GIS - What's New12/01/2010
NRCS-MI GIS Announcements
Field Office Server UpgradesITS is in the process of upgrading storage space on field office servers. These upgrades should allow complete installation of remaining 2009 and 2010 NAIP imagery, as well as the 35mm slide imagery specific to each office.
USDA-MI Section MapsThe USDA-MI Section Maps have been updated to include the 2010 NAIP aerial photography.
Users are reminded not to mass-download these maps due to network performance issues. Viewing the maps online and/or saving individual maps (when necessary) is totally acceptable, but NRCS-MI staff who wish to keep a local copy of an entire county should contact Brent Stinson, NRCS State GIS Specialist.
Client Geodata PrivacyThe confidentiality provisions in Section 1619 of the 2008 Farm Bill forbid NRCS from publishing or distributing any client-specific geospatial information without the client's written consent.
Examples of unacceptable geospatial data disclosure include, but are not limited to: - Distributing any representation of a client's tract, field, or conservation practice information - Public display of digitized field boundaries when the physical location is stated or can be determined - Publishing land unit information, including tract numbers and acreage - etc.
GIS Skill Builder Updates
In order to comply with the above-mentioned information disclosure policies of the 2008 Farm Bill, NRCS-MI GIS publications will no longer contain real-life scenarios. All existing NRCS-MI Skill Builders have been modified to exclude any references which could be interpreted as being in violation of NRCS geospatial data disclosure policies.
Users are asked to destroy all NRCS-MI Skill Builders which were printed and/or downloaded prior to 2/1/09.
Geodata Updates
2010 NAIPThe National Aerial Photography Program (NAIP) imagery for 2010 has been delivered to the State Office. The imagery will be deployed to USDA Service Centers in the following months, as ITS completes the field office server upgrades. CGI Framework v10aThe State of Michigan Center for Geographic Information (CGI) Framework version 10a data update has been deployed to all field office servers. This data includes transportation, hydrography, government units, cadastral data, etc. NRCS Hydrologic UnitsThe NRCS hydrologic unit datasets have been updated on all servers. The update includes all "wbd" watershed data layers, not the legacy "huc" shapefiles. Due to a change in data structure, the 12 digit county watershed layers, ("wbdhu12_a_mi[FIPS].shp"), are no longer clipped to the county boundary, but include the 12 digit watersheds within each 8 digit watershed which covers any portion of the county. 35mm Slide ScanningWe have completed over 70 counties to date, with additional counties underway. This imagery consists of all of the available FSA 35mm compliance slides for each county, often dating back to the late 1970's. These slides are critical to the NRCS wetland determination process and are being digitally captured to prevent further deterioration Those interested in acquiring scanned 35mm slide data should contact Brent Stinson, NRCS State GIS Specialist.
