Abstract: A computer-readable storage medium comprising instructions which when executed cause a computing device to receive a request from a client to display a map projection of a spatial reference, wherein the spatial reference comprises a location and a scale, select a projected coordinate system from a plurality of projected coordinate systems based on the spatial reference and a set of business rules, generate the map projection of the spatial reference using the projected coordinate system, and send the map projection to the client, wherein the map projection is displayed on the client.

Abstract: An example method for coordinate system identification that includes obtaining an attribute and a spatial entity of a region and identifying a number of information repositories using a business rule, the business rule identified using the attribute. The method further includes accessing the number of information repositories to identify a number of coordinate systems, each of the number of coordinate systems defined for the spatial entity. The method further includes selecting one of the number of coordinate systems, transforming spatial data for the region based on the one of the number of coordinate systems to generate a map, and displaying the map including the spatial data.

Abstract: A currency dispenser packet for facilitating the sale of prepackaged foreign currency at a retail outlet includes an envelope containing a preselected quantity of a currency of a foreign country. The envelope is imprinted with a machine-readable code identifying the contents of the envelope as well as the identity of the seller. The code on the envelope is scanned or "read" at the point of sales and the read data is transmitted to a central station processor at which current foreign currency exchange rates are maintained. The processor computes the cost of the foreign currency in U.S. dollars or currency of purchase as well as the applicable commissions and transmits this information to the point-of-sale location. The packet thus allows foreign currency to be sold at locations dealing with travelers such as travel agencies, airline ticket terminals, and other outlets where such sales have heretofore not been practical.
