Parcel data acquisition and processing

A method of incorporating parcel data into a database, comprising:

• receiving parcel data from a first source, said parcel data including boundary coordinates;
• converting the parcel data from the first source into a format for storage in a common format database;
• receiving parcel data from a second source;
• converting the parcel data from the second source into the format for storage in the common format database, including
• projecting the parcel data into a common projection,
• checking spatial accuracy of the projected parcel data,
• integrating the projected parcel data with data to form, integrated parcel data, and
• repairing geometries of the integrated parcel data;
• storing the converted parcel data from the first source and the integrated parcel data from the second source in the common format database;
• removing, by a processor, redundant parcel data between the converted parcel data from the first source and integrated parcel data from the second source;
• and
• retrieving parcel data from the common format database in response to a user request,
• wherein storing the converted parcel data from the first source and the integrated second source in the common format database includes
• receiving an indication to add the converted parcel data from the first source and the integrated parcel data from the second source to the common format database, and
• loading the converted parcel data from the first source and the integrated parcel data from the second source into the common format database using a spatial database interface.
