e analytic techniques (for example, creating the intersection of two regions, or creating a buffer zone around a region) and graphic display techniques (for example, color, pattern and symbolization) to generate reports.

A process is certified when it carries the public trust. To carry the public trust a process must be able to pass an audit--an audit by a blue-ribbon panel that verifies engineers can document what they did, under what guidelines, that the process used can be repeated by others and that the process was appropriate.

At first it may seem difficult or impossible to certify GIS processes using these definitions. But that assumption overlooks the huge investment already made in process guidance. There is a vast legacy of guidance, some of it extremely specific, relating to managing military and federal facilities. Such guidance takes the form of building codes, environmental legislation and regulation, policies related to handling nuclear and hazardous materials, and dozens of other sources. This guidance comes from federal, state and local governments; professional organizations; and military and federal regulations, technical bulletins and policy manuals.

6. DIGITALLY REQUESTING A PROCESS

The process for generating trusted reports is close to being defined. In the near future, we can expect to see algorithmically expressed processes nominated for approval to the institutions empowered with regulation and enforcement. The algorithms can be expected to "guide" and 'force" GIS report generators to locate, address and comply with regulations and policies relevant to any report they generate. And these processes will be interoperable across all public facilities, because they will be expressed in terms of a common spatial data schema and access common compliance bulletin boards .

The technology for digitally representing complex processes is simple. The GIS "process" is embedded in a hierarchy or network of templates. Each template represents a step or a milestone in an extremely detailed work breakdown structure of the over all process. At the lowest level each template is composed of views into the information appropriate for the step at hand, together with ready-to-use procedure calls or ''macros'' designed to process information into the form needed for the subsequent steps. High-level templates are built from low-level templates and serve to guide the user inexorably toward completing the process. At the highest level is a single template, embodying all the others, which represents the whole process. The top template might present itself to the user as a button on the desktop labeled with the name of (or an icon for) the process it represents.

The importance of these digital representation tools is that they allow us to define the process we want to use. As a result, multiple participants in the process use the same methodology consistently, and process results can be audited if challenged.

7. CERTIFIED GIS: STAMPED FOR APPROVAL

Soon, standard processes will be interoperable across management authorities of cities, counties and states, as well as military and federal facilities. By certifying GIS information and processes, and employing technology to digitally represent standard procedures, decision makers can be confident that GIS reports are trustworthy. And the public knows a certified GIS report that has been approved by a decision maker is trustworthy as well.

8. VALUABLE REGULATIONS

GIS certification is being driven by one of the most urgent and complex movements in the U.S. government: the good stewardship of public facilities and renewable and non-renewable natural resources. The following regulations are intended to enforce good stewardship at public facilities.
