• Challenges and opportunities that information
managers encounter with the increase in
demand and in volume of geospatial data and
integrating this data with research data
collected as part of field studies.
– providing access and analysis tools for large LiDAR
datasets
– documenting geospatial data within FGDC and EML
metadata content standards,
– developing and managing Citizen Scientist data,
– strategies to obtain study site locations and use
these locations to provide geographic searches
using mapping tools.
Challenges:
providing access and analysis tools for large LiDAR datasets
Documentation for spatial data into EML
Dealing with ocean data
Managing data (limnologists, not thinking spatially.. Get them thinking about it)
Juggling the different responsibilities, handle all the different data types
Integrating with other datasets (study site)
Looking for a version control system and serving up data
Annual over flight photos, geo-referenced, stitched together (20 years of annual
flights)
Provide better access to data
Uses web services to provide infrastructure for spatial data
Manage in database/then interact with it spatially
15 years of historical aerial photos, geo-referenced, organized
Storage capacity growth, double every year. (raster data), finding info out of all
that data
Climate integration, research plot locations
Collection of geodabases, (3) how to integrate and synthesis. Adding points to
spatial data.
Geo-reference the non-spatial data, have GIS expert, but not EML expert for
database.
Working with DEM’s, tools to help visualization in 3D, produce animations.
Data Management:
File formats/hardware/software:
Geodatabase
1. Web servers: Geojason/jason (australia), postGIS spatial database, point data with
Cassandra, point data in huge table, very fast: EML at collection level, goes into geonetwork, metadata system.
2. postGIS: call geoserver, exported into whatever type you want, exported on the fly
(zip files):
3. Arcsde on SQL 2008, database connections, moving toward ARCGIS server, web
services:
Automated methods for converting data from different projections/formats…?
need some tools, how to make the export of data automated so we don’t have to
store shape files, etc.
Rule set for point data, other data manual; lots of steps
Open Source: very large community to get address issues.
Moved SDE to PostGIS, version behind (postGIS)…
free and open source software foss4G (gathering of open source GIS people)
Geoserver for webserver, openlayers for application, use in any client (will talk to the
geoserver). ESRI web server with open source applications? Some success.
Backups: SQL dump, offsite storage, don’t back up non-changing data.
Non-data: processing speed, convenience, prefer to go to the source, managing
downloads on your site (duplicate data), too much data/inefficient storage?
3D software: ArcScene, 3D Architect, fusion, gaming software, others…

Develop Wiki to share information.
Lots of interest in Open Source GIS solutions.
Area of interest could be in developing methods to export/serve
data without having to store static files (shape files)
