			Multi-dimensional Spatial Datablade Module

				MdSpatial.1.0

----------------------------------------------------------------------------
[Created November 1999]
[Original Author	Steve Kelley	skelley@umiacs.umd.edu]


	This Spatial Datablade module, based on both the Informix Shapes2
datablade module and on Rtree software developed by the original author,
provides multidimensional spatial (opague) types for the Informix Universal
Server.  It also provides the methods required by Informix to create and
maintain spatial (rtree) indexes, and various cast and type constructor
functions.

1) Software Requirements
   =====================
	To build and run MdSpatial.1.0, you need a C compiler that can build
a shared object and link it with Informix and the Informix Dynamic Server
with Universal Data Option (IDS-UDO) release 9.14 UC2 or higher.

	MdSpatial.1.0 was tested with the systems and software releases
listed below:

	SGI:
		IRIX 5.3
		IDS-UDO 9.14.UC2
		C compiler

	SUN:
		Solaris 2.5.1, 2.6
		IDS-UDO 9.14.UC2
		SUNpro, GNU C compilers

2) Getting Started
   ===============

Check/Initialize Your Informix Environment
------------------------------------------
	Make sure the following environmental variables are set correctly:
INFORMIXDIR	directory where Informix was installed
TARGET		$INFORMIXDIR/incl/dbdk/makeinc.solaris
