After receiving the parcel ID file, it is very important to view it correctly and use it properly in the field. Two main tools are available for this work: Google Earth and Google Maps / Google My Maps. Each has its own advantages, so using them together according to need works best.

This guide explains how to open the file, understand the area, and get accurate directions to the required house while working in the field.

1. Opening the File in Google Earth

First, open the parcel ID file in Google Earth. The file is usually in KMZ or KML format (or inside a ZIP).

1. Download the file to your mobile or computer.
2. If it is a ZIP, extract it first.
3. Open the Google Earth app or desktop version.
4. Open/import the file.

Once the file opens, houses and their parcel IDs become clearly visible on the map. This makes it much easier to understand the complete layout of the area, the location of houses, and the distances between them.

In Google Earth you can zoom in and out to review the entire area. This helps you estimate before going to the field which house is where and which parcel ID belongs to which house.

2. Importing the File into Google My Maps

If you want to use the parcel IDs more effectively on a map, import the file into Google My Maps:

1. Open Google My Maps (mymaps.google.com or via mobile).
2. Create a new map.
3. Click the Import option.
4. Select your parcel ID file (KML/KMZ).
5. After the file opens, all parcel IDs and their locations will appear on the map.

You can now search for any required parcel ID and see its exact location. Later you can open that location in Google Maps to get directions to the house in the field.

3. Advantage of Google Maps (Field Navigation)

Google Maps is more useful for field work because it shows your current location in real time. It also provides complete directions to the target house.

If you know the location of a house with a certain parcel ID but are not there yet, Google Maps can give you the accurate route from your current position to that house.

In areas with weak internet you can also download the map in advance for offline use. This makes field work more convenient.

4. Best Workflow (Recommended Order)

To make parcel ID work more effective, follow this sequence:

• Step 1: Open the file in Google Earth so you clearly understand the area and house locations. Zoom and build a mental picture of the whole area.
• Step 2: Import the same file into Google My Maps so all parcel IDs are clearly visible and searchable on the map.
• Step 3: Open the location of the required parcel ID in Google Maps, get directions, and go to the field.
• Step 4: Once in front of the house, verify the parcel ID and enter it in the CHI app (never assign while sitting at home).

In this way the parcel ID file is no longer limited to just viewing — it becomes a practical tool for finding the correct house and reaching it in the field.

5. Important Precautions

• Google Earth satellite imagery can sometimes be outdated — always verify yourself in the field.
• Never assign the same parcel ID to two separate registrations (duplicate problem).
• Keep a written record of used parcel IDs in a register.
• Change the color of used pins in Google Earth so they are not reused by mistake.
• In low-internet areas, pre-load the map and file beforehand.

Final Words

Google Earth helps you understand the area and house locations, while Google Maps provides the route and navigation. Using both in the correct order makes parcel ID work more accurate, faster, and easier.

Correct file + Google Earth (understanding) + Google Maps (navigation) + verification in front of the house = better and more accurate data.
