INTRODUCTION

Unmanned Aircraft System (UAS) imagery delivered to the USGS Earth Resources Observation and Science (EROS) Center for inclusion in EarthExplorer (EE) will come from several government agencies (BLM, NOAA, Forest Service, USGS, Fish and Wildlife Service, etc.) This document defines the data delivery and ingest process, by outlining standard specifications for metadata and data formats that the USGS EROS Center will require for ingesting this data. To streamline this process, the USGS EROS Center has created a UAS Data Sharing Portal Metadata Generation Tool (), which will allow selection of values previously loaded, ensure consistency of metadata and minimize duplication.

As the UAS project data are delivered, the USGS EROS Center will be responsible for the archive of the data files and provide data distribution to the user community through the USGS tool called EarthExplorer (EE).

1.1 Purpose and Scope

The USGS EROS Center intends this specification to define the format of the UAS data delivered to the USGS EROS Center and create consistency across all government agencies providing this UAS data.

This base specification covers the directory structure and metadata requirements for UAS imagery delivered to the USGS EROS Center.

The data provider may send an e-mail to lta@ (or LTA@) requesting to allow additional UAS file extensions or data types. The request will be reviewed. If approved, the software and this document will be updated, accordingly.

Personal Identifiable Information (PII) is information that can be used on its own or with other information to identify, contact, or locate a single person, or to identify an individual in context. PII in aerial data is restricted and will not be made available to the public. Identifying PII in the data is the responsibility of the sending agency. The data received by the USGS EROS will be considered free of PII for public download. Other restrictions to the data for public availability are identified in Appendix B UAS Data Release Form.

UAS DATA MANAGEMENT FLOW

UAS activities will be project or program driven. Projects may schedule several UAS missions to capture the required data. Missions are normally over different geographic areas or over different temporal periods. Each mission may include a single or multiple UAS collects. A UAS collect is defined as the specific collect (or flight) that is flown for its data collection and is associated with a single sensor. The data acquired within a project and its missions will be transferred to the USGS EROS Center and placed in a
