Combining Data with the Placekey QGIS Plugin: Unlocking a Powerful SEO-Optimized Solution

Introduction:

Introducing Placekey, a free address and point-of-interest (POI) matching tool now integrated with QGIS via the Placekey Connector Plugin! Joining data from different sources can be a common problem, but Placekey solves it by normalizing, validating, and geocoding addresses and POIs to generate a unique Placekey for each place in your dataset. Traditional approaches like joining by attribute or spatial join can have downsides and create uncertainty. Placekey offers a standardized way to identify physical places and provides a common identifier across organizations. It’s free to use and comes with an open specification. The Placekey Connector Plugin makes it easy to join disparate datasets using Placekey, and it also offers a lookup dockwidget for querying placekeys directly on the map. With the plugin, you can send the desired fields as payload to the bulk API endpoint and get the resulting Placekeys. You can then store and use the data for future joins. Placekey is currently fully supported in the US, and it has unique advantages compared to other closed systems like what3words and Google Place ID. To use the plugin, simply get an API key at placekey.io and save it to your QGIS installation. You can also explore other integrations of Placekey with R, Python, Snowflake, Google Spreadsheet, and more. The magic of Placekey lies in its simplicity and effectiveness. With just a few lines of code, you can use the Placekey API to get a placekey for any POI based on its placename and location information. Give it a try with the provided sample dataset and experience the power of Placekey. Download the sample dataset and the prototype script to get started.

Introducing Placekey: A Game-Changing Tool for Address and POI Matching

Joining data from different sources can be a challenging task. Whether you’re working with state and local government open data, business reviews, real estate data, or environmental information, you may encounter difficulties in matching and integrating datasets.

Traditionally, there are two common approaches to joining datasets: joining by attribute and spatial join. However, both methods have their downsides. Joining by attribute may result in mismatched data due to spelling errors or the absence of a common identifier. On the other hand, spatial join can be complicated when assets are closer to each other than expected, leading to misleading joins or a many-to-one relationship.

To address these challenges, a free tool called Placekey has been developed. Placekey aims to create a standard for identifying physical places by generating a unique identifier, or Placekey, for each place in a dataset. This tool normalizes, validates, and geocodes addresses and POIs behind the scenes, ensuring accurate matching and integration of data.

The main advantages of Placekey include:

1. Common identifier across organizations: Placekey provides a universal identifier that can be used across different organizations, making data integration seamless.

2. Free to use, free to store: Placekey is an open tool that is available for anyone to use and store their data without any cost.

3. Open specification: Unlike closed systems such as what3words and Google Place ID, Placekey offers an open specification, allowing for transparent and customizable usage.

Although Placekey is currently fully supported only in the US, it offers unique advantages compared to other tools like Plus Codes. Placekey not only indicates spatial information but also includes the “WHAT” part, which contains encodings of the address and the POI.

To make the use of Placekey even more convenient, a QGIS Python Plugin called Placekey Connector has been developed. This plugin facilitates the joining of disparate datasets by sending desired fields as payload to the API endpoint. It also includes a lookup dockwidget, allowing users to query single Placekeys directly on the map.

Using the Placekey Connector plugin is simple:
1. Obtain an API key from placekey.io and save it to your QGIS installation.
2. Select the desired features and fields to be joined.
3. Choose whether to copy the original feature and add the Placekey or return only the feature ID and the resulting Placekey.
4. Enjoy your data with added placekeys!

For those interested in using Placekey in other “clients,” there are integrations available for R, Python, Snowflake, Google Spreadsheet, and more.

If you’re still skeptical about the magic of Placekey, let’s dive into a minimal example using raw Python. By providing a placename and location information, you can easily obtain a Placekey for a specific POI.

To demonstrate this, a sample dataset is provided along with a Python script. The script utilizes the placekey.io API to generate placekeys for each entry in the dataset. The results are displayed in a matter of seconds, showcasing the power and simplicity of Placekey.

If you’re eager to explore this game-changing tool, give the Placekey Connector plugin a try and see how it revolutionizes the way you match and integrate datasets. Download the plugin and start unlocking the true potential of your data with Placekey.
