Automated GIS data collection and update
نویسنده
چکیده
This paper examines data from different sensors regarding their potential for an automatic change detection approach. After a brief discussion of the used approach, results are shown on examples of data from several sensors: scanned analogue aerial photos, an airborne digital line scanner (DPA camera system), the Indian satellite IRS-1C, the MOMS2P camera and from a laser scanning system as an additional information source. The GIS data which have to be updated are from the German national topographic cartographic database (ATKIS) and were captured in the scale of 1 : 25,000.

Data Mining for Automated GIS Data Collection
The automatic analysis of spatial data sets presumes to have techniques for interpretation and structure recognition. Such procedures are especially needed in GIS and digital cartography in order to automate the time-consuming data update and to generate multi-scale representations of the data. In order to infer higher level information from a more detailed data set, coherent, homogeneous struc...
متن کاملPhased Disaster Data Collection System using Cooperation between Mobile Robots and Spatial Temporal GIS
This paper describes a phased earthquake data collection system using the cooperation between mobile robots and a spatial temporal GIS (Geographic Information System). This proposed method features three-phased data update and models a “change region” as KIWI+ building object data. The 1st update sends the robot position and the omnidirectional images as soon as possible. At the 2nd stage, 3D (...
متن کاملTrends and Perspectives of Automated GIS Data Collection
In this paper we discuss trends and perspectives of automated data collection for Geographic Information Systems (GIS). We focus on aerial imagery and employ road extraction for the examples. The paper is split into three parts: In the first we present major findings for the (fully) automatic extraction of buildings, roads, and other topographic objects in the form of a model and a strategy. In...
