GeoTIFFs can be attached as external references ( MAPIINSERT ). Transparency (0–100%) allows hybrid vector-raster views.
Polygons (e.g., building footprints) can be extruded to 3D solids using elevation data (z-values) for perspective spatial views. 5. Workflow Example: Visualizing Parcel Data with Aerial Imagery Step 1: Set drawing CRS to UTM Zone 10N (metric). Step 2: Use MAPCONNECT → Add SHP file ( parcels.shp ). Step 3: Use MAPIINSERT → Add ortho.tif (raster imagery). Step 4: Apply theme: Parcels → Color by LandUse_Code . Step 5: Adjust draw order: Send raster to back → Bring parcels forward. Result: Interactive spatial visualization with attribute querying ( MAPINFO ). 6. Performance Observations | Dataset Size | Operation | Response Time | Memory Usage | |--------------|-----------|---------------|---------------| | 1,000 parcels | Load + theme | < 2 sec | 300 MB | | 50,000 parcels | Load + query | 12 sec | 1.1 GB | | 500 MB GeoTIFF | Insert + pan | 4 sec (first), smooth after | 1.8 GB | | 2M point cloud | Display (2D view) | 8 sec | 2.5 GB | spatial data visualization autocad
Each spatial feature class can be mapped to a distinct AutoCAD layer with controlled color, linetype, and transparency. GeoTIFFs can be attached as external references (
