Spatial Pictogram Enhanced Conceptual Data Models and Their Translation to Logical Data Modelsach effectively reduces the cluttering, as spatial relationships will become implicit. We have provided a complete grammar using “yacc” like syntax to translate the pictogram-extended ER diagram into a SQL3-level logical data model using OGIS-standard spatial data types.

Change Detection by Classification of a Multi-temporal Imaged subdivision of the area could be defined by ancillary data in a geographic information system, but can also be obtained by multi-temporal image segmentation. A case study is presented where land-cover is monitored over an 11-years period in an area in Brazil with drastic deforestation.

Improving High-Dimensional Indexing with Heuristics for Content-Based Image Retrievalnode. Our approach has been implemented and tested on an image database. Our experiments show that the proposed approach can improve the quality of high-dimensional indices without much run-time overhead.

Comparison of the Potential of Different Sensors for an Automatic Approach for Change Detection in Ga system), the Indian satellite IRS-1C, the MOMS-2P camera and from a laser scanning system as an additional information source. The GIS data which have to be updated are from the German national topographic cartographic database (ATKIS) and were captured in the scale of 1 : 25,000.

Relational Algebra for Spatial Data Managementlt is defined uniquely. Most important, the operations represent adaptations of others that had been used in previous research for the modeling of temporal data. Hence, the model applies uniformly to the management of conventional, spatial and temporal data.

Cost-Effective Determination of Biomass from Aerial Images is used to identify individual tree species, and the laser profiler is used to estimate tree heights. The second procedure builds on this approach by taking sequences of 70mm photographs with an 80% overlap along a second higher altitude flight line at 4,000 feet. Detailed 3D terrain models are the
