The Ripple Effect of an Interface Change

By Danny Dotson Source:   EPA One of the features the Interface Committee has heard that would be useful for the Geoportal to have is the ability to either search for or filter by language.  So fine, let's make that happen. But, this is going to cause work in other areas to make language searching/filtering actually work well. Why is this the case?   Metadata: Does Each Item Have a Language listed? Short answer: no. So this means for language to be a valuable search/filter option, items need to have a language included in their metadata. Many currently don't.  Most of these are very likely in English as they are geospatial data sources from various government entities in the US.  But until we make sure and the change is made, the language for these items is essentially non-existent.  So the people working with metadata would need to examine the language-less items to add the appropriate language to the item's metadata. This can be time consuming just b

Ukraine: Maps and Data

By BTAA GIN Project Team Members Feature: Ukraine Maps and Data This post lists geospatial resources related to Ukraine from many sources around the world. While the Geoportal does contain some maps of Ukraine , they are from non-Ukrainian agencies and primarily date back to WWII (or older); these maps may not provide the information our users are currently seeking. Librarians from the Big Ten Academic Alliance Geospatial Information Network (BTAA GIN) Project Team have compiled some additional, more current resources for Geoportal visitors.

Vaccine Mapper: Knowledgebase web tool to track COVID-19 vaccine developers

By Milan Budhathoki The World Health Organization declared COVID-19 a pandemic in early 2020 citing that the disease had high human-to-human transmission and it's severity to public health. As the COVID-19 outbreak began, many researchers and bio-pharma around the world were working diligently to find a vaccine that potentially cures SARS-CoV-2, the virus causing the COVID-19 global pandemic. Development of a successful vaccine would take several years and it is a tedious process that involves complex science, and thorough scrutiny by the government (i.e, authorizing body) before administering it to humans to prevent/cure disease. In-contrast to the traditional pipeline in vaccine development, COVID-19 pandemic had led to an urgency in developing vaccines at record speed. In the past, not many people were interested in the vaccine development model/science and business until COVID-19 pandemic hit hard on humanitarian and economic development.
