Dendra is a platform used to retrieve, store, manage, and curate environmental data from sensor networks.
Dendra facilitates the efficient research and monitoring of our environment through real-time sensor network management, data cleaning and exploration. We support the needs of small research groups, large state agencies, and public accessors. Whether data was logged a minute ago or decades prior, if it has a timestamp, Dendra can retrieve it and graph it.
Like a dendritic network gathering signals, Dendra enables environmental monitors to pull data from the Earth's surface to a single location — all to form a unified understanding of our rapidly changing environment through the free exchange of knowledge.
Environmental work requires access to a diverse set of dataloggers, yet many equipment providers require the use of their proprietary software, siloing users and limiting collaboration. Dendra is the way out.
We maintain retrieval software integrations with Campbell Scientific LoggerNet, LI-COR HOBOlink, The Things Network, GOES Satellite, and RanchBot, all in one place.
Sensors fail, disasters strike. Datastreams are subject to corruption and sometimes need corrections from researchers refining outliers, data managers performing QA/QC on compromised sets, or field techs recording on-site equipment incidents.
Dendra's annotation system enables users to record events and pre-define data modification rules that auto-clean and correct datasets, all while retaining original states. With flexible cleaning controls, our system enables easy, safe modification with roll-back, so groups can maintain a record of changes with maximum control.
Dendra's library of equipment and datalogger information functions as an archive of model specifications, user manuals, and photos of new and legacy technologies. Our library supplies information not only to users, but also to our data exploration system, enabling auto-configuring unit conversion, measurement calibration storage, and auto-generated datastreams.
Our data explorer supports the needs of formal research with an accessible, human-readable design. Dendra harnesses its unified data repository and rich source metadata to streamline visualization, refining and troubleshooting processes through interactive exploration tooling, data filtering, map interfacing, and simple, high-quality graphing with download. Dendra surfaces data, station metrics, and sensor information, simplifying analysis for your multi-source research efforts.
Dendra enables the management of large-scale deployment with small-scale teams through out-of-the-box tooling, open data access, and personalized support. Our staff has over 15 years of data management, equipment integration, and environmental research expertise, and we're passionate about our mission. Whether it's with legacy systems or emerging technologies, Dendra lets teams do more with less.
Researchers can use Dendra to combine datasets from hundreds of sensors or loggers from multiple vendors and organizations, as well as pull measurements of interest into presentation-quality graphs or directly into models through our API.
Technicians can manage complex deployments of heterogeneous equipment from one place, get status alerts, and use the graphing system for real-time troubleshooting. Our mobile field app will also allow incident reports to become part of the data cleaning process while in the field.
Investigators and managers who use Dendra will see a net reduction in the cost of deploying large sensor networks through the resulting increased synergy between all the components. We help your environmental work scale on a smaller budget.
The Eel River Critical Zone Observatory studies water passage through bedrock, soil, and trees within the critical zone at Angelo Reserve in Mendocino County, California. Dendra connects their 1000+ customized sensors and manages all collected data.
PREP operates several water quality sensors inhabiting brackish waters in New Hampshire. When datastreams are compromised by sensor maintenance, PREP uses Dendra's annotation system to process field notes and curate data offline.
The Nature Conservancy harnesses Dendra's integration with The Things Network to collect and deliver real-time IoT sensor data from Santa Cruz Island and the Dangermond Reserve near Santa Barbara, California.
Dendra's equation library makes calibration and calculation simpler and more efficient for hydrological data collection and monitoring.
Organizations collaborate to build a network of monitoring sites with Dendra to support California's 30 x 30 initiative.
UC Nature's Kathleen Wong explores how new tech is being used alongside Dendra to streamline processes in wildlife monitoring.
All organizations that use Dendra as a data repository own the data and have authority over its distribution.
Dendra strives to adhere to F.A.I.R. principles for data sharing. Click here to learn more.
Dendra code is open source under the 3-clause BSD License. All code can be found on our GitHub.
Dendra is intended as a service, so we internally manage the codebase instead of releasing downloadable software. Some repositories may start as private until ready for the public under proper licensing.
We would like to give thanks for the support of our funding organizations, and for the grants and contracts from our involved users.
