Redistricting
Following is a list of the items in the MapEdit
pull down menu along with a brief overview of the functionality
that each tool or command option offers.
| 1. Change Name |
From a single dialog box the user may change
the name of a segment feature for a single TLID or for all
TLIDs with the same Reference Number. For roadway features
denoted by an “A” type Census Feature Classification
Code (CFCC), the user may edit a primary name and up to 5
alternate feature names.
|
| 2. Change Attributes |
Permits the user to have direct edit control over the left
and right address information for a segment (to and from addresses
and 5 digit zip codes) and the CFCC for that segment. This
tool is used on a single TLID at a time.
|
| 3. Flip Record |
Provides the user with the means to reverse the line direction
for a road segment thus converting the line to a forward encoded
segment for making it easier to edit address ranges.
|
| 4. Distribute Addresses |
Provides two methods of assigning address ranges to multiple
road segments (Proportionate and Unit Length).
|
| 5. MultiUpdate |
Assists the user to update the name, left and right zip
codes, CFCC and Revert Graphics for a group of selected segments.
For roadway features denoted by an “A” type Census
Feature Classification Code (CFCC), the user may edit a primary
name and up to 5 alternate feature names.
|
| 6. Add Segment |
The user can add a new line representing any feature within
the TIGER system. MapEdit presents the operator with a dialog
box for entering the name and other attributes for the newly
created segment.
|
| 7. Trace |
Assists the user to keep track of edits to the geometry
of line work through a change in line symbology consistent
with the specifications set through the Preferences menu option. |
| 8. Create Intersection |
Every time the user adds a new linear feature (i.e. street
or road, railroad, airstrip, creek, stream, etc.) and it intersects
with an existing line, an intersection must be installed unless
it is coincident with an existing intersection. MapEdit performs
this very efficiently, even to the point of prompting the
user for attribute information for the two new segments created.
|
| 9. Shape Point |
There can be 9,990 shape points for a single TLID. With
this tool the user can create a new shape for a selected TLID.
This can result in the addition of shape points, deletion
of shape points all transparent to the end user.
|
| 10. Node Combine |
Allows the user to remove segments that create jogs at intersections
that should be clean through streets. |
| 11. Node Split |
Allows the user to remove segments that create jogs at intersections
that should be clean through streets. |
| 12. MDN |
Is a simple toggle between the setting “Move Duplicate
Nodes in the Same Layer or None of the Layers”. If two
or more lines intersect at the same location they are said
to share a node. With MDN on, the user can select a line and
move the shared node and all of the lines will move with the
first line. This is also referred to as rubber banding.
|
| 13. Construction Point |
This command allows the user to snap a point to a line.
|
| 14. Retire TLID |
In the TIGER system, TLIDs do not get deleted, they get
retired. This tool allows the user to tag an object and MapEdit
will assign a standard CFCC value that indicates the new status
of the line.
|
| 15. Table Maintenance |
Consists of a group of submenus that provide access to
MapEdit functions which manage files as opposed to manipulating
individual or groups of objects in a table. Following is a
list of the items and a brief overview of the functionality
represented by this menu group.
Save Tables will save multiple tables relieving
the user from the need to perform multiple saves.
Revert Tables will revert multiple tables
relieving the user from the need to perform multiple revert
table commands.
Pack Tables will pack multiple tables relieving
the user from the need to perform multiple packing operations.
TIGERUS QCis a set of diagnostic tools. These
tools will make it easier to complete the task of creating
the best enhanced TIGER/Line File possible. Following is a
brief description of each of the menu items:
Missing ZIPCodes will create a file that
contains a list of records that are missing a 5-digit ZIP
Code.
Duplicate Addresses operation will generate
a file that contains a list of records that have duplicate
or overlapping addresses for both primary and alternate feature
names.
Check Snap operation will generate a map
table of points that identify the end points of lines that
are not connected to an adjacent line, but fall within a user
specified snap tolerance.
Intersection Points will build a table of
points that are snapped to the intersections of the segments
within a table of linear features (i.e. lines and polylines).
Compact Name List operation is designed to
eliminate names that entered into the TIGERUS database and
subsequently modified, leaving the initial name unused.
Degenerate Objects will analyze the contents
of TGR1 for zero length line objects and present the user
with a table of points that mark the location of the objects
to be repaired.
Duplicate GeoPoints detects multiple occurrences
of records and reduces the set to one, additionally. it creates
a list of records that have duplication of the three fields
used for geocoding.
TIGER In will import TIGER/Line Files into
a project for purposes of editing with the MapEdit
and GeoPoints.
TIGER Out will export the current database
contained in a project generating enhanced TIGER/Line Files.
An option to run Build Layers will generate map data from
these enhanced TIGERs.
Build Layers accesses the integrated
Universal TIGER Translator (UTT) that converts either
the original or enhanced TIGER/Line Files into mapped layers
for day-to-day use.
Revert Graphics will restore the symbology
of a file that has been edited with Preferences on to the
original styles.
TileMaker is a utility used to divide a TIGER
database into smaller units of geography or restore the units
to a single database. These two functions are performed with
the Create Tiles and Combine Tiles
menu options. Because of the special nature of this
function, the instructions for the use of TileMaker are reserved
for a separate chapter at the end of this manual.
|
| 16. Project |
The Project menu options create and manage directories
and files. A MapEdit database consists of
many directories and files. For the user’s convenience
the database is managed as a project. Following is a brief
overview of this functionality.
Create allows the user to register and create
a project.
Add allows the user to register an existing
project.
Rename allows the user to rename a registered
project.
Delete allows the user to remove a project
from the system.
|
| 17. Setup |
To initiate a work session with an existing project, the
user goes through Setup. This feature allows the user to select
a project. For projects that have been tiled, the user can
also specify the individual tile.
|
| 18. Preferences |
Allows the user to change the graphical representation
for features that are edited, verified, or node combined.
Also, permits specifying the number of feet in a unit for
incrementing addresses in Unit Length addressing.
|
| 19. Exit MapEdit |
This option exits MapEdit and removes it from the MapInfo
Menu Bar. To get MapEdit back the user must launch MapInfo
from the MapEdit Icon or execute the Tools>Run MapBasic
Application.
|
| 20. About MapEdit |
When the user selects this menu item, a dialog box displays
the version and serial number of the active copy of MapEdit.
