About Us

Tasa Graphic Arts, Inc. is dedicated to producing high quality, educational Earth science content using the latest software and digital media technologies. Our customers include middle and high school science teachers, college professors, students, and anyone interested in Earth science. Our software is designed to be used for independent study or for use by teachers in the classroom. Each program presents a comprehensive, organized, interactive study of a specific area of Earth science. These programs are intended to enhance the topics presented in Earth science texts, through videos, animations, and interactive activities. Most of our products introduce key concepts, then use proven techniques such as quizzes, essay questions, data analysis and plotting, and simulations to reinforce the information presented. Other products provide reference material including the geologic time scale, mineral databases, earthquake data, and glossaries.

Recently, Tasa Graphic Arts, Inc. has been producing interactive educational and reference mobile apps for iOS, macOS, Windows 8.1 and 10, and Android.

Tasa Graphic Arts, Inc. has been illustrating college textbooks since 1978, specializing in the area of geology and geography. In 1993 we began producing Earth science educational computer software on CD-ROM. College professors, proficient in teaching these subjects, write the text portion of the programs for college level use. Additional editing allows us to bring these subjects to the younger audience.

We welcome your ideas, thoughts, and exercises as well as feedback on our products. Please use our contact form to email us or call 1-800-293-2725. We will be happy to listen to your suggestions, provide technical support, or offer suggestions on using our apps, multi-touch books, and CD-ROMs in your classroom.
