Extended Poster Abstract: Open Source Solution for Massive Map Sheet Georeferencing Tasks for Digital Archiving
نویسنده
چکیده
Scanned maps need to be georeferenced, to be useful in a GIS environment for data extraction (vectorization), web publishing or spatially-aware archiving. Widely used software solutions with georeferencing functionality are designed to suit a universal scenario for georeferencing many different kinds of data sources. Such general nature also makes them very time-consuming for georeferencing a large number of map sheets to a known grid. This work presents an alternative scenario for georeferencing large numbers of map sheets in a time-efficient manner and implements the approach as the MapSheetAutoGeoRef plug-in for the freely available open source Quantum GIS [1].

متن کاملIntegration of Old Cadastral Maps into Up-to-date Geodatabases for Urban Planning
GeoDb are today very important tools to cope efficiently with management and planning of urban areas. On the other hand, very often cities are undergoing a fast transformation process, which could result in changing the specific nature of their districts. The availability of old cadastral maps, although in paper form, allows to reconstruct all steps of land transformation during past years. The...

متن کاملGeoreferencing Maps With Contours
In this paper, we present an overview of the georeferencing capabilities that enable registration of digital maps (raster data) with contours (vector data). This paper outlines the theory and standards used for proper geographic referencing of digital maps, and focuses on extraction of georeferencing information from TIFF and ESRI IMG raster file formats. Given 2D maps and 3D contours, georefer...
