On-the-fly review for "last-minute" submission (paper submitted without reference to the OGRS 22016 collection):
- In the abstract you say that "this paper presents a prototype for distribution (“tiling”), aggregation (“stitching”) and processing of Big Geospatial Data focusing the distribution and processing of raster data type." But in fact, in the "Method" section, your paper mentions previous works, and development perspectives, as well a a very rough description of the modules constituting the IQLib.
- Compared with the title, you paper rather reviews solutions than implements the geoprocessing of Geospatial Big Data in an open source distributed computing environment like your title suggests.
- As far as I understand, the table you propose in the paper is an original contribution, and the text should therefore artculated around it; but the role of this table is not really clearly described in your text.
- the global structure of the text is somewhat confusing (background - methods - conclusions). Your original table is in the background section (why?) contains a part of state of the art, the conclusion is rather a discussion.
According to me this text requires significant improvements and cannot best accepted for OGRS under this form. I suggest to develop the core of the texte around the possible use/role of your summary table, strongly improving the description of the different categories.
Introduction: "Furthermore, we introduce an own data and metadata catalogue enables to store the “lifecycle” of datasets, accessible for users and processes." Wording.
