Geographical Information Systems
Ecological potential assessment of soil in agricultural lands in Hamedan Province, Iran, using geographic information system
The main purpose of the present study was to assess the ecological potential of agricultural soils using geographic information system (GIS). This research was conducted during 2014 in Hamedan Province, Iran. A cross-sectional study was conducted mapping the 10 factors of soil characteristics (texture, depth, erosion, and aggregation, percentage of slope, direction of slope, height, soil salinity, pH, and fertility) that affect ecological potential.
Noise pollution and its spatial distribution in urban environments (case study: Yazd city, Iran)
This study focuses on identifying source and frequency of noise pollution in Yazd, Iran. For data collection, we used two approaches: First we selected 55 monitoring stations for 122 km grid network; the distance between two stations was 2 km. Then, at the same time, we measured the sound pressure level (SPL) at main roads; the distance between two monitoring stations in this case was 1 km.
