The Terradex Toolbox
Terradex’s product solutions rely on a flexible toolbox of data and services. Our data tools encompass a catalog of land activity and use data that is integrated into our technology solutions. Our services are proprietary applications built from our data collection and review processes. Terradex groups data and services into categories, and then describes the data or service, its relevance, and when applicable, the frequency of data updates. Our LandWatch, DigClean, and WhatsDown pages highlight the commonly used data sets and services applied in each stewardship solution.
Aligned with our customer-focused approach, Terradex is continuously innovating and developing new data sources and cutting-edge services to meet evolving client needs. In fact, responding to customer input is a cornerstone of our growth and how we continue to expand our catalog offerings. More details about Our Toolbox are below.
