Data collected and managed by Forest Service programs is available in a map service and two downloadable file formats - in a shape file and an ESRI file geodatabase.
Metadata is available that describes the content, source, and currency of the data.
You can filter the list by the topic categories in the menu at the left to help you find information you are interested in.
You can view the feature classes in a single dataset by clicking on the name of the parent dataset at the bottom of the abstract.

Shapefiles do not exist for all National Datasets.
This format has technical limitations which make them unsuitable for multiple datasets within this clearinghouse. These constraints include file size, attribute name length, field length, number of fields, limited data types, lack of topological representations and floating-point rounding errors leading to inevitable data loss.
The EDW Team is unable to support Shapefile exports for datasets that approach those limits. Esri File Geodatabases (FGDB) will remain available. Alternative formats including GeoPackage, GeoJSON, Character Separated Values (CSV), Map Services and Geospatial Discovery Tool offerings will be used to provide open format access to these National Datasets. Once these formats are available for all National Datasets, EDW will retire the shapefile format as a supported file exchange format.
Requests for KML/KMZ output
The Enterprise Data Warehouse Team tested exporting out to KML/KMZ files as a deliverable and due to the complexity and size of the datasets this has been unsuccessful.
To obtain a KML file for any EDW dataset, go to the Geospatial Data Discovery Tool and search for the dataset. An option to download to KML is available from that website.

The EcoMap Provinces feature class contains ecological province polygons attributed with names and descriptions. The EcomapSections 2007 data set describes the ecological sections within the conterminous United States. It contains regional geographic delineations for analysis of ecological relationships across ecological

units. ECOMAP is the term used for a USDA Forest Service initiative to map ecological units and encourage their use in ecosystem-based approaches to forest land conservation and management. This is a collaborative effort with many partners. It is coordinated at the national and regional levels by USDA Forest Service staff and implemented in cooperation with State forestry agencies and others. ECOMAP mapping criteria are outlined in the National Hierarchical Framework of Ecological Units.The framework systematically divides the country into progressively smaller areas of land and water that have similar physical and biological characteristics and ecological processes.

This feature class is a polygon landslide inventory of the Tongass National Forest. The digital version of this inventory was started in the year 2000 and the once-over inventory was completed in 2017. The feature class is updated annually or as new imagery becomes available. Both field and photo interpreted landslides are

included. The inventory includes all mass wasting features--including talus slopes, snow avalanche fields, and snow avalanche chutes. Therefore, it may be necessary to exclude some mass wasting features prior to analysis depending on the intended use of the data. Each of these are coded differently in the attributes. Most of the landslide polygons were digitized on the 1998 to 2010 ortho photos in GIS, although some were digitized using imagery taken more recently. All the landslides have been age bracketed within the available photo data sets to estimate date of occurrence. Many of them were age bracketed using air photos back to the 1929 Navy Trimegon photos. All landslides have been dated before or after 1948 imagery and before or after the 1996 to 1998 imagery. There is an associated point feature class that contains the landslide initiation zone approximations. These points only exist for true landslides--debris avalanches, debris torrents, combination debris avalanches/torrents, slumps, rotational failures, and rock fall-initiated failures. The 2023 update included new slides from 2020 imagery on Chichagof Island. The 2024 update included new slides from 2023 imagery of Admiralty, Kupreanof, Mitkof, and Wrangell Islands as well as part of Kuiu Island. The 2025 update included additional slides on Mitkof, Wrangell, Etolin and Revilla Islands and adjacent mainland. The 2025 update also revised fields and some previous entries to record imagery sources and more precise dates of occurrence.
