Online geoprocessing gains momentum through increased online data\r<br />repositories, web service infrastructures, online modeling capabilities and the required\r<br />online computational resources. Advantages of online geoprocessing include reuse of data\r<br />and services, extended collaboration possibilities among scientists, and efficiency thanks to\r<br />distributed computing facilities. In the field of Geographic Information Science\r<br />(GIScience), two recent approaches exist that have the goal of supporting science in online\r<br />environments: the geospatial cyberinfrastructure and the geoprocessing web. Due to its\r<br />historical development, the geospatial cyberinfrastructure has strengths related to the\r<br />technologies required for data storage and processing. The geoprocessing web focuses on\r<br />providing components for model development and sharing. These components shall allow\r<br />expert users to develop, execute and document geoprocessing workflows in online\r<br />environments. Despite this difference in the emphasis of the two approaches, the objectives,\r<br />concepts and technologies they use overlap. This paper provides a review of the definitions\r<br />and representative implementations of the two approaches. The provided overview clarifies\r<br />which aspects of e-Science are highlighted in approaches differentiated in the geographic\r<br />information domain. The discussion of the two approaches leads to the conclusion that\r<br />synergies in research on e-Science environments shall be extended. Full-fledged e-Science\r<br />environments will require the integration of approaches with different strengths.
