Land use suitability assessment is an important fundamental work in urban-rural planning. Be restricted by technology and means, qualitative analysis methods be wider used in evaluating land use suitability in most districts of China. This method can’t impersonally and Quantitatively indicate the difference in land use suitability, and make urban-rural planning more subjectively because the inf...

This study proposed a risk assessment model integrating remote sensing (RS) and geographic information system (GIS) to map potential illegal waste dumping areas. Geospatial factors related to waste dumping were generated with spatial analysis to quantify the spatial relationship between waste dumping sites and other land use/cover types. The spectrally suspected waste dumping mapping with FORMO...

Landslide hazard assessment is an important step towards landslide hazard and risk management. There are several methods of Landslide Hazard Zonation (LHZ) viz. heuristic, semi quantitative, quantitative, probabilistic and multi-criteria decision making process. However, no one method is accepted universally for effective assessment of landslide hazards. In recent years, several attempts have b...

In order to improve the administrative level of pipeline safety among the surrounding environment, this paper proposes a pipeline risk assessment system of space and visualization based on the current situation of the gas pipeline risk assessment. The database of pipeline surrounding natural environment and social environment are established by using GIS. And the scatter grams on the accident s...

We present a novel GIS, Real Space GIS, which is a 2D & 3D integration GIS. Real Space GIS is based on Real Space which is 3D geographical space and 2D map space which is based on geographical sphere or ellipsoid comparing to Paper Space GIS which is based on traditional Paper Space based on paper map coordinates. Real Space GIS mainly integrates data structure, data model, data storage, data v...

The assessment of Small Hydro Power (SHP) sites for project planning and development represents a relatively high proportion of overall cost. A high level of experience and expertise is required to accurately conduct this multidimensional assessment at both pre-feasibility and feasibility analysis stage. A variety of multi-criteria decision analysis or making (MCDA or MCDM) methods as well as c...

BACKGROUND Assessment of the spatial accessibility of hospital accident and emergency departments as perceived by local residents has not previously been investigated. Perceived accessibility may affect where, when, and whether potential patients attend for treatment. Using data on 11,853 respondents to a population survey in Caerphilly county borough, Wales, UK, we present an analysis comparin...

A common method to assess land use/cover change (LUCC) is the comparison of digital maps of an area within a geographic information system (GIS). However, positional errors of the maps involved in the comparison affect this assessment and much of the change shown by means of this comparison may be an artifact due to these errors. This note presents a simple method to improve change estimates by...

Web-based geographic information system (GIS) technology, or web-based GIS, offers many opportunities for public planners and Extension educators who have limited GIS backgrounds or resources. However, investigation of its use in planning has been limited. The study described here examined the use of web-based GIS by public planning agencies. A 2013 web-based survey of 274 public planning agenc...
