nowadays urban sanitary landfill compatible with environmental principles and in line with sustainable development is a necessity. in this paper for the purpose of determining appropriate sanitary landfill sites in kohgilooye & boyerahmad province, , many data layers were used including: slope, land cover, distance to main roads, distance to cities & villages, geology, surface water network, di...

Remote sensing has been used mostly to produce analyses on different aspects and phenomena concerning territory. The approach is not different from the one employed when analysing maps in the sense that analysis depends on the nature of data, maps and satellite images being two different sources of spatial data. Obviously, analysis based on cartographic data is different from the one based on s...

This analysis identifies optimal areas for backcountry skiing in Maine using the following six parameters: elevation, distance to roads, average annual snowfall, aspect, slope, and population density. The most suitable areas correlated well with locations that were ski areas in the past, were once considered for ski area development, or are currently used for ski touring. Introduction The recre...

Efficient fastest path computation in the presence of varying speed conditions on a large scale road network is an essential problem in modern navigation systems. Factors affecting road speed, such as weather, time of day, and vehicle type, need to be considered in order to select fast routes that match current driving conditions. Most existing systems compute fastest paths based on road Euclid...

To optimize ecosystem services provided by agricultural drainage networks (ditches) in headwater catchments, we need to manage the spatial distribution of plant species living in these networks. Geomorphological variables have been shown to be important predictors of plant distribution in other ecosystems because they control the water regime, the sediment deposition rates and the sun exposure ...

Traffic load and transported quantity due to forest management were analysed on the forest roads in the forest district Dragatu{, SE Slovenia. On the basis of timber gravitating to particular sections, the traffic load and transported quantity were calculated for each of seven forest road sections. The cumulative traffic load is the highest on the section connected to the public road and the lo...

transportation as a prerequisite and basics of stable development has a key role and great efficiency in seeding facilities and intellect. it has also a significant role as an effective index in growth and development to the extent that the number of accidents in our country are increasing which carries with them a lot of financial, psychological and social losses, for this reason, it seems to ...

We have developed a lane change aid system (LCAS), which detects vehicles behind in adjacent lanes with multi-line CCD sensors and informs the driver of vehicle location with a head-up display (HUD). Instead of processing camera images directly, a multi-line CCD sensor contains the pairs of line CCDs and measures two-dimensional distance distribution by comparing the brightness on line CCDs. To...

The average travelling speed increases in a nontrivial manner with the travel distance. This leads to scaling-like relations on quite extended spatial scales, for all mobility modes taken together and also for a given mobility mode in part. We offer a wide range of experimental results, investigating and quantifying this universal effect and its measurable causes. The increasing travelling spee...
