Mission Planning Tip: VMap Level 1
Until now we've looked at VMap0 as a replacement for the Vector Map and as a map itself. Today we'll expand our VMap data and begin using VMap1 over Southern California. You can download the VMap1 CD from http://geoengine.nima.mil/ftpdir/archive/vpf_data/v1097.tar.gz. There's 234 VMap1 CD's and NGA has posted 55 for public download on the Internet. Of course all the data is available on other networks (OSIS/SBU, SIPRNET, JWICS) or via DLA. To download sample data on the public internet your best starting point is here.
After downloading your VMap archive unzip the file and add it as a FalconView map path using the procedures you followed with VMap0.
Today we'll start at San Nicholas Island (NSI/A). A VMap0 map at 1:250K scale looks like:
Going back to the Map - Options - Vector Smart Map... change the options to use VMap1:
In this case as you pass 1:500K you'll switch from VMap0 data to VMap1 data. San Nicholas Island looks like:
By comparison the JOG chart looks like:
Not surprisingly the VMap1 data looks a lot like the JOG - that was the database's data source. If you keep your scale on VMap1 or VMap0 your performance will be pretty good as you move around the map, but if you swap back and forth you'll force FalconView to reload the alternate database files and there will be a noticeable delay.
You can use VMap like any other chart scale including using the FalconView page layout tools to produce printouts. Drop a single page on the map then right click on the frame's border (yellow line) and select Single Page Properties...
The Single Page Properties includes a selection for "Category". Categories include Raster (CIB, CADRG, GeoTiff etc.), DTED and Vector Smart Map.
Once you select Vector Smart map select the scale:
A Print Preview shows what your VMap printout will look like:
