Distinct molecules called agglutinogens (a type of antigen) are attached to the surface of red blood cells. There are two different types of agglutinogens, type A and type B. Each type has different properties.
MDB: Geodatabase. The geodatabase is a collection of geographic datasets of various types, with the most basic types being vector, raster, and tabular data. There are three types of geodatabases: file, personal, and ArcSDE. Geodatabases are the native data format for ESRI's ArcGIS.
ArcGIS canât natively read KML files, so in order to access the geographic data, you will first need to first convert the KML file into a personal geodatabase (.gdb) using a tool provided within ArcGIS called KML2Layer.
