This contribution deals with the benefits of the global positioning system, with the influence of the human factor on fuel consumption and with monitoring of further savings in operation of earthmoving machines in a construction company. Fuel consumption data of a selected earthmoving machine before and after installation of a global positioning system unit and a fuel level measurement sensor are compared. These data are evaluated and the extent of the influence of the installed devices on the machine fuel consumption is determined from them. Further possibility of exploitation of monitoring of earthmoving machines during excavation and creation of given relief is also described here. Not only the fuel savings were evaluated, but also the accuracy and speed of performed work and thus also the influence of the human factor on performance of earthmoving machines itself.

Geologic data from field observations and satellite imagery analysis contribute a constraint on the “pivot line” between uplift and subsidence of coral reefs, indicating the downdip rupture extent. Geodetic global positioning system (GPS) data contribute vector displacements of points on islands along the archipelago, indicating amount and direction of slip alongstrike of the rupture. Geodetic and geologic data are sensitive not only to rapid coseismic fault movement, but also to slower motion across the plate interface that occurs postseismically. Consequently, the source dimensions and slip pattern estimates based on various geodetic and geologic data differ from purely seismic estimates. A more complete understanding is emerging, based upon joint inversions that use various combinations of all available data, of ways in which sudden slip and gradual afterslip occurred in each of these two major plate boundary ruptures.

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.
