Establishment of Map Renewal Technique for Local Government by Using Real Time GIS
Mobile Mapping System Database Updating GPS-Assisted Photogrammetry
2015/12/17
Much local government has been utilizing a large-scale digital map using Geographic Information System (GIS). However, the maintenance and renewal of a map database need much labor and time. Moreover,...
Quality Inspection and Quality Improvement by Map Fusion
Data Fusion Matching Quality Inspection
2015/12/2
In this paper a new approach for quality measurement and improvement using map matching and map fusion is introduced. In the first part we describe a matching model based on “Buffer growing”. The matc...

Segmentation building detection airborne laser scanning
2015/3/24
Laser scanner data is being increasingly used to obtain topographical and object height information for mapping and GIS tasks.
Valuable information can be derived of the terrain and objects of a reg...
THE IMPACT OF CONFORMAL MAP PROJECTIONS ON DIRECT GEOREFERENCING
Aerial Triangulation Impact Analysis Mathematics
2015/3/24
If an aerial-triangulation (AT) is performed in the National Projection System (NPS), then the conformal map projection (which is
the base for the NPS) effects the results of the AT by raising three...
