Spatial Data Management Group Meeting Thursday June 19, 2008/title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <h1>Spatial Data Management Group Meeting Thursday June 19th FSL 200: 10:00 am</h1> <h3>Treats: Dave</h3> <h3>Notes: Patti</h3> <h3>Facilitator: Keith</h3> <h2>Attendees:</h2>Theresa Valentine., Dave Hockman-Wert, Terralyn Vandetta., Matt Gregory, Bill D., Patti Haggerty, Keith Olson., Andrea (Library), Beth Timmons (EPA), Steven Jett (EPA), Tad Larsen (EPA). <h2>Agenda:</h2> <h3>ArcGIS Server</h3><P>Theresa is starting to develop Web-enabled applications using ArcGIS Server on a local server. She demonstrated using the ArcGIS Server Manager interface to create a service. There are several kinds of services. Publishing a map on the web is one kind of service; geoprocessing, editing geodatabases, geocoding, and ArcGlobe products are the other services which can be enabled. <br> One assembles a map layout in an ArcMap MXD file and save it using relative paths (on the MXD select File/Document Properties/Data Source Options/Store relative path names to data sources). The MXD file needs to be on the server unless you are using SDE. Note well – use a single word for the name, do not use spaces. <br> Once you have a service created, you then make a Web application to host it using the Applications tab. You can set up parameters for the task, such as edit, search, query. There is some customization for the interface that can be done but other elements, such as the ordering of the table of contents and other elements must be done using .NET programming. You can use numbers, letters and spaces in the name of the Web mapping application but no special characters. <br> KML and WMS services can also be established. It is easier to setup a simplified set of layers in ArcMap and publish that as a KML (or a KMX which is a zipped KML) than assembling the layers in Google Earth. Internet links can be enabled and used in Google Earth. Theresa mashed up the HJ Andrews in Google Earth for her demo. She is working on enabling the Google Earth controls in Google Maps. The advantage is the user does not need the GE app, just a plugin. Theresa has been stealing code as she finds it. You do need to get a Google Maps key. Terralyn says that it is not trivial to setup the ArcGIS Server. New servers will be arriving but she suggests that potential users wait until the new release of 9.3 is installed. </P> <h3>Meetings: </h3> <li>SCGIS Meeting: August 12th-15th, Monterey, California. <li> ESRI Users Conference: August 4-8 in San Diego, CA - Dave, Patti and Ray are attending. <li>NW ESRI User/Training Conference Dave, October 23-24 Sun Valley, ID: Kelly plans on attending and Theresa may also go. <li>Managing Sensor Data in Near Real Time, Environmental Information Management 2008, University of New Mexico, September 10, 2008-September 11, 2008, Theresa will attend. <li>National Hydrography Dataset (NHD) Applications Workshop: two sessions, September 16 and 17, Portland. Both sessions are currently filled but there may be some openings. This same workshop is being held in Lacey, WA on the 18th and might still have spots open. Agenda will include: <lii>How the NHD is used around the country <lii>Basic theory of the NHD <lii>Obtain, load, organize, and display data <lii>Using the NHD to make a Map <lii>Spatial and structural characteristics of the data <lii>Navigating and measuring the flow network <lii>Reach codes, Com_ID’s, levels, and the flow table <lii>Import and address point events <lii>Searching for events using addresses <lii>Searching for events spatially <lii>EventFinder – using the flow table <lii>Create linear events <lii>EventMaker <lii>Projecting the NHD <lii>Looking at other NHD data <lii>Converting legacy data <lii>NHDPlus <lii>Calculate drainage area <lii>ArcHydro <li>Lidar Lunch meetings – perhaps start again in the fall? <h3>Upcoming training:</h3> <li>ESRI 2 day Python training course taught at Lane Community College. <li>sESRI Live Video session on Mashups, Thursday, July 31, 2008, 9:00 a.m., 11:00 a.m., & 3:00 p.m. Pacific Time (US & Canada) <li>Python and geoprocessing - here is a <a href="http://www.greenteapress.com/thinkpython/" target="_blank">link</a> to a free online publication: <h3>Data Issues:</h3> <p>Terralyn suggests waiting until ArcGIS 9.3 is up before trying to work with new ArcServer.</p> <table cellspacing="0" cellpadding="8" width="95%"><tr><td> <blockquote> <a href="images/osu_dem10status.jpg" target="_blank"><img src="images/osu_dem10status.jpg" alt="map of 10 meter DEM status" height="350" width="250"></a> <p>Matt has assembled 10 m DEM’s for most of OR and much of CA. Identified by SE corner, i.e. 44123. There is a geodatabase with an index which indicates the path and name of the file. As DEM’s are acquired, the index should be updated. <br>Dave has been using the SSURGO Soil Data Viewer which lets you aggregate soils on the fly. One problem has been null values in some of the soil component fields. The Data Viewer will calculate the mean of the component even if there are null values, so the values will be erroneously low. <a href="http://soildataviewer.nrcs.usda.gov/download51.aspx" target="_blank">link</a> </p></blockquote> </td></tr></table> <h3>Software:</h3> <p>ArcGIS 9.3 expected in July – maybe John Sharrard (ESRI, Olympia) can come for the next meeting, Theresa will inquire. (He is our speaker next month)</p> <h3>Round Table:</h3> <li>Matt is working on the GNN for the NW Forest Plan comparison between two dates, they are now using over 80,000 plots in their analysis. <li>Terralyn has an older computer set up for working with LINUX <li>Dave tried using the ENVI feature extraction module to extract gravel from images. The software failed utterly because it was too good at color discrimination. The shadows and colors of the gravel did not separate well enough to be distinguished. Matt suggested using imagery software and making shadow adjustments. <li>Steven Jett says he is looking for GIS work and will volunteer as well <li>Beth Timmons, EPA, said they are developing Level IV ecoregions for New York state. The only two states other states without Level IV ecoregions are Arizona and California. <h3>Next Meetings:</h3> <h4>July 31, Richardson 313 @10:00am</h4> <p>John Sharrard from ESRI will be our featured speaker. He'll talk about what's new in ArcGIS 9.3 and perhaps what's coming beyond that. He'll be the main focus of the meeting, and hopefully will be available to go out to lunch with us afterwards to continue discussions</p> <h4>Facilitator: Terralyn</h4> <h4>Treats: Theresa</h4> <h4>Notetaker: Matt</h4> </body> </html>
