Use Agricultural Parcel Analysis

In this topic, you’ll learn how to use the solution by assuming the role of a user and performing the workflows below.

Note:

Use your organization's data or configured apps to follow these workflows.

Create an agricultural review

Local assessors have a statutory responsibility to discover, list, and value agricultural parcels. Since most agricultural parcels are assessed according to their size, land use, and soil type, a comparable sales approach is not appropriate. Using the Agricultural Parcel Analysis app, the assessor's office can visualize agricultural parcel characteristics, define various appraisal units, and understand soil composition.

Assessment units are defined as a single parcel, a division of a parcel, or group of parcels of land evaluated specifically for their use in agriculture. This type of appraisal focuses on the land's capability to produce agricultural products such as crops, livestock, and other resources. The valuation methods for agricultural appraisal units often consider factors such as soil quality, water availability, climate, and current use in agricultural production.

There are several methods to add agricultural parcels to the review queue. The request may come from the public through the Agricultural Review Request app, your GIS team may upload a set of parcels directly into the queue, or an individual assessor may need to add one record at a time.

You will assume the role of an assessor. When needed, an assessor can create a record to add to the agricultural property review queue.

1. Sign in to your ArcGIS organization and browse to the Agricultural Parcel Analysis app.
2. From the item page, click View.
3. At the top of the page, click the New Review button.
4. Select a parcel on the map to create a review.
5. Search for a parcel by the parcel ID or address, or zoom to a location and select a parcel.
6. Once a parcel is selected on the map, complete the form on the right side of the page.
7. Click the Submit button to submit the form that adds this parcel to the review queue.

Submit public review

When enabled, the Agricultural Review Request app can be used by property owners to request an agricultural exemption request. This app can be embedded into your website or used as a stand-alone app.

You will assume the role of a citizen. You want to request an agricultural review of a property.

Note:

This workflow is optional and doesn't need to be completed in order to work with the solution.

1. Browse to the Agricultural Review Request app.

Note:

Optionally, you can embed the Agricultural Review Request app in a website.

2. Select a parcel on the map to create a new review.
3. Search for a parcel by the parcel ID or address, or zoom to a location and select a parcel.
4. Once a parcel is selected on the map, complete the form on the right side of the page.
5. Click Submit to submit the form, which creates a record in the agricultural analysis queue.

Assess agricultural information

You will assume the role of an assessor. As an assessor, you want to explore the agricultural parcels in the review queue. You can view the information for each review and explore associated data to provide context and enable your decision-making process.

1. Verify that you are signed in to your ArcGIS organization and browse to the Agricultural Parcel Analysis app.
2. From the item page, click View.
3. Explore the parcels in the review queue, view the information for each review, explore associated data.
4. On the left side of the page, view indicators of the review status for each record.
5. Further down, view a list of the records in the queue. Optionally, use the filters or sort tools to narrow down the list of records in the queue.
6. Select a record in the queue list.

   The map will zoom to the selected parcel and the parcel details will display.

7. Use the map tools to explore the data further, turn layers on and off, switch basemaps, or measure on the map.
8. If the parcel does not meet the agricultural qualifications, proceed to Update Review and set the status to Completed Rejected.
9. If new land use boundaries need to be created for the parcel, proceed to Create agriculture appraisal units section.

Create agriculture appraisal units

You will assume the role of an assessor. As an assessor, you will create and modify land use boundaries in order to create agricultural appraisal units that serve as inputs to the spatial analysis process. Using aerial photos, you will draw land use boundaries directly on the map. All edits are automatically saved and there is no undo option.

Create an appraisal unit

To create an appraisal unit, complete the following steps:

1. Verify that you are signed in to your ArcGIS organization and browse to the Agricultural Parcel Analysis app.
2. From the item page, click View.
3. Once you have selected a parcel from the queue, the map will automatically zoom to the parcel location.
4. Use the Editor panel to create land use boundaries on the map.
5. Click a land use type.
6. Click a starting point on the map to start drawing the boundary for the selected land use type.
7. Click once on each vertex of the land use boundary you want to create.

   Snapping to the parcels and other land use boundaries will guide you in creating accurate data.

8. Double-click the last vertex to complete your boundary.
9. Click Create.

   Your new boundary is now completed.

10. To continue creating additional land use boundaries of the same type, repeat steps 4–9.
11. To create a different land use type, click the Back arrow and select a new land use type from the Agricultural Land Use list. Then, repeat the steps 4–9.

Modify existing appraisal unit

To modify an existing appraisal unit, complete the following steps:

1. Verify that you are signed in to your ArcGIS organization and browse to the Agricultural Parcel Analysis app.
2. From the item page, click View.
3. In the Editor panel, click the Select tool, and select the land use boundary on the map you want to modify.
4. To change the land use type, click the drop-down arrow next to the exiting land use code and select a different land use.
5. To reshape the land use boundary shape, click one of the exiting boundary lines. Drag the existing vertex points (orange dots) by clicking and dragging, and add a new vertex by clicking the mid-point of the lines (white circle).

   You can move the new vertex as needed.

6. To move the land use boundary shape, hover over the boundary until a four-sided arrow appears.
7. Click and hold and move the entire boundary to the desired location.
8. Click Update to save changes.

Delete appraisal unit

If you make a mistake you can delete a boundary and start over. To delete an existing appraisal unit, complete the following steps:

1. Verify that you are signed in to your ArcGIS organization and browse to the Agricultural Parcel Analysis app.
2. From the item page, click View.
3. In the Editor panel, click the Select tool, and select the land use boundary on the map you want to delete.
4. In the Editor panel, click Delete twice to permanently delete the feature.

   Caution:

   This action cannot be undone.

Update agricultural review

You will assume the role of an assessor. After you create or modify the appraisal units, you will need to update the review status and add any notes if appropriate.

1. Verify that you are signed in to your ArcGIS organization and browse to the Agricultural Parcel Analysis app.
2. From the item page, click View.
3. Select a record from the queue list and click Update Review.

   This will open a new window with a form to review and edit information.

4. Change the status as needed:
   • Needs Review—This is the default status when a record is created and indicates the record needs to be assessed.
   • Land Use Created—Set this status after new land use boundaries have been created.
   • Completed Soils Calculated—Once the soil analysis tool runs successfully, it will automatically change the status to Completed Soils Calculated.
   • Completed Rejected—If the parcel does not qualify for an agricultural classification select this status and add notes as to why the parcel does not qualify.
5. Optionally, add notes to the internal notes section or change any of the other information as needed.
6. Click Update to save your edits.

Compute agricultural parcel information

Most agricultural parcels are assessed according to their size, land use, and soil composition. Now that the various appraisal units have been defined, you must perform a spatial intersection analysis that identifies the soil composition for each appraisal unit. In this workflow, you will learn how to perform a spatial intersection and update the soils table when necessary.

You will assume the role of a mapping technician. You are asked to use the Agricultural Parcel Analysis Notebook app that uses the AgriculturalAnalysis layer, the AgriculturalLandUse layer, and the USDA soils layer from ArcGIS Living Atlas to perform a spatial analysis intersection, aggregate the results, and update the AgriculturalSoilValues table.

The notebook runs on all agricultural analysis parcels with a status set to Land Use Created.

Note:

You must be assigned a role of Administrator or custom role, which includes the privilege to create and edit notebooks, which allows you to run Notebooks to complete the following steps.

1. Verify that you are signed in to your ArcGIS organization and browse to the Agricultural Parcel Analysis Notebook notebook.
2. From the item page, click Open Notebook.
3. Click Cell drop-down menu and choose Run All.

   The notebook will run and a new dialog box will appear.

4. Optionally, turn on the acres tolerance. Review the internal notebook information for more details about this option.

   By default, the acres tolerance is turned off.

5. Click the Calculate Agricultural Acres button.
6. Review the feedback dialog box to view the analysis processes.
7. Close the notebook.

   You do not need to save it.

8. Return to the Agricultural Parcel Analysis app, filter by a parcel ID of a record that you wanted to update, and click the record.

   If the tool ran as expected, the soil values display with the aggregated acreage totals for each parcel based on land use and soil type. If the tool failed, or if there was an error, view the Analysis Tool Notes field to determine possible issues for the failure. The land use boundaries may need to be refined to remove digitizing errors.
