for alex goetz you might try contacting them if you already have idl or would be willing to buy it it s a few thousand dollars american i expect for idl and the other should be free those are the general purpose packages i ve heard of besides what terramar has sips was written for aviris imagery i m not sure how general purpose it is you would have to contact goetz or one of his people and ask i have another piece of software pcw that does pc and walsh transformations with pseudocoloring and clustering and limited image modification you can compute an image using selected components i ve used it on megabyte aviris images without problems but for the best speed you need an external dsp card it will work without it but large images take quite a while times as long to process that s a freebie if you want it my favorite is idl interactive data language from research systems inc idl is in my opinion much better and infinitely easier its programming language is very strong and easy very pascal like it handles the number crunching very well also personally i like doing the number crunching with idl on the vax or mathematica igor or even excel on the mac if it s not too hairy then bringing it over to nih image for the imaging part i have yet to encounter any situation which that combination couldn t handle and the speed and ease of use compared to iraf was incredible by the way it s mostly astronomical image processing which i ve been doing this means image enhancement cleaning up bad lines pixels and some other traditional image processing routines then for example taking a graph of intensity versus position along a line i choose with the mouse then doing a curve fit to that line which i might do like in kaleidagraph for idl call research systems for pv wave call

of gis software hardware microstation is a base graphics package that imager sits on top of imager is basically an image processing package with a heavy gis remote sensing flavor feature description basic geometry manipulations flip mirror rotate generalized affine rectification affine nd rd th and th order models as well as a projective model warp an image to a vector map or to another image rgb to ihs and ihs to rgb conversion principal component analysis classification k means and isodata fourier xforms forward filtering and reverse filters high pass low pass edge enhancing median generic complex histogram contrast control layer controller manages up to images at a time user can extract single bands from a band image or create color images by combining various individual bands etc the package is designed for a remote sensing application it can handle very large images and there is all kinds of other software available for gis applications host configuration requirements it runs on intergraph workstations a unix machine similar to a sun though there were rumors there are always rumors that the software would be ported to pc and possibly a sun environment pci a company called pci inc out of richmond hill ontario canada makes an array of software utilities for processing manipulation and use of remote sensing data in eight or ten different industry standard formats lgsowg bsq landsat and a couple of others whose titles i forget the software is available in versions for ms dos unix workstations among them hp sun and ibm and vms and quite possibly other platforms by now i use the vms version the pci software consists of several classes groups packages of utilities grouped by function but all operating on a common pci database disk file the tape i o package is a set of utility programs which read from the various remote sensing industry tape formats into or write those formats out from the pci database file this is the only package i use or know much about other packages can display data from the pci database to one or another of several pci supported third party color displays output numeric or bitmap representation of image data to an attached printer e g an epson type dot matrix graphics printer you might be more spe cifically interested in the mathematical operations package histo gram and fourier analysis equalization user specified operations e g multiply channel by add channel and store as channel and god only knows what all else there s a lot i don t have and don t use these so can t say much about them you only buy the packages your particular application interest calls for each utility is controlled by from one to eight parameters read from a common parameter file which must be in vms anyway in your default directory some utilities will share parameters and use the same parameter for a different purpose so it can get a bit confusing setting up a series of operations the standard pci environment contains a scripting language very similar to ibm pc basic but which allows you to automate the process of setting up parameters for a common complicated lengthy or difficult series of utility executions in vms i can also invoke utilities independently from a dcl command procedure there s also an optional programming library which allows you to write compiled language programs which can interface with read from write to the pci data structures database file parameter file the pci software is designed specifically for remote sensing images but requires such a level of operator expertise that once you reach the level where you can handle r s images you can figure out ways to handle a few other things as well for instance the tape i o package offers a utility for reading headerless multi band what adobe photoshop on the macintosh calls raw data from tape in a number of different interleave orders this turns out to be ideal for manipulating the graphic arts industry s ct t format would probably i haven t tried handle targa and so on above all however you have to know what you re doing or you can screw up to the nth degree and have to start over it s worth noting that the pci database file is designed to contain not only raster image data but vectors for overlaying map information entered via digitizing table land use and all manner of other information i observe that a remote sensing image tape often contains all manner of information about the spectral bands latitude longitude time date etc of the original satellite pass all of this can go into the pci database i believe that on workstations the built in display is used on vax systems other than workstations pci supports only a couple of specific third party display systems the name gould deanza seems to come to mind one of my personal workarounds was a display program which would display directly from a pci database file to a peritek vct q q bus bit directcolor display subsystem pci software could be overkill in your case it seems designed for the very high end applications users i e those for whom a mac pc largely doesn t suffice although as you know the gap is getting smaller all the time it s probably no coincidence that pci is located in canada a country which does a lot of its land resource management via remote sensing i believe the canadian government uses pci software for some of its work in these areas spam spectral analysis manager back in jpl developed something called spam spectral analysis manager which got a fair amount of use at the time that was designed for airborne imaging spectrometer imagery byte data pixels across by lines by bands a modified version has since been developed for aviris airborne visual and infrared imaging spectrometer which uses much larger images spam does none of these things rectification classification pc and ihs transformations filtering contrast enhancement overlays actually it does limited filtering and contrast enhancement stretching spam is aimed at spectral identification and clustering the original spam uses x or sunview to display the aviris version may require vicar an executive based on tae and may also require a frame buffer i can refer you to people if you re interested pcw requires x for display map ii among the mac gis systems map ii is distributed by john wiley clrview clrview is a dimensional visualization program designed to exploit the real time capabilities of silicon graphics iris computers this program is designed to provide a core set of tools to aid in the visualization of information from cad
