Creation of a Modernized Land Information System for Milwaukee County
This paper provides a case study of the creation of a parcel based land information system for a large metropolitan county. The paper describes the structure of the system and the technical...

3-D Coordinates - A Universal Rectangular Coordinate System for a GIS and Other Spatial Databases
Rules of solid geometry and 3-dimensional (3-D) rectangular coordinate systems are well known and used in many applications. Points on or near the earth's surface have long been described...

Quality of Map Data in Geographic Information Systems
Local government engineers wanting to take advantage of computer aided design (CAD) and geographic information system (GIS) need to understand the quality and accuracy of digital base...

Estimating Network Model Parameters from Mail Survey Data
Network models are generally based on a four-step modeling process; trip generation, trip distribution, modal split, and trip assignment. Microcomputer implementations of these steps have...

Better Ways to Update Trip Matrices
Updating origin-destination (OD) trip matrices usually involves considerable survey costs, so engineers are often forced to use dated OD information, which can seriously undermine the...
