Looking to go beyond the basic search filters in the Living Atlas? Learn how to apply these 5 advanced searching techniques adopted from ArcGIS Online.
The Living Atlas is a one-stop shop that showcases curated environmental, infrastructure and demographic geospatial content around the world that can be viewed as an insight tool in the form of web maps or be plugged into customizable apps as a feature service. Given the plethora of information available on the Living Atlas, it can sometimes be challenging to narrow down a particular item of interest.
The Living Atlas website provides some basic ways to filter items which includes specifying sub-categories under the 7 main categories (Trending, Basemaps, Imagery, Boundaries, People, Infrastructure and Environment), filtering by the item type, last modified, region (i.e., country) and Esri-only or Authoritative-only content. Although these basic filters would suffice for a quick search, the search results can be further narrowed down by specifying certain fields and terms in the search bar.
Query your search results in the Living Atlas using fields and terms
An advanced way to search for items directly in the search bar of the Living Atlas, similar to searching for items in ArcGIS Online include querying by fields such as the title, owner, tags, item type, categories, time period and more. After specifying the field name followed by a colon, the desired term can be entered. Multiple field-term groups can be grouped by separating the components with a space, which is equivalent to the logical operator “AND” set by default. The 5 examples include:
- If the owner of the item and item type are known, they can be grouped:
- If there is potentially more than one owner, the “OR” operator can be used:
- If a term includes more than one word or for more accurate results, use quotations:
- If the title of the item is not known, search for the term in the description or tags:
- If the creation date of the item is known, query using a range of dates expressed in UNIX time. The range used in the example is from Jan 1, 2020 to Jan 1, 2021:
Alternatively, items can also be searched using a Twitter-based style using ‘@’ to indicate the owner and ‘#’ to indicate tags:
