Open Topology Maps - The download from Hell?
The OpenTopography Portal is a GEON Project initiative to build an online system that provides integrated access to high-resolution topographic data, web-based processing tools, and enables the user community to share knowledge, experiences and resources. The OpenTopography Portal incorporates the GEON LiDAR Workflow (GLW) system for LiDAR point cloud access and processing and adds mechanisms for access to other data types. The goal of OpenTopography is to provide a portal where access to various public domain airborne and terrestrial LiDAR, bathymetry, and other topographic data can be centralized. We are currently seeking collaborations and partnerships that enable us to make more of these valuable data sets available online. If you have data you’d like to share, resources such as tools or documents to contribute, or are interested in collaborating, please contact us.
The OpenTopography Portal is a collaboration between computer scientists at San Diego Supercomputer Center and earth scientists atArizona State University (see the People page for information on the OpenTopography team).
Motivations
Over the past decade, there has been dramatic growth in the acquisition of publicly funded high-resolution topographic and bathymetric data for scientific, environmental, engineering and planning purposes. Because of the richness of these data sets, they are often extremely valuable beyond the initial application that drove their acquisition and thus are of interest to a large and varied user community. However, because of the massive volumes of data produced by high-resolution mapping technologies such as LiDAR, it is often difficult to manage and distribute these datasets via the Internet. Furthermore, the datasets can be technically challenging to work with, requiring specific software and computing resources that are not readily available to many users. Our goal is to use the OpenTopography Portal as a way to democratize access to high resolution topographic data and to allow users to share resources and knowled
