1. A navigation database system comprising a computer programmed to:
- acquire route data in a first format for a route, the route data comprising a plurality of route parameters for each of a plurality of route locations;
re-format the acquired route data in the first format into a second format different from the first format;
filter the re-formatted route data into a route dataset having a lesser number of route locations than the number of route locations in the acquired route data;
store the route dataset in computer memory;
identify a portion of the survey data wherein two successive locations of the number of locations in the first route are separated by a distance that is greater than a threshold multiple of the average distance between successive locations of the number of locations in the first route; and
display the identified portion of the survey data to a user.

Abstract
A computer-readable storage medium having stored thereon a computer program including instructions, which, when executed by a computer, cause the computer to acquire route data in a first format for a route, the route data comprising a plurality of route parameters for a plurality of route locations. The computer is further programmed to re-format the acquired route data in the first format into a second format different from the first format, filter the reformatted route data into a route dataset having a lesser number of route locations than the number of route locations in the acquired route data, and to store the route dataset in computer memory.

1. A navigation database system comprising a computer programmed to:
-
acquire route data in a first format for a route, the route data comprising a plurality of route parameters for each of a plurality of route locations; re-format the acquired route data in the first format into a second format different from the first format; filter the re-formatted route data into a route dataset having a lesser number of route locations than the number of route locations in the acquired route data; store the route dataset in computer memory; identify a portion of the survey data wherein two successive locations of the number of locations in the first route are separated by a distance that is greater than a threshold multiple of the average distance between successive locations of the number of locations in the first route; and display the identified portion of the survey data to a user. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method comprising:
-
obtaining survey data in a first format for a first route having a number of locations, the survey data comprising a plurality of route parameters for the number of locations; assembling the survey data in the first format into a series of tables having a second format different from the first format; reducing the number of locations in the survey data for the first route based on a set of criteria; storing the reduced number of locations in computer memory; identifying, via a processor, a portion of the survey data wherein two successive locations of the number of locations in the first route are separated by a distance that is greater than a threshold multiple of the average distance between successive locations of the number of locations in the first route; and displaying the identified portion of the survey data to a user. - View Dependent Claims (10, 11, 12, 13)

14. A non-transitory computer-readable storage medium having stored thereon a computer program comprising instructions, which, when executed by a computer, causes the computer to:
-
receive survey data in a first format for a route, the survey data comprising a plurality of route parameters for a plurality of locations in the route; convert the received survey data into a second format different from the first format; process the converted survey data into a dataset having fewer locations in the route than the plurality of locations in the route from the received survey data; store the dataset in computer memory; identify a portion of the survey data wherein two successive locations of the number of locations in the first route are separated by a distance that is greater than a threshold multiple of the average distance between successive locations of the number of locations in the first route; and display the identified portion of the survey data to a user. - View Dependent Claims (15, 16, 17, 18)
