Digital Maps
In this frequently changing and updating pages, we wil let you know the
subjects which are highly voted. But for the first time, we will choose the
subject and that is 'Digital Maps.'
Digital maps are the datas of geography and man - made shapes on earth
saved by different projcetion methods using vertical and horizontal scales.
Digital maps are like stacks of numbers when considered their structure.
Digital maps are used generally in applications where engineering
calculations are made and miltary area successfully. But in order to
clarify why Software programmers deal with that we have to mention other
usage areas too. You guess that, is that right? :=)
Yes Simulation. Either military simulation or commercial purposes
simulations are used effectively in softwares.
It is widely used in military areas regarding guidance of weapons,
efficiency and testing envirenment. And either in the planning process of
military operations or during the operations, when decision making process
is in evaluation. In this type of very important stages very detailed maps
are used. For example, 1m or 1 cm detailed maps. But the other usage
methods which are less important than those require less detailed maps
like 100m or 250 m detailed maps.
Digital maps are widely used in commercial areas like pilot and driver
training. Also in virtual testing of cars in automative and other
important areas. But we think that it is not used as wide as it is needed
to be in Turkey.
For example the wide use of digital maps in trainin of drivers would
decrease the number of drivers who both have driver license and cannot
stop thir car near the gas pump in Gas Stations.
We evaluate that you will forgive us for funny example.
We can list the frequently Asked Questions respectivey in the following
part.
1. what are the Digital map types?
There are many types of digital maps according to their usage area.
Because their details are changing due their usage areas their formats and
types are various. But in general digital maps are divided into 2 groups;
a. Digital elevation Data,
b. Digital Feature Data.
2. What does Digital Elevation Data mean?
Digital elevation Datas are the mathematical representation of earth
geographic shapes. Those shapes are saved in different detail formats
ranging from cm to km.
3. What Does Digital Feature Data mean? Digital Feature Datas are the
mathematical representation of man-made and geographic features on earth
like roads, rivers etc.
4. Are there any more formats other than these? Yes there are different
formats other than those. Especially due to the developments in satellite
and information technology, the media is getting bigger to store more
information. Thus, the formats are changing very rapidly.
5. How can I own a digital maps? although there are different ways to
have digital maps, it can be seriously dangerous when it is passed
to bad guys. For that reason, by changing to world countries theyhave
different security categories. Each country have their own defense
agencies and different commercial companies produce digital maps.
6. Can I fnd an example data? Yes you can. either on the internet or
other sources you can have a digital map where they do not belong to any
geography on earth.
In the next couple of days we will have more documentation here where
we will have example formats, reading methods, and usage methods. But due
to the needs of extra working days to explain clearly on a sample, we need
a little time. Because we still work on our project too.:=).
Knowing is not always a degree of teching....
