This paper presents the concepts and technology of GMN and its application in developing real estate management software. GMN abbreviating GIS+MIS+Network, is a new technology integrating Geographic Information Systems (GIS) and Management Information Systems (MIS) in the Internet environment. Previous real estate management software products which are mainly based on MIS cannot meet various es...

The inclusion of error handling capabilities within geographical information systems (GIS) is seen by many as crucial to the future commercial and legal stability of the technology. This thesis describes the analysis, design, implementation and use of a GIS able to handle both geographical information (GI) and the error associated with that GI. The first stage of this process is the development...

Due to the great possibility of water contamination of many rivers by human activities in Iran, the study of water quality is crucial for water resource protection and human health. High level of phosphorous is the main reason for eutrophication of freshwater systems. The main aim of this study was to investigate the concentration of phosphorus in the rivers feeding into Taham dam in Zanjan, us...

Software Architecture design is to be a key step in the process of software development. For large and complex emergency network geographical information system in practice, it is ridiculous to achieve the goal of emergency management based on unsuitable software architecture. At present, the network geographical information system software architecture can be divided into four layers: display ...

Abstract Background The main obstacle for local and daily or weekly time-series mapping using very high-resolution satellite imagery is the high price availability of data. These constraints are currently obtaining solutions in line with development improved UAV drone technology a wider range imaging sensors that can be used. Findings Research conducted Inspire 2 quadcopter drones RGB cameras, ...

This paper presents an endeavour of integration of GIS (Geographical Information System) and BIM (Building Information Modelling) for indoor geovisual analytics. The merits of two types of technologies, GIS and BIM are firstly analysed in the context of indoor environment. GIS has well-developed capabilities of spatial analysis such as network analysis, while BIM has the advantages for indoor 3...

he expanding presence of geographic information system (GIS) offices within organizations has helped to enhance the availability of GIS data and expertise, but not always to the benefit of the entire organization within which it is working. The separation— and frequently, isolation—of GIS specialists within agencies, institutions, and organizations often limits the potential usefulness of GIS t...

Currently there are software packages that allow a user to analyze GIS data. The problem is that the software is limited in the interaction provided. This paper presents a method for merging digital elevation models (DEM) and GIS vector layers, and also provided is an interactive visualization tool for analyzing the output.
