NatureMapping Data

The NatureMapping database is the broadest and most current biodiversity database in the United States. Additionally, NatureMapping data are used to update and verify the U.S. Geological Survey's Gap Analysis Program (GAP) range distribution maps.

Data Validation Method

One of the most frequently asked questions about NatureMapping's data is "how reliable is it?" Can our customers depend on our data with confidence? Is there a confidence indicator on our output? Who validates our data and how do we weed out bias or inaccuracies?

The NatureMapping Program has demonstrated that individuals trained in the NatureMapping process are highly motivated to deliver accurate sightings.

The observational data submitted to the NatureMapping Program goes through several rigorous layers of scientific analysis:

1. All incoming data is overlaid onto federal U.S. Geological Survey Gap Analysis Program (GAP) range maps. If a data point falls within the map, it is accepted at a COARSE scale, meaning that the record is likely correct, but will be re-confirmed if a closer look (FINE scale) for that species is warranted.
2. In the case of a rare, threatened or endangered species, the data record is always subjected to a FINE scale review, and NatureMapping staff contact the individual who submitted the record.
3. If a data point falls outside of the expected range distribution map, NatureMapping staff contact the individual who submitted the record to collect additional information.
4. If a sighting is recorded in our database as "unsure of the species", it is not mapped, but held in a separate file pending verification.
5. If a sighting is recorded in our database as "sure of the species, but it shouldn't be there" it is not mapped until a local investigation is conducted.

Accuracy and Neutrality

NatureMapping has the ability to get data that would not be given to a regulatory agency because the program staff work with the community/landowners for the benefit of fish and wildlife on their respective properties. Because the NatureMapping Program is neutral, yet proactive, in preserving biodiversity within the communities, the Program has helped people overcome the fear of "What if they find something on my land?" syndrome. Instead, the NatureMapping Program provides the information necessary for landowners and regulatory agencies to work in partnership with each other. Through this collaborative effort businesses, farmers, landowners, communities, and governments all benefit as well as the species on the land.

The basic data collected and mapped by the NatureMapping Program is in the public domain and is made available to all users without charge or license. Fees are charged for detailed customized maps as requested by customers -- including municipalities, businesses, community-based organizations, private landowners, and others.

NatureTracker Technology

The basic data collection software, CyberTracker, was developed by the nonprofit CyberTracker Conservation. The CyberTracker software is a database management program that allows programmers to develop their own data collection "sequence" consisting of screens, data fields and icons.

NatureTracker is a data collection "sequence" using CyberTracker International's underlying software that works on PDA's and Pocket PC's. NatureTracker was developed by the Washington Cooperative Fish & Wildlife Research Unit at the University of Washington for NatureMapping. The license is held by the University of Washington.

The NatureMapping Program currently has NatureTracker sequences created for seven states (AR, CA, MA, NY, PA, VA and WA). The goal is to create sequences for all states.
