Open Data Kit is a tool set for mobile collection of data with server aggregation

Open Data Kit (ODK) is a free and open-source set of tools which help organizations author, field, and manage mobile data collection solutions. ODK provides an out-of-the-box solution for users to:

  1. Build a data collection form or survey (XLSForm is recommended for larger forms);
  2. Collect the data on a mobile device and send it to a server; and
  3. Aggregate the collected data on a server and extract it in useful formats.

In addition to socio-economic and health surveys with GPS locations and images, ODK is being used to create decision support for clinicians and for building multimedia-rich nature mapping tools. See the list available toolsfeatured deployments, and implementation companies for more examples of what the ODK community is doing.

We welcome and encourage participation from the user community. ODK is supported by a growing community of developers, implementers and users as well as various companies. Core ODK development is supported by ongoing research at the University of Washington’s Department of Computer Science & Engineering and through donations from users.

This looks intriguing. There may be some legal tech us for a tool set like this.
