The World

Globally, maps are our primary source of comprehensive information about the shape, size and arrangement of Earth features. Maps are the only way we can get a unique and comprehensive view of the world. Unfortunately, globally, all maps are somehow deformed, affecting our perception and understanding of the various geometrical properties of the world. Cartographic projection is a way of mapping points from an ellipsoid to a plane and as such is the basis for making a mathematical map basis. The two projections most used in our geospatial are the Gauss-Krüger projection and the UTM (Universal Transverse Mercator) projection. The paper deals with Helmert's transformation of these two projections.

The national coordinates system used in Nigeria is the Universal Transverse Mercator projection, while China adopts the Gauss Krugger Transverse Mercator projection (GKTM). This paper studied the difference between UTM and Gauss(TM) projections and the regulation of projection deformation, and put forward the model of the coordinates system for the Nigeria railway, which shall be of great benefit in the survey, design, construction and referencing of the Nigeria railway project.

Coordination Methods

The issue of calculating the plane rectangular coordinates using the data obtained by the satellite observations during the creation of the geodetic networks is discussed in the article. The peculiarity of these works is in conversion of the coordinates into the Mercator projection, while the plane coordinate system on the base of Gauss-Kruger projection is used in Russia. When using the technology of global navigation satellite system, this task is relevant for any point (area) of the Earth due to a fundamentally different approach in determining the coordinates. The fact is that satellite determinations are much more precise than the ground coordination methods (triangulation and others). In addition, the conversion to the zonal coordinate system is associated with errors; the value at present can prove to be completely critical. The expediency of using the Mercator projection in the topographic and geodetic works production at low latitudes is shown numerically on the basis of model calculations. To convert the coordinates from the geocentric system with the Mercator projection, a programming algorithm which is widely used in Russia was chosen. For its application under low-latitude conditions, the modification of known formulas to be used in Saudi Arabia is implemented.

Abstract Assessing distribution patterns of valuable taxa plays an important role in the biodiversity conservation of these taxa. The genus Crocus L. (Iridaceae) comprises about 100 species that are distributed mainly in the Mediterranean region and western Asia. The present study purposed to assess the distribution patterns of Iranian Crocus species (including C. sativus L. and 8 wild species) and their conservation status in Iran as one of diversity centers of Crocus in the Middle East. A set of geographic distribution data was compiled through field studies, and reviews of herbarium specimens, iNaturalist, and various Flora. Localities were marked on geo-referenced maps (1/106) of Iran using ArcView version 3.2 (Esri, 2000). The distribution patterns of the taxa were mapped per 0.25° × 0.25° universal transverse Mercator grid cells (25 km2 with the exception of boundary area). Based on the species distribution (SDI) (33%) and species specialization (SSI) (44%) indices, those Iranian Crocus species that are threatened are mainly distributed in Irano-Turanian region. The mountainous ecosystems of Almeh and Western Alborz are important distribution centers of these taxa. Iranian Crocus species with SSI < 0.5 (C. almehensis, C. gilanicus, C. michelsonii, and C. caspius) have the highest conservation value.

Salah satu usaha pemerintah dalam menyejahterakan masyarakat yaitu memenuhi kebutuhan pangan masyarakatnya. Pengendalian dalam penyediaan bahan pangan sangat diperlukan untuk dapat membantu dalam mengontrol distribusi bahan pangan. Dalam pengendalian penyediaan bahan pangan digunakan Gravity Location Models (GLM). GLM pada penelitian ini digunakan untuk menentukan suatu gudang yang berfungsi sebagai penghubung antara sumber-sumber pasokan dan beberapa lokasi sehingga dapat meminimalisasi biaya transportasi. Lokasi suatu gudang tersebut menggunakan koordinat geografis yang akan ditransformasikan ke koordinat UTM (Universal Transverse Mercator). Penelitian ini menggunakan data koordinat geografis pada Google Maps dan data jumlah penduduk, padi, jagung, dan ubi kayu Provinsi Maluku Utara Tahun 2014. Pengolahan data dilakukan secara manual dan menggunakan metode grid untuk mencari koordinat lokasi gudang atau lumbung pangan. Hasil dari perhitungan menggunakan (1) rumus  dan (2) metode grid adalah koordinat lokasi lumbung pangan yang memiliki biaya transportasi minimum di Provinsi Maluku Utara yaitu terletak pada Kabupaten Halmahera Timur.
