Frequently Asked Questions: DFIRM Tools – General Questions

In what format can I submit my data?

Whenever possible, data should comply with Appendix L (April 2003 Guidelines and Specifications for Flood Hazard Mapping Partners Appendix L: Guidance for Preparing Draft Digital Data and DFIRM Databases) and should include a readme.txt file containing contact information. However, additional reference data can be included with the submission that has no Appendix L specifications (e.g. DRGs, topo data, ortho photos, other GIS data, etc.). All data that will be used for final FIRM production must be referenced in the same projection.
