Greetings All,
This post is all about flow line maps, and this weeks exercise Cartography assignment involving creating a flow line map. The objectives for this week were simple, create a flow line map using proper design techniques, calculate the appropriate / proportional line widths, and apply style and visual effects utilizing Corel Draw x7. The map below was created entirely in Corel Draw, with two base maps of the Worlds Countries, and a choropleth of United States immigration provided by UWF.
Flow Maps defined: These are maps which are used to depict the movement of some phenomena between various geographic locations, most often utilizing lines of varying widths or tones to represent how much movement there is. Further, the map below is sub-categorized as a Distributive flow map. That is a map focusing on the movement of commodities, people, or ideas between geographic regions. This is why we are using this style of map to look at Immigration to the United States in 2007 as the main theme.

Here is my flow map, broken down into three parts; the main map, inset map, and the main map legend.
Overall I wanted to maintain a certain simplicity with a light background to not detract from the focus elements, Ie the flow lines. There are two main stylistic effects employed. The drop shadowing which is applied to the flow lines as well as the countries in the main map. These are to help break up the figure ground. The countries become figure to the ground that is the oceans while the flow lines which are so much more bold are still figure to the ground that is the rest of the main map.
The inset map features a choropleth of Percent of total immigrants by state, which is shaded in tones similar to the background. I wanted to keep this area de-emphasized compared to the main map. However i wanted to ensure the data you are looking for becomes readily apparent. I utilized beveling in the states with the highest percentage values. I chose to do this because there are only 11 states in the upper 4 of 5 classes for the classification method used. This made it easier to distinguish just these states and not wash out large areas with too much bevel. The bevel height was adjusted to reflect lower to higher while maintaining a sequential color scheme.
The third pane with the map legend simply highlights the flow lines through proportional width while also specifying the total immigrants per region. In incorporates the same effects as the main map, predominately the drop shadow.
I hope you enjoy my flow map, thank you.

Hello,
ReplyDeleteI like your map a lot. I also want to produce a map showing product flows from the supply locations to demand locations (many to many locations). I have tried several ways but it seems like there is no in-built tool in GIS to produce this kind of map. It will be very helpful if you could give me any lead on this! Thank you.
Which may be what is more an outstanding present that i genuinely relished reading through. It's not possible regularly that marilyn and i handle the chance to know anything. online geomatics assignment help
