How maps are created? And 6 Different Types of Maps
Making a every map requires similar steps. Here may be a a number of the main steps involved in producing a map. Where does one get the info to place on a map? Now we have discussed How may be a map made in 2020?Geo spatial professionals can collect and evaluate map information first-hand through field work, or second-hand from existing maps, aerial photographs, statistical reports, or computerized data files. does one need to start with a blank display screen every time? most maps now start with a base map that isn’t created specifically for the map that’s being made.
In most cases, someone (often the local, state, or federal government) has already compiled detailed digital information, like streets and rivers and limits , which information is out there for map makers using GIS.
Sometimes, the cartographer must purchase data from a “vendor” if the map is basically specialized. Because no map or analysis is any good without accurate data, it’s important that databases are developed consistent with rigorous standards and punctiliously edited and maintained. So let’s say I even have all this information – I’ll just make a map.
What’s the large deal? There are tons of choices that a cartographer has got to make when it involves designing the map: how should the round earth be transformed to the flat page or screen (map projection), what size and extent should the map cover (scale), what colors and shapes should get on the map (symbols), how will it’s printed or displayed? Fortunately, with computers, cartographers can now try a bunch of map design choices – not goodbye ago, each change was really time-consuming and expensive. then the map is printed? many maps finish up on paper in how – some using computer-driven printers and plotters, others using lithography . But nowadays there are many digital ways to display the ultimate map. and therefore the design of digital maps is different from those made on paper, and there are tons of various digital formats.
Imagine how different maps need to look if they’re designed for in-car GPS navigation system screens, or tiny telephone displays, or online mapping applications, or video games. tons of recent mapping are going to be digital, and it’s an honest idea to be familiar and cozy with computers – and even programming – as a future geospatial professional.
Types Of Maps
There are 6 Different Types of Maps:
1. Political Map
- A political map shows the state and national boundaries of a place. A political map does not have any topographic features.
- It also shows the location of cities, with respect to each other.
2. Physical Map
- A physical map is one which shows the physical features of a place or country, like rivers, mountains, forests and lakes.
- The physical features are usually shown in different colors.
- Rivers and lakes are shown in blue, places of low elevation are shown in dark green and as the elevation increases, the color becomes light green and eventually orange.
- Mountains are shown in brown.
3. Topographic Map
- Topographic maps are similar to physical maps, which show the physical features of an area. Although in topographic maps, differences in elevation and changes in landscape are shown with the help of contour lines and not colors.
4. Climatic Map
- A climatic map shows the information about the climate of different areas.
For example it shows areas which receive more rainfall or snow, or which have dry weather. - It uses colours to depict areas with different climate.
5. Economic Or Resource Map
- Economic or resource maps show the different resources present in the area or economic activity prevalent.
- They show the kind of crops that are grown and the minerals found in places.
- Symbols and letters are used to depict the activity or resource present in the area.
- Road Map
- Road map is the most widely used map which shows different roads, highways or railways present in the area.
- It is a very detailed map and is generally used for direction purposes.
- Road maps are usually made individually, city-wise.
- There are road maps present for an entire country too, but they cannot be made very detailed.
