An automated computer geocoding system and method is described having a plurality of geographic datasets stored in a computer memory. The geographic datasets include at least one point level dataset, street level dataset, and geographic level dataset. As output, geocoded data is provided with positional accuracy indicators. In a first step, an address to be geocoded is received by the system. The system determines whether corresponding geocode data exists in one or more of the geographic datasets. A geographic dataset is selected that provides a highest level of resolution and that also includes corresponding geocode data for the address. A geocoded coordinate for the address is output, as found in the geographic dataset that was selected. An offset value for the geocoded coordinate is calculated and output with the coordinates. The offset value is determined as a function of geographic characteristics of the geographic dataset that was selected.

System and method for geocoding positional accuracy

A reverse geocoding system and method processes a point level dataset and a street segment dataset to determine an address for a particular latitude and longitude of an input point entered into the system. A determination is made if the point level dataset contains a point level data address match to the entered latitude and longitude data within the closest street segment and without crossing the street segment. Any such point level data address match is output. When no such point level data address match is made, the system computes an interpolated address from a range of addresses of the closest street segment in the street segment dataset based on the entered latitude and longitude of the input point in relation to said range of addresses for the closest street segment. The interpolated address from the closest street segment in the street segment dataset is output.

Reverse geocoding system using combined street segment and point datasets

Assignment of point level address geocodes to street networks include the steps of entering address data and collecting candidate point data records and segment data record matches for the entered address. Each point data record includes address elements and also includes a geocode. Each segment data record includes a centerline between segment record data points. A determination is made if there is at least one point data record match for the input address. The best point record match for the input address is selected when at least one point data record match is made. The address elements from the point record are compared to any collected segment data records. A determination is made of the best segment record match to the selected best point record and the best segment record match is selected. The selected best segment record is employed and the bearing and distance from the selected best point record is calculated to a point on the centerline of the selected best segment record to determine a geocode for the centerline point.

Method for assignment of point level address geocodes to street networks

A method for processing two different types of geographic address data sets to establish candidate matched data includes entering address data into the system and accessing a point level address data set. A determination is made if the point level data set contains an exact match to the entered address data. Any exact address data match from the point level data set is output. Candidate address data matches from the point level data set are saved when no exact match is determined as existing in the point level data set. A centerline address data set is accessed and a determination is made of candidate address data matches from the centerline address data set. Candidate address data from both the point level data set and the centerline data set are scored and matched. A system for geocoding and address hygiene includes a processing system with an input and an output system coupled to said processing system. A point level data set is coupled to the processing system. A centerline data set is coupled to the processing system. A cascade geocoding scoring and matching engine is coupled to the processing system.

Geocoding and address hygiene system employing point level and centerline data sets

A reverse geocoding system and method processes a point level dataset and a street segment dataset to determine an address for a particular latitude and longitude of an input point entered into the system. A determination is made if the point level dataset contains a point level data address match to the entered latitude and longitude data within the closest street segment and without crossing the street segment. Any such point level data address match is output. When no such point level data address match is made, the system computes an interpolated address from a range of addresses of the closest street segment in the street segment dataset based on the entered latitude and longitude of the input point in relation to said range of addresses for the closest street segment. The interpolated address from the closest street segment in the street segment dataset is output. The street segment dataset may also contain unranged street segments without ranges of addresses.

A system and method of determining elevation values includes inputting a location into a geocoding system having a segment data set and determining the closest segment in the data set to the location. A data set of elevation data the closest segment is accessed and a determination is made of an elevation value for each of two elevation points associated with the closest segment. The elevation value of the location is determined based on interpolation of the location in relation to each the two elevation points and the elevation value of each of the two elevation points. The determined elevation value for said input location is output. The offset distance of the location from the closest segment may be determined and a slope applied to the offset distance to determine an elevation gain or loss for the location due to the offset distance of the location from the closest segment.
