ESRI User Conference 2000
From the Floor - "Wednesday's Summary"
by Glenn Letham
Hello once again!
When I concluded yesterday’s report I immediately
raced off to a meeting with Roger Tomlinson.
I’m not
going to go into too many details at this time, but I
will say that I had a very captivating hour and a half
discussion with the man who’s ideas, theories, and
dedication to the field of geography gave root to what
we now refer to as GIS.
He walked me through a
timeline of GIS, commencing with the work he did in
the 60’s establishing a digital land base in Canada
known as the Canada Land Inventory. He shared stories
of his experiences consulting on GIS projects in many
parts of the world, including South America,
Australia, and the US.
Dr. Tomlinson was very excited
to discuss GIS in education, particularly regarding
the mandatory GIS curriculum that now exists in the
Ontario school system. He made a point of making sure
that I understood that he sees geography not merely as
a discipline, or science, but that it is an idea...
But, enough for now. I’ll
be summarizing my entire fascinating discussion with Dr.
Tomlinson in a "feature" article at
a later date.
After discussing the past history of GIS with
its founder, ironically, I then proceeded to a session dedicated
to the FUTURE of GIS.
ArcPad 5
Shane Clark, ESRI’s ArcPad
product manager hosted an intro to ArcPad 5...
a product that he billed not as stand alone product but
an extension to ArcView, ArcInfo, and ArcGIS.
The
product is designed to meet the needs of those
who require real-time data
capture capabilities, as well as the ability to edit,
update, and query GIS data in the field.
ArcPad has
been developed for the non-GIS end user and thus,
offers a very easy to use interface that users can
quickly get up and running in the mobile and wireless
computing environment.
ArcPad took it's roots from a
product developed in 1995 known as MapPad. The first
version actually ran on the Apple Newton platform and was
subsequently ported to the Windows CE environment in
its third version released in 1998.
ArcPad runs on Windows CE devices. Clark gives the
following reasons for selecting the Windows
CE platform, which reportedly has no more than 20% of the market
share:
- 32-bit multi-tasking
- Fast CPU processing
- 32 MB on board memory
- Good screen color and size
- Compact flash card
- Similar interface to Windows
Windows CE devices that support ArcPad include:
- Palm size devices
- Handheld PC’s
- Ruggedized PC’s
- Laptops
- Pen tablets
- Field PC’s
- Cell Phones
ArcPad requires
Windows CE 2.1 or later and reads SHP formatted vector data (points,
lines, and polygon data types are all supported), as
well as MrSID, JPEG, BMP, and CADRG raster data.
It should be noted that raster data must be referenced using a World file and
must be either 8 or 24 bit data. This version does a
good job supporting multiple map projections and also
has some built in metadata management capabilities.
For real time data capture, ArcPad supports GPS
receivers that follow NMEA, TSIP, or Delorme Earthmate
protocols. In the US, this means you can use TSIP,
Ashtech, or Magellan GPS units. ArcPad will interface
with your existing systems using a cradle, modem
connection, or LAN card.
To export existing data from ArcView, an extension
known as ArcPad Tools is available. Users can easily
select data from SHP files (or entire PRJ files) and
export to an APP project, which can then be accessed
from a Windows CE device running ArcPad.
ArcPad Tools
also enables form creation so that field users can
easily enter data without fussing about database
design.
New features to come in ArcPad 5.0.1:
- Free upgrade for existing users
- Support for pocket PC
- Enhanced GPS support
- Improved form and find tools
- Longer evaluation time
The upcoming version 5.1 promises to include an application
builder, enabling developers to customize ArcPad using
plug in dll’s. The ArcPad Beta program will commence
this August. The final release for ArcPad 5.1 is
tentatively set for late 4th Quarter 2000.
Clarke left off by encouraging wireless developers and
business partners to develop add on products and
extensions for ArcPad. All in all, I found ArcPad to
be very simple to use and I can confidently state that
I could immediately return to the office tomorrow, get
my ArcView data onto a CE handheld device and take it into
the field!
I was very interested to find out that ArcPad actually
takes it roots from a company in Australia known as
R.I.A TerraSystems. I met the development crew from
R.I.A and they graciously filled me in on the history
of their company and road they took to make ArcPad a
reality. The guys from down under were a real pleasure
to talk to and I had a great time discussing the
mobile computing business with them as we took in the
festivities and a couple of beers at a corporate party
on Wednesday night.
The rest of my day was spent meeting several hundreds of
people at our booth and distributing the ever-popular
GeoCommunity T-shirts to the swarms of people crowding
around our booth. No doubt, we definitely have the
most popular freebie once again!
Also, the crew at
Lizardtech gave me the low down on their free image
viewing software and their latest product called DjVu
(pronounced deja view). DjVu was very cool and is an
excellent must-have tool for engineering
companies, local government, and other users who need
to web-enable vast quantities of plans, maps, or other
scanned documents.
A special thanks to Lizardtech also for the
excellent hospitality they showed us and a couple of
hundred others at their corporate bash yesterday
evening. The party was well coordinated and
held on the deck overlooking the beautiful harbor.
