2016/11/8
Producing maps and geo-data at different scales is traditionally one of the main tasks of National (and regional) Mapping Agencies (NMAs). The derivation of low-scale maps (i.e. with less detail) from...
GENERALISATION OF 3D BUILDING MODELS BY CELL DECOMPOSITION AND PRIMITIVE INSTANCING
Generalization Algorithms Building Three-dimensional GIS Visualization

The article presents a cartographic generalisation approach for 3D building models with regard to the thematic visualisation of urban
landscapes. Based on our earlier work to utilise approximating p...
GENERALISATION AND DATA QUALITY
Data Quality Quality Criteria Automatic Generalisation Validation Fitness for Purpose
2015/9/21
The quality of spatial data has a massive impact on its usability. It is therefore critical to both the producer of the data and its users. In this paper we discuss the close links between data qualit...
In this paper, a new approach is presented for the simplification or rather generalisation of building ground plans that are represented
as 2D line segments. It is based on half-space modelling and c...

2014/4/24
The drainage pattern of a river network is the arrangement in which a stream erodes the channels of its network of tributaries. It can
reflect the geographical characteristics of a river network to ...
