Over the last couple of years, the NASA NSIDC DAAC has been working hard to improve the Web tool that allows you to search and sift through over 900 NSIDC data sets. We will be presenting these developments during the upcoming NASA Earthdata Webinar “Discovering and Differentiating Data with the NSIDC Search” on 16 April 2015. Please join us to learn more about the strategies that we have employed and to explore the features of the NSIDC Data Search tool.
We have recognized that it can be challenging to differentiate between data sets and determine which are most useful and relevant to your applications. In response to this, the NSIDC DAAC has been developing a data set search tool with your needs and preferences in mind. Web metrics and usability studies have been used to answer the following questions:
- How do users search for data?
- Which data attributes are of primary importance when selecting a data set?
- When similar data sets exist, how is one chosen over another?
We have found that data set differentiation is driven by both what we present and how we present it. The “what” can range from relatively straightforward information such as the measured parameter or the spatial coverage to the more complex and nuanced information such as data usage suggestions or data usage metrics. The “how” includes considerations such as making data set information scannable and comparable to tailoring relevance ranking algorithms to match user expectations.
During the webinar, not only will you get an introduction to the NSIDC Data Search tool, you will also be able to ask questions or provide feedback about the tool.
