Interactive Digital Photomontage
Interactive image editing image compositing userguided optimization
2016/5/24
We describe an interactive, computer-assisted framework for combining
parts of a set of photographs into a single composite picture,
a process we call “digital photomontage.” Our framework makes
us...
Digital photography has made it possible to quickly and easily
take a pair of images of low-light environments: one with flash to
capture detail and one without flash to capture ambient illumination...
DIZI: A Digital Ink Zooming Interface for Document Annotation
Document Annotatio Zooming Interface
2016/5/24
Pen computing devices provide a natural interface for annotating
documents with freeform digital ink. However, digital ink annotations are usually
larger and sloppier than real ink annotations on pa...
Applying two dimensional Kalman Filtering for Digital Terrain Modelling
Applying two dimensional Kalman Filtering Digital Terrain Modelling
2016/5/23
Digital Elevation Models (DEMs) have been increasingly used to model the terrain surfaces to provide the 'physical bases' for environmental studies. However, DEM is subject to systematic errors, rando...
Accuracy of Digital Elevation Model according to spatial resolution
Accuracy Digital Elevation Model according spatial resolution
2016/5/23
Digital Elevation Model (DEM) is indispensable for many analyses such as topographic feature extraction, runoff analysis, slope stability analysis and so on. Beforehand such analyses, accuracy of DEM ...
Digital Orthophotos from IRS - production and utilization
Digital Orthophotos IRS - production utilization
2016/5/23
The Sweden based GAF subsidiary Observation, Mapping and Monitoring AB (OM&M) has produced ortho-images based on IRS data on a routine basis since May 1997.
Triangulated Digital Elevation Model: definition of a new representation
DEM structure DEM generation TIN regular network DEM quality criterion
2016/5/23
In this paper we discuss about the need of a new DEM representation for simulation in GIS. This leads us to analyse through quality criteria the current DEM structures. Then we propose a new DEM repre...
The scheme for the database building and updating of 1:10000 Digital Elevation Models
Geospatial data DEM Photogrammetric sampling Cartographic digitisation Specification
2016/5/20
The National Bureau of Surveying & Mapping of China has planned to speed up its development of spatial data infrastructure (SDI) in the coming few years. This SDI consists of four types of digital pro...
Digital orthophotos and map revision in national land survey of Finland
Digital orthophotos map revision national land survey Finland
2016/5/20
The production system of middle-scaled topographic maps of the National Land Survey of Finland was re-engineered in 1992-1993 when a new Topographic Data System was introduced. After that data compila...
Object-oriented modelling for the extraction of geometry, texture and reflectance from digital images
Semi-Automatic Extraction System CORBA JavaBeans GIS CSG
2016/5/20
A semi-automatic system for extracting topographic features is being migrated to an object-oriented design for better maintainability. For that purpose an object-oriented model of the extracted object...
Dubai Municipality is actively introducing digital orthophotos for solving actual planning needs. Past experience revealed that already available map products are very soon outdated due to a booming e...
Mosaicking of Digital Elevation Models derived by SAR interferometry
Mosaicking Digital Elevation Models derived SAR interferometry
2016/5/20
In the framework of the Shuttle Radar Topography Mapper (SRTM) Mission the generation of high-quality Digital Elevation Models (DEMs) with global coverage of the earth's surface is envisaged. In this ...
Digital aerial triangulation for DTM and orthophoto generation
Digital aerial triangulation DTM orthophoto generation
2016/5/20
Automatic Digital Aerial Triangulation has been implemented at the Institute of Geodesy and Cartography in 1997 on the ImageStation 6487 INTERGRAPH. Several blocks of B/W aerial photographs in the sca...
A procedure for map updating using digital mono-plotting and DTMs
procedure for map updating digital mono-plotting DTMs
2016/5/20
The production and updating of maps of the terrain surface is a procedure that can be done easily by using aerial photographs. In general this procedure needs to use expensive equipment that are not a...
