MODIS 250-meter Imagery
June 29, 2004
“When all our resources are either grounded or used up, MODIS is there providing us data several times a day, statewide.”
--Corey Doolin, Zone Coordinator Upper Yukon Zone BLM
“MODIS was great in detecting fires in remote locations. Almost this entire summer we were out of resources used for detection flights, MODIS filled the gap for us.”
--Corey Doolin, Zone Coordinator Upper Yukon Zone BLM

NOAA/NESDIS-FCDAS, USGS- EROS, & UAF-GINA Partnership • Goal: delivery in less than 24-hours • FCDAS receives data • GINA transports data • EROS processes and archives • GINA provides to users
Landsat 5: 2004 vs. 2005 Alaska acquisitions
2004-7 Landsat 5 Legacy ! 25 scenes in 2004 into National Archive ! 3777 scenes in 2005 into National Archive ! 5241 scenes in 2006 into National Archive ! 1633 scenes in 2007 into National Archive
– Landsat is the workhorse of land remote sensing – No SLC gaps – Twice the coverage (L5 + L7)
! New inroads into Alaska Fire Service – Sheenjek Fire successful emergency response – Awareness among Fire Management Officers – Post Season perimeter mapping
Alaska Statewide Digital Mapping Initiative
www.alaskamapped.org
• Underway July 1, 2006 (State FY07) • Partnership among:
– Dept of Military and Veterans Affairs – Dept of Natural Resources – University of Alaska – MOU endorsed by Governor Murkowski; renewal
endorsed by Governor Palin
• Intended initially to capture $25M of NASA funds through a State in-kind $8M
• To date – State: $2M (SFY07) + $2M (SFY08) + $2M (SFY09) = $6M total State + $14M Federal Authorization in State Budget

1955 – 1979 – 2002
The Problems with Current Maps
• Imagery out of date – Alaska last photographed in entirety in 1978-1986
• Film imagery (some has been scanned)
– About 30% of the state has high-resolution imagery less than 5 years old
• Digital Elevation Models (DEM) – Coarse: 30 - 60 post meter spacing – Inaccurate: created by digitizing USGS
topographic maps made in the 1950’s using poorly controlled air photography
Alaska High-Altitude Photography Program
Alaska was photographed from high-altitude U-2 and ER-2 aircraft between 1978 and 1986 under a multi-agency, State and Federal partnership led by the USGS.
Color swaths indicate the number of times the area was imaged by SRTM

SDMI Program Deliverables
• Statewide Orthoimage – Multi-Scale
• Better Coordination across the spectrum: Government and Private
SDMI repository and browse interface: browse.alaskamapped.org
18 scenes for this view area
zoomed in: 11 scenes for this view area
2003 scene is shown in “best data layer”. Scenes from 1978, 1980, and 1952 are also available for download.
• What makes it the “Best Data Layer”? – Spatial resolution – Vintage – Spectral
• How do I get the layers I can’t see? – Download button
• How do I view the layers I can’t see in the browse interface? – SwathViewer: sv.gina.alaska.edu
• How do I follow Scott’s excellent example and contribute data to the public archive? – Contact GINA
SwathViewer: sv.gina.alaska.edu
• What is an OGC Web Mapping Service?
– Open standards service that dynamically produces a spatially referenced image for use in mapping applications

• Best Data Layer – Scales automatically
– Three scales: low (>250-m), mid (>15-m), & high (25-m to sub-1-m)
• Extras – DRGs: scanned USGS topo maps
– NOAA Charts
– Landsat Panchromatic
– Enhanced Blue Marble for Alaska region

The bdl_low_res layer contains the Blue Marble Next Generation July dataset (http://www.nasa.gov/vision/earth/features/blue_…). It is intended to be viewed at scales greater than 250m per pixel
The bdl_mid_res layer contains a Landsat mosaic generated by the USGS from data acquired from 1988 to 1992 and a simulated true colour Landsat mosaic provide by Earthstar Geographics LLC. It is intended to be viewed at scales greater than 15m per pixel. Imagery copyright Earthstar Geographics (http://www.terracolor.net).
The bdl_high_res layer contains data from a variety of sources and is intended to be viewed at scales from 25m per pixel to 1m per pixel. Images courtesy of Digital Globe, USDA-NRCS, USDA-FS, USGS, BLM, NPS, FAA, Alaska DNR, DMVA, DCED, DOT&PF
Landsat Pan This layer group provides a single banded dataset derived from Landsat 7’s pan-chromatic band. It was generated from the Landsat 7 datasets provided by OnEarth. It is broken up into two layers to increase the rendering speed.
DRG This group provides four layers, “drg_24k”, “drg_25k”, “drg_63k”, “drg_250k”, which contain the USGS topographic maps for the scales 1:24,000, 1:25,000, 1:63,360, and 1:250,000 respectively. For more information please see the USGS’s topographic maps website.
Shaded Relief NED This group has one layer which provides a shaped relief dataset derived from the National Elevation Dataset (NED) *
Blue Marble This layer provides an Alaska centric version of NASA’s original Blue Marble dataset. It has been “brightened” up and only covers Alaska and the surrounding area.
NOAA Charts The Charts service is meant to provide a unified view of the RNC data, without the collar information. The service is designed to only display charts that are meaningful at the requested scale.
