  1. GIS Virtual Water Cooler August 22 - 23, 2011 Presenters: Theresa Valentine and Adam Skibbe* * With a little help from our friends

  2. Overview • Let’s talk about GIS • Seriously, let’s converse… ask questions • GIS Tools – what’s popular • Desktop • Raster • Online mapping • Open Source Alternatives • Emerging Trends • GIS at LTER Sites • Geospatial Analysis Committee • GIS Working Group • Main initiatives – LTERMapS, GeoNIS • Next steps for GIS WG

  3. GIS Tools • Data management of geospatial data is inclusive of both GIS and remote sensing products though specific disciplines are different in scope, focus, and standards. • Desktop GIS • Vector and raster (image) datasets • More robust: advanced cartography, analysis, geostatistics, etc. • ESRI – ArcGIS 10.0 sp2 • Integration with relational databases (Oracle/SQL Server) • Remote Sensing • Focus on raster (image) analysis and classification (See GAP, NDVI, Etc.) • LiDAR emerging technology • ERDAS, ENVI, IDRISI, GRASS software products

  4. On-line Tools • Online mapping providers • Google Maps, Earth • Bing! • Yahoo • Mapquest • Customized applications • ArcGIS Server 10 • ArcGIS Online • API’s • Data services • WMS,WFS,WCS,etc • USGS, USDA, ESRI, Etc.

  5. Open Source Tools • Open Source GIS • Nearly all of the most popular/trusted projects are sponsored by the Open Source Geospatial Foundation (http://www.osgeo.org) • Nearly all OSGeo products can interact with ESRI data formats and services • Desktop • Quantum GIS, gvSIG, GRASS GIS, uDIG, … • Server • MapServer, GeoServer, MapGuide, OpenLayers … • Database • PostGIS for PostgreSQL is the favorite, and standards-based, while MySQL Spatial is immature and not standards-based • Libraries • GDAL, OGR, FDO, GEOS, …

  6. Emerging Trends • ISO standard metadata (instead of FGDC) • Cloud computing • Web service based • Merging data/applications from a variety of sources • Collaboration sites (social networks): people with common interests • Citizen scientists • Expectations for “google like” applications • Mobile device applications • Moving from coverages/shapefiles to geodatabase (SDE and file, Oracle, SQL). • Movement from ESRI GRID to geodatabase raster and to image servers. • Embedding applications in web pages (GIS API’s, adding functionality)

  7. GIS at LTER Sites • All sites using GIS except for CCE, PAL, and SBC (as of 2010 survey), although these sites use other spatial data application. • 17 sites using GIS server technology. (web mapping) • Search of data at LNO: only 23 data sets (sites working on getting data into EML) • Search of bibliography at LNO: • Your search on GIS resulted in 103 references. • Examples from 3 sites and LTERMapS:

  8. GIS @ Konza • Nippert, J.B., T.W. Ocheltree, A.M.Skibbe, L.C. Kangas, J.M. Ham, K.B. Shonkwiler Arnold, and N.A. Brunsell (In Press). Linking plant growth responses across topographic gradients in tallgrass prairie. Oecologia.  • Craine, J.M., J.B. Nippert, E.G. Towne, S. Tucker, S.W. Kembel, A. Skibbe, and K.K. McLauchlan. 2011. Functional consequences of climate-change induced plant species loss in a tallgrass prairie. Oecologia 165: 1109-1117. • Impacts of spatially heterogeneous nitrogen to grazer distribution and activity: Effects on ecosystem function in tallgrass prairie -PIs: A. Joern, J.M. Briggs, D. Goodin, E.G. Towne and A.M. Skibbe

  9. GIS @ Baltimore Ecosystem • Assessing spatiotemporal variations of greenness in the Baltimore-Washington corridor area Tang, Junmei Co-Authors: Fang Chen, and Stuart S. Schwartz • Communicating patterns of soil lead contamination to the public health community: the role of spatial models. Schwarz, Kirsten Co-Authors: Kirsten Schwarz, Steward T.A. Pickett, Richard G.Lathrop, Kathleen C. Weathers, Richard V. Pouyat and Mary L. Cadenasso • Correlating spatial heterogeneity in diurnal eddy fluxes with remote sensing and land cover during the growing and non-growing seasons in suburban Baltimore Saliendra, Nicanor Co-Authors: John Hom, Rich Pouyat, Matt Patterson,Ian Yesilonis, Gordon Heisler and Dave Nowak • Does spatial configuration matter? Understanding the effects of land cover pattern on land surface temperature in urban landscapes Zhou, Weiqi Co-Authors: Ganlin Huang, and Mary L Cadenasso • Is everyone hot in the city?: spatial pattern of land surface temperatures, land cover and neighborhood socioeconomic characteristics in Baltimore, MD Huang, Ganlin Co-Authors: Weiqi Zhou and M. L. Cadenasso • Spatial patterns analysis of multiethnic settlement in Lijiang City, China Lin, Tao Co-Authors: Tao Lin(presenter), Ling Feng, Xianhua Guo, Jingzhu Zhao • Spatio-temporal heterogeneities in mosquito communities and vector-borne disease risk in an urban landscape LaDeau, Shannon Co-Authors: Shannon LaDeau and John Wallace

  10. GIS @ Andrews • Andrews Website: • For each study site, you get a Google map of the sites, and a link to more info. All database driven. (access through the data pages on the Andrews website) • Digital Forest: • The objective of this project is to spatially model current forest structure and composition of the Andrews. • Digital Forest Link

  11. GIS @ LTER IMC Phase 2… in development, image coming soon

  12. Geospatial Analysis Committee • Charged by Executive Board • Members include PI’s • Broader look: Acquisition of large data sets, analysis tools. • Jamie Hollingsworth and Theresa Valentine represent the GIS Working Group (and IM) on this committee • First Effort: • Working with SDSC center (Opentopography.org) on storage/access to LiDAR data for LTER sites.

  13. GIS Working Group • We try our best to fill the niche in the IMC related to Geospatial data and GIS technologies. • Accomplishments to date: • SiteBites GIS addition and several notes/articles, LTER GIS Base Data Standard, LTERMapS application, FGDC2EML stylesheet, input to EML best practices, workshop history at ASM, GIS surveys. • Our current foci have been on better management standards for geospatial data as it relates to the NIS, and dissemination of those data through online media. • FGDC2EML • LTER MapS update • GeoNIS introduction • Coordinate with new Geospatial Analysis Working Group • These are the needs we see… what else can we help with? • Training opportunities? • Other? Help us help you.

  14. Future Directions • Finalizing TOR • Document LTER GIS best practices • Fall IMC / EIM Birds of a feather x2 – September • LTER MapS Product Oriented Working Group – October • GeoNIS Workshop – Jan/Feb • ASM – 2012 • Propose another GIS issue of Databits (fall 2012) • Respond to training/workshop calls

  15. Membership/Resources • Open to anyone interested • GIS@lternet.edu mailing list • Adam Skibbe, Chair • Meeting informally @IMC in Santa Barbara • IM web portal pages: GIS Working Group pages • We can help with specific requests.
