Some libraries carry the Sanborn maps on microfilm. Look up your property on the various maps and check for any existing house and outbuildings, such as a garage, shed or barn. The house number will be located at the front edge of the lot. Make note of the number as it was not unusual for the house number, or even street name, to change over the years. If you can find your property on a succession of maps, you can see how it changed over time. The fire insurance maps were updated somewhat irregularly, based upon the likelihood that enough had changed to make possible the sale of updated maps. However, when found, they can offer proof of the existence of your home and represent a unique snapshot of the community. Looking at maps can provide you with a unique perspective about the property you are researching, and can often offer new leads in your search for who lived in your home. Whenever you are at a library, government center or historical society, ask about the maps and atlases that are held in their collections.
Map projections are classified based on: Distortion characteristics: Some projections often need to show a particular area or its relative size accurately for distributions or other phenomena. These are called equivalent or an equal area projection. The Lambert Azimuthal projection that maps a sphere to a disk, and accurately shows all regions of the sphere is an example of this category. However, this equal area projection fails to represent angles with accuracy. The Albers projection is another instance of equal area map projection that utilizes two standard parallels. Despite no preservation of scale and shape, the distortion in this case is found to be minimal between the standard parallels.
The walk location is decided, you know how long you want to be out for and youve brushed up on your map reading skills. Its time to get a map and plot the route. In the UK this means using an Ordnance Survey map which shows all the footpaths, features and topographic detail you will need to complete any forray into the countryside safely and successfully. There is not just one Ordnance Survey map for each area however but a choice of different series of maps, all showing different levels of detail, scales or usages. So how do you select the right Ordnance Survey map for your walk? Here are a few pointers to help you choose: Select the correct map for your walk: You have two main choices of paper map - the Ordnance Survey (OS) Explorer or the Ordnance (OS) Landranger. Other maps are available such as street atlases, historical or specialised activity maps but for hiking or walking you will need one of the above in order to provide enough detail to navigate from.
More and more people are beginning to use GPS mapping as the primary way they plan, map, and track their trips for both business and for pleasure. With GPS maps, you can route trips to any destination, whether you are driving in your car with a vehicle GPS navigation system installed or hiking or biking through the wilderness with a handheld GPS mapping device. The GPS unit will connect with numerous satellites, receiving data and information about its location. The GPS tracking software will then use GPS mapping technology to create a GPS map that you can view and interact with. You can then plan routes and organize trips on your GPS receiver, as well as several other useful features. The various abilities and functions of the GPS database system is a primary factor of the cost of a GPS device.
Internal cross links between lower level keywords are less common in mind maps and concept maps than they are in association maps, with the branching tree structure tending to take precedence. With concept and mind maps, the relationship of each word to the overarching theme remains paramount. In association maps, however, the link becomes the key, and, as stated, the process of deciding which type of link joins keywords together is a valuable part of ascertaining correct understanding. If you cant link two keywords effectively, you havent understood how they are related to one another! This pairing and linking process allows a jigsaw like approach to the development of the knowledge map, and enables a student always to be working from a point of understanding. Most interestingly, when used to develop a map for a new topic where one is not an expert, it is possible to identify the high level terms which will take precendence at the top of a concept map once an association map has been developed. This is because they are the ones with the most linkages. Development of an association map therefore gives a useful mechanism for allowing students to take on the expert role and develop their own concept maps, even when they are not fully confident in a subject. Drawing any of the three types of maps involves much more active learning than just using ready produced ones in my experience so this is a definite bonus. In summary, all mapping techniques provide a powerful method for organising key ideas within a topic or sub-topic. Mind mapping allows colourful creativity, concept mapping provides the confidence of professional correctness, and association mapping always lets you get started somewhere, but I have a sneaky suspicion, that the real power of visual mapping is the process your brain goes through when you develop those non-verbal links for yourself, so get a pencil and get started!
The monetary value of many antiques is based on what a prospective buyer is willing to pay for them, so the value of antique maps will vary. There are plenty of people who are willing to pay high prices for old maps, so their potential value is very high, depending upon their condition, the year in which they were produced, and many other factors. There are old maps that are worth two hundred dollars each and old maps that are worth thousands of dollars each. Small details can make all the difference. Finding Antique Maps Many of the best antique maps are part of historical and private collections. Maps are not the most durable antique items in the world, so there are only so many antique maps available today. The further back anyone goes historically, the harder it will be to find old maps from that time period. One of the reasons that old maps are so valuable in the first place is the fact that they are so rare and so fragile. They are tiny pieces of history that can be easily lost and can easily fade with time.
