Data discoverability
1. Project
What is your idea? What outcomes are you trying to achieve? What will the impact be on customers?
Ideas can include new data sets, functionality enhancements, customer research, business process development etc.
Improve data discoverability within LDS so that customers are more quickly and easily able to find the data they need - search results are more relevant and meaningful.
This project could include enhancements to the search algorithm itself and ranking of results, as well as to the display/ordering of search results, the ability to search by
location, and the usability/visibility of the search results sorter.

To enable a successful outcome, LINZ may also need to undertake a parallel piece of work to make changes to the terms used to tag and describe its datasets, and to
dataset lifecycle management.

Another specific problem we are interested in resolving is that related to
under
search results and the default ranking of these results by popularity. In
some cases, particularly those related to aerial imagery, customers are
seeking the latest data but are being shown the oldest. Because of this,
older imagery is continuing to be downloaded more often than new
imagery for the same area. How do we allow customers to more easily find
the latest data if this is what they desire?
