SERVER IMPLEMENTED GEOGRAPHIC INFORMATION SYSTEM WITH GRAPHICAL INTERFACE

摘要

Example embodiments described herein pertain to a geographic information system (GIS), configured to obtain geospatial data representing a geographic area, assign a projection and coordinate system to the geospatial data, apply a transformation to the geospatial data, and generate a tile cache based on the transformed geospatial data, the tile cache including the determined projection and coordinate system.

主权项

1. A method comprising:
receiving geospatial data at a server, the geospatial data identifying a geographic area that includes a first depiction of one or more landmarks, the one or more landmarks represented in the geospatial data by location data that defines locations of the one or more landmarks within the geographic area; retrieving a base map that includes a second depiction of the one or more landmarks and corresponds to the geographic area identified by the geospatial data based on the location data of the one or more landmarks, the base map having a projection and coordinate system; assigning the projection and coordinate system to the geospatial data; applying a transformation to the geospatial data based on the projection and coordinate system; and generating a tile cache based on the transformed geospatial data, the tile cache including the projection and coordinate system.
