Modern forest management presents ever increasing demands for accurate and up-to-date forest inventory information. The process of inventory update is critical. Inventory update in Canada is examined including update for harvest, burns, insect and disease, silviculture, roads and other changes. The magnitude and requirements of the update task are documented. The procedures used are described and summarized by province in table form. Usage, advantages and disadvantages of current methods (e.g. conventional 9 × 9 aerial photography, supplemental aerial photography, satellite imagery, and aerial reconnaissance) are examined, new methods discussed and trends highlighted. Also outlined are issues related to the incorporation of silviculture and insect and disease information into inventories and the structure and responsibilities for update. Key words: forest inventory, inventory update, harvest, burns, insect and disease, blowdown, silviculture, aerial photography, satellite imagery, Global Positioning System, aerial reconnaissance, video

Simulation Results

GPS (Global Positioning System) is the popular system for navigation which assistance 32 satellites orbiting the earth. Currently, tracking positions using the Global Positioning System (GPS) is one of the best positioning tracking methods. However, GPS has a lot o f noise, so filters are needed to handle with noise on GPS. In this research, the simulation is done to extract data from GPS sensors using RLS algorithm. From the results o f identification and simulation, it can be concluded that the algorithm works well and need to analyze the advantages and disadvantages to be implemented on the downlink system designed. From the simulation results obtained that error estimation is convergent that is the longer the smaller.

Theadvancement of smartphones, global positioning system, and information technologies have a great influence on our travelling preferences and behaviour, dynamically shaping the transportation industry. In addition to providing convenience to the riders, it also has created some debate among the stakeholders, including the policy makers. This paper presents a quantitative study of Taxi service experience in Jordan. The aim of the study is to evaluate Jordanians’ experiences with yellow taxi services, assess their opinion toward advantages and disadvantages of Uber taxi services in Jordan and obtain opinions on the expected future of Uber taxi services.

Hydrocarbon Reserves

The exploitation of offshore hydrocarbon reserves needs consistent high accuracy positioning in many applications throughout all operational stages from exploration to development and subsequent field maintenance.Traditionally, this requirement has been met by a variety of terrestrial electronic position-fixing aids all of which have advantages and disadvantages in relation to different offshore tasks. Now satellite systems are being developed which will have a major impact on offshore positioning and the most important of these is the American NavStar Global Positioning System (GPS).In GPS the marine navigator and surveyor at last has a system that potentially can give him a truly global 24-hour real-time high-accuracy system which will meet or assist with many of his requirements for positioning.However, great care must be exercised in the use of this military system over which the civil user has no direct control. In addition, errors in the system, some inherent and some deliberately applied, must be monitored and if possible corrected. Consequently, significant civil user infrastructure must surround the application of GPS for offshore work in order to achieve the high-quality accurate service demanded.This paper discusses the current and future performance of GPS and looks at the sources of error, with particular attention to the deliberately applied Selective Availability, arguing the need for a robust, monitored, differential environment, but noting the problems of providing a dependable data link.

O posicionamento e a instalação de unidades amostrais em trabalhos de Inventário Florestal exigem critérios (métodos e processos), que podem ser facilitados com o uso de recursos tecnológicos, saindo de uma esfera teórica para a prática. Neste sentido, o presente trabalho tem como finalidade apresentar um exemplo concreto de aplicação do Sistema de Posicionamento Global (GPS) para fornecer a posição geográfica (latitude e longitude) e a altitude do terreno em relação ao nível médio dos mares de parcelas amostrais em um inventário florestal. O processo de amostragem para o Inventário Florestal foi à amostragem sistemática em dois estágios. Concluiu-se que a utilização do GPS, como ferramenta de localização, navegação e apoio ao inventário florestal, proporcionou melhor rendimento, bem como uma economia de tempo e recursos na execução da atividade. GPS: A Helpful Tool in Forest Inventory Abstract Positioning and establishing sample plots in forest inventories are tasks which require the definition of some criteria (methods and processes). This may be facilitated by using some technological devices that make the survey a very practical task. In this connection, this work aimed at presenting a clear example of application of Global Positioning System (GPS) used to give the geographical location (latitude and longitude) as well as the altitude of the land in relation to the medium level the seas of forest inventory sample plots. The sampling scheme used in the inventory was the double stage systematic process. It was noticed that GPS utilization, of location, sailing and as a tool to support forest inventory plot establishment, provides better efficiency in field work as well as improved time and resources use.

Seiring dengan pesatnya kemajuan teknologi saat ini, kebutuhan manusia menjadi lebih beragam, termasuk kebutuhan akan informasi. Tidak hanya media informasinya yang semakin beragam, jenis informasi yang dibutuhkan juga semakin beragam, salah satunya adalah kebutuhan informasi akan posisi kita terhadap lingkungan sekitar. Untuk memenuhi kebutuhan itu sebuah sistem pemosisi diciptakan. Sistem pemosisi yang banyak digunakan saat ini cenderung berfokus pada lingkup ruang yang besar (global) padahal, dalam lingkup ruang yang lebih kecil (lokal) sebuah sistem pemosisi juga diperlukan, seperti di ruang-ruang terbuka umum (taman atau kebun), ataupun dalam sebuah bangunan. Sistem pemosisi lokal yang ada saat ini sering kali membutuhkan infrastruktur yang mahal dalam pembangunannya. Aplikasi Pemosisi Lokal Berbasis Android dengan Menggunakan GPS ini adalah sebuah aplikasi yang dibangun untuk memenuhi kebutuhan pengguna akan informasi lokasi dan posisi mereka terhadap lingkungan di sekitarnya dalam lingkup ruang yang lebih kecil (lokal) dengan memanfaatkan perangkat GPS (Global Positioning System) yang telah tertanam dalam perangkat smartphone Android agar infrastruktur yang dibutuhkan lebih efisien. Dalam implementasinya, Aplikasi Pemosisi Lokal ini bertindak sebagai klien dengan dukungan sebuah Database Server yang berfungsi sebagai media penyimpanan data serta sumber referensi informasi yang dapat diakses melalui jaringan internet sehingga tercipta sebuah sistem yang terintegrasi secara global. Kata kunci: aplikasi, informasi, pemosisi, GPS.

This paper examines the distribution of hospitality services in Uyo Urban, Nigeria. GIS method was the primary tool used for data collection. A global positioning system (GPS) Garmin 60 model was used in tracking the location of 102 hospitality services in the study area. One hypothesis was stated and tested using the nearest neighbour analysis. The finding shows evidence of clustering of the various hospitality services. The tested hypothesis further indicated that hospitality services clustered in areas that guarantee a sustainable level of patronage to maximize profit. Thus, the hospitality services clustered in selected streets in the metropolis while limited numbers were found outside the city’s central area.
