High-precision land-cover-land-use GIS mapping was performed in four major townships in Maine’s Aroostook River Valley, using on-screen digitization and direct interpretation of very high spatial resolution satellite multispectral imagery (15–60 cm) and high spatial resolution LiDAR data (2 m) and the field mapping method. The project not only provides the first-ever high-precision land-use maps for northern Maine, but it also yields accurate hectarage estimates of different land-use types, in particular grassland, defined as fallow land, pasture, and hay field.

Rosetta Promontory, Egypt has been suffering from a continuous erosion problem. The dramatic retreatment was observed during the last century. It is basically due to the construction of Aswan High Dam in 1964, which reduced the flow and sediment discharges. In this paper, four Landsat images (two Thematic Mapper and two Enhanced Thematic Mapper) covering the period from 1984 to 2014 were used.

By 2050, 90% of the population in Latin America will live in cities, but there is a lack of up-to-date spatial information about the urban extent and patterns of urbanization in cities of this region. In this study, we analyzed population growth, urban density and urbanization dynamics between 1992 and 2009 in the major cities of Bolivia, Colombia, Ecuador and Perú using Google Earth and DMSP/OLS night-time lights imagery. We used Google Earth to map the urban extent, and time series of night-time lights to analyze spatial patterns of urban development.

Pollination is a key ecosystem service as many crops but in particular, fruits and vegetables are partially dependent on pollinating insects to produce food for human consumption. Here we assessed how pollination services are delivered at the European scale. We used this assessment to estimate the relative contribution of wild pollinators to crop production. We developed an index of relative pollination potential, which is defined as the relative potential or relative capacity of ecosystems to support crop pollination.

Vegetation and land-cover changes are not always directional but follow complex trajectories over space and time, driven by changing anthropogenic and abiotic conditions. We present a multi-observational approach to land-change analysis that addresses the complex geographic and temporal variability of vegetation changes related to climate and land use.

A Land Information Management System (LIMS) is an information system that enables the capture, management, and analysis of geographically referenced land-related data in order to produce land information for decision-making in land administration and management. The system is a Geospatial Information System (GIS) driven for the purposes of handling and managing parcel based information. The Republic of Kenya, located in East Africa, ranks 33rd in the world in terms of population with 38.6 million people and has a land area of 224,081 square miles.

This paper describes the development of a Land Information Management System (LIMS) for County Governments in Kenya. In the new Constitution 2010, devolution of some national government functions and formation of county governments was provided for. These invoked the development of new land laws to guide the devolution processes and procedures. According to the County Government Act 2012, all County Governments are supposed to develop digital Geographic Information System (GIS) based spatial plans and these calls for development of LIMS for and efficient breakthrough.

Gediz Delta is place of empties itself into the sea of Gediz River. Its one of the important wetland of Turkey which under the protection of Ramsar Convention. It has lots of lagoones, salt marshes, freshwater marshes, large saltpans and also ornitotourism place Kuş Cenneti. Gediz Delta has rich flora and fauna biodiversity because of this its important place for natural life sustainability.

Today, natural and cultural reserves are being rapidly lost; however, no efficient protection approaches are being put forward. Existent reserves face with the danger of extinction as the result of the land-misuses and excessive utilisation. In order to make accurate and effective reserve management and planning decisions, optimal land-uses targeting the preservation ecological structure should be determined elaborately.
