FARMS

Custom Reporting Service

The Farm and Ranch Management Support (FARMS) system is a user-friendly interface from OpenET that makes accessing and using ET data simpler than ever—on any device, including mobile. FARMS offers customizable report generation and powerful insights to streamline agricultural planning. We invite you to explore its features, share your feedback, and help us shape a platform that truly meets the needs of the farming community. Join us in taking a data-driven approach to agriculture and discover what FARMS can do for you.

Step 1: Log in

When you visit FARMS, you’ll be prompted to sign in to your OpenET account. After logging in, you’ll be automatically redirected back to the site.

If you haven't visited in a while, you will need to log in.

An API key is required to use FARMS. Once you have generated an API key o your user profile, you will be able to access the reporting features of FARMS. Make sure to keep your API key private —treat it like a password.

Step 2: Define your region of interest

Note: All files uploaded to OpenET are automatically reprojected to EPSG:4326 (WGS84).

When you first visit the site you will be prompted to add a set of boundaries. Boundaries can be either uploaded, drawn, or selected from OpenET's geodatabase.

This modal will appear if you have no saved boundaries.

Any spatial region of interest you define must comply with the area and polygon limits of the FARMS service. These are different from individual account quotas and apply to all users.

Limit	Amount
Max Area	500,000 acres
Max Polygon Count	500

Below is a table outlining the three methods you can use to define boundaries in FARMS.

Upload, draw, or select.

Upload Shapes

Upload either a geoJSON file or a zipped shapefile, which will automatically be reprojected to EPSG:4326. If you’re using a shapefile, make sure your zipped folder includes at least the .shp, .dbf, and .prj files. Avoid spaces or special characters in file names and only include one set of shapefiles per folder. Each polygon in your shapefile must have a unique identifier attribute, which you’ll select manually during the upload process. Hit the Save Shapes as Dataset button for them to show up in your View Boundaries tab.

Draw Your Own

FARMS includes a drawing tool that lets you create and modify shapes. Each polygon is automatically assigned an "ID" attribute, which increments from 1. Once done, hit the Save Shapes as Dataset button for them to show up in your View Boundaries tab.

Select Existing

You can also select from the existing fields in the OpenET field boundary dataset. Each polygon is automatically assigned an “ID” attribute based on the existing field’s identifier. Once done, hit the Save Selected Shapes as Dataset button for them to show up in your View Boundaries tab.

Select from over 4.5 million pre-defined polygons.

Step 3: Build your report

After defining your spatial region, click Create Report to generate a new report. You can then specify the time period, interval, and model-variable combinations. Be sure your chosen time range falls within the quota intervals listed in the table below. These intervals ensure there are enough cloud-free satellite observations and sufficient historical data for accurate reporting.

Limit	Minimum Amount	Maximum Amount
Daily	30	60
Monthly	3	120

Create report page.

After saving the report, you’ll be taken to a temporary page while the report is generated. This page will automatically refresh upon completion, but you can close it and return later if you prefer.

Step 4: View & Download

Once a report is complete, you can select multiple fields to add them to the chart. Each field is color-coded, and you can deselect it by clicking again. To download the report’s data as a CSV, click the download icon. The CSV will include columns such as time, id, and area_acres, along with any relevant volume calculations in acre-feet (based on your selected variables). If you prefer a PDF, click the printer icon and use your device’s standard print functionality for the field of interest.

Step 5: Make Public

By default, all FARMS reports are private. They can be password-protected under the settings icon for secure sharing. If a report is set to public with the toggle icon, anyone with the shared link can access it—but they must have an OpenET account to view it.
