The GeoVu project was initiated at the National Geophysical Data Center (NGDC) in 1990 to simplify access to diverse data. GeoVu was developed with funding support from NOAA's Earth System Data and Information Management (ESDIM) Program.

GeoVu addresses several barriers to data access:
With GeoVu you can view a number of widely used data formats, of both image and point data. You can:
Data Supported by GeoVu
The data files can be organized in an easy-to-read and sensible hierarchical fashion using menu files that control access to the data without being limited by the local file system and arcane file naming conventions. You can also easily associate metadata -- such as text descriptions -- with individual or groups of data files.
GeoVu can display any data type that can be described by a FreeForm format. GeoVu also provides built-in support for the following data types: GIF, BMP, PCX, AVHRR_GAC_1b_unpacked, Binary_raster, ERDAS_raster, GEOVU_raster, IDRISI_raster_version3, IDRISI_version4, McIDAS_PC_IMAGE, McIDAS_UNIX_IMAGE, Modified_DTED_DEM_format.
GeoVu does not support hierarchical formats like HDF or NetCDF, though there are tools which can convert these formats to ones GeoVu can read.
To use the Sampler data, copy the sampler.men file to your GeoVu directory, then when you open Sampler data, you will need to specify the directory in which the gvdata directory was created after downloading. In other words, you will need to type something like:
GeoVu is now available for four platforms. Details on obtaining and installing GeoVu on each platform are available in the following documents:
