How To Read A Flow Pattern Map
In this example, we use the census data. Essentially, this displays what, where and how much does the United States export to other countries.The for QGIS is a quick and easy way to generate flow maps of your own. When you download the plugin, it comes with test data that you can use as a template.

This can be seen in the general proportions: Source Sans Pro has been designed with a more generous width than many other comparable gothics, and its shorter majuscule letters, combined with minuscule letters with longer extenders, create a more pleasant reading texture in longer text passages.
But essentially, it boils down to these two text files as inputs:. A list of nodes with their. A square matrix of magnitude values with each row corresponds to a ‘from’ node and each column corresponds to a ‘to’ node.After running the plugin, the results look good. As you can see, line thickness depicts magnitude of that movement. This means that the United States biggest trading partners are its neighbors in the north (Canada) and south (Mexico). 2 Distributive Flow MapsAlthough similar to radial flow maps, distributive flow maps branch off to their destination.

It’s not the necessary route that is being traveled. But it’s an abstract way how this commodity or information travels from an origin to multiple destinations.For example, the English Coal Exports 1864 uses a distributive flow map. Coal exports diffuses from its origin in England to multiple destination almost like curled fingers.The tool you want to download to create this type of map is a customized in ArcGIS. Given an origin and multiple destinations, this tool uses cost distance and impedance to generate a distributive flow map for you. 3 Network Flow MapsNetwork flow maps show movement along an established network usually based on transportation or communication inter-connectivity. It uses the network information and attributes to delineate the amount of flow in the map.For example, shows the average daily traffic in a given road network.
These linkages can use line thickness and color for magnitude.Another example is a network flow map that you see for airline companies. Heathrow Airport serves flights to 84 different countries in the world. With the focal point centered at Heathrow, 84 flow lines would radiate to each possible destination.
Drainage is the outflow of water through the system of natural riversThe following are hints to follow when you describe drainage in topographical map. Divide the map into drainage basins using compass directions. Note that the drainage basin is an area drained by single river system. In each drainage basin explain the drainage pattern which the river system in the basin take. The common river drainage pattern are-Dendritic drainage pattern-Radial drainage pattern-Trellised drainage pattern-Centripetal drainage pattern. For each drainage basin explain how the rivers drain the relief region i.e highlands, lowlands and plateaus. At this part state the direction of the flow of the river, where the river is pouring its water and whether the area is well drained or not.

The area is well drained when there is no swamps or marshlands and is not well drained when is waterlogged areas.Show more Show less.
