With the increase in permanent forest clearing, global deforestation is having a major impact on our finite resources. A growing public awareness of current forestry practices around the world is provoking people to question the management of these valuable forested regions. We will present a conceptual model that links visualizations and quantitative data to spatial locations over a range of t...

Geocoding is increasingly being used for public health surveillance and spatial epidemiology studies. Public health departments in the United States of America (USA) often use this approach to investigate disease outbreaks and clusters or assign health records to appropriate geographic units. We evaluated two commonly used geocoding software packages, ArcGIS and MapMarker, for automated geocodi...

ArcGIS ist ein vollständiges, durchgängiges System zu Erstellung und Verwaltung von Karten und geografischen Informationen. Es bietet vielfältige Methoden zur Visualisierung und räumlichen Analyse von Geodaten mit dem Ziel, Informationen mit Raumbezug – immerhin schätzungsweise 80 Prozent aller Daten weltweit – verständlicher darzustellen und damit Entscheidungen besser und effizienter treffen ...

In Canada, flooding is the most common and costly natural hazard. Flooding events significantly impact communities, damage infrastructures threaten public security. Communication, as part of a flood risk management strategy, an essential means countering these threats. It therefore important to develop new innovative tools communicate with citizens. From this perspective, use story maps can be ...

Currently, there is no spatial DBMS that implements a rule-based topology engine (considering that the topology rules are designed and performed in the spatial backend). If the topology rules are applied in the frontend (as in many GIS desktop programs), ArcGIS is the most advanced solution. The system presented in this paper has several major advantages over the ArcGIS approach: it can be exte...

It is an important to offer a user friendly interface in WebGIS. Excellent map services can be offered by ArcGIS Server. But the problem that the client fetches some data on a Web page from the server quickly is not solved well by ArcGIS Server, Ajax technology can overcome it. When getting large amount of data from server, It takes long time to parse the data for Ajax. To the study “Beijing Ag...
