ESRI (CA, USA) has released ArcGIS for AutoCAD, a free AutoCAD application that allows CAD users to visualise and query GIS data within the CAD environment without conversion. ArcGIS for AutoCAD accesses dynamic georeferenced ArcGIS Server map services and displays them in the AutoCAD drafting environment.
The map service metadata is accessible in the standard AutoCAD Properties window, and the map feature attributes can be viewed via the Identify tool. All vector, raster, and imagery formats that ArcGIS Server supports can be viewed in the CAD environment.
With ArcGIS for AutoCAD, CAD users can:
- dynamically interact with live GIS maps, displaying GIS symbology and data structures in CAD.
- include the results of GIS analysis in their CAD designs.
- include GIS basemaps in their CAD products.
- access feature attributes in CAD directly from the underlying GIS databases using the Identify tool.
ArcGIS for AutoCAD requires ArcGIS Server 9.2 and AutoCAD 2007.
The terrain was prepared from aerial ortho-image of 30 cm resolution. Lidar derived Canopy Height Model was worked at 15 cm resolution. For keeping the uniformity with Lidar derived layers, the ortho-image was used at 15 cm pixel size.
