(57) The 1:1250 and 1:2500 datasets contain link/node elements and cover 4%
and 86% of the national area respectively. The 1:2500 dataset should be
completely available by 1997. Both datasets are continuously updated.
The 1:10 000 and 1:100 000 topography datasets should also be completely
available by 1997. The 1:100 000 was produced through generalization.
The 1:10 000 is known to be continuously updated.
In addition to contours the 1:50 000 and 1:250 000 datasets also cover
hydrology, coastlines and boundaries. The 1:250 000 also covers
communications and settlements. The 1:50 000 contains vectors, seeds,
feature codes, names and INS-codesand the 1:250 000 contains vectors.
The datasets cover the national area and both should be completely
available. The 1:50 000 is continuously updated and the 1:250 000 is
updated irregularly.
All datasets use the Irish Grid coordinate system.
Costs for most of these data sets can be arranged through a bilateral
agreement.

DEM SOFTWARE
------------
(A) Peter Guth has developed a super little PC-based program for DEM Mapping
and analysis called MICRODEM+ which is freely available. MICRODEM+ reads
USGS, DMA DTED, NOAA EEZ, TerraBase and ASCII xyz DEM formats, in addition
to satellite image data (TIFF, LandSat and SPOT) and map data in USGS DLG
or US Census Bureau TIGER formats. It forms an impressive geomorphometric
toolkit. Contour, slope, aspect and concavity/convexity maps can all be
produced (with several different slope and aspect algorithms), along with
cross-sections through to 3D perspective displays, with overlain thematic
data and fully animated fly through capabilities. Semi-variograms, fast
fourier transforms, statistical slope orientations, frequencies, basin
delineation are all possible. On top of all of that, the effects of
different map projections can be demonstrated and even animated
continental drift simulations are included. Demonstration data is
provided. There are also other programs including TS-PLOT and, for
oceanography, WAVES, TIDES, DUCK beach profiles and MARINE GEOLOGY.
These programs are all available via anonymous ftp from ftp.nadn.navy.mil
(Numeric IP address is 131.121.163.70), in the pub/oceano directory. Then
choose either the microdem and oceanlab directories.
A version is also available via Sol Katz's ftp site at URL:
ftp://ftp.blm.gov/pub/gis/microdem.*
(That is anonymous ftp to "ftp.blm.gov" and it is in the directory
"/pub/gis/", called "microdem.xxx", where xxx is the version of the
software).
Peter will be adding additional programs, data and documentation as time
goes on and providing updated versions of the programs. He is interested
in suggestions, comments and ideas on how to improve the programs.

(B) Kevin Wooley has produced a shareware package called 'Landscape Explorer'
running on a Windows PC (with at least 4MB RAM). Version 3.50 is new in
October 1995. It can import data from digital files or scanned map images
(allowing you to automatically trace contours) to create 3D models of
landscape surfaces. These can be viewed from any position and drawn in
many different schemes such as Summer and Winter colours, GIS data mapping
and wire frame. Supports USGS DEM 7.5' (provided they conform to the
official format of blank-padded and CRLF-terminated 1024-byte records)
and UK OS NTF LandRanger file formats. Version 3.0 adds a much enhanced
user-interface, animation, 256 pseudo-realistic colour schemes and
"state-of-the-art" interpolation facilities. I'm told it doesn't handle
very large grids, and that the unregistered version allows only 16 colors,
and an even smaller grid.
In addition, a new program called Landscape Animator allows the creation of
views from inside the overlay and the generation of fly-throughs. A small
demonstration file available via Kevin's home page (see below) shows a
flight up the south col of everest using the Royal Geographical Society
'Hollings' map.
You can get the software via ftp to "garbo.uwasa.fi" as
"/windows/graphics/land350.zip" or "oak.oakland.edu" in the directory
"SimTel/win3/gis". The software is also available via Kevin's home
page at http://www.stir.ac.uk/~kjw1r/home.html
The shareware registration costs GBP40/US$65. A non-shareware 'pro'
version is also available that includes image and object overlay
facilities, AutoCAD DXF export and VistaPro interfaces.

(C) Sol Katz (sk...@dsc.blm.gov) maintains an archive of GIS programs and some
data which accessible via ftp to "ftp.blm.gov" in the directory "/pub/gis".
The files which are relevant to terrain modelling include:
000-index Index File
contour.zip f77 src for contouring a grid
dem2dat.zip convert dem to xyz, qb src and exe
dem2xyz3.zip convert dem to xyz, c src and exe, works on 3 arc-sec, v3

demout.f77 create a usgs dem from a grid. f77 src
nyc.dxf contours (20') of west half of New_York_e.dem, lat long
renka.f77 point triangulation to grid, f77 src only
There are also a number of different PC-based GIS packages and lat/long
<-> UTM inter-conversion programs.
(D) SAGE Capture is a program running under DOS windows (with command
buttons). It translates between a variety of raster and vector file
formats including export filters to VistaPro DEM and BIN formats.
With the vector to raster converter you can create raster point/line,
polygon and DEM surface maps from vector DXF data. These maps, once
created in raster format, can then be transferred to a variety of other
raster systems, including Arc/info grid ASCII, IDRISI, ERDAS .gis,
TerraScan, PC-MAP, SAGE, VistaPro, ASCII and CSV.
Another utility allows conversion of a landcover map to a VistaPro
terrain type overlay, which can then be used to have VistaPro render
trees, rivers, cliffs and buildings in the correct place on the DEM.
SAGE Capture is US$200 for academic institutions. For more information

(E) Ruediger Koethe has a program called SARA which can compute morphometric
relief parameters such as slope, aspect, curvature and analytical
hillshading from a DEM. It is also able to automatically derive
geomorphographic features:
- (linear) flow lines, crest lines, breakes in slopes (edges) and
- (areas) summit areas, valley grounds, slope areas, closed depressions,
areas with divergent and convergent flow paths, subdividing of
slopes etc.

SARA runs under VMS, SunOS and OSF/1 (with other UNIX versions planned for
next year). There is a nominal charge of DM 300. The user interface, the
online documention and the user manuals (approx. 200 pages) are currently
only available in German.

(F) ANUDEM has been designed to produce accurate digital elevation models with
sensible drainage properties from comparatively small, but well chosen
input data. ANUDEM calcuates values on a regular grid of a discretized
smooth surface fitted to large numbers of irregularly spaced elevation
data points, contour line data and stream line data. The program imposes a
global drainage condition which automatically removes sinks where
possible.
ASCII, Arc/Info and IDRISI formats are read directly. Output DEMs may be
written as either as a lattice or x,y,z in both ASCII and
Arc/Info-compatible formats.
The program is written largely in FORTRAN 77 and is normally distributed
in binary for SUN UNIX and DOS Windows platforms. Where these platforms
are not supported, FORTRAN source code may be supplied to academic
institutions.
The cost of a single-site licence is AUS$1000 (US$750) or for academic
institutions AUS$600 (US$450).

(G) Richard Horne has developed a freeware program called 3DEM for Windows 95
and Windows NT. 3DEM version 3.0 provides landscape visualization and
flyby animations from USGS DEM files (including Arc/Info DEMs), Digital
Chart of the World (DCW) files, NASA Mars Viking Orbiter Digital Terrain
Model files, or any topographic data file which consists of a matrix of
elevation data arranged by row and column.
3DEM ray traced landscape images are produced with complete colour control
including artificial illumination as well as colour scaling by elevation.
3DEM will also produce red-blue 3D images for viewing with 3D glasses.
Animations can be created to give a realistic fly-through view of the
chosen landscape.
3DEM version 3.0 is available at the following locations:
ftp://ftp.winsite.com/pub/pc/win95/desktop/3dem30.zip

There are many fewer packages which support true 3D functionality in a
GIS-related environment is:
Dynamic Graphics IVM (Interactive Volume Modeller)
Intergraph MGE Voxel Analyst
Stratamodel Stratigraphic Geo-Cellular Modeling System
MINESoft Techbase
Eric Miller keeps information regarding volume visualization packages
(including pointers to additional information, hardware platforms, etc.).
This can be found at URL http://www.oclc.org:5046/~emiller/misc/volvis.html.
It is usually difficult to get a connection to this server, and even if a
connection can be obtained, my experience is that, data transfer can be slow.
