CNDDB Maps & Data
Online Map and Query Applications
- CNDDB in BIOS 5 for Non-Government CNDDB Subscribers.
These robust map applications provide access to the spatial detail of both the CNDDB data and Spotted Owl Observation data in the BIOS 5 Data Viewer. Note that there are hundreds of data layers available in the BIOS 5 Data Viewer; we have just pre-loaded these data sets for your convenience.
- CNDDB subscription required. RareFind 5 is an Internet application that allows for more robust querying and reporting of the CNDDB data than the BIOS Data Viewer, but with no direct map interface. This application is a major rebuild of RareFind 4 that adds many features not found in RareFind 4, including: enhanced query functionality, better display of results, performance improvements, and better connectivity to mapping applications. Because it is an Internet application, RareFind 5 eliminates the need for users to install the RareFind 3 application on their computers and download the CNDDB data every month to update RareFind 3. Please use Firefox or Chrome for best performance.
