Displaying Orthophotos

In this video I cover some of the basics of displaying panchromatic, 3-band, and 4-band orthophotos.  Although  this video makes use of Vermont data the information is relevant to anyone who uses orthophotographs.

Access orthophotos in VT using Map Services

Downloading imagery can be slow, plus it takes up a lot of disk space.  The good folks at the Vermont Center for Geographic Information (VCGI) have put together a collection of map services that allow one to stream the best available color and pancromatic orthophotos in VT into ArcGIS.  It's simple, it's easy, and it's fast.  This short video will show you how to make use of the VCGI image map services within ArcGIS 10.

AmericaView at ASPRS 2011

Rick Landenberger, AmericaView Executive Director

The ASPRS annual conference is a popular event for many of us in academic and applied remote sensing, and this year’s conference in Milwaukee was no exception. Over 1,100 attended, including a group of AmericaView PIs and their partners.

In fact, this year’s event was particularly exciting for us, as it was our first ‘Special Session’. Thanks to Tom Lillesand who raised the idea, Frank Scarpace for making it happen, and Sam Batzli for moderating, we were given 90 minutes on Wednesday morning, May 4th to showcase our projects. Special Sessions offer an opportunity and format for a series of closely related talks, and naturally we focused ours on the AmericaView mission of education, applied research, data archiving and distribution, and our most recent set of projects in Emergency Management.

After Sam introduced the speakers, I gave a five minute overview of the organization to set the context. Ramesh Sivanpillai, the WyomingView PI and current AmericaView Board chairman and resident historian followed with a talk about applied research supported by WyomingView. Ramesh’s accomplishments over the years featured examples of student-led research projects using Landsat data to assess and monitor natural resources and agricultural systems in Wyoming. Ramesh and his students have been able to support both forest and range managers as well as small farmers in Wyoming through development of new monitoring and assessment methods and via hands-on training in the use of Landsat data.

WisconsinView PI Sam Batzli, former Board member and AmericaView’s current chair of the Technology Committee, then provided examples of our data archiving and distribution efforts. Although our data mission has been somewhat de-emphasized due to the USGS’s free Landsat archives, Sam was able to show the relevance and efficacy of several of our ongoing projects, ending with a discussion of our latest multi-state project involving WMS distribution of recent NAIP imagery.

Peter Sforza, a member of VirginiaView and the current co-director for the Center for Geospatial Information Technology at Virginia Tech, followed Sam and provided examples of emergency management applications in AmericaView, including a number of efforts where moderate resolution Landsat and MODIS data have been used to map recent tornado damage, including a nice example where MODIS data was useful in mapping tornado paths. He ended with a description of MontanaView’s latest efforts in developing and maintaining a national database of volunteer remote sensing experts available to support EM efforts across the country.

I wrapped up the session with a discussion of AmericaView’s educational efforts, first providing some background on our state-level K-12, undergraduate, graduate, and professional development projects, and ending with examples of our two coordinated educational projects, SATELLITES and Earth Observation Day. I ended with a summary of the 2011 Earth Observation Day event statistics, describing how we as an organization were able to reach 2,500 K-12 students and 50 teachers this year, a new record that we hope to eclipse with next year’s event.

Thanks again to Tom Lillisand, Frank Scarpace, and Sam Batzli for the ideas and support. I anticipate that this will become a regular event in future ASPRS conferences, and hope to see you there!

NAIP Imagery for Texas

AmericaView members have been sharing information about USDA National Agriculture Imagery Program (NAIP) Imagery Viewers. This blog post shares information about such a viewer established for Texas statewide imagery.

The Texas Natural Resources Information System (TNRIS) recently launched an OGC-compliant Web Mapping Service (WMS) that features a variety of orthoimage datasets. Currently, the WMS includes the following image catalogs:

Statewide - one catalog per UTM zone per each dataset 1:

  • NAIP 2004 1 meter (1m) Color Infrared (CIR)
  • TOP 2008 & 2009 50cm Natural Color (NC) & CIR 2
  • NAIP 2010 1m NC
  • Geologic Atlas of Texas 250K

Regional

  • Texas Forest Service 2008 1m CIR - 13 East TX counties
  • HPIDS 2009 Galveston 6in NC & CIR 3
  • HPIDS 2010 Bexar, Guadalupe, and Comal Co.'s 6in NC
  • HPIDS 2010 Smith 6in & 1ft NC
  • USGS 2008 30cm Amarillo, Lubbock, & McAllen NC
  • USGS 2008 30cm Border NC
  • CAPCOG 2009 6in NC (Central Texas)

1Texas straddles three Universal Transverse Mercator (UTM) zones: z13 N, z14 N & z15 N

2 Note that for 2009, zone 14 has partial coverage and zone 13 has none.

3 High Priority Imagery and Data Sets (HPIDS), a State of Texas procurement process that uses a master contract.

Instructions for accessing the WMS in ArcGIS and ERDAS Imagine:

ArcGIS 10 instructions:

  1. In ArcMap, choose Add Data > GIS Servers > Add WMS Server
  2. Insert the URL http://raster.tnris.org/lizardtech/iserv/ows?request=GetCapabilities&service=WMS& and click OK.
  3. Either add all image catalogs at once using raster.tnris.org:80 or drill down to add individual datasets.

ERDAS Imagine 2011 instructions:

  1. Choose Open > Files of type: Web Mapping Service (*.wms) > Connect
  2. In GeoServices Explorer, choose Add Service
  3. GeoService Type: Web Mapping Server
  4. Insert the URL http://raster.tnris.org/lizardtech/iserv/ows?request=GetCapabilities&service=WMS& and click OK.
  5. Back on the main Imagine window, right-click in the Retriever space > Open GeoService
  6. Find raster.tnris.org:80 from the Select a Server dropdown menu & select OK.
  7. Expand the WMS and drag desired image catalogs onto the View.

The WMS is compatible in AutoCAD and Microstation.

Posting to the AmericaView Blog

The purpose of this post is to provide guidance on posting to this blog for AmericaView members.  Blog posts are a simply, yet effective means for getting information out in a timely manner.  It's far easier than updating a web page and because the AmericaView Blog is replicated through Planet Geospatial, it is seen by a broad audience.

Step1: Become a blog contributor
Simply get in touch with Mike Battaglia and ask him to add you as a contributor.  As the AmericaView Blog runs off of Blogger, which is owned by Google, you will need to provide Mike with your Google/Gmail account ID (e.g. landsatfan@gmail.com).  If you don't have a Google/Gmail account, signing up for one is easy.

Step 2: Create a new post

USGS EROS Image Gallery

The EROS Image of the Week Gallery assembled by USGS is a wonderful resource for educational outreach.  You can browse and download posters that demonstrate how Landsat satellite imagery is used for everything from monitoring natural disasters to detecting anthropogenic induced land cover change.  The images are very powerful and the descriptions are clear and concise.
