How to Use the Search Grid Generator

Step 1: Accessing Google Earth

To begin using the Search Grid Generator, start by visiting earth.google.com. This platform will serve as your base for identifying the area you wish to investigate.

Step 2: Selecting Your Area of Interest

Let's use an example scenario where we're trying to locate a video in the Kuala Lumpur region. Here's how to proceed:

1. Right-click on the map in the area you want to search.
2. Copy the coordinates that appear.

Step 3: Using the Search Grid Generator

With your coordinates copied, follow these steps:

1. Navigate to grid.bellingcat.com
2. Paste your copied coordinates into the search bar and press return.
3. The map will automatically center on your chosen location.

Step 4: Adjusting Your Search Area

Once you're at the correct location:

1. Use the handles on the map to adjust the area of interest.
2. Modify the size and shape until you're satisfied with the coverage.

Step 5: Selecting Grid Size

Choosing the appropriate grid size is crucial for effective searching:

1. Consider the features you're looking for when selecting your grid size.
2. For small buildings in a city, opt for a smaller grid size.
3. For larger features like settlements in expansive regions, a larger grid size may be more appropriate.

Step 6: Downloading Your Grid File

After setting up your grid:

1. Click the download button to save your grid file.
2. The file will be in KML format, compatible with Google Earth and other GIS tools.

Implementing Your Search Grid in Google Earth

Now that you have your grid file, it's time to put it to use in Google Earth Web, which offers a user-friendly interface for working with grid overlays.

Importing Your Grid

1. In Google Earth Web, look for the left-hand sidebar.
2. Click on "Projects" and then "New Project".
3. Select "Local KML file" to upload the grid file from your computer.
4. Your grid should now appear overlaid on the map.

Tracking Your Search Progress

As you conduct your search, you'll want to keep track of areas you've already examined:

1. Right-click on a grid square you've searched.
2. Select "Edit" from the context menu.
3. Modify the opacity of the fill color to mark the area as searched.
4. You can also change the color to denote different statuses based on your project needs.

Collaborating with Others

If you're working as part of a team:

1. Select "File" then "Export KML file" to save your progress.
2. Share this file with your collaborators to ensure everyone is on the same page.

Best Practices for Using the Search Grid Generator

To make the most of this powerful tool, consider the following best practices:

1. Define Clear Search Parameters

Before beginning your search:

• Clearly define what you're looking for
• Establish criteria for identifying your target
• Determine the level of detail required for your investigation

2. Choose Appropriate Grid Sizes

The effectiveness of your search depends on selecting the right grid size:

• For urban areas with dense features, use smaller grids
• For rural or less detailed areas, larger grids may suffice
• Adjust grid size based on the resolution of available satellite imagery

3. Maintain Consistent Search Patterns

To ensure thorough coverage:

• Develop a systematic approach to searching each grid square
• Move from one square to the next in a predictable pattern
• Document your search method for team consistency

4. Regular Progress Updates

Keep your investigation on track by:

• Updating grid colors or opacities as areas are searched
• Regularly exporting and sharing updated KML files with team members
• Scheduling check-ins to discuss findings and challenges

5. Cross-Reference with Other Sources

Enhance the accuracy of your investigation by:

• Comparing satellite imagery with ground-level photographs
• Incorporating local knowledge or reports
• Using multiple satellite image sources when available

6. Document Everything

Maintain the integrity of your investigation:

• Keep detailed notes on what you observe in each grid square
