Imaging Geodesy and Infrastructure Monitoring

Dear Colleagues,

The surge in the availability of high spatial resolution Synthetic Aperture Radar (SAR) data has allowed ever increasing use of modern SAR sensors for mapping applications and investigating deformation processes related to natural and man-made hazards. Significant improvements in interferometric, polarimetric, and tomographic processing, coupled with development of high-resolution SAR sensors aboard missions such as Italian COSMO-SkyMed (CSK) and German TerraSAR-X (TSX), have created new opportunities for detailed imaging of buildings and analyzing motion and thermal changes related to infrastructure in urban environment. Very high-resolution interferometric methods are one side of the opportunities, the other is the dramatic increase of absolute geometric localization accuracy of these methods which can reach the cm-regime. However, the full potential of space-borne and ground-based SAR technologies within civil and surveying engineering community is still unrecognized.

The main objective of this special issue is to present the progress, and state-of-the-approaches in algorithm development and scientific exploitation of SAR data to retrieve information about infrastructure. Contributions reporting on SAR tomography and compressive sensing, combination of SAR/InSAR data with other optical and geotechnical sensors for urban mapping and improving the efficiency of remote sensing products for operational monitoring, integration of SAR/InSAR products with numerical and analytical geotechnical models for stability analysis of infrastructure, polarimetric analysis of urban environment as well as contributions to the achievement and use of cm-level absolute geolocation accuracy are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
