¤ This page tells you about some of the free software that can display VMAP0 data.
Application software, called VPFVIEW V2.1, has been developed by NIMA and allows users the ability to access and view VMap Level 0 data. The software, available separately from NIMA or USGS within the DMAMUSE software package, has been developed to operate on a PC.
The VPFView software is designed to access any database implemented in the Vector Product Format (VPF) and allows data to be selected for display from one or more databases by geographic region and by data type. For example, you can zoom into a geographic area of interest and request a single type of feature, such as dual-lane highways to be displayed. Or, you can display a group of related features (e.g., all road types), combinations of feature types (e.g., dual-lane highways and international airports), or all features existing in the database. The software also allows you to display and evaluate the database directly from CD-ROM, hard drive, or other media without loading or converting the data (although you will pay a speed penalty when reading the data from CD-ROM or an equivalent media).
The VPFView software is not a geographic information system (GIS). The software is designed to enable you to view and perform spatial queries on data contained in any VPF database, but its analytical capability is limited to constructing views and themes.
Once you have generated a display, you can save the results of a data request as a graphic display (.bmp) or the text of a report. You can also save the data request itself, in the form of a 'feature selection list'. Selected libraries and coverages can be saved in a user-defined database.
Note: This software, whilst fully working, is no longer supported, and help queries are no longer answered. However it is well worth downloading, not least for the VPF-Shapefile converter. NIMA no longer carry this software on their site, so I have made it available here.
- Download the VPFView and NIMAMUSE software applications from my Download page.
- For frequently asked questions and answers visit the NIMAMUSE FAQ page.
- For a complete introduction to NIMAMUSE 2.1 visit the Documentation page.
- Additional information on VMap0, VFPVIEW 2.1, and DMAMUSE is available at the Publications page.
There are a number of alternatives to the VPFVIEW software. Listed below are five viewers that can read NIMA data and are available free to anyone via internet downloads.
- ArcExplorer is a lightweight GIS data viewer developed by ESRI. This software offers an easy way to perform basic GIS functions. ArcExplorer is used for a variety of display, query, and data retrieval applications and supports a wide variety of standard data sources, including VMAP0's VPF files. It can be used on its own with local data sets, or as a client to Internet data and map servers.
- MapInfo ProViewer provides a user the capability of sharing maps and information created by MapInfo Professional(r) with clients and co-workers.
- ERDAS ViewFinder is a free viewing tool that has basic image viewing and manipulation capabilities.
- Geomedia Viewer lets users create Thematic Maps using free sample data and then view and analyze the data in either Microsoft Access or Arc/View Shape format. Geomedia also provides the capability to load raster images and easily manipulate the images using its zoom-in, zoom-out capability.
- DLGv32 and DLGv32 Pro are Windows 95/NT software applications used for viewing USGS digital cartographic data. DLGv32 Pro is a limited-feature version of commercial software called Global Mapper which was created from the original DLGv32 source code. Unless the program is registered, ($124) you will be unable to export data to any format, limited to loading a maximum of 4 data files at a time, unable to load workspaces, unable to do line of sight calculations using loaded elevation data, and unable to perform view shed analysis using loaded elevation data. Both versions are also available from the FTP site.
