GPS proyect of geography

                                 THE GPS 

                                            By: Nathalia Michelle Basulto Margarito 7A
                                                                      WHAT IS A GPS?

It is a system that allows you to see the whole Earth, the position of someone or something with an accuracy up to centimeters, but are not as accurate. The system was developed by the United States Department of Defense to determine the positions. The GPS system has 24 satellites help and uses trilateration. The GPS is supported by a network of 24 satellites in orbit on the Earth, the satellites ar synchronized paths to cover the entire surface of the EarthIn reality, they needed at least 4 satellites to determine our position correctly, but let's leave that for later.

Each satellite transmits a signal which is received by the receiver, this, in turn measures the time it takes signals to reach it. Multiplying the measured time by the signal speed (the speed of light), we obtain the receiver-satellite distance (Distance = Speed ​​x Time).

However the satellite positioning is not that simple. Get precise measurement of the distance is not an easy task.                              
The distance can be determined through wave modulated codes sent by the satellite (C / A codes and P), or by analysis of the carrier wave. These codes are complicated. The receptor was prepared so that only those codes and decode any more, he is thus immune to interference from natural or intentional sources. This is one reason for the complexity of the code.            
  
                    ORIGINS AND CONTROL OF THE GPS NAVEGATION

the origins of this system must be placed in the field of defense of the United States of America. Department of Defense was in which developed and installed, and currently operates the system.

                                                            THE GPS FOR THE CAR

This allows drivers to use a very useful support when driving alone, especially when they are in cities or routes that had never happened and you do not know. GPS normally carry voice control for drivers are then easier to control when driving, this system keeps the driver's eyes on the road or path which is very convenient, if it finds a copilot, this can manually control as he says the says the driver directions.

                                                            THE HISTORY OF GPS

After World War II, the Defense Department efforts to find a solution to the problem of accurate, absolute positioning. It was several projects and experiences for 25 years. All possible to determine the position but were still limited is the accuracy or functionality. In the beginning of the '70s, a new project was proposed, the GPS.



The GPS has three components: the special, the control and user.

                                               

                                                TRIANGULATION OF SATELLITES

Although it may seem improbable, the general idea behind GPS is to use satellites in space as reference points for locations here on earth.

This is achieved through a very, very accurate, measuring our distance from three satellites, allowing us to "triangulate" our position anywhere on earth.

Let's forget for a moment about how our GPS said distance measured. We will see. Consider first as the measurement of these distances allow us to position ourselves at any point of the earth.

The big idea, Geometrically, is:

Suppose we measure our distance to the first satellite and found to be 11,000 miles (20,000 Km)

Knowing that we're 11,000 miles from a given satellite can not, therefore, be anywhere in the universe, but this limits our position to the surface of a sphere having that center satellite and whose radius is 11,000 miles.

Triangulation

Our position is calculated based on the measurement of distances to satellites
Mathematically away four measurements are needed to satellites to determine the exact position
In practice our position is resolved with only three measurements if we can rule out ridiculous answers or use certain tricks.
It requires however a fourth measurement for technical reasons that we shall see.

                                                  THE GPS IN THE SMATH PHONES

Smart phones have displaced traditional GPS navigators designed for cars. With its popularization, the "smartphones" have allowed each person has a tool to guide easy, intuitive, and as a great asset, their constant updating.
                                                             
                                                          THE PROCEDURE

The system is supported by at least 4 satellites, which send signals in order to identify the position and the clock of each. Thus, and according to these signals, the clock synchronizes sistea to calculate the time it takes to return to the team. And all this is done in seconds. After this operation, the system coordinates and grab handles, using software, to signal on a map once found the exact three-dimensional position are returned. One of its best features is that it works continuously and in any weather conditions.

                                              GPS IS FREE,  WHY?

Oddly enough, it is free, it is all business. If we focus, for example, in the GPS, which owns the Government of the United States, the way money is made is in the whole chain of actors who benefits from the satellite system: browser makers, mapping companies , application developers ... in the end, the fact that the use of GPS is free has generated an entire industry that moves millions of dollars and jobs.
       
                                                        MY OPINION

my opinion on this is that it is very interesting because the know how GPS works, because the GPS and stuff will think, but what most caught my attention is the why they did it for free, this topic is interesting when investigate about, that at first glance does not attract attention.

The GPS has pros and cons as:

pros: with GPS tracker cell, the 911 can help as they track you with that if you were kidnapped or something, can they find time ge

Location of places: go to a specific place without knowing how to reach him.
antitheft system: the GPS built into a device ensures your location in case of loss or theft.

Speaker: thanks to its built-in speaker can speak and indicate where we have to go to get to the right place.

Applications: Most GPS that exist in the market have included numerous applications such as calculator.

Easy to upgrade: stop update and add new maps or modifications just connect to the Internet and obtain update packages.

Detailed information: You can display various information about the journey as the distance remaining, fuel costs, the approximate arrival time, etc.

Cons:
High power consumption: GPS generates a high power consumption.

radioactive waves: emits radioactive waves that can become harmful to health by prolonged use of GPS.

GPS updated: it is necessary to always have the GPS updated to avoid problems of new roundabouts, blocked roads, road works, etc.

Hi my name is Carlo and today, I am going to show you all about planispheres. About what are they or what are their function in this world?  So I hope you enjoy and here we go.

What are planishperes?
It is representation of our world just like a map. Yes its that simple. There are many types of planisheres or representation in this case.

Types of planishperes :
Of the rivers of the world
The oceans
The countries ( our traditional map )
The city, if its an specific place of course. Ex: Mexico City, Guadalajara, Chiapas , etc…

Planishpheres can help you in many ways like being stuck in some type of road trip ad you don’t know where to go, just take out your google maps or even a physical one that in this case needs to be a planishphere of the roads of the place you need to go. It may also help you by locating you in the world, how ? By telling you how to go or what’s the best road to take.


Physical planispheres aren’t used so often now at days, people are buying more and more cell phones each day and that cell phone they buy has an app that can specifically tell you where are you. I’m not saying that it’s a bad thing to do or use of course I’m just saying that there used to be more physical maps of planispheres back at days.  

Geographical Features

                                                                                                                 Geographical Features

Hello my name is Maria Jose and on this blog I am going to talk about Geographical Features. Geographical features are landforms, ecosystem or human settlements, the human settlements are artificial geographical features and landforms or ecosystem are natural geographical features.Some examples of natural geographical features are:Volcanoes, mountains, rivers etc. And of artificial are:Chinese wall, Chichen Itza pyramids etc.

First lets understand what are natural geographical features, these is divide by two different types of natural geographical features:Landforms an ecosystems lets define this two terms.A landform is a surface form in a specific location, this are categorized by the location, elevation, type of soil, the objects that have.A ecosystem is a kind of biome were living things are located and their interact among them.


Now lets understand what are artificial geographical features, these are all the settlements or important structures that identify a specific area.
All natural Geographical Features are formed differently, the causes are similar:The movement of the tectonic plates, when the tectonic plates move, it create a movements on the earth’s surface, this movement create a different type of landform or ecosystem.

Some characteristics of natural geographical features are:It has land and soil, animal and plant life and weather and temperatures.

The artificial geographical features are made to represent an specific area, it is made to recognize a country, a city or an specific place.

Some characteristics of artificial geographical features are:It has something to express, how money is exchanged and where people settled.

This are some geographical features and some information:

Natural:

Mountains:A mountain is a landform that it extend to the sides and up, the causes of the creation of a mountain are an eruption of a volcano and the magma creates a new landform and some movements of the tectonic plates.


Rivers:A river is an course made of water that takes the water into a sea, ocean or lake, the rivers are on the groups of hydrological cycle.

Artificial:

Eiffel Tower:It is a tower designed by Gustave Eiffel on 1887-89, it was created for a World’s fair.The tower is meters 324 tall, the upper platform is 270 meters tall, it is a geographical feature because it represents a place.

Golden Gate bridge:It is a bridge with the measure of long of 2.737, it was begin on the 1933 and end on the 1937, it is a wonder of the modern world, this bridge represents San Francisco,California.



This is my personal opinion,I did not now about geographical features I only say the name of the natural geographical feature, I also did not now that are artificial geographical features I now until I was like on the half of the project.

I think that it is important to now how to call the things and to now how the things were created not to only now what are the things,I learn new things on this project now I now how to call the landforms that are made by the nature and how to call the landforms or monuments that are made by humans.

My opinion is that this I would use it on my daily life or on the school, some examples are on projects and when I see a geographical feature I would now how it was created, and why.First I do not like the theme but now I think it is interesting to now about the process or history of the things.

My favorite part was when I write about some examples of the geographical features because I understand more the theme because with the examples I give an idea to myself.

My favorite geographical feature is the Golden Gate bridge because I was surprised about the measurements and the little bit time it takes to do it, I also did not now that it was a wonder of the modern world.

So for me geographical features are landforms or ecosystem that are striking and it is made bye the human or the nature.

Then  for me natural geographical features are the landforms that the earth do by the movements of the tectonic plates, maybe it is not directly the cause of the tectonic plates but if you start to think why it pass a thing that create the geographical features maybe are the tectonic plates.

Finally for me artificial geographical features are big monuments or landforms created by humans  that represent a country or an specific place.

What I like the most of the mountains is that there can be created by two ways and I think the other way was impossible, the way is that it creates with an volcanic eruption.

What I like the most of the river is that it use the hydrological cycle,I did not now what it is it and I investigate and I think it is interesting.

What I like the most of the Eiffel Tower was that the tower was for a World’s fair, I mean it has an specific reason to construct it.

And finally what I like the most about Golden Gate bridge like I say it before was the measurements and the little bit time it takes to do it.

So I like a lot the topic, I learn new things and I would not like that my topic was something that I already now, I like to learn new things and to practice my ability to right and yo investigate.

Natural Elements

18/10/16
Hello my name is Pablo Covarrubias Delmar 7B  and in this Project I am going to talk about Natural Elements.

                    Physical Geography  
                            

Physical Geography or ( physiography ) is a branch of natural science that studies the spatial patterns of weather and climate, soils, vegetation, animals, water in all its forms, and landforms and this is associated with the issues of the atmosphere, lithosphere, biosphere, pedosphere , and hydrosphere.This sub-field of Geography is academically known as Human-Land Tradition.

Scope of Physical Geography

Physical Geography's Scope is much broader than the simple spatial study of nature. It also involves the investigation of how humans are influencing nature. Academic studies of Physical Geography and other related earth sciences are in fact specialized in their fields of knowledge and tend to focus themselves in one of the following well defined areas of understanding in physical geography:

Geomorphology - studies the various landforms on the Earth's surface.

Pedology - is concerned with the study of soils.

Biogeography - is the science that investigates the spatial relationships of plants and animals.

Hydrology - is interested in the study of water in all its forms.

Meteorology - studies the circulation of the atmosphere over short time spans.

Climatology - studies the effects of weather on life and examines the circulation of the atmosphere over longer time spans.

The concentration in Physical Geography is structured with a strong background in the natural sciences and expertise in three main topical areas of Physical Geography: 1) Vegetation Science , 2) Hydrology and 3) Climate.

Vegetation Science: It studies the process of growth
in plants: development, growing, growth, maturation, ontogenesis, ontogeny, or  the process of an individual organism growing organically of a purely biological unfolding of events involved in an organism changing gradually from a simple to a more complex level.

Hydrology: It studies the circulation, distribution, and properties of the waters of the earth on its atmosphere and their relationship with the environment within each phase of the hydrologic cycle. The water cycle, or hydrologic cycle, is a continuous process by which water is purified by evaporation and transported from the earth's surface (including the oceans) to the atmosphere and back to the land and oceans.

Climate: It studies the statistics of weather, usually over a 30-year interval. It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time.











Location
                 
What is location ?
Location is the exact description of where something is located. Every place on the Earth has an specific location, we use maps to find specific locations they are different types of maps that show different things.

For example, when you drive of one place to another, it means that you already are in a different location. It exist many types of things that helps you to arrive to another place for example a map, a GPS and many other things.




Types of things that help you to guide?

What is a map ?
A map is like a big type of a paper and it has all the continents with the way to arrive to anotplace. For example: you are in California and you want to go to Florida and you don't know so you can buy a map for guide you.

What is a GPS ?
The word GPS means Global Positioning System and are satellites that circle the earth and shows you any place were someone or something is located or ubicated.

What is a compass?
Is an navigation tool that shows you the north, south, east and west. The compass most use it in the navigation because the maps can not helps you too much, the same with the GPS.



That are some tools that you can use to know were are you located ore to know how to arrive to another place and the tool that you can use for the navigation.

This are some types of location:

What is an absolute location?
An absolute location is its exact place on Earth, often given in terms of latitude and longitude. For example, the Empire State Building is located at 40.7degrees north (longitude), 74 degrees west (latitude).

What is an geographical location?
Geographical location refers to a specific physical point on the Earth. This is more specific than "area" or "place," defined by a set of latitude and longitude coordinates.




So, that are some types of location, there exist more but I want to put that ones.



MY OPINION OF LOCATION

I liked the topic but is a simple topic, I will like to have another topic like what happens if the planet stop to rotate and that is so interesting for me and for other people.

And finally, this was my presentation I hope you enjoy it and also I hope that help you to find the thing that you was searching for. This project was made by :"Valeria Sanchez" of 7 grade.
