1. Annual Site Byte

Information Management
Ken Ramsey and Barbara Nolen have been planning on how to effectively integrate GIS data layers and research site locations with research data and associated metadata to enhance the quality and availability of all JRN data and to generate more detailed and precise EML documentation.

Barbara continues to provide GPS of research site locations and production of new GIS layers, to provide GIS and GPS support to researchers and students including training and map production, and to administer NMSU site licenses for GIS/RS software.

Ken is currently populating the JIMS database with research project and associated dataset metadata to support EML generation for all Jornada Basin LTER (JRN) datasets as well as the new dynamic data catalog and data cart that will enforce the JRN data policies for download notification using a user registration system that is in beta testing. This process includes validating data structure consistency between data and metadata.

Database Server
The USDA ARS Jornada Experimental Range (JER) purchased a new database server and the JIMS’ databases and Trends administrative databases have been migrated to the new server, which required upgrading from Microsoft SQL Server 2000 to 2005. During this process we discovered that Xanthoria (CAP LTER product) would not work on SQL Server 2005. This required that we develop a customized EML creation solution from metadata stored with JIMS. New style sheets have been developed that generate EML level 3 from the JIMS database.

Integrating GIS Data, Metadata, and Services
The GIS metadata in xml will be used to generate EML documentation for all JRN GIS layers stored within JIMS, which includes geographic bounding coordinates within EML documents describing research datasets.

JRN purchased a new server to support ESRI ArcGIS Server and ArcGIS Image Server software to allow JRN researchers to query and access the JRN data, GIS layers, and imagery. Ken and Barbara attended the Annual ESRI International User Conference in San Diego, CA to gather technical information necessary to develop and serve the GIS services on the new GIS Server. The new GIS Server will support the following GIS Services:
• query and access to aerial photograph archive
• access research site locations (Intranet)
• online shapefile production to support research site location selection and approval
• Jornada Interactive Map (2D) on website
• Jornada Interactive Map (3D) using ArcGIS Explorer

Deployment of ESRI ArcGIS Explorer is being evaluated to support interaction with the globe services and research site locations and their associated data and metadata as well as GIS thematic layers such as vegetation, soils, and base maps.

Jornada Website
The new web server (purchased by JRN) has been installed and configured to support the new Jornada website currently in beta testing. The new website will include a new XML-based data catalog and data cart that will enforce the JRN data access policy by requiring user registration and authentication prior to download of JRN data. Users that download data will be required to supply an intended use statement upon download. Users will provide contact information, affiliation, and acknowledgement of the JRN data policies when they register with JIMS. When the beta testing of the new website is completed, the new server will be renamed and replace the web server that currently serves the Jornada website.

2. Planned IM Projects

1. Data:
a. Production of Chihuahuan Desert Landforms map
b. Update Desert Project map data
c. Review and update metadata for legacy research datasets
d. Upload legacy dataset files into databases (JIMS and ArcSDE) and correct any problems discovered while moving from ASCII text files to RDBMS
2. EML:
a. Generate EML level 3 for all Jornada datasets including GIS layers (soils, vegetation, etc.)
b. Enhance style sheets used to create EML to generate EML level 5 (attribute information).
c. Implement and enhance the esri2eml style sheet to create EML for GIS layers and incorporating research site location bounding coordinates within research dataset EML documentation
3. JIMS:
a. GIS Services:
i. Incorporate vector drawing functionality to website to give prospective researchers at the Jornada the ability to draw proposed research site locations on the Jornada base map to aid in selection and evaluation of impact of proposed research on nearby ongoing/historic research efforts for approval/disapproval.
ii. Spatial and tabular query interface to aerial photograph archive
iii. Information management notification system
b. Develop research notification administrative and user interfaces
c. Develop automated dataset tracking system
d. Implement QA rules for dataset attributes within metadata and enforce when uploading research data to JIMS database
e. Consistently document and implement QA rules and flags within JRN research dataset documentation and JIMS databases and interfaces
4. Systems and networking:
a. Upgrade to ArcSDE 9.2 on Database Server
b. Upgrade to ArcIMS 9.2 on the Map Server.
c. Deploy development server as new web server to add new data catalog and cart functionality
d. Extend wireless coverage in the field
e. Increase storage capacity for imagery using SAN/NAS solution
