1 Boundaries with Maris Viewing, Editing, and Creating Boundaries

2 Reminders About Maris Autostreet layers are not your live geocode! When you are editing boundaries, you will often want to see nodes How to display your real geocode Go to View > Nodes and Segments to see your actual data

3 What is Maris? The program for editing Geocode, Mapseg, and Boundaries Now, you can edit your Geocode and boundaries in the same program

4 Help The new software has extensive help Try it first if you have a problem or question

5 Documentation Edulog.nt Conference Manual pages 37- 47. Pull a copy from ITRE ftp site ITRE_DM\RESOURCES\Edulognt\Docum entation\ This new document supersedes : Edulog.nt Overview – Chapter 19 Working with Boundaries

6 Maris -Editing and Creating Boundaries Boundaries are polygons that define areas in the map These polygons consist of either new points or use existing geocode nodes as points In Edulog, the main issue in boundaries is which parts of the geocode are inside or outside the boundaries

7 Your Current Boundaries Boundaries are either converted from PTSIII or re-created in a new geocode

8 Viewing Boundaries To view only, go to View > Boundaries

9 Loading Existing Boundaries Boundaries are loaded from the main option You must load a boundary (unprotected ones!) to work with them

10 Post/Protect Boundaries When you associate a boundary with a school it is called “posting” that boundary When a boundary is posted (in Edulog.nt), it automatically becomes “protected” and can’t be edited To edit the boundary, you can either un-post it or make a copy and work with the copy (a safer approach) Once you have the changes made to the copy, you can unpost the original and post to the new boundary

11 The Laws of Boundary Creation Always create boundaries in a counter- clockwise direction No “doughnuts” or holes in boundaries When finished boundaries should not cross over themselves

12 Sample Boundaries-New Points Defining a new area using new points Boundary of all new points Recommendation: If no boundaries exist, make boundary #1 the whole county

13 Sample Boundaries-Free/Snap Points Defining a new area using free points (wherever you want) and/or Snap points (existing nodes in the TIMS geocode) Boundary points That “Snap To” Existing geocode Nodes

14 Important Rules for Making Boundaries Exact Since students and stops are located on segments, the most important aspect of the boundary is whether it contains the correct set of segments This is done by using a combination of new points and existing nodes The boundary defines a set of segments No Students included beyond these nodes

15 Important Rules for Making Boundaries Exact In TIMS, boundaries can be drawn to include only one side of the street, both sides, or excluding everything up to side streets Both Sides Neither Side Northern side only

16 Drawing Boundary Techniques Plateau vs. Saw-tooth

17 Creating a Boundary From Scratch To create a new boundary manually: From the boundaries menu, choose add, then choose manually Click the location of the first boundary point (a dot will appear with a line attached) Click the location of the second boundary point. Notice that a stretchy line is following the mouse pointer

18 Example – Create a Boundary Zoom into the northwest corner of the map as shown Create the boundary as shown Point 1 Point 2 Point 3 NOTE: If you make a mistake while drawing, use the Esc key to remove an added point. (Only works if changes were not saved)

19 Creating a Boundary From Scratch - continued Continue to define the points of the boundary Double-click the location of the last boundary point A dialog box appears asking if you are finished defining points When you answer yes, a dialog box appears for you to name the new boundary. Notice that the system has automatically assigned a number to the new boundary ©Education logistics, 1998… these instructions are from the help system in Edulog

20 Example – Create a Boundary Finish the boundary out as shown Double- click to finish and answer the questions

21 Terms - Kinds of Boundary Points Free points at the exact location of the mouse pointer. Snap points are placed directly on top of nodes Snap points are always located directly on top of a node and are located in the middle of the street

22 Mouse ‘Clicks’ for Drawing and Options Free Point Left Click Snap Point Shift – Left Click Trace Street Ctrl – Left Click Options Menu Right Click Undo Esc Yes, there is an Undo!

23 Add/Edit Mode Add Mode – While you are creating a new boundary Edit Mode – Any time you are working with an existing boundary Things work differently in each mode You can’t get back to Add Mode for a boundary once you have gotten out of it

24 Zooming Always zoom in or out through the right-click menu If you use the mouse outside the workspace to access any button or tool, the add or edit mode will be ended

25 Editing Boundaries Delete points by selecting the boundary, then click on a point. Once it is highlighted, it can be deleted with the delete key Move points by clicking on points in a selected boundary and dragging them with the mouse The “right click” is critical to remember when using this program – It allows you to get back to the function you need, when you need it

26 Editing Boundaries Matching Point-to-Point Example: One boundary has been modified and you now have a gap where an adjoining boundary once met. Solution: In Maris, connect the individual points together. This works well with small areas This boundary to the north should connect and end here.

27 Example - Editing Boundaries 1.Bring both boundaries, the newly modified one and the one that needs to be re-matched up in Maris (Click on Boundaries > Load) 2.Enter the ‘edit’ mode (Click on Boundaries > Edit) then click on a boundary and the boundary points will turn black. Forward = moves it up one layer. Front = moves it to the top when there are several overlapping boundaries. Note: In some instances, you may need to move the boundary ‘forward’ or ‘front’ so that it will be on the top of any other boundaries that may be displayed and overlap in some areas. Just right click on that boundary and select ‘Forward’ or ‘Front’.

28 Example - Editing Boundaries 3.Click on a boundary point (on the boundary that is to be modified) and it should turn red.

29 Example - Editing Boundaries 4.Release the left mouse button (without moving the mouse) 5.Hold down the CTRL key 6.Click back on the red boundary point 7.While holding down the CTRL key drag the red point toward the boundary that you want to trace and it should ‘snap’ to that point. CTRL

30 Example - Editing Boundaries You must repeat this process for each point that you need to move This is the change that was just made If the boundary does not have enough ‘free’ points available, you will need to ‘add’ points, or if there are too many points, you will need to ‘delete’ points.

31 Example - Editing Boundaries (After modification) (Before the modification)

32 Editing Boundaries- The Right Click Once loaded, right- click gives full function menu NOTE: If the full function menu does not appear, then you are not in ‘edit’ mode. Right click on the mouse, select boundaries>edit to get into the ‘edit mode’

33 Editing Boundaries-Add Points Adding points is done with the right- click menu Select the Add Points option, then follow the directions at the bottom of the window to add points to a boundary

34 Editing Boundaries-Snap to Node When drawing a boundary, holding will cause the pointer to “snap” to the nearest node This replaces the “new point” or “old node” option in PTS3

35 Special Edits To finish our discussion of editing and creating boundaries, we will cover three special edits that are used frequently: Tracing Streets Tracing Adjacent Boundaries Distance Boundaries

36 Tracing Streets Tracing streets allows you to include students on one side of the road, but not the other This usually occurs in urban areas, but the center of the street can be a boundary line in rural areas sometimes

37 Tracing Streets To trace a street Press and hold the CTRL key while clicking on the segment you want to trace Continue to hold the CTRL key Create a boundary point at the end of the segment you want to trace Release the CTRL key Maris traces the segment, placing boundary points at each shape point along the street ©Education logistics, 1998

38 Tracing Streets You can move several nodes along a street before you click in this mode, and the system will trace the geocode from the last node If you move too far away from the first node, the path the boundary takes may be unexpected, so don’t go too far in one jump

39 Tracing Adjacent Boundaries The other special editing feature is tracing adjacent boundaries Tracing boundaries is accomplished with the “right-click” menu It is a much simpler process than in PTS3 – the main thing is to read the bottom of the screen

40 Example – Tracing Adjacent Boundaries The blue boundary is an existing boundary The green boundary is being drawn in using regular points and then tracing a street. Stop Here! Start here Trace streets here

41 Example – Tracing Adjacent Boundaries Now the bottom of the green boundary gets traced to match the blue one Right-click and select Add Points Right-click and select the trace boundary option Follow the directions at the bottom to complete the operation Think about direction here

42 Example – Tracing Adjacent Boundaries This should be your resulting boundary

43 Distance Boundaries Boundaries > Add > Auto > Distance Choose Node(s) or Segment(s) Set Options

44 Distance Boundaries Note: The system is only able to place boundary points along existing geocode segments. This may cause problems with the way the system draws some distance boundaries This may call for some manual cleanup of boundaries

45 Distance Boundaries - Example Green Segments should be in the boundary

46 Distance Boundaries - Example The boundary should be manually edited to include the appropriate segments

47 Managing Boundaries There are several things you can’t do in Maris: Copy Boundaries Delete (protected) Boundaries Protect/Unprotect Boundaries Post/Un-post Boundaries Student Tallies/Analysis

48 Managing Boundaries These management functions are accomplished in either Edulog.nt or GeBndPlan or ElPlot

49 Copying Boundaries Open ElPlot Select Boundaries Click on boundary to copy Click on Copy Selected Boundary

50 Deleting Boundaries Open ElPlot Select Boundaries Click on boundary to copy Click on Delete Selected Boundary

51 Protecting/Unprotecting Boundaries Open Edulog.nt Go to Boundary >Set Protection Click on the boundary Select Protect or Unprotect

52 Posting/Unposting Boundaries Also in Edulog.nt Go to Boundaries> Post for Eligibility Select the school Pick the type

53 Posting/Unposting Boundaries To post: click on a boundary on the left Select Post

54 Posting/Unposting Boundaries To Un-post: click on the posted boundary Select Un- Post
