[Termes IGN] précision du positionnementRésumé : (Auteur) Local governments frequently use parcel maps or other spatial data for decision-making, but much of this data is often inaccurate and outdated, producing a negative influence on the expected outcome. Remote sensing can provide accurate and current high-resolution imagery. However, one major bottleneck to the integration of high-resolution imagery into existing geographic information systems is the issue of positional accuracy of the existing line-work within the vector GIS database, making it difficult to match with imagery. This paper presents a vector-to-imagery conflation approach to improve the positional accuracy of digital parcel maps by conflating the vector parcel maps to make it consistent with high-resolution imagery. Road intersections are automatically extracted from imagery and used as control points. A relaxation labeling algorithm is used to find the matches between the two road intersection point sets from vector and imagery. The links are created from the matched point pairs and are used to perform a piecewise transformation. The test results show that this approach can improve the accuracy of vector parcel maps significantly. It is a very cost-effective method and has great potential to save considerable time and money for local governments to upgrade their inaccurate vector datasets.

[Termes IGN] villeRésumé : (Auteur) In urbanized areas of the developed world, light detection and ranging (LiDAR) exists alongside a wealth of other geospatial information. Despite this bounty, high-resolution land cover is still lacking in many urban areas. This can be attributed to the complexity of many landscapes, the volume of available data and the challenges associated with combining data that were acquired over differing time periods using inconsistent standards. Object-based approaches are ideal for overcoming these limitations. We describe the design, development and deployment of an object-based system that incorporated LiDAR, imagery and vector data sets to develop a comprehensive, multibillion-pixel land-cover data set for the City of Philadelphia. A novel approach using parallel processing allowed us to distribute the feature extraction load to multiple cores, providing massive gains in efficiency and permitting continual modification of the expert system until the accuracy goals of the project were achieved.

[Termes IGN] partitionnementRésumé : (Auteur) The integration of multi-source earth observation data has become one of the most important developments in photogrammetry. A combined adjustment with linear array and frame array imagery (CALFI) is established in this paper. The mathematical model of CALFI is based on the conventional single-source bundle adjustment. A revised recursive partitioning technique is utilised to solve the large normal matrix of CALFI; the orientation parameters of the linear array imagery are arranged at the border of the reduced normal matrix to save both memory and computation time. The experimental results on simulated data show that both the accuracy and the condition index of the CALFI model are superior to the conventional bundle adjustment model with either linear array or frame array imagery separately due to the higher redundancy.

[Termes IGN] image à très haute résolutionRésumé : (Auteur) A method for automatically estimating the transformation parameters between road centre-line vector maps and high resolution satellite images is proposed. The advantages of the method are that global image feature extraction is avoided and feature extraction and matching are achieved simultaneously by using the vector data as guidance. The road width, as estimated by the algorithm, together with the road direction are used as constraints to refine the matching results. Arbitrarily chosen road nodes contribute to improving the adjustment. Map-to-image matching has advantages over image-to-image matching and could be a good method for the rapid updating of geographical information system (GIS) data.

[Termes IGN] spécification de produitRésumé : (Auteur) The Geospatial Information Authority of Japan [formerly the Geographical Survey Institute of Japan] (GSI) began the publication of Digital Maps (Basic Geospatial Information) on July 30, 2012 as a survey result of vector data mainly composed of 'Digital Japan Basic Maps', the data sets of maximum-scale geospatial data covering the whole of Japan. Since Digital Maps (Basic Geospatial Information) are basically provided online, they can offer new information on a daily basis as a result of surveys that reflect major changes to the land, compared to traditional survey results. However, it is necessary to use special software in order to utilize Digital Maps (Basic Geospatial Information) as map data. So the online publishing of 'Digital Topographic Map 25000' (hereinafter referred to as 'Digital Topographic Map') began on August 30 2012 so that map information that immediately reflects major changes to the land can be used more conveniently as a survey result in a raster image file format on a 1:25,000 scale level. Using this Digital Topographic Map, maps can be created that optimize the benefits of online publication by selecting the display range and size, as well as some display colors of map symbols and representations according to the intended use of the purchasers. Another feature is the ability to always provide the latest version of map images, as the images are generated from the Digital Japan Basic Map of Japan database as soon as the order is received from the purchaser, rather than from archived images. This paper presents the concept and specifications of the 'Digital Topographic Map' as the new survey result, and an overview of the content of the development of the system being provided.
