## NRCS Experience in Obtaining Image Data from the Commercial Satellite Imagery Library (CSIL)

- Dorsey Plunk
- National Cartography and Geospatial Center

**Notes:**
This presentation will present NCGC’s experience in obtaining satellite imagery from the Commercial Satellite Imagery Libraray

## MDOQ Coverage

**MDOQ Coverage**

**Notes:**
2006 MDOQ coverage.  Note lack of coverage in Northern Maine.  NRCS has NRI segments here.  DOQs are need to orthorectify new NRI photos.  NRCS hoped that CSIL would provide some of the needed imagery to orthorectify NRI photography.

## Slide 3

**Notes:**
Glenn Bethel has been working to get USDA access to Nextview and Clearview data.  The process wasn’t well defined.  Initially I was told to order the data from USGS’ EarthExplorer.  The above circled link takes you to a web site with instructions on how to browse and order data from the USGS Commercial Data Archive.  Although there is some overlap between the USGS Archive it is different from CSIL

## Slide 4

**Notes:**
Links to USGS search and order.  A user’s certification form must be completed prior to access.

## USGS Commercial Data Purchases Certification Form

**USGS Commercial Data Purchases Certification Form**

**Notes:**
The USGS Commercial Data Purchases Certification Form.

## EROS Data Center EarthExplorer

- Browse of USGS Commercial Data Purchases.
- USGS must change your profile to browse this data.
- Subset of CSIL.
- License uplift charges apply.

- http://edcsns17.cr.usgs.gov/EarthExplorer/

**Notes:**
EarthExplorer is a website that allows you to query and order satellite images, aerial photographs, and cartographic products through the U.S. Geological Survey.  An advantage of the EarthExplorer is that you can browse the entire Landsat archive.  The USDA Imagery Archive is only a subset full Landsat Archive.  Browsing the EarthExplorer Landsat can be especially useful if you are looking for fall/winter Landsat scene that is not in the USDA Archive.  In addition to Landsat, EarthExplorer contains AVHRR, Declassifed Satellite Imagery, EO-1 Advanced Land Imager and Hyperion, North American Landscape Characterization (NALC), SPOT (Search Only), Space Acquired Photography, Spaceborne Imaging Radar-C (SIR-C), and USGS Commercial Data Purchases – Orderable.  The USGS Commercial Data Purchases are a subset of the CSIL shapefiles.  Experience to date indicates that it is better to use the CSIL shapefiles and contact the holding agency than order commercial data from EarthExplorer.

**Notes:**
Results of a search for USGS Commercial Data Purchases in Maine.  Notice uplift charge. Also the 24 scenes are only a subset of the those in CSIL.

## Commercial Satellite Imagery Library (CSIL)

- Data with licensing that allows sharing between Federal agencies.
- Shapefiles contain metadata for holdings of IKONOS, OrbView and QuickBird.
- Shapefiles are updated on a periodic basis.
- Data requests
- Some ftp
- Remainder via request to holding agency

- CSIL US Coverage August 2006

## Ordering CSIL Data

- Robert D. Lease (NGA) 703-755-5530
- Robert.D.Lease.ctr.nga.mil
- Provide shapefile metadata for needed scenes.
- Ordered 2 scenes on Sept. 14.  Received them on Sept. 20.
- Orthorectified Ikonos on DVD in NITF.
- Geographic WGS84

**Notes:**
NRCS wanted to order two Ikonos scenes from CSIL.  Because these scenes didn’t show up as orderable from EarthExplorer, we contacted NGA directly to place an order.  Robert Lease is the NGA contact for placing CSIL orders.  The imagery was orthorectified in NITF and required some processing to convert to .img format and reproject to UTM.

## Slide 10

**Notes:**
Example of orthorectified Ikonos data over an NRI segment in Maine.  Data are from CSIL.

## Slide 11

**Notes:**
In FY2006, NRCS ordered 316 Landsat scenes from the USDA Satellite Imagery Archive.

## Slide 12

**Notes:**
69,636 NRI sites flown in 2006.  Red are 1:7,920 scale, blue are 1:12,000, and green are 1:15,840.  

## 2007 NRI Sample

**2007 NRI Sample**

**Notes:**
The 2007 NRI sample.  Hawaii will be acquired with hi-res satellite data.

## Slide 14

**Notes:**
NRCS will acquire NRI-like photography over 3,207 WRP easements in FY2007.  Scale will be 1:7,920 color with 20% forward and 20% sidelap.
