Acknowledging OpenTopography and Hosted Data

OpenTopography hosts datasets collected by many research, governmental, and non-profit organizations funded by a variety of sources. The data user bears sole responsibility for recognizing the role of the data provider through co-authorship, citation, sponsor acknowledgment, and/or attribution, as appropriate and consistent with professional standards and sponsor requirements. To facilitate this responsibility of the user, OpenTopography provides citation and acknowledgment language and examples specific to each hosted dataset as well as the global datasets it provides. This language may be found on a dataset's access page and through a dataset's metadata. OpenTopography continues its practice of providing a Digital Object Identifier (DOI) for each hosted dataset as a means to facilitate data citation.
 
NSF policy stipulates grantee responsibility for assuring acknowledgment of material based on or developed with NSF support in any publication, including web pages. In addition, NSF requires oral acknowledgment during all news media interviews. In some cases, the grants or funding sources of OpenTopography community members or other data providers must also be cited or the disclaimer is also required. Users' acknowledgments of OpenTopography support also provides a measure of OpenTopography's success and will help to ensure continued funding.

Citing and Acknowledging OpenTopography and Hosted Data

We aim to provide clear guidance to users on proper scientific citation and acknowledgment of OpenTopography-hosted data.
 
We generally follow the citation schema standard set by DataCite which defines a citation approach around Digital Object Identifiers (DOIs). OT provides a DOI for each hosted dataset as a means to facilitate data citation. Inclusion of the dataset’s DOI in users’ data citation ensures that the dataset can be accessed and reused, data impact can be tracked and that data producers and collectors are recognized. Data sources should be cited in the References section of users’ publications.

High-Resolution Lidar

Most of OpenTopography’s high-resolution airborne lidar data (point cloud or raster) was funded, collected and processed by an organization on behalf of a PI. For such datasets hosted by OT, our recommended format includes the following seven properties of the schema:
Author (PublicationYear): Title, Version. Collector, Distributor. Identifier
 
in which
Author is the PI whose intellectual work led to the creation of the dataset, identified in the Collection Overview in the metadata.
PublicationYear is the year the present version of the dataset was first released, identified in the OT Collection Name in the metadata.
Title is a combination of [OT Collection Name] and [Collection Platform], found in the metadata. Some customization may occur, depending on the OT Collection Name.
Version is the version of the dataset and only applies to versions greater than 1 (usually applies to raster products, see below) and may be found in the metadata.
Collector is the organization which funded, acquired and processed the raw lidar data led by the PI, found in the Dataset Acknowledgment of the metadata.
Distributor is OpenTopography.
Identifier is the DOI, found in the metadata.

For airborne lidar datasets collected by an organization without an identified PI, our recommended format includes the following seven properties:
OrganizationShortName (PublicationYear): Title, Version. Collector, Distributor. Identifier
 
in which
OrganizationShortName is the abbreviated name of the institution which provided the intellectual lead and funding for the creation of the dataset, identified in the Collection Overview in the metadata.
PublicationYear is the year the present version of the dataset was first released, identified in the OT Collection Name in the metadata.
Title is a combination of [OT Collection Name] and [Collection Platform], found in the metadata. Some customization may occur, depending on the OT Collection Name.
Version is the version of the dataset and only applies to versions greater than 1 (usually applies to raster products, see below) and may be found in the metadata.
Collector is the organization which funded, acquired and processed the raw lidar data led by the PI, found in the Dataset Acknowledgment of the metadata.
Distributor is OpenTopography.
Identifier is the DOI, found in the metadata.
