform to the
  specifications.
• You will need layers numbered 9, 10, 17, 28, and
  40
• Other layers may be used, but their names can not
  interfere with the submission layers.

PLFD File Submission 14 23 June, 2005
15
Move the Entities to the Proper Layers - 1
If your existing layer structure does not meet
the specifications, the required information can
be moved to the specified layers without
interfering with your existing process.

• Use the specified layers for these entities
• 9 - Property And RW Linework, including other
  surface activities / dispositions, typically
  outside area of interest. ATS (section)
  linework broken for plot purposes.
• 10 - Text For Linework including other surface
  activities / dispositions, typically outside area
  of interest.
• 17 - ATS (Section) linework. Linework not to be
  broken and must be topologically clean. ATS
  linework must be complete for the entirety of all
  1/4 sections affected by the surface activity.
• 28 - Linework for disposition boundary, this
  linework shows the limits / boundaries of the
  disposition. In the case of an MSL and LOC on
  the same plan, the linework is not to be
  duplicated. This linework must be topologically
  clean, no duplicated linework and no dangles or
  undershoots.
• 40 - Surface Activity Code Text i.e. MSL, PLA
  (not required to be displayed on plot or image
  file) Insertion point must fall within the limits
  of the disposition.

PLFD File Submission 15 23 June, 2005

Move the Entities to the Proper Layers - 2

• You can use any of the AutoCAD tools to move or
  copy entities to the proper layers
• Layer translator
• Properties Sheets
• COPYTOLAYER command
• CHANGE command

PLFD File Submission 16 23 June, 2005
17
Isolate the Submission Layers
Alternatively, the layers can be isolated and
written to a new drawing.

• All non-required layers are frozen
• The plan entities are selected, then written as a
  block to a new drawing and the drawing saved and
  named as required

PLFD File Submission 17 23 June, 2005

Building upon the ATS Base
- The plan can be built upon the existing ATS
Base.

Georeference the Plan ALIGN Command 1Overview

• Use the AutoCAD ALIGN command to reference
  drawing points to known co-ordinates.
• Select all entities within the plan.
• Choose the first point and enter the reference
  co-ordinates. Repeat for the second and third
  points.
• All the selected entities should re-align to the
  specification.

FAQ
Q I use a pattern/hatch, of the same colour
as the background, behind text that overlaps
lines, for plotting purposes. Will this cause a
problem with a submission? A There can be no
pattern or hatch placed on the submitted layers
however, they can be used on other layers. Q I
currently use complex symbols. Do I have to
change the symbols I use for all future
submissions? A No, symbols can be used as long
as they are not placed on any of the 5 required
levels. Q My ATS line work is broken is that
acceptable? A ATS line work on layer 17 is
required and must be clean and unbroken for every
quarter section affected by the surface activity.
Other ATS line work can be placed on layer 9 and
broken as necessary for drafting and snapping
purposes. All ATS line work for all quarter
sections affected by the surface activity must be
included on layer 17. You may choose not to turn
on Layer 17 when creating your paper plots or PDF
file but the linework must be submitted as part
of the CAD submission.

FAQ - continued
Q I include dimensioning in the detail, rather
than on the main plan. Should I include the
detail in my submission? A Details do not need
to be included in the digital submission. Q I
use descriptive names for my layers (AutoCAD)
rather than numbers. How will this affect
submission? A The layer numbers are required to
be used as in the specifications. All files must
be submitted with the correct layer structure.
For AutoCAD users, there is a layer translator
tool that can be used to translate the layer
names to the numbered layers required by
PLFD. Q I currently use a different layer
structure. Do I have to change my layer structure
entirely? A No, as long as the data is
segregated properly, a copy of the file can be
made and the layer structure reconfigured just
before submission. Q My entire design is in
model space (AutoCAD), including the Title Block.
Does this present a problem? A For the digital
CAD submission, only layers 9, 10, 17, 28, and 40
need to be georeferenced and included. Other
information is extraneous and will not be used.
For the PDF file, the design and title block must
be presented as it has been traditionally.
Remember, the PDF file becomes the Plan of
Record. The method for creating it is
unimportant.
PLFD File Submission 27 23 June, 2005

FAQ - continued
Q We use the cadastral mapping files as a
reference base for mapping. Will this satisfy the
requirements for being georeferenced? A Yes,
the March 2005 ATS was created from the Cadastral
Base. Q Will it matter if I georeference and
submit the entire CAD file rather than just the
specified layers? A No however, the
appropriate data must be contained on the
mandatory 5 layers. Q There are instructions
for georeferencing the CAD file in AutoCAD. How
do I georeference my file in Microstation? A
Open the file to be georeferenced and attach the
ATS file to be used for georeferencing. Place a
fence (overlap) around the active file. Fence
Move the active design from the ATS corner to the
corresponding point in the reference file. Fence
Rotate the active file using the 3-point method
with the common point used for movement as the
pivot. Q I use a local coordinate system for
drafting. Will this interfere with the
submission? A Yes, however, after creating your
file make a copy, scale the file and translate
and rotate the file to match the March 2005
coordinates.
PLFD File Submission 28 23 June, 2005
29
FAQ - continued
Q I tied my data to ASCMs. Do I still need to
georeference my data to the ATS? A No. Surveys
tied in to ASCMs do not need to be georeferenced
to the March 2005 ATS. Submitted data needs to be
either aligned with the ATS or tied in to
provincial survey control. Q Will the
Disposition Mapping set be coincidental with the
Cadastral Base and will it be as accurate as the
Cadastral Base? A No, the Government is not
able to manage dynamic data with their present
system, and has therefore requested that the data
be compiled on a frozen snapshot of the ATS. Q
Why are the layers different from the LTO
specifications? A SRD and LTO are separate
entities and have separate approval and
registration processes. Q What if I use the
DDIPS create file and I have not yet created
the PDF file? A The required PDF (and CAD)
file(s) must be created prior to running the
DDIPS application. The DDIPS application will
assemble all three files, PDF, XML and CAD, into
a zipped file.
PLFD File Submission 29 23 June, 2005
30
FAQ - continued
Q I have security concerns about including my
signature in the digital files. Is this a
problem? A Signatures are only required in the
PDF file, which will become the Plan of Record,
and is not required in the CAD submission. Q
When we are registering for the training seminar,
why are we registering with Martin Newby
Consulting Ltd. rather than the Director of
Surveys? A MNC has a service contract with
AltaLIS, who is the operating entity for SDW. SDW
has been requested by the Government to oversee
and manage the Disposition Mapping project. A
