Upon logging in, you will view the Plan
This area of the website is for managing the redistricting plans
available to you to edit (if logged in with an account) or view (if
visiting as a guest). In the redistricting world, a plan
complete set of districts for a state or locality. You are not required
to create a complete plan for all the districts, you could, for example
create a plan that has only a single district. We treat all partial or
complete plans the same.
must select a plan to edit before you can start mapping. As you look at
the Plan Tab, you will notice that there are four numbered
steps that you need to take to start drawing your first map.
- Select District Layer
- Select Plan Type
- Select Plan
- Name your new plan
We will walk through these four steps in turn, below.
Action 1. Select Legislative Body
There are two types of layers that you can draw, legislative bodies and communities.
web site administrator will set up one or more legislative bodies for
you to draw districts for. For a typical state, the following
legislative bodies will be available.
- Congressional districts
- State legislature, upper chamber districts
- State legislature, lower chamber districts
administrator may make other legislative bodies available for editing.
For example, if configured for local redistricting, county supervisor,
city council, or school districts may be available.
administrator configures these legislative bodies for you so you
can get started mapping without having to set parameters for each
legislative chambers' districts, such as the ideal population size for
the districts and the target number of minority-majority districts. Only
administrators have the ability to change the available legislative
Community maps are different from legislative districts in that criteria such as equal population are not applied to communities. You can draw essentially an unlimited number of communities, however, communities cannot overlap one another. If you wish to create overlapping communities, you must do so by creating separate community maps.
Action 2. Select Plan Type
The next step is to select a type of plan to edit. There are four different types of plans that you can interact with.
plans are pre-generated plans that are provided by the administrator.
They are intended to be recommended starter maps. These may be the current plan, a blank plan with no geography assigned
to a district, or any other plan that the administrator may choose to
designate as a template.
- Shared plans are plans that you or other users have shared that are available to everyone to view or make a copy of and edit.
- My Plans
are plans that are private to you, and may be only edited and viewed by
you. (Any plans that you have shared are also in your list of plans.)
- Upload Plans
are plans that are generated by other redistricting software, such as
those posted by a legislature or redistricting commission, that can be
loaded for you to view, edit, and share.
If you click on
Temple, Shared or My Plans, the list of plans in the Action 3. Select
Plan will change accordingly to show you the available plans in each
You can upload plans generated from other redistricting software, such as those produced by commercial vendors. These files must
follow a special format. There are three important components to this
format, the format of the records, that the file have an extension
ending in .csv, and that the file must be zipped.
First, the records must conform to a special format. Here is an example of how the records must look:
The first 15 characters is a unique identifier for each census block. (For more information about census data, see here).
It is a concatenation of the state, county, tract, and census block
codes. (Tip: these codes must be in string format. If they are in a
numeric format, leading zeros may be truncated. If you load this
information into another file, be careful to preserve this unique
identifier as a string.)
OPTIONAL: a third comma delimited field can be added to each line that identifies the number of seats assigned to a district. This is for use in states where the software has been configured to support multi-member districts.
A comma separates the census block identifier with a district code, the district that is associated with each census block.
file must have a .csv extension for the file name. For example, the
file name "foo.csv" is acceptable. The extension .csv is a common naming
convention for comma separated files.
Third, the file must be zipped, or compressed. There are many free programs that zip files.
There are six steps to upload a plan.
- Select the Upload Plan tab to view the upload dialogue boxes.
"Browse..." to point the software to the file you wish to upload. This
will open a dialogue box that will aid you to locate the file.
- Select the legislative body you wish to upload a plan for.
- (Optional) provide your e-mail so that an e-mail may be sent to you when the upload is complete.
- Give your plan a name, in the box located in the lower right corner.
- Press "Start Drawing".
will take a few minutes for the software to load the plan. The amount
of time will depend on a number of factors, including how many other
people are using the software. If for some reason you do not receive an
e-mail, check back in a few minutes to see if your plan shows up in the
"My Plans" list. You can work on another plan while the plan is being
are two methods to download a plan. The first method is available on
the Step 1. Plan tab and the second method is on the Step 4. Share tab.
Method 1, from the Step 1. Plan tab.
a plan is selected (see Action 3. Select Plan, below), a "Download"
button will be visible. Click on this button and the software will
generate a file in the same format as described in the Upload Plan
It may take the software up to a few
minutes to generate the requested file. Once a file has been requested
once, it is cached and should be available for download immediately when
subsequent requests are made. When the file is ready for download, a
dialogue box will open guiding you on where to save the file. Method 2, from the Step 4. Share tab.
A file for download may also be requested from the Step 4. Share tab by pressing the "Request File" button.
Action 3. Select Plan
plans that are available for editing are displayed in the Action 3.
Select Plan area. The name of the plan, the author, and the last editing
date/time are displayed. For "My Plans" a check box is also displayed
identifying if a plan is a shared plan, visible to everyone.
Navigating Lists of Available Plans
clicking on the the Name, Author, and Last Edited headers, you can sort
the plans available to you accordingly. (You may also sort by shared
status for My Plans.) If there are many plans, navigation buttons at the bottom of the list of plans will be available. Clicking ►> will move your forward (or backward) one page of plans, Clicking ►|
will move you to the end (or beginning) page of plans. You may also
enter a page number and press return to go to that page of list of
You may search for a plan by entering the search string into the text
box in the upper right of the Select Plan area and pressing return.
Action 4. Name your new plan/Start Drawing
If you have selected a Template
plan, you must name your plan before you can continue.
To do so,
- Enter the name you wish to call your plan in the box in the lower right hand corner.
- Press "Start Drawing" to begin map editing.
If you have selected a plan in the My Plans
list, you have already
given the plan a name so you do not need to do this step. You will be
presented with two options, to edit the plan and to make a copy.
To edit the selected plan
- Select the "Edit Selected Plan" radio button
- Press "Start Drawing".
It is possible to make a copy of a plan that is in the My Plans
list. You may find this useful if you are at a point in creating a plan where you want to explore different options.
To do so,
- Select a plan from the "My Plans" list.
- Click the radio button "Copy and Save Selected Plan"
- Name your new plan
- Press "Start Drawing".
Edit Plan Description
you select an existing plan from the plan list, additional information
in the Plan Details area will be available describing the plan: the
owner, the time stamp of when the plan was last edited, if it is shared,
the number of districts in it, and a "Description." If a plan is owned
by you, you may edit the description by clicking the "Edit Details"
button. You can then enter or modify text in the description box. When
satisfied with your new description text, click the "Save" button that
will appear after you clock "Edit Details".
