Three Thematic Maps
Thematic maps are maps that show a particular geographic region, but also have a specific theme that they cover. Some of the more commonly used thematic maps show, but are not limited to, cultural, physical, economic, or even political aspects of a given region. Following this paragraph are three examples of thematic maps that elaborate on different aspects of Russia.
Choropleth Map
A choropleth map is a map that uses differences in shading, coloring, or the placing of symbols within predefined areas to indicate the average values of a property or quantity in those areas.

Topographic Map
A topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, using contour lines but, historically, using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features.

Climatic Map
A climatic map is a map that shows the geographic distribution of the monthly or annual average values of climatic variables - i.e., temperature, precipitation, relative humidity, percentage of possible sunshine, insolation, cloud cover, wind speed and direction, and atmospheric pressure over regions ranging in area from a few tens of square kilometers to global. To minimize biasing the data because of one or two periods with abnormally high or low values, the data are averaged over at least 30 periods, whether they be months or years.
