Object and method of Geography: Meterology
Object and method of Geography:
Meterology: science that studies atmospheric phenomena with a view to predicting the state of the weather.
Geology: science that studies the history of the Earth, its structure, the materials that make it up, its nature, form and origin.
Sociology: Science that studies social phenomena. Geomorphology: science that studies the Earth's relief forms.
Demography: science that statistically studies the population.
Climatology: science that studies the climates on the Earth's surface.
Biology: science that studies living beings .
Economy: science that deals with the production of goods and services, the circulation of wealth and the redistribution of income.
In administrative terms
In administrative terms, the Portuguese territory is divided into 18 districts and 2 autonomous regions, each consisting of municipalities and parishes. The parish corresponds to the smallest administrative division, with each municipality having at least one parish, with the exception of the municipality of Corvo, in the Autonomous Region of the Azores, which does not have a parish.
Districts: administrative division created in Portugal to replace provinces and districts.
Municipalities: administrative division hierarchically lower than the district. It has a mayor.
Parishes: subdivision of a municipality. It has a Parish Council president.

Scale Problems When using a map we may have to calculate
Scale Problems
When using a map we may have to calculate:
THE REAL DISTANCE, knowing the distance on the map and the scale of the map;
THE DISTANCE IN MPA, knowing the real distance and the scale of the map ;
THE MAP SCALE, knowing the distance on the map and the real distance.
Working with scales: Large-scale map
Working with scales:
Large-scale map: it is a map that represents a small area, in great detail.
Small-scale map: it is a map that represents an extensive area, with little detail.
Larger scale: the one that allows you to obtain a map where the size of the representation is closer to reality.
Smaller scale: the one that allows you to obtain a map where the size of the representation is further away from reality.
Fundamental elements of maps: Maps are flat terrestrial representations
Fundamental elements of maps: Maps are flat terrestrial representations. Therefore, they are a fundamental tool for the geographer. But in order for them to be used and interpreted, they need to have a set of fundamental elements, which are essential for their reading. The elements are:
Title: indicates the subject to be analyzed, the region, the country or the type of map.
Orientation: is given by the cardinal points on a compass rose or through an arrow with one of the aforementioned points, generally in the north.
Legend: indicates the meaning of symbols, conventional signs or colors of a map. Allows you to read a map and interpret it.
Scale: shows the relationship between the distance represented on the map and the real distance. In other words, the number of times that reality was reduced.
Source: is the name of the entity that created the map, or the name from where it was taken. It must also indicate the date of the data collected.
Classification of maps according to theme: Thematic Maps
Classification of maps according to theme:
Thematic Maps: Physical; Politicians; Demographics; Economic and Roads.
General or Base Maps: Planispheres; Chorographic, Topographic and Plans.
Classification of Maps Regarding Scale:
Small Scale:
Planispheres;
Chorographic.
Large Scale:
Topographic;
Plans.
Thematic maps
Thematic maps: Present more specific information about a given phenomenon or subject and present information from a more simplified background.
(1)Physical: Represent natural phenomena. Ex. Hypsometric map, climate and forest areas;
(2)Demographic: Represent variables related to the population. (Ex. Resident population distribution map and population density map;
(3)Political: Represent administrative divisions. (Ex.: Country borders and map of administrative divisions);
(4)Economic: Represent economic variables. (Ex.: Gross Domestic Product distribution map);
(5) Roads: Represent road communication routes.
