    Survey of India Department of Science & Technology Rashtriya Manchitran Niti NATIONAL MAP POLICY 1. PREAMBLE All socio-economic developmental activities, conservation of natural resources, planning for disaster mitigation and infrastructure development require high quality spatial data. The advancements in digital technologies have now made it possible to use diverse spatial databases in an integrated manner. The responsibility for producing, maintaining and disseminating the topographic map database of the whole country, which is the foundation of all spatial data vests with the Survey of India (SOI). Recently, SOI has been mandated to take a leadership role in liberalizing access of spatial data to user groups without jeopardizing national security. To perform this role, the policy on dissemination of maps and spatial data needs to be clearly stated. 2. OBJECTIVES • To provide, maintain and allow access and make available the National Topographic Database (NTDB) of the SOI conforming to national standards. • To promote the use of geospatial knowledge and intelligence through partnerships and other mechanisms by all sections of the society and work towards a knowledge-based society. 3. TWO SERIES OF MAPS To ensure that in the furtherance of this policy, national security objectives are fully safeguarded, it has been decided that there will be two series of maps namely (a) Defence Series Maps (DSMs)- These will be the topographical maps (on Everest/WGS-84 Datum and Polyconic/UTM Projection) on various scales (with heights, contours and full content without dilution of accuracy). These will mainly cater for defence and national security requirements. This series of maps (in analogue or digital forms) for the entire country will be classified, as appropriate, and the guidelines regarding their use will be formulated by the Ministry of Defence.

April 2018 Updates Based on Adobe Reader DC version 2018.009.20050 In 2017, US Topo production systems were redesigned. This system change has few impacts on the design and appearance of US Topo maps, but does affect the geospatial characteristics. The previous version of this Users Guide is frozen in its current form, and applies to US Topo maps created The previous version of this Users Guide, which before approximately June 2017 and to all HTMC applies to US Topo maps created before June maps. The document you are now reading applies 2017 and to all HTMC maps, is linked from to US Topo maps created after June 2017, and https://nationalmap.gov/ustopo will be maintained into the future. US Topo maps are the current generation of USGS topographic maps. The first of these maps were published in 2009. They are modeled on the legacy 7.5-minute series of the mid-20th century, but unlike traditional topographic maps they are mass produced from GIS databases, and are published as PDF documents instead of as paper maps. US Topo maps include base data from The National Map and other sources, including roads, hydrography, contours, boundaries, woodland cover, structures, geographic names, an aerial photo image, Federal land boundaries, and shaded relief. For more information see the project web page at https://nationalmap.gov/ustopo. The Historical Topographic Map Collection (HTMC) includes all editions and all scales of USGS standard topographic quadrangle maps originally published as paper maps in the period 1884-2006.

  • 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.

  • (GIS)-Based Approach to Derivative Map Production and Visualizing Bedrock Topography Within the Town of Rutland, Vermont, USA

Van Hoesen Department of Environmental Studies, Green Mountain College, One Brennan Circle, Poultney, VT 05764, USA; E-Mail: [email protected]; Tel.: +1-802-287-8387; Fax: +1-802-287-8080 Received: 17 December 2013; in revised form: 21 January 2014 / Accepted: 22 January 2014 / Published: 29 January 2014 Abstract: Many state and national geological surveys produce map products from surficial and bedrock geologic maps as a value-added deliverable for a variety of stakeholders. Improvements in powerful geostatistical exploratory tools and robust three-dimensional capabilities within geographic information systems (GIS) can facilitate the production of derivative products. In addition to providing access to geostatistical functions, many software packages are also capable of rendering three-dimensional visualizations using spatially distributed point data. A GIS-based approach using ESRI’s® Geostatistical Analyst® was used to create derivative maps depicting surficial overburden, bedrock topography, and potentiometric surface using well data and bedrock exposures. This methodology describes the importance and relevance of creating three-dimensional visualizations in tandem with traditional two-dimensional map products. These 3D products are especially useful for town managers and planners—often unfamiliar with interpreting two-dimensional geologic map products—so they can better visualize and understand the relationships between surficial overburden and potential groundwater resources.

  • 49 Chapter 5 Topographical Maps
    Topographical Maps Chapter 5 Topographical Maps You know that the map is an important geographic tool. You also know that maps are classified on the basis of scale and functions. The topographical maps, which have been referred to in Chapter 1 are of utmost importance to geographers. They serve the purpose of base maps and are used to draw all the other maps. Topographical maps, also known as general purpose maps, are drawn at relatively large scales. These maps show important natural and cultural features such as relief, vegetation, water bodies, cultivated land, settlements, and transportation networks, etc. These maps are prepared and published by the National Mapping Organisation of each country. For example, the Survey of India prepares the topographical maps in India for the entire country. The topographical maps are drawn in the form of series of maps at different scales. Hence, in the given series, all maps employ the same reference point, scale, projection, conventional signs, symbols and colours. The topographical maps in India are prepared in two series, i.e. India and Adjacent Countries Series and The International Map Series of the World. India and Adjacent Countries Series: Topographical maps under India and Adjacent Countries Series were prepared by the Survey of India till the coming into existence of Delhi Survey Conference in 1937. Henceforth, the preparation of maps for the adjoining 49 countries was abandoned and the Survey of India confined itself to prepare and publish the topographical maps for India as per the specifications laid down for the International Map Series of the World.

    Numbering System 0f Topographical Maps by Prof. Subhas Manna, Department of Geography, Narajole Raj College Topographic maps are an essential part of the field of geology due to the comprehensive analysis of a particular surface. Students can explore more about the topographic map here. Definition and Meaning of Topographic Map A topographic map is a map that represents the locations of geographical features. Furthermore, these geographical features can be mountains, valleys, plain surfaces, water bodies and many more. Topographic maps refer to maps at large and medium scales that incorporate a massive variety of information. All the components of topographic maps carry equal importance. Topographic maps refer to a graphical representation of the three-dimensional configuration of the surface of the Earth. Moreover, such maps show the size, shape, and distribution of landscape features. Also, such maps present the vertical and horizontal positions of those features whose representations take place. Most noteworthy makes use of contour lines so as to show different elevations on a map. Structure of Topographic Map Topographic maps have a detailed and compendious structure. The various aspects of a topographic map can be divided into three major groups: Relief: The depiction of the relief aspect is with brown contour lines that represent the mountains, hills, valleys, plains, etc. The elevations are available in meters (or feet) above the mean sea level. Furthermore, there are also spot elevations are shown in the black colour. Moreover, in these spot elevations, the marking of the lake level, the summit of a hill, or the road intersections takes place for the purpose of elevation.

Prof. Centre for Geo-informatics Topographic Map • map characterized by large-scale detail and quantitative representation of relief, usually using contour lines • Traditional definitions require a topographic map to show both natural and man-made features • A topographic map is typically published as a map series, made up of two or more map sheets that combine to form the whole map. Need & scope • Topographic surveys were prepared by the military to assist in planning for battle and for defensive emplacements. As such, elevation information was of vital importance. • As they evolved, topographic map series became a national resource in modern nations in planning infrastructure and resource exploitation. • By the 1980s, databases of coordinates that could be used on computers by moderately skilled end users to view or print maps with arbitrary contents, coverage and scale. (Google Terrain Maps [non satellite image]) Uses of topographic maps • Topographic maps have multiple uses in the present day: any type of geographic planning or large-scale architecture; earth sciences and many other geographic disciplines; mining and other earth-based endeavours; and recreational uses such as hiking or, in particular, orienteering, which uses highly detailed maps in its standard requirements. Topomap conventions • The various features are represented by conventional signs or symbols. These signs are usually explained in the margin of the map, or on a separately published characteristic sheet. • conventionally show topography, or land contours, by means of contour lines. • These maps usually show not only the contours, but also any significant streams or other bodies of water, forest cover, built-up areas or individual buildings (depending on scale), and other features and points of interest.

Making decisions based on geography is basic to human thinking. Where shall we go, what will it be like, and what shall we do when we get there are applied to the simple event of going to the store or to the major event of launching a bathysphere into the ocean's depths. By understanding geography and people's relationship to location, we can make informed decisions about the way we live on our planet. A geographic information system (GIS) is a technological tool for comprehending geography and making intelligent decisions. GIS organizes geographic data so that a person reading a map can select data necessary for a specifi c project or task. A thematic map has a table of contents that allows the reader to add layers of information to a basemap of real-world locations. For example, a social analyst might use the basemap of Eugene, Oregon, and select datasets from the U.S. Census Bureau to add data layers to a map that shows residents' education levels, ages, and employment status. With an ability to combine a variety of datasets in an infi nite number of ways, GIS is a useful tool for nearly every fi eld of knowledge from archaeology to zoology. A good GIS program is able to process geographic data from a variety of sources and integrate it into a map project.
