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.

AbstractPrecision, reliability and cost are the major criteria applied in optimization and design of geodetic networks. The terrestrial networks are being replaced quickly by permanent and campaign Global Positioning System (GPS) networks. These networks must be optimized using the same three criteria. In this article the optimization of the observational plan of local GPS networks (Second Order Design (SOD)) is considered using the precision criterion. This study is limited to the selection of optimal numbers and the best distribution of the non-trivial baselines throughout the network. This objective is accomplished based on the SOD solution through the analytical method in operational research by the means of quadratic programming algorithm. This presented method is tested on a real GPS network and appears to be a useful technique in terms of cost reduction in the field work by the provided observational plan and optimal distribution of the baselines throughout the network. Results indicate that weights of almost 36% of the baselines are negligiblewhen compared to the weights of the rest of the baselines; therefore, they could be eliminated fromthe observational plan, resulting in a 36% saving in the fieldwork cost.

Soft Copy

This article describes and evaluates the application of a soft-copy photogrammetry system to large-scale forest inventories. A specially designed software, developed by the authors, has been investigated in terms of accuracy and general operability. Tests based on 1:1100 color aerial photographs, taken with a 10-m cross-boom system and digitized at resolutions of 300, 450, and 600 dots per inch, confirmed the expected tree-height accuracies of 48, 32, and 24 cm, respectively. This indicates that a photographic scale of 1:800 and a scanning resolution of 800 dots per inch could produce a tree-height precision of the order of 10 cm. The tests have shown that model orientation takes about 15 min; for a tree plot of 24 trees, measurements (height and crown diameter) and observations (species and condition) also take about 15 min. As the important problem of positioning a helicopter over a tree plot has now been solved using global positioning system receivers, the results and information presented in this paper indicate that the existing technology can provide a rigorous and operational photogrammetric system for large-scale forest inventories and regeneration monitoring.

Public Areas

The main objective of our project is to provide security for human beings especially woman and children with a help of an advanced electronics. As most of the women are subjected to unethical physical harassment when they are alone in public areas, in case they will be provided with an equipment fitted inside the shoes which is not visible to others, the equipment consists of GPS (Global Positioning System) and GSM module by which the geographical location can be tracked and can be sent. In the case of any emergency conditions, the button is pressed and the microcontroller sends latitude and longitude information to authorized persons through GSM. Then the location information is tracked and the information can be sent to police and family members so that they can be rescued in proper time. At the same time, they will be provided a high voltage generating device embedded within the system can be used to generate electric shock to temporarily paralyse the criminals in critical situations. The device is portable and hence can be taken anywhere we travel. It is economical and simple to use. So, it can be effective in saving many people (not merely women) from criminal attacks, sexual harassments and can be used as legal evidence of crime.

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.
