What is Chorochromatic technique?
Basically, the chorochromatic technique implies the drawing of bounding lines to delimit specific areas within which shading or coloring is applied to mark distinctive features [2]. Chorochromatic maps can be simple or compound.
What is Isarithmic?
From wiki.gis.com. An Isarithmic map is a type of Thematic map that represents a continuous field using line and/or region symbols to connect places of similar value. It is sometimes called a heat map, although the term heat map should only be used for one type of isarithmic map that represents density.
What is thematic geography?
A thematic map is a type of map that portrays the geographic pattern of a particular subject matter (theme) in a geographic area. This usually involves the use of map symbols to visualize selected properties of geographic features that are not naturally visible, such as temperature, language, or population.
What are examples of thematic maps?
These are maps which depict information on a particular topic or theme. The detail portrayed on a thematic map may be physical, statistical, measured, or interpreted, and sometimes requires specialist knowledge by the map user. Weather, population density and geology maps are examples of thematic maps.
What is the difference between choropleth map and qualitative map?
In a choropleth map, the variable is summarized over predetermined districts; for example, census data could be aggregated to determine the predominant language of each country in Europe. Conversely, in a chorochromatic map, the regions are drawn based on detailed locational data.
What are the 5 thematic maps?
Let us have a look at the seven most used thematic map types.
- Choropleth Map. The choropleth map is one of the most frequently used maps in Geospatial data.
- Dot Distribution Map.
- Graduated Symbol Map.
- Heat Maps.
- Cartogram.
- Bivariate Choropleth Map.
- Value by Alpha Map.

Is the Isarithmic map an isopleth map?
However, when data is areal, the isolines only approximate the change and cannot be interpreted as exact, the map is an isopleth map. Often, the data for Isarithmic mapping is gathered from distributed sample points, leaving an absence of information between these locations.
What do you call An Isarithmic density map?
It is sometimes called a heat map, although the term heat map should only be used for one type of isarithmic map that represents density. In general, these maps are used to help visualize continuous data sets by utilizing color, especially hue and value.
What kind of data is used in Isarithmic mapping?
Isarithmic mapping often uses control points or data for an event pulled from recorded data at certain locations. These control points have two types of data; the first known as true point data and the second known as conceptual point data.
