		       README for ivmaps 0.6


This directory contains a release of the ivmaps 0.6.5 distribution
from Vectaport Inc..  You should read the rest of this file for
information on what ivmaps is and the INSTALL file for instructions on
how to build it.  It is known to build on SunOS 4.1.3 (MIT's X11R5,
gcc-2.7.2), Solaris 2.6 (X11R6), Irix 5.2 (SGI's X11R5, gcc-2.7.2),
Linux 1.2 (gcc-2.7.2, elf), and Linux 2.0 (RedHat 4.0 and 4.1).  There
is also a contributed config for HPUX.  You can pick up binaries for
some of these platforms from the ivmaps web page
(http://www.vectaport.com/ivmaps/).

* What is ivmaps?:

ivmaps provides facilities for map database access and display. It
builds on top of ivtools-0.6, PROJ-4.3, and optionally clippoly.  It
supports a variety of terrain databases produced by the United States
Geological Survey (USGS) and National Imagery and Mapping Agency
(NIMA).

These are the libraries that make up ivmaps:
	Map		library of Map access base classes
	MapUnidraw      library of Map display Unidraw-derived classes
	VpfUtil		utility library of vpf source code
	Vpf		library of Vector Product Format access classes
	Dlg		library of Digital Line Graph access classes
	Dem		library of elevation grid access classes
	DemVtk		library of elevation grid 3d objects
	Los		line-of-sight and viewshed library from DMAMUSE
	LosServ		losserv library
	MapServ		mapserv library
	VpfUnidraw	library of Vpf display Unidraw-derived classes
	DlgUnidraw	library of Dlg display Unidraw-derived classes
	UtmUnidraw	library of generic utm map feature display classes
	VtkUnidraw	library of Dem display Unidraw-derived classes

These are the map viewers in ivmaps:
	vpfviewer	VPF viewer
	dlgviewer	DLG viewer
	demviewer	DEM viewer
	utmviewer	2d map viewer with UTM projection

These are the map servers in ivmaps:
	mapserv		map feature class server
	losserv		line-of-sight server

These are the utility programs in ivmaps:
	dcwdemprint		
	usgsdem2vtk
	usgsdemprint
	vpfdbprint
	vpftableprint

To get a quick look at these, check out the ivmaps home page:
http://www.vectaport.com/ivmaps/

A series of makefile targets support the checkin of sources to
cvs/rcs, and their subsequent update and modification.  This requires
cvs (at least 1.3) available from the Free Software Foundation and
ivmkcm-0.7 available through http://www.vectaport.com/ivmkcm/

The VpfUtil library contains the public domain VPFVIEW C code included
with the Digital Chart of the World, Edition 1, which was pruned and ported
to work on "POSIX"-like systems.

The line-of-sight and viewshed capability was borrowed and retrofitted
from the DMA (NIMA) MUSE2 package.

ivmaps relies on the PROJ software package from the USGS and Gerald
I. Evenden (gie at kai.er.usgs.gov).

ivmaps was developed with partial support from IET Inc. (P.O. Box
112450, Campbell, CA 95011) in the form of ARPA subcontracts (Prime
Contract Number DACA76-93-C-0025 and DACA76-97-C-0005) to Vectaport
Inc. (P.O. Box 7141, Redwood City, CA 94063).
