A system and method for wireless network planning utilizing raster data, stored and manipulated in raster data planes (204 212) and vector data (522) stored and manipulated in vector data planes (528 532). The invention increases the accuracy of network planning by simultaneously utilizing vector data planes (528 532) and raster data planes (204 212) to perform computations using vector features contained within map pixels (604). The disclosed method makes it possible to perform accurate computations such as propagation loss to vector points (602) contained within map pixels (604). Accuracy is further increased because other characteristics such as received power, elevation, and best server can be computed to the vector features rather than processing them with traditional raster resolutions.
