Maps and their Uses

yes well hey Paulie come take a look at the real property you want woods and hills in the lake yeah Jack wants a golf course mother wants good shopping centers and I want good highways into the city it may not be easy to satisfy everybody but we can try with these maps well how about well let's think a minute what is a map after all we might say a map is a miniature a picture of some large area telling us many things along the edges is a grid to help us locate certain places special places on the map are marked with symbol down here in the legend we find the explanation of these symbols and by looking at the scale we can measure distances on the map in this way a map presents a condensed selective picture of an area for example look at this part of the map if you were to stand there and look north this is what you would see you can't tell much from this point of view can you well then let's go up in the air now we can see a bit more when we go higher we can see better more streets and railroads but there's almost too much to look at and nothing can be identified by name or number if you could see a miniature picture of this and if you could identify important things you'd never get lost with you well that's what a map does for you it gives you a straight down view of only the important details with lettering and a legend a grid and a scale to learn about those things let's sit in with a Smith after supper well let me find myself first now let's see where are we now oh there's the lakefront and there's the park but we're not far from there some berries foster out oh yes and this block would be the one with its cool and about here's our apartment what did he got me well let's look over here now the legend of a map explains the symbols it uses imagine Oh motorcoach region well that must be the bus line then well let's see I want to find a town Highland Park you suppose it's here no let's get on this map that shows all the suburbs now here's the lake and here's the park and here's where we are on this map now to find Highland Park let's look up in the index Highland Park and we are h3 now that will show you where to find it on the map Oh like this there's eight and there's three so where they meet is Highland Park near the lake and just above the county line so that's where it is I've heard there's a good shopping center there shopping center hey I've got a special map for that say dad I found a honey of a golf course it's only one mile from a super highway to the city well it's worth looking into Jack but I'll bet there isn't much in the way of shopping around there where is that fair special man what is a special map let's say it is a map which selects a single kind of item to show for example different kinds of hospitals in this area the railroad terminals and yards of this area the water mains and sewers each map tells us one special thing we want to know here we are about it you see there are special symbols here to show the trade area centers and the sub centers that's just what I want isn't it here's Highland Park just above the county line and it is a shopping center but then so are some other places here and here look Poli we found some good sized suburbs we should investigate I found a lovely country with lots of hills the map it shows for example that this is fairly level gently sloping territory and here there are steeper slopes hills and ravines how do we know this how do we read a contour map suppose you wanted to make a map of this area right in the middle is a hill represented by this cone if you look straight down on the area it's hard to see the hill and impossible to guess how high it is so let's mark the height of different places we can draw a line around the hill at the height of 10 feet above the main level and another line 10 feet above that another line 10 feet higher lines at 10-foot intervals now see our Hill as it might look on a contour map of course most Hills are more irregular here's a hill for example that has one fairly steep side and one sloping side as shown on a contour map the closely spaced lines indicate a steep slope the widely spaced lines indicate a more gentle slope see and when we represent Hills on a flat surface with lines we might find something like this can you see other hills on the map and do you see why lines like this usually represent a ravine poly does she knows how to read a contour map now what have the different Maps told the Smith family now I am easy to please web transportation is all I want yeah or here or here and all I want a shopping center and a good one here or here here or here I just want beautiful country here or here I found three places that are good for recreation here here and here we've all chosen so by knowing how to read their maps the Smith's found a likely area for their house hunting of course there's still the matter of going there to look around and of using maps to find the way maps show distance and they show Direction maps present condensed pictures of areas picking out certain elements and showing them in symbols and if you read maps well you can use them for many purposes let's see what the Smith family found through their use of maps [Music]
