I was originally a River Habitat Surveyor in the UK but I drifted into GIS and its application in mapping and geo-processing of river habitat sites. I would now class myself as an ArcGIS desktop developer. I have spent over a decade developing tools in ArcObjects the building blocks of ArcGIS. As a home project and born out of my interesting in mapping data along rivers I developed RivEX a tool for processing river networks.

My work at GeoData has covered topics as diverse as satellite classification, forestry, census, marine traffic, historic monuments, cycle surveys, mobile mapping and numerous projects extracting and analysing river related information.

comment Weighted Overlay final raster to indicate inputs
@ChrisW - yeah that was how I was envisaging it, 2 rasters and when they use the info tool they query both layers at the same time.

comment Weighted Overlay final raster to indicate inputs
You would create 7 new rasters from your 7 weighted rasters. You reclassify them into the coding scheme I suggested and add those together. That gives you your who contributed raster. You then use your original 7 rasters in your weighting analysis as you have. So you have two final rasters one your analysis and the other I'm suggesting. You do not do your weighting analysis with the reclassified rasters.

Would help if you had uploaded a screen shot of the model as I think what @SIslam is suggesting should work especially if you make the output a precondition to any downstream processing.

comment Creating bathymetric contours using shoreline point data and transect point data
Can you send your surveyors back and get some North-South transects? I'm no expert in this type of analysis but I thought a more zig-zag transect was usually the way its done?

comment How to set feature vertex Z from an intersecting feature's Z?
So not only do you want to get the Z value from the red line you also want to edit the geometry of the blue line by inserting a vertex and assigning it's Z value?

comment Adding multiple model outputs to merge tool in ModelBuilder?
@Chuckadillus both approaches will work, just wanted to say I think the second approach would be the quickest model to knock out rather than dragging 21 tools into model builder and setting each one..

comment How to create a new mosaic dataset for every new raster created with modelbuilder?
Ok so it sounds like you want to "stack" the rasters into a single dataset? Have a look at the composite band tool? Alternatively look at the multidimensional Tools, you can stack rasters in what is called the netCDF format. Have a look at this thread

Is there always a vertex at the intersection of the two lines?

comment How to create a new mosaic dataset for every new raster created with modelbuilder?
I'm trying to get my head around what your text files represent: are they tiles or whole areas? So the output of this model are rasters generated from your text files which are slices of a depth OR are they text files of areas within a slice (depth)? For example 4 text files cover the entire area but at a specific depth and you are saying you can have between 20 to 100 "tiles" within a depth slice? Which is it?
