The Proposed LAS 1.4 Specification Crashes Software and Corrupts Data

The LAS format – introduced in 2004 by the ASPRS – has become the de-facto international standard for storing and exchanging point data acquired by airborne LIDAR scanners. It has wide acceptance and can be read and written by almost any LIDAR processing software. There now exist Exabytes of LIDAR that can easily be exchanged

Wide Area Engineering and the Future of GIS

GIS has its roots in what a geographer or cartographer might call “small-scale” information, information primarily related to issues of land management and the environment.  In the early days, there were many competing acronyms for what is now known as GIS, such as Land Information Systems (LIS), and Facility Information or Facility Management Systems (FMS).

Geolocation and Privacy: Are We Going the Right Way?

The concept of geolocation privacy is now receiving a good deal of attention in the United States. For example, nine bills are being considered on Capitol Hill that would would regulate the collection, use and/or transfer of geolocation information. Many of the bills include geolocation as part of larger privacy bills and treat an individual’s

Engaging New GIS Students with Web Mapping

Not that long ago, I considered “web mapping” an advanced topic, best left to be taught in a senior GIS course.  While that can still be the case, depending on how it is defined, the fact is that creating a map of your own data on a web page has become something anyone can do

BIM for Facilities Management and 3-D GIS

Building Information Modeling (BIM) is replacing Computer Aided Drafting (CAD) as the tool in which building designs are created. BIM is a graphic and data model of a building prepared by designers, enhanced by builders, and can be used by owners. BIM enables all parties involved in a project to communicate in a more collaborative

Gap Filling Strategies with Data Integration

The assignment of novel educational and research tasks brings the certainty that Europeans will be part of a new era of the utilization of “Culture”: an era with broader exploration ambitions in “research and education” for the CITHM (Culture, Innovation & Technologies for Heritage Management) in Mediterranean Regions. “The Risk of Education explores what is

How Do We Reach and Teach Casual GIS Users?

There are many people who don’t consider themselves geospatial professionals, but instead are casual GIS users. They probably don’t go to GIS conferences, or keep up with everything that’s happening in the field, and yet I’ll bet they perform a sizeable proportion of all of the mapping and spatial analysis tasks that are done on

Intelligent City Models and Transportation Infrastructure

A recent Perspectives column in V1 Magazine noted the potential for using intelligent 3D city models for airports. At Galdos, we believe this is definitely true, and not only for airports, but for many other types of transportation infrastructure including rail stations, and seaport facilities. Furthermore, suitable city models can be used to provide effective

A 3-D Model – Equal To A Thousand Data Attributes?

Recently, I was asked if I would teach a Google SketchUp course to a group of planners. I’d put together similar courses in the past, with the objective of giving a basic understanding of 3D concepts and workflows. Always on the ready to exploit any opportunity that spreads knowledge about the power of 3D, I

Planning 2.0—The Next Generation of Participatory Planning

Today, cities are growing beyond their physical limits and resource capacities. This sprawling growth encroaches on prime agricultural land and creates severe socioeconomic and environmental problems.
