Data Storage

The AIM Strategy implements standard data collection and storage so that information is readily accessed, aggregated and shared.  This is accomplished through electronic, onsite data capture and centralized data management through BLM’s national geospatial infrastructure.

Terrestrial AIM Data

Information about terrestrial ecosystems is stored in two databases at the BLM National Operations Center.  TerrADat, or the Terrestrial AIM Database, houses all BLM terrestrial monitoring data collected by states and field offices. LMF, or the Landscape Monitoring Framework database, contains the BLM terrestrial monitoring data collected for national assessments.  Terrestrial AIM datasets are available to Department of the Interior (DOI) employees via ArcGIS feature services. Instructions for the ArcGIS Online map can be found in the TerrADat Quick Start Guide. To go directly to the ArcGIS Online map, please visit blm-egis.maps.arcgis.com.

If you are a DOI employee, please consult the Accessing Terrestrial AIM Data Instructions_(V1.4) to learn how to view terrestrial monitoring information using the feature services.

The site-level summarized indicators that are available in TerrADat are also available to the public via the  BLM’s Landscape Approach Geoportal.

 

For terrestrial AIM data questions, please contact the AIM Data Manager, Sarah Burnett (sburnett@blm.gov).

Aquatic AIM Data

AquADat (Aquatic AIM Database) is the BLM database that stores Aquatic AIM indicator values for all sampled locations since 2013. AquADat allows users to access data via the BLM intranet, rather than having to request it through NAMC. Over 60 indicators are reported in AquADat resulting from field collection of the core, contingent or covariate field methods. The large number of indicators results from the fact that many indicators can be computed from one field method. For example, AquADat contains five different stream bed particle size indicators that are all derived from field pebble counts.

Indicators in AquAdat are organized from left to right in the following groups: site descriptors, biodiversity and riparian habitat quality indicators, water quality indicators, watershed function and instream habitat indicators, and lastly covariates (e.g., slope). Metadata about AquADat and a brief description of each indicator can be found here and more detailed indicator metadata, computation, and application information can be found here. All data within AquADat has gone through QC by field crews, project leads, and the NOC/NAMC, as detailed in the Aquatic Data Management Protocol. More detail about NOC/NAMC QC procedures is forthcoming.

If you are a BLM employee, follow the AquADat instructions to access Aquatic AIM indicator data. AquADat provides web-based access to all calculated Aquatic AIM indicators collected from 2013-2016. To go directly to the ArcGIS Online map, please visit blm-egis.maps.arcgis.com. If you are not a BLM employee, data requests can be made by contacting Scott Miller (swmiller@blm.gov). For aquatic AIM data questions, please contact NAMC’s aquatic analyst Jennifer Courtwright (jennifer.courtwright@usu.edu).

AquADat will be updated with Aquatic AIM data from 2017 in February of 2018. If you have immediate 2017 data needs prior to February, please contact Jennifer Courtwright (jennifer.courtwright@usu.edu). For future field seasons, we hope to have preliminary computed aquatic indicators available using an online interface immediately after data collection.
