At the Northwest Alliance for Computational Science and Engineering , we specialize in making research databases available through web-based interfaces. Many of these databases contain biological data and usually include a spatial component. In addition to providing text-based query tools and results, we also create web-based mapping interfaces that integrate database contents, allowing the user to (1) visualize the data in context of their geographic location, and (2) query the map to return values from the associated database. We develop primarily in Perl and PHP and use a number of open source GIS tools, many of which are mentioned below. In addition to developing web-based interfaces, we also perform data cleaning, processing, manipulation, and analysis, mainly with ArcGIS but also using AMLs and/or GDAL and PROJ.4 to automate processing. MapServer Interfaces - Our MapServer interfaces run on a Linux server and are created completely with Open Source Software, including MapServer , PHP Mapscript , PHP , GDAL , PROJ.4 , and a host of useful libraries. National Forest Service Lichen Air Quality Monitoring Program [toggle description] For several years, NACSE has hosted the National Forest Service Lichen Air Quality Monitoring Program's database and web interface. We reworked the interface while adding recently collected data, and as part of the process created a more efficient database structure and implemented more advanced interactive mapping functionality. Through this interface you can query lichen air quality monitoring data from every USFS region across the United States, retrieving your desired data on a map or in tabular form. The mapping interface features a tiling scheme similar to Google Maps , and is driven by a combination of clientside Javascript/DHTML and PHP, PHP MapScript , PostgreSQL / PostGIS , and MapServer on the backend. As in other interfaces, we make use of tiled TIGER/Line data to provide nationwide base layers. IHN Virus Database Interface [toggle description] The Infectious Hematopoietic Necrosis Virus (IHNV) Database interface was developed in collaboration with the National Biological Information Infrastructure and the USGS Western Fisheries Research Center . Users can query specific virus-related disease data from salmonid fish in Alaska, British Columbia, Washington, Oregon, Idaho, and California. Results are displayed in tabular form and on an interactive map, both of which are highly customizable. A special feature allows users to compare viral genetic sequences from samples collected in disparate locations. The interface is database-driven, using PostgreSQL and PostGIS on the backend. Maps are generated using MapServer , and many of the base layers are rendered from TIGER/Line data .   Cryptogams of Olympic National Park     [toggle description] Cryptogams are mosses, lichens, liverworts, and other non-vascular plants. This interface allows the user to query a Sybase database of cryptogam records using an interface driven by QML . After choosing "Map Results," sites containing the selected records are plotted on an interactive MapServer interface on-the-fly. Sites can be queried in the mapping interface for information stored in the database. This interface also retrieves DOQ imagery from Microsoft's TerraServer on-the-fly via WMS , integrating the imagery with locally served layers. Instructions: Go to the Cryptogams in the Olympics query page. You will see four menus. Make any selection(s) you want. A good example is to select several items from the "Genus" menu, and leave all other menus set at "** all values **". Another good example is to select several watersheds, and leave all other menus set at "** all values **". Click the "Map Results" button. -- Oregon Topographic Map (DRG) Viewer [toggle description] Over 15 GB of digitized, georeferenced 7.5" topographic maps (DRGs) encompassing Oregon can be browsed, queried for metadata, and downloaded. LTER Interactive GIS Viewer [toggle description] This interface allows users to browse and query GIS map layers from several of the Long Term Ecological Research sites. Users can quickly switch among the various sites by selecting from the drop down menu in the title bar. Some sites are not yet included due to a lack of spatial data for their respective regions. Nongeoreferenced imagery viewer     [toggle description] This standalone viewer allows users to browse nongeoreferenced satellite imagery. In the example linked here, an AVIRIS flight line image from the Sevilleta LTER site is displayed. Spatial Data Workbench users will be able to preview any single image in the SDW catalog via this interface. Image metadata is read on the fly from the header file and displayed in the subtitle bar. -- AVIRIS Flightline Generator [toggle description] Personnel from the LTER Network Office needed a way to dynamically generate flight line reference maps from AVIRIS imagery header file information. This interface supports both UTM and Geographic projections, and allows the user to quickly generate reference maps for several LTER sites. ArcIMS Interfaces - Our ArcIMS interfaces run on a Solaris server. We have developed sites around both the HTML and Java-based viewer templates, mainly using JavaScript for customization of functionality and appearance. H.J. Andrews LTER Site [toggle description] This interface was developed years ago in ArcIMS 3.0. The H.J. Andrews LTER site is located east of Eugene, Oregon in the Cascades mountain range. A great deal of forest research is conducted at this site, and both researchers and managers wanted a Web-based interface that would allow them to browse map layers and retrieve information from the site. This is a mirror of the production site, which is located on an OSU College of Forestry server . Bottomline Density Management Study Area [toggle description] The Bottomline Density Management Study Area is located SW of Eugene, Oregon, and is the site of a multidisciplinary project examining how a wide array of variables are affected by varying varying degrees of stand thinning. Participating organizations include Oregon State University , USGS Biological Resources Division , USDI Bureau of Land Management , and the National Biological Information Infrastructure . This ArcIMS site provides access to a number of base layers and contains additional hyperlinked information for each density treatment type. Research data will be made available via this interface as they become available. The NACSE computing facility supports multiple platforms (Solaris, Linux, HP-UX, AIX, Win32, Mac OS X). Our GIS and database servers are powered primarily by Solaris and Linux (RHEL). We have the full ESRI ArcGIS suite installed on several Win32 workstations, and use Quantum GIS and JUMP GIS on our Linux desktop workstations. We also use GRASS and GMT on certain projects. We maintain non-spatial production databases in Oracle, Sybase, PostgreSQL, and MySQL, and spatial databases in PostgreSQL/PostGIS.
