AgriSense, Crop Trend Analysis, and some Climate historical queries run on Google Earth Engine (GEE). SINAG does not share a platform-wide GEE login. Each user (or office) uploads their own service-account JSON key. Until that key is linked, those tools stay locked.

What you will create

• A Google Cloud project with the Earth Engine API enabled
• A service account with Earth Engine access
• A downloaded JSON key for that service account
• Registration of the service-account email in the Earth Engine service-account list

1. Google Cloud project and Earth Engine API

1. Search for Google Cloud Console

   

   Search for Google Cloud Console in your browser and click Sign-in in the search results.

2. Create or select a project

   

   Locate the Project dropdown menu and select New Project or Select Project.
   You can use an existing project if your institution already has one, or create a new project (for example sinag-gee-office).
   Note the Project ID; SINAG stores it from the JSON key after upload.

info

Skip the next steps and proceed to the next section if you have already registered your project to Earth Engine.

3. Register the project to Earth Engine

   Go the Search Bar and type Earth Engine and select Earth Engine from the results. After that, you should be able to see the Earth Engine dashboard. Navigate to the Overview tab and look for Register your cloud project section. Click the Register button.

   

   Under the See if you are eligible for non-commercial use section, Click the Get Started button.

4. Complete the eligibility form

   Google asks a few questions to confirm non-commercial use. Choose Government as the organization type, then click Next. Answer the remaining prompts as follows:

   Is your organisation considered one of the following?

   None of the above

   Government name

   Republic of the Philippines

   Will you use Earth Engine for repeat analyses over time?

   No

   Will you use Earth Engine for research?

   Yes

   Will you use Earth Engine for academic purposes?

   Yes

   What is the geographic scope of the study?

   Regional (for example, Central Luzon)

   Have you published research using Earth Engine?

   No

   Click Check Eligibility. Continue only after you see You are eligible for non-commercial use.

5. Register as a Community Member

   In Choose your plan, select Community Member, then click Next.

   On Describe your work, the options depend on your role. Choose the description that best matches what you do, then review your answers and click Register.

   When Google asks you to turn on the Earth Engine API, click Enable.

   info

   If that prompt does not appear, go to APIs & Services → Library, search for Earth Engine API, and click Enable.

2. Service account and JSON key

SINAG relies on service accounts to access the Earth Engine API. A service account is a Google account that is used to authenticate requests to the Earth Engine API. In this section, you will create a service account and a JSON key for that service account. This section requires a Google account that already has registered and Earth Engine access.

1. Open IAM & Admin → Service Accounts

   In Cloud Console, open the left sidebar by clicking the Hamburger Menu (☰) button and hover over IAM & Admin then click Service Accounts.

2. Create the service account

   Click + Create service account. In Service account name, enter a clear name (for example sarai-gee-access).

   In Service account ID, click the circular Generate icon (the circle with an arrow) so Google fills a unique ID. Then click Create and continue.

3. Grant the Owner role

   Under Grant this service account access to the project, open the Role menu. Select Currently used, then choose Owner.

   priority_high

   Assign Owner before you continue. A service account without this role cannot run AgriSense and the other Earth Engine tools in SINAG.

   Click Continue. Skip the next screen (Grant users access to this service account) and click Done.

4. Create a JSON key

   Click the new service account email → Keys tab → Add key → Create new key → JSON → Create. The browser downloads a .json file. Keep it on a private drive, not a shared folder.

1. Open the GEE service-account signup page

   Go to signup.earthengine.google.com/#!/service_accounts while signed in with a Google account that already has Earth Engine access (complete Earth Engine registration for that user first if you have never used the Code Editor).

2. Register the service-account email

   Paste the client_email from the JSON (or from the Cloud Console service-account list) and submit. Wait until the page confirms the account is registered before uploading the key to SINAG.

3. Upload the key in SINAG

When the JSON is downloaded and the service account is registered with Earth Engine, link it in your SINAG account. That walkthrough is a separate guide: Set up Google Earth Engine in SINAG.

If something fails

• Key authenticates but Earth Engine calls fail — enable the Earth Engine API on that Cloud project.
• Permission errors in analysis — keep the Owner role on the service account and finish registration on the GEE signup page.
• Quota or “not registered” errors — the Google account that registered the service account must itself be an Earth Engine user.
• Upload or locked tools in SINAG — see Set up Google Earth Engine in SINAG.
