TL;DR: The International Society for Photogrammetry and Remote Sensing (ISPRS) Technical Commission II (TC II) revisited the existing geospatial data handling methods and theories.

TL;DR: In this article, a position paper of the International Society for Photogrammetry and Remote Sensing (ISPRS) Technical Commission II (TC II) revisits the existing geospatial data handling methods and theories to determine if they are still capable of handling emerging gespatial big data, synthesises problems, major issues and challenges with current developments as well as recommending what needs to be developed further in the near future.

TL;DR: A brief survey of existing facilities for geographical information retrieval on the web is provided, before describing a set of tools and techniques that are being developed in the project SPIRIT : Spatially-Aware Information Retrieval on the Internet.

TL;DR: An overview on current approaches for the automation of generalization and data abstraction is given, and solutions for three generalization problems based on optimization techniques based on Neural Network techniques are presented.

TL;DR: The paper presents solutions for generalization problems using least squares adjustment theory, a well known general framework to determine unknown parameters based on given observations, and demonstrates the validity of this approach to the simplification of building ground plans and the displacement of arbitrary cartographic objects.
