advise on GIS softwa SAS/GIS or other vendors

Post by Douglas.Mc » Wed, 18 Oct 2006 02:22:53


I am now working in the health care industry.

I need to make some "pretty" maps, i.e.,
1) which show some minimal geo features e.g., highways
2) which plot "custom" areas (coverage of our hospitals) beyond simple
"ground zero" + radius based circles
3) which can calculate actual highway distance (provider to patient
zip to zip) rather than the "great circle" distance approximations.

Do you have any advise on GIS software, i.e.,
SAS/GIS
ESRI products: ArcView, Arc/GIS, BusinessMAP, etc
SAS Bridge to ESRI
MapPoint
MapInfo
DeLorme Xmaps
Maptitude

We do not have SAS/GIS & it's not obvious from Sas.Com what it adds to
SAS/GRAPH map making.

I attended an Arc/GIS version 9 release demo & it seems to have a
MAJOR learning curve, is overkill for our purposes, and rather high cost.

I've looked on SAS-L but found very limited info when searching on ESRI.

Doug:

Some thoughts on your needs. Prior to 2002 Microsoft included a mapping
program with Excel. It was useful but lacked super details. I recall a
highway map. If you wanted lots more detail you could buy a very
reasonable addition from the map software co in Troy,NY - MapInfo. This
will far exceed your needs.

Excel 2002 and later works with the above created files but doesn't have
a map program. Instead - as you might guess -Microsoft is pushing the
own program MapPoint. This will exceed your needs. It's got lots of
programming bells and whistles. There is a free trial version (2
CDs)from Microsoft see
http://www.yqcomputer.com/
http://www.yqcomputer.com/

I also notice something about a developer version. If it's like some
other MS developer software it's free. Developer
copies can be used on 1 PC for development without a time limit. MS
SQL-2000 and MS SQL-2005 have free developer copies. The free versions
are not widely publicized. E-mail me if you want them.

SAS easily exchanges information to and from Excel.

Doug,

With just SAS/GRAPH you can:
1) show some minimal geo features, and
2) plot "custom" areas.

However:
2a)creating a map of "custom" areas is somewhat more difficult. If you
can define your "custom" areas as conglomerations of existing map areas
(e.g. census districts or counties etc.) then it's not particularly
difficult using Base SAS and SAS/GRAPH. If not, you need some kind of
GIS software plus, of course, a draughtsman or cartographer.

Also:
3) calculating actual highway distances - is best done with either GIS
software or SAS/OR procedures (it's a network problem). With
difficulty, you could do it with Base SAS, but I would advise against
it. - Is it possible your requirements would expand from simple
distances to optimised routes?

I haven't used any GIS software recently so can't advise on particular
software, except to note that products tend to be either overkill or
lacking some capability that is a basic requirement.

Good luck!
Dave.

All GIS programs add the ability to handle 'layers' on your map.
You're interested in point features (like the location of each hospital)
and line features (like streets to the hospitals) and area features
(like the coverages of the hospitals). Each of these would be a
separate layer (or more than one layer). The GIS features will
add in the ability to work with these layers and to 'connect'
the layers in meaningful ways.

I'm not familiar enough with SAS/GIS to be able to tell you if it
will do everything you want. It will do most of the things on
your list above. Maybe even all of them.

ARC/INFO and ARC/GIS are probably overkill for your purposes.
If you want an ESRI product, look at ArcView, which is more
point-and-click, and has an easier learning curve. ARC/INFO
has a learning curve that makes the SAS learning curve look
like a flat line with slope near zero. :-) ArcView will still set you
back about $1500, although you can get an eval CD from ESRI.

Or you could try GRASS, which is a popular free GIS program.
It won't integrate with SAS data as well as SAS/GIS, and it
doesn't have a 'bridge' to SAS like ESRI's ARC/INFO does,
but it's a full-featured GIS.

HTH,
David

i Douglas,

In that case, I would strongly recommend a real GIS software. I use SAS and
ArcGIS but honestly I don't think it's worth the money to get the SAS/ESRI
Bridge. I listened to the vendor for 30min but I just wasn't convinced it's
worth the extra bucks. Since the data in shapefile are in dbf format, I
usually just do whatever manipulation I want in SAS and replace the original
dbf file.

I use Maptitude too. Some of its extensions (e.g. redistricting extension)
are neat but personally I think it's GIS capabilities still lag behind that
of ESRI...Plus Maptitude doesn't use .dbf as default which makes it
incovenient to transfer data to SAS for manipulation.

If what you need is some simple overlays, you may want to try ESRI's free
software, ArcExplorer. It doesn't do as many cool tricks as ArcMap though.

You mentioned about highway distance. If you need an accurate measure of
road/traffic distance or traffic-time distance, then you should look into an
ESRI extension 'Network Analyst'. The latest version (integrated with
ArcMap)9.1 can do many tricks which were once limited to ArcInfo. (The
learning curve for ArcInfo is really steep ....) ArcMap is more user-friendly.

In addition, if you're thinking about 'service area', instead of drawing
area based on a fixed radius, you may consider drawing area based on road
network distance. These are some really neat tricks in 'Network Analyst' too.

In short, my suggestion is: go for ESRI product. But spend your bucks on
extensions like Network Analyst and not on ESRI/SAS Bridge. :-)

AS/Gis has been a joke, in any and all incarnations that i've examined it. For a somewhat less expensive and VERY analytically oriented package, you might try Idrisi out of Clark University. Also ArcMap/View/etc. has become a defacto standard...but, like SAS, you have to pay an annual license fee (though that's only to get suppor and upgrades..it doesn't stop your existing copy from running)
