Tutorial: Creating new parcels in the fabric
This topic applies to ArcEditor and ArcInfo only.
In this exercise, you will explore the various methods of creating and adding new parcels to a parcel fabric. You can create new parcels in existing plans or create new plans. Parcels can be traversed in the parcel traverse environment or can be built from a network of connected line work in the parcel construction environment. You will also learn how to enter new parcels into an empty fabric.
Creating a new plan
In this exercise, you will create and add a new plan to an existing fabric of parcels and plans.
- Open ArcMap and load the ParcelEditing map document (ParcelEditing.mxd) from your \ArcTutor\Parcel Editing\ folder.
- Make sure the map display is zoomed to the parcel editing overview area. Click the Bookmarks menu and click Parcel Editing Area.
- Click the Parcel Editor arrow on the Parcel Editor toolbar and click Start Editing.
- Close the Create Features window.
- Make sure the parcel fabric edit mode is set to automatic. Open the Parcel Editor Options dialog box (Parcel Editor > Options) and choose Automatic under Edit Mode on the General tab. Click OK.
- Click the Parcel Editor arrow on the Parcel Editor toolbar and click Plan Directory.
- Click Create Plan to create a new plan.
- On the Plan Properties dialog box, click the General tab and enter a name new for your new plan. For this tutorial, type Map 9000 as a plan name. You can also optionally enter a plan description.
- Click the Record Format tab to specify the units that you will be working with in this plan.
- Leave the default for Area Units.
- Optionally, click the Circular Curve Parameters and Circular Curve Direction drop-down lists to specify circular curve parameters for this plan.
- Click the Corrections tab on the Plan Properties dialog box.
- Click Apply on the Plan Properties dialog box to apply your changes.
- Click the Attributes tab.
- Click the drop-down list next to the Accuracy field and choose accuracy level 3 - 1908 to 1980.
- Click OK on the Plan Properties dialog box to create the plan and complete the exercise.
- Click Parcel Editor > Stop Editing to stop the edit session. Make sure to save your edits.
You will be able to identify which curve parameters a plan uses by looking at the curve dimensions on the plan. Curve dimensions are sometimes displayed in a curve table for labeled curves on the plan.
You can add other attributes to the plans table, and these attributes will become available on the Attributes tab on the Plan Properties dialog box.
Creating feature templates
Before creating a new parcel, you will create a feature template for fabric parcel polygons. Feature templates define all the information required to create a new feature, such as the attributes that are populated with the feature and the layer that the feature is stored in. Feature templates can be added at any time during editing and can be based on existing layer symbology such as parcel line type.
You will create a feature template for parcels created in the plan Map 9000.
- In ArcMap, click the Catalog Window tool on the Standard toolbar to open the Catalog window.
- In the Catalog window, navigate to the location of your tutorial data, right-click the parcel fabric named FABRIC, then click Properties.
- On the Parcel Fabric Properties dialog box, click the Fabric Classes tab and choose Parcels from the Classes drop-down list.
- On the field list grid, scroll down to the first empty Field Name row to type a new field name. Type PlanName as the field name and set Data Type to Text.
- Click OK to add the field and close the Parcel Fabric Properties dialog box.
- Close or dock the Catalog window.
- Back in ArcMap, click Parcel Editor > Start Editing to start an edit session to create the feature template. Close the Create Features window.
- In the Table Of Contents window, right-click the parcels sublayer, point to Edit Features, then click Organize Feature Templates.
- Click the New Template command.
- With the Parcels sublayer checked, click Finish on the Create New Templates Wizard dialog box.
- Right-click the second Parcels template in the list and click Properties.
- On the Template Properties dialog box, rename the template Plan_Map9000. Type 24 in the Type field, type 3 in the Accuracy field, and Map 9000 in the PlanName field.
- Click OK to apply the template properties. Close the Organize Feature Templates dialog box.
- Save the edit session to complete the exercise.
New fields can only be added outside an edit session in ArcMap.
Creating a new parcel in automatic edit mode
In the parcel fabric, you can either create and edit parcels directly in the map in automatic edit mode or create edit parcels in fabric jobs in manual edit mode. In this exercise, you will create a new parcel in automatic edit mode.
- In ArcMap, click the Parcel Editor menu and click Options to open the Parcel Editor Options dialog box.
- Under Edit Mode, make sure Automatic is selected.
- Under Parcel view behavior, click the Automatically zoom to extent of parcels when editing option.
- Click OK to apply your changes and close the Parcel Editor Options dialog box.
- If necessary, start an edit session and close the Create Features window.
- Click the Select Parcel Features tool on the Parcel Editor toolbar, right-click parcel 97 in the map, then click Unjoin.
- Zoom to the area where the new parcel will be added to the fabric layer.
- Click Parcel Editor > Plan Directory to open the Plan Directory dialog box.
- Right-click the plan you created in the exercise above (Map 9000) and click New Parcel.
- Click anywhere in the map to add the starting point of the parcel traverse.
- On the Parcel Details dialog box, make sure the Properties tab is active.
- Click the Template button and choose the Plan_Map9000 template on the Select Feature Template dialog box. Click OK.
- Type 97 for the parcel Name field.
- Click the Lines tab on the Parcel Details window to begin entering the parcel traverse.
- On the Lines grid, click the Template field and choose the Frontage template for the first line in the parcel traverse.
- Type 32-30-0-2 (SE quadrant bearing shortcut) in the Bearing field and 69.00 in the Distance field. Press ENTER to create the first line.
- Type a Bearing value of 57-30-0-3 (SW) and a Distance value of 114.00 for the second traverse line.
- Type a Bearing value of 32-30-0-4 (NW) and a Distance value of 69.00.
- For the last traverse line, type a Bearing value of 57-30-0-1 (NW) and a Distance value of 114.00*.
- On the Parcel Details dialog box, click the Keep changes to parcel data and join command to save the parcel and begin joining the parcel to the fabric.
- With the Join Parcel dialog box open, drag the new, floating parcel and position it such that join lines can be easily established.
- Click the Create Join Link Using a Dragbox Around a Fabric Point and a Join Point tool on the Join Parcel dialog box and drag a box around the joining parcel's top left point and the corresponding fabric point to create your first join link.
- Repeat step 22 to join the joining parcel's bottom right point.
- Click Auto Join on the Join Parcel dialog box to detect the remaining join lines.
- Click OK on the Join Parcel dialog box to complete the join.
- Save the edit session to complete the exercise.
If the Parcel Explorer window is not visible, click the Parcel Explorer Window tool on the Parcel Editor toolbar.
To delete a parcel instead of unjoining it, right-click the parcel in the map and click Delete. You can also delete unjoined parcels by right-clicking the parcel in the Parcel Explorer window and clicking Delete.
If you do not want to work with plans, you can right-click the <map> plan, which is a system default plan. All parcels will simply have <map> as their associated plan.
If the Parcel Details window is not visible, click the Parcel Details tool on the Parcel Editor toolbar.
You can also click an existing point in the map as your starting point. If you snap to existing points in the map, you will still have to join and connect the parcel to the fabric once it's created.
Notice that the from- and to-points are automatically populated for you unless you edit them. If you edit a from- or to-point, you need to make sure to check and edit the remaining from- and to-points in the traverse lines grid.
You can also click the Keep changes to parcel data command to save the parcel as unjoined. In the Parcel Explorer window, you can right-click the parcel and click Join to join the parcel to the fabric at any time.
Parcel joining is an interactive process where the parcel points of a floating parcel or group of parcels are matched with their corresponding points in the parcel fabric.
You can also use the Construction tool to manually snap on the joining parcel's point and snap on the corresponding fabric point to create a join link.
Join residuals are computed from a transformation between the joining parcel's points and the corresponding points in the parcel fabric. If only two points are joined, a Helmert transformation is used. If more than two points are joined, a least-squares transformation is used. Each time another point is joined, join residuals, scale, and rotation are recalculated.Join residuals are an indication of how well the joining parcel fits with the surrounding fabric.
You can click Close on the Join Parcel dialog box at any time during the join process to cancel the join. The parcel is then saved as unjoined and is listed as an unjoined parcel on the Parcel Explorer window.
Creating a new parcel in manual edit mode
In manual edit mode, parcels are created and edited in fabric jobs. Jobs are tracked in the job book and can be saved and reopened at any time. In this exercise, you will create the same parcel that was created in the above exercise, but this time you will work in a fabric job.
- On the Parcel Editor Options dialog box, choose the Manual edit mode. Leave View and edit parcels individually in a local coordinate system unchecked.
- In an edit session in ArcMap, click the Select Parcel Features tool on the Parcel Editor toolbar.
- Drag a box to select the parcels shown in the graphic below that will be part of the job. When creating a new parcel in a fabric job, the appropriate reference parcels should be added to the job so that the new parcel can be joined to the fabric layer.
- Click the Parcel Editor menu and click Modify to open the parcels in a job.
- Using the Select Parcel Features tool , right-click parcel 97 and click Unjoin.
- Click the Create A New Parcel In A New Plan tool on the Parcel Editor toolbar.
- On the Parcel Details dialog box on the Properties tab, click the Plan button, choose Map 9000 on the Plan Directory dialog box, then click Set as Active Plan.
- Click the Template button, choose the Plan_Map9000 template on the Select Feature Template dialog box, then click OK.
- On the Property Details dialog box, type 97 as the parcel name.
- Click in the map to add the starting point of the parcel traverse.
- Follow steps 17 to 25 under the Creating a new parcel in automatic mode exercise to create and join your parcel.
- Once you have joined your new parcel to the surrounding job parcels, click Parcel Editor > Finish Job to post your job changes back to the parcel fabric layer.
Job workflow commands, such as Modify and Finish Job, are available under the Parcel Editor menu when the fabric edit mode is set to manual.
You can also open an empty fabric job. With no parcels selected, click Parcel Editor > Modify. You would create an empty fabric job when adding parcels to an empty parcel fabric.
You can also formally create a job with a name and description by clicking Parcel Editor > Create Job. On the Create New Job dialog box, you can specify the parcels that will be edited as well as the surrounding reference or job parcels.
To reopen the job, click Parcel Editor > Job book and double-click the job listed on the Job Book dialog box.
