Multi-Scale GIS : From Generalisation to Data Integration
نویسنده
چکیده
The paper analyses the requirements on automated generalisation when applied in the context of an existing multiple-resolution data infrastructure, where the small scale data sets should not be replaced but kept and updated incrementally. The situation is explained by example of the official German topographic-cartographic information system ATKIS.

Database Architecture for Multi-scale Gis
Many applications of GIS, such as planning, exploration and monitoring of natural resources, require the mapping and analysis of spatial data at widely differing scales. Ideally, a single large scale representation of spatial data might be stored, from which smaller scale versions were derived. Currently however, automation of the necessary generalisation processes is not sufficiently well adva...
متن کاملMulti Objective Scheduling of Utility-scale Energy Storages and Demand Response Programs Portfolio for Grid Integration of Wind Power
Increasing the penetration of variable wind generation in power systems has created some new challenges in the power system operation. In such a situation, the inclusion of flexible resources which have the potential of facilitating wind power integration is necessary. Demand response (DR) programs and emerging utility-scale energy storages (ESs) are known as two powerful flexible tools that ca...
متن کاملSite Selection for Rainwater Harvesting for Wildlife using Multi-Criteria Evaluation (MCE) Technique and GIS in the Kavir National Park, Iran
This research is an integration of GIS and multi-criteria decision making into a joint framework for identifying suitable areas for rainwater harvesting structures. The Kavir National park in Iran has been evaluated for suitability of rainwater harvesting. To this end, slope gradient, distance to guarding stations, distance to watering points for transporting collected water, distribution of wi...
متن کاملMulti-Scale Spatial Database and Map Generalisation
The constitution of multi-scale spatial databases is closely linked to map generalisation. Elements of a multi-scale spatial database include multi-scale data models, multi-scale data storage schemes, methods to generate multi-scale datasets and methods to access these datasets and present results. In this paper we proposed a formal multi-scale spatial data model with an information-rich struct...
متن کاملA Data Model for Multi-scale Topographical Data
The lack of fully automated generalisation forces National Mapping Agencies to maintain topographical data sets at different map scales. For consistency between map scales, but also for supporting (future) automated generalisation processes, information on similarities and differences of the separate data sets should be identified and formalised. This includes information on valid data content ...
