For those who are perhaps new to the advantages and uses for GIS, he listed a number of uses for the technology: fire departments using GIS for incident mapping and service area mapping; AAA using GIS for triptiks to help people plan vacations, crime mapping online, property value analysis; electrical utilities mapping distribution systems; transmission routing using GIS and much more.
GIS is also moving into some new areas such as "planetary geography" (an oxymoron since geography is about the earth, noted Dangermond) with the Jet Propulsion Laboratory in Pasadena using it to studying Mars and the moon.
According to Dangermond, GIS abstracts geography into five basic elements:
- Geographic data models
- Geodata sets
- Process and workflow models
- Map and globes
ArcGIS 9.0 has been released recently, characterized as a "complete system for GIS professionals." The product architecture includes servers, clients and mobile clients. Many of the new features, which include cartography, visualization, data interoperability, and geoprocessing, brought rounds of applause from the audience. "This component architecture is how we were able to build these three product families," said Dangermond. "with thick clients and thick servers, for mobile, and desktop."
Geoprocessing implements a comprehensive environment for spatial analysis. ModelBuilder allows you to build models and data tools and share them. 9.0 supports a complete system for raster data. Data interoperability is improved with this version as per standards adopted by the OGC, and consequently, CAD data is now integrated more closely with GIS. ArcGIS extensions enrich many specialities. 3D Analyst has many tools for advanced surface modeling and spatial analysis.
ArcGIS Publisher has a free embeddable map that you can put inside another application and zip up data in a high performance environment. Business analyst offers business focused applications and data sets. The Data Interoperability extension, designed in concert with Safe Software, supports complex data transformation.
For GIS networks to work, everyone uses same software, or they use interoperability procedures, Dangermond explained. Geoprocessing models can transform data automatically using the Interoperability Toolkit.
Network Analyst extension will be released in a few months which will include tools and applications for advanced network analysis. The example of how advanced network analysis would be beneficial was this demo: In Washington D.C., seniors' locations were collected and their distance to a nearest hospital. It was revealed that the city needed a new hospital to serve some of the seniors. The analysis tells you how many seniors are in each area and identifies where it would be good to build another hospital.
ArcPad 7.0 will be out in a few months, promising to be much faster, for field based geography.
9.0 Server Products
ArcSDE is a gateway to multiple DBMS systems. SDE has always been fast but scalability and performance has been added, and an XML version of the GML database has also been added. ArcIMS is a compete solution for map publishing, catalogs, and the Geo Portal Toolkit.
ArcIMS data download extension has enhanced server based interoperability, and a Mapquest routing extension. With the ArcIMS GIS Portal Toolkit, built with the support of the Geospatial One-Stop Program, you can build your own metadata catalog.
ArcGIS Server is GIS components for server developers. It has a powerful web developer kit in a simple web implementation. It can integrate with other systems at the application level, not the data level.
ArcGIS Engine is basically ArcObjects for developers, and has thousands of GIS functions and tools. It lets you build your own tools. There is a table which we will hear more about, where you can run the engine and building tools.
ArcGIS desktop development projects. ESRI is slowing down in this area, but adding more quality, more scalability, and performance - multiple layouts, data frames, layers, north arrows, easier editing with fewer clicks, faster drawing and printing, multiple viewer windows, and batch geoprocessing.
Intelligent cartography--a single environment for cartographic production, is provided with ArcMap. The ArcMap application is being extended for cartographic editing, extending geodatabase to support cartographic layers (persist geodatabase)
3D Analyst provides new tools for creating visualizing and serving, and can support 100 million points in LIDAR, with improved ArcScan, improved conversion tools, extended geoprocessing, additions to basic framework so it can deal with large datasets. It will work on the server, adding to spatial analysis tools, and also they have added temporal modeling and server based geoprocessing.
This was accomplished by managing multidimensional geographic data sets, which required extending the Data Model and extending ModelBuilder to do time building, that also will support simulation.
ArcGIS Server projects are being grown with scalability and quality. The new news here is the Personal server, which supports peer to peer, globe server, and distributed catalogs.
The vision is a scalable family of servers, that will enhance ArcIMS in the next release. "The personal server means that on my desktop I can connect to the internet and serve what I have," explained Dangermond. "I can let others access my metadata catalog, maps, download data and models, and it will support the notion of peer to peer GIS."
ESRI will also support distributed data management which will be replicated geodatabases, periodically updated, administration tools, history archiving, and will support an application at 9.1 (the stuff is there to build on your own in 9.0).
Catalogs will be accessed with a new web application for searching and using GIS resources. ArcGIS servers will support this. A new web application called Catalog Explorer will allow you to search catalogs and find what you need.
GIS Smart Clients are designed to extend GIS services to browser and mobile clients, allowing many emerging devices to flow information back and forth.
Tapestry is demographic segmentation life style segments. National Geographic used Tapestry to run an overlay of their subscribers to see what their readership is.
You can buy ArcWeb Services and host your own data with them. ESRI also has ArcWeb Location Services. Many solution partners are using this already.
Training and Support
ESRI now has curriculum packages, where you can earn a certificate of completion, and has one-half million virtual training students.
Twice a month they have a free one hour session called live training seminars, also downloadable after training occurs.
In the area of technical support, ESRI has added to the knowledge of their staff, and improved workflow for faster incident response, also improved call tracking.
There is big improvement in the Online Support Center.
The afternoon keynote speaker, Dr. Rita Colwell, has spent a lifetime focused on global infectious diseases, water and health. She is chairman of the Canon U.S. Life Sciences, Inc. and a distinguished professor at the University of Maryland at College Park and Johns Hopkins University Bloomberg School of Public Health. Currently, she is developing an international network to address emerging infectious diseases and water issues including safe drinking water for both the developed and developing world.
Historically, Dr. Colwell noted that cholera first appeared in 1854 in London. An enterprising Dr. Snow noticed a pattern of occurrence of the disease by putting dots on a map. The incidents centered around a well. Once they isolated this well the incidents abated. This was the first known example of how spatial handling leads to discovery. Colwell displayed Snow's map displayed in a GIS format. What would it have been like if Snow had been able to use ArcGIS? The use of advanced spatial data also places the center of the outbreak adjacent to the water source.
Cholera occurs worldwide and is a major health problem. It has been significantly prevalent in countries like Peru and Bangladesh, and also in the U.S. but not so prevalent.
Most of Dr. Colwell's research has taken place in Bangladesh. She zoomed in on an image, and said, notice the Himalayas and the amount of surface water in the delta region. "Much of Bangladesh is flooded, Daka has been flooded this year, the worst flooding since 1998 and there are 700 victims per day," said Dr. Colwell. She has collected cholera data from the last 40 years in that one city. There are extensive rivers and ponds in the region. "You can see how close the ponds are to where the houses are located. Houses are built right on the edge of the ponds, and many people are taking their drinking water from these ponds. They collect water in steel pots early in the morning, and families drink the water from those containers during the day."
