Services and Expertise
We provide clients with geographic information systems (GIS) services such as geodatabase development, data conversion and creation, and especially spatial data analysis, interpretation, visualization, and presentation.
Our expertise is in building and integrating spatial databases in a GIS environment. We are also familiar with coupling these databases to numerical models of various kinds, primarily to solve problems or target solutions in a wide range of natural resource subdisciplines.
GIS data management and processing for the Midwest Regional Fish Habitat Partnership Assessment Project, 2010-2011
Description: GIS data inventory, data assembly, and geodatabase
construction for input to spatially explicit regression models to evaluate fish habitat for the midwestern US. This project is a subcontract for Downstream Strategies, LLC, in West Virginia. See the USFWS press release.
GIS analysis of blueway and greenway corridors in Lake
Michigan Coastal Area, Indiana, 2009
Description: GIS data inventory, data assembly, geodatabase
construction, establishing criteria for development of new data
layers based on client needs, map composition, and cartography.
Wetland geodatabase development, hydrologic modeling,
and GIS analysis, Henry County, Indiana, 2008
Description: Data preparation for three-dimensional variably
saturated groundwater model including site-specific digital elevation
model generated from multiple data sources including survey data,
spatially distributed soils and geologic unit synthesis for subsurface
mapping, research for model parameterization, and GIS analysis,
synthesis of model results, and data presentation for client.
GIS analysis of sand and gravel aggregate volumes, Noblesville,
Indiana, 2008
Description: Completed GIS-based analysis of the volume
of sand and gravel sediments at a site in Noblesville, Indiana.
Analysis included acquisition of data, conversion and generation
of spatially accurate GIS data sets, interpretation of boring logs
and conversion to digital format, interpolation of thickness surface,
volume calculations, interpretation, and report.
Terrain analysis and simulation of pre-development topography,
Greencastle, Indiana, 2007
Description: GIS data development, analysis of available
datasets, terrain analysis, development of three-dimensional terrain
models before and after site development, calculations of sediment
volumes, map composition, and cartography.

Meet Sally
Dr. Sally Letsinger is owner and principal researcher of GeodataBasics, LLC in Bloomington, Indiana, a small geographic information systems (GIS) consulting company. She also holds positions at Indiana University (IU), where she is a research hydrogeologist in the Center for Geospatial Data Analysis at the Indiana Geological Survey and an adjunct assistant professor in the IU Department of Geological Sciences.
Dr. Letsinger has over 19 years of professional
experience in applying an interdisciplinary background and analytical
skills to a wide range of natural-resource issues. She has both managed
and provided the primary technical work on many projects over the years
in the areas of using coupled GIS and numerical hydrologic modeling (both
groundwater and surface water) to guide prioritization of best management
practices or to delineate source-water protection areas; identifying remediation
approaches in abandoned surface (coal) minelands by examination of disturbed-land
hydrology; recharge-discharge area mapping; and determination of wetland
hydrologic function for restoration or mitigation banking.

You might as well meet Kirin, too
Kirin is a rescue dog from the Monroe County (Indiana) Humane Association Shelter, who joined Sally's family in 2004. He accompanies her most everywhere, and also has a keen sense of spatial relationships (or at least is always pretty sure where Sally is). When attending meetings with her, he'll usually give you a sniff, assess the liklihood that you'll give him a cracker, and then lie at Sally's feet for the duration.
