Thoughts - VMAP Layers in My World Shorelines Map
Dar es Salaam - VMAP Layers (1:2,000,000)
I spent yesterday working with VMAP data. VMAP is the new Digital Chart of the World (DCW). It contains layers of information in vector format. The entire world is contained in 4 files V0eur, V0noa, V0sas and V0soa. Global Mapper brings in all or individual layers of information. I decided that I wanted my World Shoreline map to contain some of these layers. I reformatted and loaded: Global Bathymetry, Elevation lines (contours), airfields (almost 10,000) and metro area polygons that delineate populated areas.
Dar es Salaam - VMAP Layers (1-1,000,000)
This is the classic scale for the DCW, now called VMAP. This scale is able to accomodate a number of layers of information: World Vector Shoreline, airfields, metro areas, roads (green), railroads (red), name labels and water/land contours.
Dar es Salaam - VMAP Layers with Prototype Global Shoreline (1:125,000)
This is Dar es Salaam at 1-inch : 2-miles. More name labels show up at this level of zoom. The PGS consists of great detail and gaps due to reputed cloud cover. It makes me want to digitize a shoreline to EVS precision.
The additional layers of data are informative. They bring my World Shoreline map up to about 5-gigabytes in size with over 190-layers of unique information.
If you would like to know how I worked the VMAP data, drop me a line and I'll explain.
Now I remember what I wanted to tell you. This whole project began with a look at Europa Technologies' $5,595 one-year license Global Discovery, their premier digital world reference map. This mapping package consists of a number of DCW layers - free information that Europa Technologies repackage and sell. More power to them! I won't buy their mapping package, but if there are consumers that require it, sell it to them. Or those consumers can do like I did and make their own World Map. It takes time and very little money (Global Mapper @ $199). And it's easy!
Enjoy!
