Improving user assessment of error implications in digital elevation models
A digital representation of a terrain surface is an approximation of reality and is inherently prone to some degree of error and uncertainty. Research in uncertainty analysis has produced a vast range of methods for investigating error and its propagation. However, the complex and varied methods proposed by researchers and academics create ambiguity for the dataset user. In this study, existing...
متن کاملError Measurement in Multiresolution Digital Elevation Models
Multiresolution models are getting more and more importance for a scale-sensitive modelling of spatial data. In principle, they allow the representation of the data at a variety of scales. Of special importance are adaptive methods, where the resolution does not need to be uniform but may be variable. Then, error indicators are used to control the local resolution of the model. In this paper, w...
متن کاملQuality assessment digital elevation models
A number of published stereo matching algorithms have been implemented and tested on SPOT images of areas for which we have gridded digital elevation models (DEMs) available with spacings of 80m or less as well as ground control checkpoints. Results will be presented for a comparison of stereo matched output with the DEMs and an analysis of the errors arising and their causes. Results will be d...
متن کاملThe Importance of Understanding Error in Lidar Digital Elevation Models
The paper presents the results of an accuracy analysis of a number of gridded Digital Surface Models (DSMs) which have been created from first return laser scanning (LiDAR) data. DSMs are created using a variety of methods, and differences between the models and the raw LiDAR data are quantified and the spatial patterns of the errors explored. The results presented in this paper demonstrate the...
متن کاملOn the improving of elevation accuracy of Digital Elevation Models: a comparison of some error detection procedures
The widespread availability of powerful desktop computers, easy-to-use software tools and geographic datasets have raised the quality problem of input data to be a crucial one. Even though accuracy has been a concern in every serious application, there are no general tools for its improvement. Some particular ones exist however, and we are reporting here results for a particular case of quantit...
