Marine Raster Charts are geo-referenced, digital images of Official Hydrographic Office and select private navigational charts. True color copies of the official paper chart of hydrographic services, marine raster charts are the most reliable, allowing you to display on screen the official paper charts that you were accustomed to use. Figure 1 - Raster chart © 1985-2012 MaxSea International Follow us at How to choose your nautical chart? Marine Vector Charts utilize a vector database to build the chart display. This data is stored in layers and records every nautical chart feature such as coastlines, buoys, lights, etc. These features and their attributes such as position, color, size, shape, and others are stored in a database allowing them to be selectively displayed and interrogated. In many areas of the globe where there’s no hydrographic service, vector maps are often the only reference.

Figure 3- Vector vs Raster nautical charts You have to determine first whether you prefer Vector or Raster marine charts. Indeed, it’s hard to say which one is the best format, it will mostly depend on the user personal preferences, habits and needs. Traditional paper chart users tend to like Raster Charts, since visually these are an exact reproduction of the paper chart. Vector Charts are stored as a database and drawn on the computer or plotter screen by the software, thus the display of a Vector Chart does not resemble a paper chart. © 1985-2012 MaxSea International Follow us at How to choose your nautical chart?

  • Chapter 13.2: Topographic Maps 1
    Chapter 13.2: Topographic Maps 1 A map is a model or representation of objects and terrain in the actual environment. There are numerous types of maps. Some of the types of maps include mental, planimetric, topographic, and even treasure maps. The concept of mapping was introduced in the section using natural features. Maps are created for numerous purposes. A treasure map is used to find the buried treasure. Topographic maps were originally used for military purposes. Today, they have been used for planning and recreational purposes. Although other types of maps are mentioned, the primary focus of this section is on topographic maps. Types of Maps Mental Maps – The mind makes mental maps all the time. You drive to the grocery store. You turn right onto the boulevard. You identify a street sign, building or other landmark and know where this is where you turn. You have made a mental map. This was discussed under using natural features. Planimetric Maps – A planimetric map is a two dimensional representation of objects in the environment. Generally, planimetric maps do not include topographic representation. Road maps, Rand McNally ® and GoogleMaps ® (not GoogleEarth) are examples of planimetric maps. Topographic Maps – Topographic maps show elevation or three-dimensional topography two dimensionally. Topographic maps use contour lines to show elevation. A chart refers to a nautical chart. Nautical charts are topographic maps in reverse. Rather than giving elevation, they provide equal levels of water depth. Topographic Maps Topographic maps show elevation or three-dimensional topography two dimensionally. Topographic maps use contour lines to show elevation.

  • Maps and Charts
    Name:______________________________________ Maps and Charts Lab He had bought a large map representing the sea, without the least vestige of land And the crew were much pleased when they found it to be, a map they could all understand - Lewis Carroll, The Hunting of the Snark Map Projections: All maps and charts produce some degree of distortion when transferring the Earth's spherical surface to a flat piece of paper or computer screen. The ways that we deal with this distortion give us various types of map projections. Depending on the type of projection used, there may be distortion of distance, direction, shape and/or area. One type of projection may distort distances but correctly maintain directions, whereas another type may distort shape but maintain correct area. The type of information we need from a map determines which type of projection we might use. Below are two common projections among the many that exist. Can you tell what sort of distortion occurs with each projection? 1 Map Locations The latitude-longitude system is the standard system that we use to locate places on the Earth’s surface. The system uses a grid of intersecting east-west (latitude) and north-south (longitude) lines. Any point on Earth can be identified by the intersection of a line of latitude and a line of longitude. Lines of latitude: • also called “parallels” • equator = 0° latitude • increase N and S of the equator • range 0° to 90°N or 90°S Lines of longitude: • also called “meridians” • Prime Meridian = 0° longitude • increase E and W of the P.M.

    CHAPTER 3 ANCIENT MARINERS BETWEEN EXPERIENCE AND COMMON SENSE GEOGRAPHY Pascal Arnaud Université Lyon 2 Abstract Although no first-hand information from ancient mariners have been preserved, their legacy to classical Greek geography has been so important that it is still pos- sible to recognise the structural impact of the material gathered from their implicit knowledge upon the patterns of presentation of space. The kind of tacit knowledge they had acquired appears very similar to that of the later Micronesians, studied by Hutchins. It was based upon durations rather than distances, and upon an original perception of orientations and directions. Thanks to that knowledge, based upon the repetition of experience through generations and apprenticeship, they were able to sail the blue sea without maps or instruments. This paper will address the issue whether – or within which limits – the mental construction of limited linear sec- tions of space may have opened the way to the construction of some coherent pre- sentation of space, a mental map in the fullest sense. In a well-known paragraph, Strabo1 establishes the direction and length of the passage between Rhodes and Alexandria and balances Eratosthenes’ calculations with ancient mariners’ experience: “The passage between Rhodes and Alexandria by north wind is about 4000 stadia; sailing along the coasts is twice this distance. Eratosthenes says that, this distance is the mere mariners’ conjecture of some, while others avow distinctly that it amounts to 5000 stadia; he himself, from observations of the shadows indicated by the gnomon, calculates it at 3750.” ‘Mariners’ were often scorned by ancient writers, when they were authors of travel narratives, but used to be considered as a main piece of evidence, when they were ano- nymous and a consensus came into being from a long-lasting verified experience of 1 2.5.24, C 168–169 = Erat.

    Indian Electronic Navigational Charts (ENCs) Programme: Marching Towards Self-Reliance Dr. U. K. Singh and Rajesh Kumar Civil Hydrographic Officer ([email protected]) Principal Civil Hydrographic officer Indian National Hydrographic Office 107-A, Rajpur Road, Dehradun (UA), INDIA-248 001 Tel: 91-135-2747365-211 (Extn.) Fax: 91-135-2748373 ABSTRACT : Marine navigational safety is the prime concern of Hydrographic Office (HO) in order to provide safe and efficient navigation and for the development of nation maritime policies. The efforts for safe and efficient use of hydrographic products and services have paved way for development of the Electronic Navigational Charts (ENCs). The recent developments in Electronic Navigational Charts(ENCs) and Electronic Chart Display and Information System(ECDIS) are panacea in this direction. With this pertinent ambition the Electronic Navigational Charting programme of India started in 1997 with a vision to gain a greater appreciation and understanding of the use of electronic charts when operating in its Waters. More than 206 ENC’s were generated for all 6 usage bands in short span of 5 years. This paper describes vision, initial accomplishments, production flow of ENC and future vision of Indian National Hydrographic Office (INHO) in development and marketing of its Electronic Navigational Charts. The paper also described the regional cooperation in production and setting-up of RENC for North Indian Ocean Hydrographic Commission (NIOHC). 1. INTRODUCTION : Navigation of ships through nation's coastal waters and channels using improved navigational systems and new navigation technologies is the prime concern of any Hydrographic Office (HO) in the world. HOs have been haunted in past years, by shipping disasters, which have questioned the safety of life at sea, both to the mariners and ocean environmentalists.

    Journal of Marine Science and Engineering Article Electronic Navigational Charts: International Standards and Map Projections Athanasios Palikaris 1,* and Athanasios K. Mavraeidopoulos 1,2 1 Hellenic Naval Academy, Navigation and Sea Sciences Laboratory, 18539 Pireas, Greece; [email protected] 2 National and Kapodistrian University of Athens, Remote Sensing Laboratory, 157 84 Athens, Greece * Correspondence: [email protected] Received: 4 March 2020; Accepted: 31 March 2020; Published: 3 April 2020 Abstract: Electronic navigational charts (ENCs) are geospatial databases, compiled for the operational use of Electronic Chart Display and Information systems (ECDIS) according to strict technical specifications of the International Hydrographic Organization (IHO). ECDIS is a GIS system designed for marine navigation according to the relevant standards of the International Maritime Organization (IMO). The international standards for ENCs and ECDIS, issued by the IHO and IMO, cover many aspects of the portrayal of ENCs in ECDIS but do not specify or recommend map projections. Consequently, in some cases, the unjustified employment of map projections by the manufacturers has caused certain functional drawbacks and inadequacies. This article reviews, evaluates and supplements the results of earlier studies on the selection of map projections for the depiction of ENCs in ECDIS and proposes a reasonable set of suitable projections with pertinent selection/implementation rules. These proposals took into consideration that ECDIS users (navigators) are

When descriptive legends do appear on nautical charts, they are generally quite similar from one cartographer to another, from one language to another (Latin, Catalan, Italian), and even across the centuries: there are some legends on early sixteenth-century nautical charts which are very similar indeed to the corresponding legends on late fourteenth-century charts.
