Electronic maps, From the last quarter of the 20th century, the indispensable tool of the cartographer has been the computer. Much of cartography, especially at the data-gathering survey level, has been subsumed by Geographic Information Systems (GIS). The functionality of maps has been greatly advanced by technology simplifying the superimposition of spatially located variables onto existing geographical maps. Interactive, computerised maps are commercially available, allowing users to zoom in or zoom out (respectively meaning to increase or decrease the scale), sometimes by replacing one map with another of different scale, centred where possible on the same point. Mobility satellite navigation systems are computerised maps with route-planning and advice facilities which monitor the users position with the help of satellites.
Fire Insurance Maps During the late nineteenth and early twentieth centuries, fire insurance maps were periodically drawn up for cities and towns in the United States. These maps were commissioned by insurance companies in order to more accurately calculate fire risk, depicting the layout of the town and showing each existing building. The maps offer a great deal of information, and can show the outline of the building, the building material, the number of stories, doors, windows and chimneys, the address and lot lines, street widths, water pipes, hydrants and cisterns. The Sanborn Company was the largest, but not the only, fire insurance mapping firm. The Sanborn Company was founded in 1867, and created fire insurance maps from 1867 until 1969.
Maps are so ubiquitous that we forget that we use maps on daily basis. The signage, the road mile stones, the directions that ask are basically maps in the making. Yes we make maps in our minds. Once you put these on paper or on electronic media, these become hard copy or soft copy maps. Maps basically fall in two categories, the raster and the vector maps. Raster maps are images of paper maps, it can be said to be similar to photographs. Can you edit them, yes but very difficult to control each aspect of raster maps layout and designs. Then how do we edit the maps and control all design and layout aspect? The answer is vector maps, these are intelligent maps which are basically made of three entities, points, lines and shapes. The points are symbols of hospitals, schools etc. The lines represent all entities which are denoted by paths like roads, railways, streams, contours etc. The area or shape comes in for parks, large water bodies, and even your home or office building if is a small scale map. Yes small scale map; smaller the scale larger is the detail on the map.
The use of different learning styles within the classroom has long been a core teaching strategy, and with the exam season upon us again, the need to find effective methods which allow learners to condense key information into memorable chunks becomes even more pressing. Keywords are a useful starting point, but adding structure to these is important if disparate pieces of information are to be linked into a coherent story. This is where visual mapping can play a key role. Although most people viewing a mind map or concept map will initially consider the words themselves to have the most importance, positioning of these words within the diagrams also holds key information. In mind maps, the overarching idea of the diagram will be found at the centre, with topics of reducing levels of importance radiating out from this until the detail resides at the edges. Related wedges may be shown by the use of different colours, and pictures and other aide memoire are also recommended to bring the creative mind into play. Links, in the form of simple lines, usually show a number of branching pathways radiating out from the centre, giving a spider web structure to the final map.
Some possible applications using interactive maps on websites including: Retail Shops / Branches Locator: A web-based interactive flash map can help your customers to find the nearest retail shop or branch location in few mouse clicks. For example, you can use an interactive map of United States on your website, with pushpin buttons to pinpoint all your retail shops, hotels or any other type of facilities. Your visitors can make selection simply by clicking on a pushpin button, and then he can see the list of options available including address and contact details. Interactive Real Estate Map: A real estate website can use interactive flash maps to display available properties on state, county or city maps. Push pins of different colors and shapes can be used to pinpoint residential properties, commercial properties, resorts, apartments, corporate offices, and more. Hover over effects can be included which can provide additional pop-up information about a particular property.
The concept map, by contrast, has a top down hierarchical structure. A concept map requires both a context and a focus question, from which it should not deviate. It covers a domain of knowledge, and its creator, Joseph Novak envisaged that the development of a concept map would be undertaken by an expert in the field who would sift and sort the relevant keywords, giving them a rank value based on generality and inclusivity. Following this the words would be layered and linked, enhancing simple straight line linkages with additional written indications of relationships. It is interesting that increasingly mind maps also have writing along the linking lines (in addition to the keyword) - it seems that a simple line does not always convey enough information about relationships when the user is not simply using the diagram as a revision aid. As with mind mapping software, it is possible to use cmap tools to develop these concept maps for yourself. If you lack the confidence to start at the expert level, I cover here one more mapping type which may be of use.
