Fusion Tables automatically indexes your data, allowing for fast querying and filtering. This means you can quickly find specific information within your data.

Data validation is also a key feature, enabling you to restrict the types of data that can be entered into a column. For example, you can specify that a column should only contain dates or numbers.

Data Search, Publication, and Reuse

Fusion Tables allowed users to reuse publicly published data sets or data sets shared with them by creating visualizations and filtered views in new tabs.

These views wouldn't affect the original file for the owner or others, but would appear whenever the user who created them opened the file.

The new views were indicated with a dotted line outline, making it easy to distinguish them from the original data.

Users could not edit the read-only data set, but they could still create new views and visualizations without affecting the original data.

Uploading data to Google Fusion Tables is a straightforward process. You can log in to Google Docs, create a new Table, and upload your file from there.

Excel and CSV files are the most commonly used formats for uploading data to Fusion Tables. You can also upload KML files to bring in spatial information like locations or polygon definitions.

Only numeric fields can be used to categorize data, so it's a good idea to create these fields before uploading your data.

Here are the steps to upload data to Fusion Tables:

  1. Click Choose File.
  2. Browse to find the file you want to upload.
  3. Click Next >>.
  4. Click Next >> again.
  5. Update the Table name, add attribution data, and/or change the description.
  6. Click Finish.

Merge Tables

Merging tables is a powerful tool in data management. It allows you to combine data from multiple sources into a single, cohesive dataset.

To merge tables, you need to select the tables you want to merge. In the example, the Population table is merged with a table containing zip code boundaries. This is done by selecting Merge in the Population table.

The table containing zip code boundaries has two columns of interest: "name" and "geometry". The "name" column contains the zip code, while the "geometry" column contains KML for the corresponding boundary.

You can use these boundaries to represent the locations on a map, otherwise they will only be points. To merge the tables, you need to select the columns you want to merge on. In this case, the zip code columns in both tables need to be matched.

The matching process works by looking for exact string matches in the selected columns and then linking matching rows together. This is done by selecting the radio button next to "Zip" in the left column and the radio button next to "name" in the right column.

Once you have selected the columns to merge on, you need to enter a table name for your merged table. A suggested name is "Bay Area Population merged with KML".

Here's a step-by-step guide to merging tables:

  1. Make sure you have the Population table open in your browser.
  2. In the Population table, select Merge.
  3. Paste the following URL in the Text box under Merge with: https://www.google.com/fusiontables/DataSource?docid=10Py_fhQGH_uPJt9BFHKMWv3Qdg6kbh6dQ_ncAA
  4. Click the Get button.
  5. Select the columns you want to merge on.
  6. Enter a table name for your merged table.
  7. Click Merge tables.
  8. Select Visualize > Map.

After merging the tables, you can visualize the data on a map. You may initially see "data loading" messages, but wait a minute and zoom in or refresh to see the correct images.

Reviews are essential for evaluating the effectiveness of data management tools. Google Fusion Tables is one such tool that has been reviewed by the Digital Humanities Blog at the University of Alabama.

Google Fusion Tables is a powerful tool for managing and visualizing data.

Data Editing and Visualization

Fusion Tables automatically detects various data types during import and generates a few appropriate visualizations, including row views, card views, and map visualizations.

These visualizations can include standard strings, numbers, images, and KML, making it easy to get a quick overview of your data.

The map visualization feature is particularly useful, especially when working with location data, and can be automatically created for tables with multiple types of location data.

Fusion Tables also integrates seamlessly with Google Maps, allowing you to visualize your data on a map and even style it with different colors and visual presentations.

Editing

Editing is a crucial step in data management, and it's great to know that some tools make it easy.

You can add rows to a table, which is a fundamental aspect of data editing. The UI supports this feature, making it accessible to users of all levels.

Editing data is also possible programmatically through the Fusion Tables API, giving developers more control over the editing process.

Data Visualizations

Fusion Tables automatically detected various data types in the data and generated a few appropriate visualizations during import.

The visualizations included a row view and a card view for all tables, and a map visualization was automatically created for those with many types of location data.

Data types supported within the table view included standard strings, numbers, images, and KML.

Fusion Tables also supported KML point, line, and polygon objects as a native datatype in the tables, visualized on top of Google Maps' basemap.

The integration of Fusion Tables with Google Maps through the FusionTablesLayer allowed for fast, server-side rendering of large and complex user data onto the Google Maps base map.

This made it possible to show thousands of user data points on a map, rather than the previous limit of around 200.

Filtering is a crucial step in data editing and visualization. Simple filtering tools can automatically summarize values in data columns.

These summaries help you quickly understand the data and make informed decisions. By doing so, you can focus on the most important information.

With checkboxes, you can easily filter the visualized data to show only the relevant information. This saves time and reduces clutter.

Maps

Maps are a great way to visualize data, and Google Fusion Tables makes it easy to create interactive maps with just a few clicks.

Fusion Tables can automatically detect location data, including latitude/longitude information, KML place descriptions, and some types of placenames and addresses.

To geocode addresses, select "Map" under the "Visualize" tab, and the program will automatically begin geocoding based on the left-most field containing spatial information.

Geocoding addresses can be tricky, but it's easier if you separate items with spaces only, no commas, like "134 Chapel Drive Durham NC 27708".

  4. Copy the HTML and JavaScript code from the Publish dialog box.
  5. Paste the code into a new file in your Github Pages repository.
  6. Commit the file and visit the page at http://USERNAME.github.io/FILENAME.

Deprecation and Legacy

Google Fusion Tables had a significant impact on the way people worked with data, but its time was limited. It was announced that Fusion Tables would be retired on 3 December 2019.

Google provided an open-source archive tool to help users export their existing Fusion Tables maps to an open-sourced visualizer. This was a welcome move, but it was still a blow to the many users who had grown attached to the service.

History and Impact

Fusion Tables was inspired by the challenges of managing scientific data collections in multi-organization collaborations.

The website launched as part of Google Labs in June 2009, announced by Alon Halevy and Rebecca Shapley.

A scientific paper in 2010 further described the service, providing more insight into its functionality and capabilities.

Deprecation

Deprecation can be a tough pill to swallow, especially for users who have grown attached to a particular tool or service. Google's decision to retire Fusion Tables in December 2018 was a prime example of this.

Fusion Tables was retired on 3 December 2019. An open-source archive tool was created to help users export their existing maps to an open-sourced visualizer. This was a kind gesture from Google, but it didn't change the fact that the service was no longer available.

The deprecation of Fusion Tables was met with disappointment from its loyal user base.
