Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional GIS applications load multiple image tiles to generate high-resolution map displays, then the display quality and resolution are improved, but the processing time and resource consumption increase significantly
Solution Approach 1:
The system pre-processes and stores image data in an optimized format with pre-calculated blending parameters before runtime. When a map display is requested, the pre-processed tiles are immediately retrieved and combined using stored parameters, eliminating the need for time-consuming real-time processing and resampling operations.
Solution Approach 2:
The map display is divided into multiple image tiles that are processed and stored independently. Each tile contains pre-computed data for its specific region, allowing parallel retrieval and combination without processing the entire map as a single large image, thus reducing overall processing time while maintaining high resolution.
2Speed
If traditional systems store and process large image data sets in memory, then the access speed is improved, but the memory resource consumption increases
Solution Approach 1:
The system stores image tiles at optimized local resolutions rather than uniformly high resolution across the entire dataset. Each tile is stored with the specific properties and resolution needed for its display context, allowing efficient memory usage while maintaining high display quality where needed. The blending parameters are stored locally with each tile for immediate access during combination.
Solution Approach 2:
Large image datasets are segmented into smaller manageable tiles that can be selectively loaded into memory based on display requirements. Only the tiles currently needed for the visible map area are loaded into memory, while other tiles remain on disk or external storage, significantly reducing memory consumption while maintaining fast access to required data.
3Adaptability or versatility
If map servers process and combine multiple image tiles in real-time, then the display flexibility is improved, but the server load and network bandwidth consumption increase
Solution Approach 1:
Blending parameters, transformation matrices, and combination rules are pre-calculated and stored with each image tile during the data preparation phase. When generating map displays, the server simply retrieves these pre-computed parameters and applies them during tile combination, eliminating the need for complex real-time calculations and reducing server processing load while maintaining display flexibility.
Solution Approach 2:
Instead of processing and transmitting multiple high-resolution original tiles, the system uses pre-processed copies of tiles with embedded blending information. These copied tiles contain all necessary data for seamless combination, reducing network bandwidth consumption while allowing flexible display generation on the server side.
