Introduction


SDARTT is an interactive map tool used to document and track disturbance and reclamation efforts associated with surface activity requiring a BLM permit. This data is critical to the BLM’s public land use permitting process due to the number of BLM offices reporting on the 19 disturbance threats SDARTT is tracking. This data can be cross-referenced with various background layers to assist in land use and natural resource management decisions.

SDARTT can be used as a general, public, read-only application or, for approved users, can provide a variety of data uploading and editing capabilities as well.

The three primary objectives of SDARTT are:

1) to develop a dynamic surface disturbance inventory (as-built and legacy disturbance and reclamation data),

2) to use the dynamic surface disturbance inventory to aid in approving or denying new proposed disturbances near PHMAs or within specified analysis areas, and

3) to allow proponents to view, download, and analyze data as needed for reporting purposes.

Upload Tab

Use the Upload tab to access the Disturbance and Reclamation and Project/Analysis Boundaries upload tasks. These tasks are used to upload data to the SDARTT inventory.

Spatial Data Rules

Disturbance and Reclamation Upload

The Disturbance and Reclamation Upload has two distinct purposes. The first is to allow the user to upload as-built disturbance and reclamation shapefiles to the SDARTT inventory. As-built shapefiles do not need to be associated with a project or analysis boundary because they existed prior to the utilization of SDARTT.

Uploaded as-built disturbances into SDARTT are used to calculate the disturbance cap when a project or analysis boundary includes an area where as-built disturbances are located. The more as-built disturbances uploaded into the tool, the less digitizing using NAIP imagery will need to be done for accurate calculations of the disturbance cap.

The second use of Disturbance and Reclamation Upload is in conjunction with Upload Project/Analysis Boundaries. If you are uploading disturbance and/or reclamation shapefiles that have a projected (new proposed disturbance) status or shapefiles that need to be associated with a Project or an Analysis boundary you must first upload the project or analysis boundaries to the SDARTT inventory. Instructions on how to upload project/analysis boundary shapefiles can be found in the Uploading Project / Analysis Boundaries section.

To upload Disturbance and Reclamation data to the SDARTT inventory:

Note: If you link the upload to a project that has not been approved (or expired), only the "projected" locations in the upload file will be linked to the project. "As-built" locations will be uploaded, but not linked to the project. If you link the upload to an approved (or expired) project, all locations in the upload file ("as-built" or "projected") will be linked to the project.

The Upload Category type Disturbances and Reclamations window opens with a map of the disturbance/reclamation area and the associated data. Some data will be Category specific.

If errors were found in the data there will be Warning or Error text displayed in the RowStatus column.


Examples – examples of possible warning and error messages:

If no errors are found in the data you can click Save Records That Have No Errors to save your shapefile(s) to the SDARTT inventory. If you do not want to save the data to the SDARTT inventory click Cancel.

If some of the records to be uploaded have no errors and some do you can upload the files that do not have errors by clicking the Save Records that have No Errors button located at the bottom of the screen.

Note: Records with warnings will be uploaded. Changes that will be made to those records are noted in the Warning details.

Uploading Project/Analysis Boundaries

The Project/Analysis Boundaries Tool was developed to aid land managers with the approval process for proposed projects. In order to use this tool properly several steps must be taken prior to uploading any boundaries or other disturbance data.

Workflow Prior to Uploading Spatial Data

  1. After the BLM land manager receives the proper documents and proposed project shapefiles from the public land user, the land manager must create a buffer around the new disturbances. This step varies state to state and will not be addressed in the user guide.
  2. Once the project or analysis area has been created, the proposed disturbances are combined with digitized polygons using NAIP imagery for known disturbances not yet uploaded into SDARTT. To see all 19 disturbance threats tracked by SDARTT view the Data Dictionary.
  3. After these steps are completed the user should have 2 shapefiles: 1) a shapefile containing the project / analysis boundaries and 2) a shapefile containing the as-built and projected disturbances.

Note: The Project/Analysis boundaries must be uploaded prior to uploading the projected and as-built disturbances. To upload boundaries, follow the steps below. 


To upload Project/Analysis boundaries data to the SDARTT inventory:

If multiple shapefiles are contained in the zip file an interim display will appear so that the correct shapefile can be selected.

The Upload Project Boundaries window opens with a map of the Project area and the associated data.

 If some of the records to be uploaded have no errors and some do, you can upload the shapefiles that do not have errors by clicking the Save Records that have No Errors button located at the bottom of the screen.

Note: Records with Warnings will be uploaded. Changes that will be made to those records are noted in the Warning details.


Upload the associated disturbances:

The second step to upload a proposed project or analysis for disturbance calculations is to upload the associated projected disturbances as well as any existing disturbances known and not housed in SDARTT. Return to the Disturbance and Reclamation Upload section and start at step #2 to upload the associated disturbance and/or reclamation shapefiles.


Running a disturbance calculation analysis:

To run a disturbance calculation analysis use the Project Tracking Tool. Instructions for using the Project Tracking Tool are located in the Tools Tab - Project Tracking Tool section.

Back to TOC


Templates

Use this feature to download Shapefile and Geodatabase templates. There are separate templates for each of the 19 disturbance types, one for Agricultural Conversion, one for Fire, and one template that contains all disturbance types. This template is the “All Combined” template and allows the user to upload different disturbance types in one upload. There is also a project template.

The template selection window also has a notification with the date of the latest update to the templates. Make sure your templates remain current.

Clicking the question mark at the end of the notification will open a log window with the list of changes made to the templates.

All shapefiles need to be zipped (.zip) in order to upload the file(s) to SDARTT. More than one shapefile can be stored in a single zipfile.

* Note: When using Geodatabase templates you must export the Geodatabase layer to a shapefile (.shp) format.
