ASPRS WS #9. Assessing the Accuracy of GIS Information<br />
Created from Remotely Sensed Data: Principles and Practices<br />
CANCELLED<br />
ASPRS WS #10. GIS Management<br />
Room: Virginia B<br />
8:30 am - 5:30 pm<br />
PDH Hours: 8<br />
CEUs: .8<br />
Rebecca Somers, President, Somers-St. Claire<br />
This workshop provides strategies and techniques for successfully managing a<br />
GIS, and examines the major organizational and management issues involved in<br />
GIS development and operation. Learn how to manage a multi-participant GIS,<br />
implement GIS in complex organizations, expand GIS operations, integrate GIS<br />
into the organization’s information technology and operational environment, develop<br />
a GIS staff, perform GIS cost/benefit analysis, fund GIS operations, and manage<br />
geographic data sharing. The workshop is structured to include in-depth discussion<br />
of topics and issues of particular interest to the participants. A workbook<br />
containing presentation notes and references accompanies the workshop.<br />

ASPRS WS #11. Geodesy, Photogrammetric Mapping,<br />
and the Global Spatial Data Model (GSDM)<br />
Room: Virginia C<br />
8:30 am - 5:30 pm<br />
PDH Hours: 8<br />

Earl F. Burkholder, PS, PE , Department of Surveying Engineering,<br />
New Mexico State University<br />
This workshop will build on concepts of geodesy as related to geometry of the<br />
ellipsoid, level surfaces, and datums to show how spatial data for a GIS can be referenced<br />
in a common 3-D spatial data model whether the data are collected with<br />
GPS, by traditional total station surveying, or by photogrammetric mapping operations.<br />
Attributes of the Global Spatial Data Model (GSDM) will be described and<br />
spatial data accuracy as defined by the GSDM will be discussed. The session will<br />
close with questions about possible standardizations of procedures between disciplines<br />
for collecting, manipulating, storing, and using spatial information and for<br />
assessing the accuracy of 3-D data.<br />

ASPRS WS #12. A Handle on the Accuracy of Imagery-based<br />
Digital Elevation Data in Softcopy Environment<br />
Room: Wilson A<br />
8:30 am - 5:30 pm<br />
PDH Hours: 8<br />
CEUs: .8<br />
Dr. Raad A. Saleh, S&J International<br />
Automation has become a driving force in end-to-end softcopy production of digital<br />
elevation models and other surface data. The primary data are digital or film-based<br />
imagery. In film-based methods, accuracy specification of elevation data has been<br />
well understood, such as through the C-Factor of the production system. This<br />
workshop addresses accuracy specifications of surface data produced in the endto-end<br />
softcopy photogrammetric environment. Such an environment requires that<br />
new factors be accounted for, such as scanning resolution, automated collection<br />
techniques, and image acquisition systems. The workshop will include substantial<br />
discussion on the accuracy of other technologies for surface data, such as Lidar.<br />
