The “Myth”


“Surveyors have missed the GIS boat”,

as stated during a presentation at a recent meeting of

national leaders of the surveying profession.

The Myth

Legislated Authority


Public Act 299 of 1980, Michigan Compiled Laws:

Section 339.2001 (F)(iii):The practice of professional surveying includes all of the following:

(iii) Utilizing and managing land information systems through establishment of datum and local

coordinate systems and points of reference.

Model Rules, as prepared by National Council of Examiners for Engineers and Surveyors, Section 210.25:

Activities Included within the Practice of Surveying … that must be accomplished by or under the

responsible charge of a professional surveyor include, but are not limited to, the following:

1. The creation of maps and georeferenced databases representing authoritative locations for

boundaries, the location of fixed works, or topography.

The Myth

Definitions:


Geographic Information System (GIS): “GIS has referred to spatial information whose detail,

accuracy, and precision generally correspond to maps at scales of 1:20,000 of smaller.”

Typical products are those designed to support policy making and planning processes.

Land Information System (LIS): “..the term land information system (LIS) conveys a stronger

orientation toward land records and a larger scale than the term GIS”. An LIS requires higher

positional accuracy and detail than a GIS.

Typical products are property appraiser’s maps, maps of subdivisions, utility maps, right

of way maps and all tabular records and files associated with the maps.

Source: FGCC, Multipurpose Land Information Systems, 1989

The Myth

Blending of GIS and LIS


“By 1992, the term GIS had more or less been adopted as a general heading for all

projects and systems that involved land management.”

Michael Binge, Surveying GIS: The need for a multipurpose cadaster

revisited.

In “GIS Guidelines for Assessors”, Urban and Regional Information Systems Association

(URISA) identifies the fundamentals of GIS as:

1. Geographic Control Data

2. Base Map Data

3. Cadastral Data

4. Attribute Data

The Reality


“A big challenge is integrating the surveying profession with the

GIS profession. There’s a growing tension between them.”

Jack Dangermond, ESRI Founder

As stated in Coordinates, March 2007

The Myth

Data Analysis Other

• Only 13.9% of surveyors consider data management to be their most important usage.

• Cost is the least significant reason for not using a GIS.

• The major reason is a lack of understanding of GIS capabilities.

• Surveyors DO use GIS!

• Only 13% use GIS “Never” or “Seldom”

• Google products are used by many, but should be used by all surveyors.

• County-based GIS systems provide online parcel-based research via ArcGIS, which may account for a significant amount of the ArcGIS usage.

Summary and Revised Premise

GEOG 596A Capstone Project Presentation 13

Surveying Profession and GIS

• Long association

• Reluctant to embrace

• Cost is a concern, but not the reason

• Lack of knowledge is the reason for the reluctance.

Revised Premise

• It is a lack of knowledge about the potential uses of GIS that is the root of the

reluctance by the surveying profession to embrace GIS.

“Before” Benchmark Data Mgmt


Search tool was a manual process:

Step 1: Grab a book/folder/file.

Step 2: Look for benchmark.

Step 3: Repeat till found

Results:

• Time consuming

• “First Found”

Universal Control Point Schema


Base Schema

The tool’s functionality will

require a standardized

table.

The table will be based on

the schema developed by

NGS.

Additional fields will have to

be added to adapt to local

control.



Outcomes

1. A research tool that will

1. Improve functionality

2. Enhance efficiency

3. Increase profitability

2. A tool and process that will demonstrate the vital use of

GIS for data management within an organization. No

longer will GIS just be a gateway software platform for

accessing county-based data.
