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.

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.
