MTBS has published 353 newly mapped 2019 fires for 13 western states including HI and AK. This release also includes new releases of 590 historical fires for 2000 – 2017. With this release, the published MTBS data record now spans 1984 through 2019 and includes 26,557 records.
MTBS has released the remaining 716 fire mappings for 2018, bringing the total release for 2018 fires to 1,129. This release also includes a comprehensive reprocessing of the entire MTBS archive (1984 through 2018) to introduce consistent vector attribution and metadata updates, plus an additional 1540 new fire mappings and dozens of revisions to previously mapped fires spanning the archive. With this data release to MTBS.gov, the total number of fires mapped by the project increases to 25,614.
MTBS has published 413 new fires to MTBS.gov. This data release contains 2018 fires from 15 western states including AK. The full release of the 2018 data is anticipated to occur by the end of fall 2020. With this release the MTBS data record now spans 1984 through 2018. This data release also contains revisions of previously release mappings from previous fire years, bringing the total number of fires mapped by the project to 23,372.
On June 25, 2020, the "Changes to the Monitoring Trends in Burn Severity program mapping production procedures and data products" paper was released in the journal Fire Ecology (https://doi.org/10.1186/s42408-020-00076-y). This paper describes how the MTBS program's burned area and burn severity mapping methods have changed through time, and how these changes subsequently affect the burned area and burn severity products. Overall, we found that remapped MTBS products can be significantly different from
The complete dataset for the nationwide 2018 fires is anticipated to be released by the end of August 2020. MTBS is currently developing and will publish a tentative schedule for future data releases. Please check back here for additional updates.
MTBS released 1,296 new fires to MTBS.gov bringing the total number of fires mapped by the project to 22,969. This data release contains all 2017 fires. With this release the MTBS data record now spans the years 1984 through 2017.
Prior to the MTBS.gov website update in Summer 2017, this dataset had multipart features displaying a separate record for each polygon (i.e., multipart features exploded). In the current version of the website, multipart features in the attribute table have been modified to reflect a one-to-one relationship to the number of published fires (i.e., multipart features unexploded). Therefore, the number of records in the attribute table is reduced and accounts for the discrepancy in the number of records between the two versions.
The MTBS project has released a new version of the QGIS Fire Mapping Tool (FMT). The FMT is now compatible with QGIS 2.x and 3.x with this release.
