About the project
NAHPU — NAtural History Project Utility — is a free, open-source digital field catalog for natural history collections, supporting major desktop and mobile operating systems.

What NAHPU catalogs
Specimen fields follow the conventions of each discipline, and a single project can hold more than one format. Three formats ship today, one is in beta, and three more are in active development.
The name NAHPU is derived from the Greater Malay Chevrotain, Tragulus napu, a small deer of the tropical forests of Southeast Asia.
Our mission
NAHPU complies with the Darwin Core standard and follows the FAIR principles and Frictionless Data. The app uses the Material Design system for a consistent interface across platforms and accommodates users visual impairments and color blindness.
NAHPU is designed with genomic studies and remote fieldwork in mind. It simplifies associating digital assets, such as photographs or audio recordings and features fields to keep track tissue quality. Built with high-performance programming languages and frameworks, NAHPU runs smoothly across a wide range of devices while minimizing battery usage.
NAHPU records detailed information about collected specimens, including their origin, collection date, site, measurements, field personnel, and collection method. Real-time statistics help you monitor collecting activities and make informed decisions to prevent over-collection and collector bias, keeping fieldwork both responsible and reproducible.
By adhering to open standards, NAHPU enables data sharing and supports automatic pipelines for transferring records from the field to museum databases, and data analytics using standard formats.
NAHPU is free and open source on all major desktop and mobile platforms, and prioritizes usability for collectors and researchers. We are actively working on internationalization, including multi-language and locale support, and welcome contributors of all backgrounds.
Looking ahead
Paleontology and marine invertebrate catalog formats are in active development, and we keep expanding the taxon lists behind every discipline, so field biologists working on other groups can use NAHPU for their own fieldwork.
Outlier detection, morphometric analysis, and deep learning image processing are in progress, with audio analytics next in line. All of it runs on the device as records are entered, so insights arrive during fieldwork.
External resources add context on the taxa you study, streamline taxon imports and validation, and support student learning. GenBank, Crossref, and the Mammal Diversity Database are among the resources we plan to integrate.
