EVS-Islands

The above map shows some of my completed island mapping projects. Each icon contains the name of the primary island associated with the project and a link to the post. Once all of my projects are posted, the map will be covered with icons. To productively use the map, zoom into a region of interest. Then select an icon.

Each of my maps is constructed of numerous layers of information. All of the layers are vector files. I will make these files available upon request. You are free to use them with certain restrictions - 1) Don't sell them. You can use them on research projects, post them to your website or things of that nature. If you aren't sure about the use of my maps, drop me a line and we can discuss your idea. 2) Give me credit when you use my vectors or images of my maps. Credit them to Peter Minton @ EVS-Islands

If I have the island vector file(s) and based upon your need, I will make them available. Images of my maps are yours to download and use, with the above restrictions applicable. Enjoy!

How to Improve the Appearance of the Bathymetry of the Caspian Sea

Caspian Sea - Marplot Map with Isobats (1:65-km)

The last couple of evenings I converted Caspian Sea isolines into isopolygons. Each color of blue represents another depth. The deepest point within the Caspian Sea is in the southern portion at over -900 meters. Just to the north of that depth is a stretch of sea floor from Baku, AZ to the Turkmenistan shore that is loaded with oil. It is an area that has been worked extensively and continues to be explored and exploited.

The northern Caspian Sea is another area of extraordinary oil deposits. It is very shallow (5-meter or less). The problem with the oil throughout the Caspian is getting it shipped to market. The oil currently flows through pipelines into Russia and another newer pipeline that will transport the oil into Turkey. The Caspian Sea has lots of oil, but it is difficult getting the oil into western markets.

The biggest challenge with this project was determining the colors to use within the various isopolygons. I believe the colors you see here provide a solid presentation. However, Marplot is rather weak on labels.

For the most part, the labels show up and are readable, but quite often they get swallowed by a layer of information. I could apply labels as a separate layer of information. I would do that if this map were a commercial product, but since it is my product for my enjoyment, I'll leave the labels as they are.

Enjoy!
