The Water–Energy–Food Nexus Discovery Map: Linking Geographic Information Systems, Academic Collaboration, and Large-Scale Data Visualization

Determining the structure and map of vegetation of Mirabad protected area (Iran) using DEM and Geographic Information Systems (GIS)

The Mirabad protected area (S. Azarbaijan, Iran) has a variety of ecological nurseries due to elevation of the sea, physiographic factors, micro-climates and soil types, and has high vegetation diversity. Mirabad protected area in the Piranshahr-Sardasht axis is between the latitudes of 36° 23' and 36° 31' north, and the lengths 45° 15' and 45° 25', with an area of ​​11435 ha, in the elevation ...

Algorithms and Data Structures for Large Scale Geographic Information Systems: A Performance Analysis

In this work, the performance of a system for the efficient processing of topological queries on geographic vector data, relying on in-memory algorithms and data structures, is analysed and compared with existing and available systems. The proposed system focuses mainly on querying time. Experimental results are reported and discussed in order to evaluate its performance.
