Online Questionnaire

The questionnaire below was developed and used by the committee to gather information from key individuals and organizations involved in spatial data infrastructure development and implementation. A total of 116 respondents, 24 percent of whom were from outside the United States, submitted their answers to these questions using an online form.

Online Questionnaire: Land Change Modeling

At the request of the U.S. Geological Survey and National Aeronautics and Space Administration, the National Research Council is conducting a study to review the present status of spatially explicit land change modeling approaches and describe future data and research needs so that model outputs can better assist the science, policy, and decision-support communities. For a full statement of the committee’s task, click here.

Because the committee cannot hear from all the individuals and organizations that have valuable experience and ideas on this topic, the committee seeks your help on the following five questions.

Within the context of land modeling:

1. What data products are you using for building, validating, and running land change models?

Would you participate in a land data clearinghouse? 5. Would you participate in a community effort aimed at coordinating devel- opment and application of land change models?
