Developing
Color Location Maps in MicroStation v8
|
|
|
|
| Before you begin |
|
Location maps are being used on larger projects to
show the area surrounding the project. Typically, they include roadway,
hydrology, rail, and town boundaries. They may also include points of
interest in the project area.
|
|
| Summary of the
process |
- Create a new drawing to contain the location map
- Attach GIS reference files
- Fence the desired project area
- Copy to the new drawing
- Edit details
- Add titles, scale, etc.
|
|
| Create the new drawing |
- Start MicroStation and create a new drawing to
contain the completed map. The name will typically be in the form 12345LLC.DGN.
- Attach the alignment drawing as a reference to
this new drawing and issue the "Fit View" command to display the
project area.
- Attach m:\cadd\GIS_to_Microstationv8\all.dgn
as a reference file. In the Attach
Reference Settings dialog box under Nested Attachments change
No Nesting
to
Live Nesting and Depth : 1. (Ignore the warning about
the file location not being part of the reference file path. These files are
only temporarily attached to create the map data within the LOC file.)
- At this point you should see the data from the
GIS maps included in the view.
- Turn off the alignment reference.
- Create a fence around the area to be displayed
on the location map.
- In the reference file manager, select the Clip
Boundary option from the Tools menu. Make sure the Method is
set to Fence.
- With the all.dgn file selecting in the reference
file manager, select the Merge Into Master option on the Tools
menu. This will copy the elements within the clip boundary into your current
drawing.
- The GIS drawing will be detached during the copy
process.
- Save the file.

| Editing the
Drawing |
|
The new drawing will need to be edited before it
will be acceptable for display purposes. Editing will include changing the
levels, colors, and line weights of many features. Text for road names, river
& pond names, and town names will need to be added or modified. Some of this
may have been included in the GIS data.
After the GIS data has been edited some additional
details should be added. This includes:
- Project name and number
- Scale bar
- North arrow
- Highlighting of proposed work area
- Fill color for ponds and large rivers
Currently, there are no standards for these
drawings. Some suggestions are listed below. Each of these items should be on a
different level.

Line weights, linestyle scales and text heights will vary depending on the scale of
the final plot. Some recommendations are provided. These are based on a
1"=500' (1:6000) scale drawing. You should alter these values as necessary for your
drawing.
