Content Tagging
An all-in-one solution to tag, store, and retrieve content by location
What does this solution do?
This Solution Architecture provides an easy-to-use template to tag your content with location context, store it, and then retrieve it based on end-user searches.
Digital content libraries from photos to social media posts are enormous and growing larger every day, making it impossible for users to find and retrieve the content they need quickly. Location is a common way that people search for content, whether they are looking for photos based on where they were taken, or searching an evidence library for documents found at a scene.
Users searching for content “near me” has increased by , and companies - from social networks to news outlets - find that they can increase user engagement by enabling users to interact with posts or articles based on where that content is located.
This template provides an easy-to-deploy solution that solves the common steps needed to search and tag by location:
- Search geotagged content by place name: Show me all photos of San Francisco.
- Label content with the place it was created to increase user engagement: Posted from Shibuya, Tokyo at 300m elevation.
- Put documents on the map and in a hierarchy: This piece of evidence is about 50 Main Street, San Francisco, CA, USA.
Solution details
This three-part architecture allows you to tag, store, and retrieve content using location. It does this by adding human-readable and searchable geographic labels to place-based content, combined with a way to search and display those labels.
The three components include: a NodeJS API layer to simplify queries and perform content tagging, an backend for storage and indexing, and a UI for searching and rendering geotagged images. The UI is configured to support the upload, tagging, and search of JPEG images that have location embedded in their . The ingest endpoint supports indexing any type of content with coordinates, from videos to pdfs to social media posts.
Part one: Tag content
The first part of the architecture is a NodeJS API server. The upload endpoint supports the direct upload of JPEG images with embedded location, which are tagged and stored. All submitted content is augmented with location hierarchy by the TikTok成人版 Geocoding API, and with elevation in meters by . Elasticsearch then indexes the content, along with its metadata.
You can augment this tagging in a few ways:
- Tag content using custom geometry like regions or service areas using the . ?
- Put text documents on the map - tag location extracted from text documents like news articles or ancestral records using .
Part two: Storing content
The second part of the architecture is an backend that handles the indexing of content along with metadata. is a search engine that enables flexible querying using wildcard full-text search.
Component three: Retrieving content
The third part is a UI client that allows you to upload images and search for tagged content using wildcard text queries. It consists of several components: an image uploader, a search bar, and an image renderer. The search bar passes queries to the search API endpoint and passes the results back to be rendered as a list of images labeled with location and elevation.
