Conformal projection: These projections maintain angular relationships and show accurate shapes while covering small areas. Such maps are useful for navigational or meteorological purposes where angular relationships are important. Equidistant projection: Maps that maintain accurate distances along given lines or from the center of the projection are based on this principle of equidistant projection. Such maps are used for navigation and for radio and seismic mapping. The Equirectangular projection and the Equidistant Conic projection are two examples of this category. Azimuthal (or zenithal) projection: A projection that maintains accurate angular relationships and directions from a given central point use this projection. Maps for aeronautical purposes use this principle. The Lambert Azimuthal Equal-Area projection and the Gnomonic projection are examples of how azimuthal projection is used for map making.
Many but not all maps are drawn to a scale, allowing the reader to infer the actual sizes of, and distances between, depicted objects. A larger scale shows more detail, thus requiring a larger map to show the same area. For example, maps designed for the hiker are often scaled at the ratio 1:24,000, meaning that 1 of any unit of measurement on the map corresponds to 24,000 of that same unit in reality; while maps designed for the motorist are often scaled at 1:250,000. Maps which use some quality other than physical area to determine relative size are called cartograms. A famous example of a map without scale is the London Underground map, which best fulfils its purpose by being less physically accurate and more visually communicative to the hurried glance of the commuter. This is not a cartogram (since there is no consistent measure of distance) but a topological map that also depicts approximate bearings. The simple maps shown on some directional road signs are further examples of this kind.
It is estimated that almost $800 billion will be spent on travel and tourism in 2011 and nearly two billion business and leisure trips will be made in the United States alone. How will these travelers discover where to stay, eat, shop and play? How will they learn about the businesses in your town? When I travel or visit a new place I look for fun and informative maps to help me plan my trip before I go. I want to learn a little about the area, find places to stay, and know what to expect when I get there. Once I arrive at my destination I need an easy way to find nearby attractions, restaurants and other businesses. Getting a sense of the neighborhood and some background information makes my visit more enjoyable. An interactive map can display photos, videos and descriptions of hotels, points of interest, historic sites, shopping areas or museums, and you can click right from the map to advertiser web sites to book accommodations or get more details. Does your community have an interactive map to promote tourism?
Mapping is an art and science. Art because it represents our piece of earth in an artistic way. And science because the representation has to meet exacting standards. Say for a map on a million scale, things lesser than a few hundred meters will be just points. So many small lakes may just disappear on a million map and similarly many small roads will just not show up. Just try zooming in and out on Google Maps to see how it behaves. You want to see some maps just go over to www.mapsandlocations.com. It describes different types of maps. You can also ask for an editable PDF or Illustrator map from the site administrator to experiment with. And how would you edit the PDF or Illustrator map, well just download fully functional Illustrator CS3 from Adobe Website. You can also use Macromedia Freehand for editing vector maps.
The key is knowledge, so you will need to learn as much as you can about the individual maps you are hunting for. I suggest you choose a subject of cartography or a historical period you may interested in learning about. Consider maps made during the American civil war, maps of the Republic of Texas, maps of Scotland if you are of Scottish ancestry or maps of Rome if you went there on honeymoon. For example, your adoptive child is from China then you can concentrate on maps of China. The options are limitless. The idea is that within each field there will be a few fairly rare and desirable maps that can fetch some good money when sold at auction. When you have become acquainted with the current sale price of your selection of maps you will need to consider condition and editions. By this I mean a specific edition, of a specific year for a map in good condition with no tears, water stains, major repairs and has good color. By the time you have done the things described above you will have a fair amount of knowledge about the world of antique maps. You will now be starting your hunt. In your hunt you should go to all the consignment shops and thrift stores in your area. Visit antique stores and old book stores and ask to see if they have old maps. By doing this you will get to handle antique maps and get a feel for them.
For the cities themselves you can just rely on the maps mentioned before, but when it comes go move from one to the other, its a good idea to get small but detailed maps where you can find your route. Of course, if you travel by train, an inter-rail map would be the best. If you go by road, a good idea is to avoid buying any maps and use the Google Earths function that allows you to write two cities and the program finds with detail the best route possible. Print out the screen and the indications or copy it in a paper and theyll be great value. Finally, if you are going on a trip that includes many countries, you can find the best travel maps by using the system mentioned above for road travel. Instead, for rail travel I would encourage you to get one single map for every country as maps for a whole continent will be far less the detail grade you expect them to be. If you are going to Europe, a good idea is to get also the timetables for all European departures getting the Eurail timetable that gets published every year. In any case, when you are looking to select one map or another, the best deal will always be the most simple one. A map loaded with data and details of everything is confusing and will get you tired. When looking for the best travel maps you need to find in the map only what is interesting you and nothing else.
