Geoportal is a web portal to provide discoverability and access to geospatial data resources. This presentation will evaluate the performance of two geoportals: the Big Ten Academic Alliance (BTAA) Geoportal and Purdue University's Geodata Portal using web analytics. BTAA geoportal is a consortium effort of librarians and geospatial specialists at the 12 participating institutions who select, manage and curate the geospatial data resources. Built with Geoblacklight platform, BTAA geoportal was launched in August 2016. Purdue University's Geodata Portal is an institutional geoportal based on Open Geoportal software. Launched in December 2015, the portal includes Purdue's open access map collection, data from IndianaMap and open data from other collaborating universities in the Open Geoportal Project. To assess the portal performance and figure out what can count as "success", web analytics is collected using Google Analytics and custom scripts. Example analytics include pageview, number of downloads, usage by geographic coverage as well as user activities such as map panning and zooming. Results are visualized and analyzed with Tableau and other software. These analytic results will benefit the two portals respectively in terms of collection development, interface optimization and promotion. The performance can also be compared using these analytics to reflect on the two geoportal software and the projects' different level of collaboration.
