As mapping products become increasingly digital and require rapid updating, it is necessary for survey companies to use fast and cost-effective technologies. Airborne laser mapping provides a new alternative for traditional photogrammetric mapping. Based on a scanning laser and GPS/Inertial positioning system, an airborne laser system automatically produces accurate digital elevation models (DE...

The proliferation of 'commercial off the shelf' geographical information systems into the scientific community has resulted in the widespread use of spatial climate data in a variety of applications. This paper presents a review of the role of geographical information systems in climatology and meteorology by i) discussing methods used to derive and refine spatial climate data and ii) reviewing...

Globally, rapid urbanisation is one of the major drivers for land-use changes, many which have a marked impact on urban air quality. Urban forestry has been increasingly proposed as means reducing airborne pollutants; however, limited studies comparatively assessed types, including forestry, their relationship with pollution city scale. We, thus, investigated spatial relationships between three...

urban landscape structural analysis; focused on the remnant patch mosaic network as the component with closest interdependency with air and water related processes was undertaken to find and propose environmental planning suggestions.assessments demonstrate that remnant patch mosaic network structure of tehran is still restorable. with appropriate corrective measures based on the natural lay ou...

Both airborne and terrestrial laser scanners are used to capture large point clouds of the objects under study. Although for some applications, direct measurements in the point clouds may already suffice, most applications require an automatic processing of the point clouds to extract information on the shape of the recorded objects. This processing often involves the recognition of specific ge...

ods, and Maryland has a variety of laws and regulations pertaining to forest practices (Hawks et al. 1993). Martus et al. (1995) reported on the proliferation of local regulation ofprivate forestry, which has increased more than fourfold in the past 10 years. They predicted that local regulation will continue to expand as people unaccustomed to traditionally rural activities, such as harvesting...

Background: Urban forestry is an emerging profession, yet its professional identity not clearly defined, nor does it have the full complement of support mechanisms commonly expected or needed by professionals. As a result, urban forest professionals rely on closely allied professions (e.g., arboriculture, forestry) resulting in frustration amongst and confusion lack awareness general public. Me...
