Some of the users of SDAPS. Feel free to add yourself if you are using it!
When we decided to implement scannable walk and call sheets at NationBuilder, we spent a lot of time evaluating different open source solutions. Initially what drew us to SDAPS was the implementation language, Python, which we were all familiar with, the accessibility of the codebase on Github, and the availability and helpfulness of the maintainer, Benjamin Berg, on IRC. After working with Benjamin on some changes we needed for our project, we deployed to production. For October, running up to the end of US elections in November, we were able to process over 22,000 unique contacts, resulting in saving hundreds of hours of volunteer time from inputting and verifying data manually.
Originally developed at the student body of the faculty of electrical engineering, SDAPS is used whenever there is a need to do a survey. Since its creating it has also been used by student bodies of other faculties and campus wide.
The Faculty of Science at the University of Amsterdam is (as of 2014) using it automatically correct multiple choice examinations.
Research group DE5 - CIFIDEX of the University of Vigo (Spain) uses SDAPS for investigation purposes (automatic survey processing).
GPTools uses SDAPS to help general practitioners receive patient feedback for revalidation purposes.
