Bathymetric data is often in one vertical datum and terrestrial elevations in another. You open the data in ArcGIS and hope that the on-the-fly projection takes care of things, only to realize it only works for the horizontal datum. Learn the steps necessary to convert LAS data from NAVD 88 to MHW, these methods could also be used for other vertical datum transformations.
Advancing Geospatial Solutions for Environmental Challenges
The Environmental Data Center is the center of technical expertise in GIS for the state of Rhode Island. The (EDC) is a Geographic Information System (GIS) and spatial data analysis laboratory in the University of Rhode Island's Department of Natural Resources Science, College of the Environment and Life Science. Major areas of research at the EDC are spatial data modeling, ecological mapping, and data integration for environmental applications.
The mission of the EDC is to support the use of contemporary tools of spatial data processing and electronic dissemination in the analysis and distribution of environmental data. This is achieved through collaborative research with faculty in the Department of Natural Resources Science and projects with agencies external to URI.

The USDA Geospatial Data Gateway is a great source for natural resources-related data and can be used to download pre-processed collarless topographic maps in MrSid format. This blog posting provides an alternative method for acquiring collarless topographic maps and helps to eliminate processing as stated in related blog postings.
Transform USGS Topographic maps from the GeoPDF format into a more GIS-friendly format - the GeoTIFF. GDAL, an open-source software program that has been specifically designed for use in reading and writing information to geospatial raster data formats. Find out how..
