How to Read a GPS Mapping System The most common way for a GPS receiver to display your global location is with a plot screen, using a series of waypoints in the area. So that you can track your position logically, you should always set the plot screen directions so that north is up, or towards the top of your device so it reads like a map. The device will allow you to navigate through the GPS map, zooming in and out or even shifting the maps location. The GPS database will allow you to save various waypoints, typically at least one hundred, and label them with brief descriptions. Your waypoints and their names can help plan routes quickly in the future.GPS devices come with a map datum already installed. This is a basic representation of the land formations in the country or area where the unit was designed. GPS units manufactured in the United States are installed with North American map datum, so it is necessary to install additional software if the unit will be used outside the country.
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.
These arent like those maps you get at the gas station when you need to get from Topeka to Las Vegas. They offer more than just the highways and byways of the roads. Instead, a good atlas will give you the important information in addition to the means to travel from one place to another. Many a traveler has their travel map pinned up on the wall with many brightly colored pins sticking in the destinations they have visited. Sometimes the pins are coded in a way that says something like "Red is the places I have been, Blue is the places I have lived, and Yellow is the places I want to go someday." Of course the color scheme is different depending on what you like or want to say about the map on your wall.
This conveys to the visitor a sense of belonging, a sense of direction, that your business is located in the West or East or North or South. In all probability he will remember the general location and what your business ddeals with, better than the words of the address. We humans have a way with pictures. Now the question comes, how to get the map and then how to edit it as suited to your requirements. There are many mapping sites which provide you with outline maps at low costs. You can visit them and buy these fully editable maps and feed your specific information and use it in your website. But what you need is a small country outline map, why pay $50 or more to an online mapping site for it. Yes you are right. A country outline map should be available for $20 or may be $10 or even free. So how do you create a free map for your site. Just go over to Google Earth or Google Map, display your countrys full extent, save the screen as image. Now use Adobe Illustrator or Macromedia Freehand to vectorise the outline. You got your vector country outline map. Add the relevant information and use it the way you want. All simple maps can be easily created by this method but for big and complicated maps you need cartographers or map makers. All maps can not be produced by just drawing lines, you need GIS exports, some re-specifications, may be some adjustments and a pleasing design which conforms to the use of the map. No wonder, map making is a lovely amalgamation of art and science.
There are other options worth knowing about: firstly the Active Maps which come in both Landranger and Explorer ranges and have a laminated, waterproof cover to protect your map from the rain and elements when out and about; secondly there are the custom-made maps which allow you to choose where the centre of your map will be. These are particularly handy if the route you want to follow will require buying 2 or more maps or you want maps of the countryside surrounding one central point on all sides e.g. the area around a campsite or accommodation or even your house! Both types of map are more expensive than basic OS Explore and OS Landranger maps. Check your whole walk area is covered: Select the type of map you require and then check on the map detail that your whole route is covered. The last thing you want is to realise that half your intended route is missing when you set off for your walk! If necessary you will need to get additional maps for adjoining areas. Each map has a number in the top right hand corner of the cover which along with the name is the reference you will need to select the correct map to purchase.
Chennai, the capital of the Indian state of Tamil Nadu, presents an outstanding blend of traditionalism and modernity. It is regarded as the cultural hub of South India and the Detroit of India, both. Ancient temples, long traditions of music, arts and dance, and age-old customs make it the foremost place in South India to understand the regional culture. Modernity, on the other hand, is reflected in its being a major IT hub in the country and the choicest city for the automakers to build their main manufacturing units. The tall skyscrapers and contemporary buildings will convince you of the same. The fourth most populous metropolitan area in India, Chennai is only the third, after Mumbai and Delhi, in the number of expatriates in the country. Definitely the most sought-after city in South India, it has been ranked as the only city in South Asia to go around the world by a leading international journal.
