Besides, as a reference, the slides on DEM generation from stereo-pair RADARSAR 2 without GCPs are advised to read at http://earth.eo.esa.int/pub/polsarpro_ftp/POLinSAR2011/Wednesday26/Methods&TheoreticalModelling/2_Toutin_9_05.pdf

leslie, In practice, you have an effective way to solve this challenge, i.e., to fill the gaps of the field data using IFSAR. How? Please refer to Fill Voids in DEM

Honestly, you are facing a challenge. From your snapshot, my view is: Your higher-resolution DEM derived from IFSAR is not reliable. Do you have any accuracy report on this dataset from data provider? Are those SAR images from space-borne RADARSAT or other? Generally, without rectification along with GCPs or other references, this higher-resolution DEM data should NOT be unified with your DEM from surveying, which is more reliable and accurate... The best way to do the rectification is that it should be re-started from two SAR pairs, before generating DEM.

It depends on the accuracy of your two contour files. For example, if both spatially are accurate enough (i.e., match on the same values of contours), the combination of two vector files (the GP tool ‘merge’) is first step for GIS uses; However, if distorted on same values of contour, the lower accuracy of 1:10000 contours from IFSAR should be spatially adjusted to match the higher accuracy of surveying contours 1:5000 before merging..

Refer to Supported Formats ArcGIS Data Interoperability supports various proprietary formats and protocols as well as standardized formats from OGC. The GML (simple features) and WFS core standards are enabled using the extension, with no licensing required.

It is a good question, louise, honestly, without checking your data, it is also challenging to offer the best answer to your question. however, ESRI published a paper on empirical Bayesian Kriging. please refer to http://www.esri.com/news/arcuser/1012/files/ebk.pdf if more deep required, pls share your data and see if we can help more specifically

First of all, your intention will be a research study, rather that a workflow from ArcGIS. Please refer to 'Object-oriented' Change Detection in Operation Secondly, nice to read the paper at Variations in northern vegetation activity inferred from satellite data of vegetation index during 1981 to 1999 - Resear… Pay attention to approaches in this study

From time-serial images (1998 – 2014), you can define the ‘spatial variation’, in addition to ‘temporal variation’ However, advisable to use other methods like Intervention Analysis (IA)…
